Deepcool Captain 240 Pro CPU Liquid Cooler Review


Deepcool was founded in 1996 with its headquarters in Beijing with the aim of providing the best customized thermal solutions for customers around the world. When it comes to PC components of enthusiastic grade, Deepcool is a recognized and recognized brand that is gaining more popularity. The company is focused on providing better thermal solutions in the form of air and liquid coolers. Your Captain Ex is a high-end AIO CPU cooler that has shape and function in a single package. Deepcool has seen more success with its Castle and Fryzen CPU coolers and is reaching the insurance trend. The company offers PC chassis, power supplies, case fans, coolers for laptops, PC desktops, lighting solutions. Gamer Storm is the brand of Deepcool under which PC components of enthusiastic level are offered to the market. Tri-Stellar, Quad-Stellar, Genome / II, New Ark 90 are some of their popular and highly customizable PC chassis on the market.

Previously, we had reviewed its premium CPU Cooler Captain 240 Ex RGB and found it at all times. Of a complete cooling solution in terms of performance and aesthetics. Now, the company has launched the next iteration of its famous refrigerator series Captain. Captain 240 Pro is a name of the successor and has three different characteristics in terms of main design. These are: –

  • Addressable RGB LED zones in the block
  • Addressable RGB fans (variant of CF120)
  • Automatic pressure release valve integrated in the radiator

The water block still has a tube of glass that carries refrigerant the lower chamber to the upper chamber therefore, making a path around the Asetek patent. The upper part of the block is where ARGB LED lighting has been implemented. It reminds us of the arc reactor and definitely adds a surprising and daring aspect to the colder and more general construction issue. Now, they have added the second zone in the main frame of the block that extends on all four sides. Unlike the Captain 240 Ex RGB, this cooler has two custom versions of the CF-120 fans. These are addressable RGB fans that have been further optimized for the application of high static pressure and better air flow. The radiator is 27 mm thick with a count of 20 FPI. Since it is compatible with RGB, the Deepcool has included a large number of accessories related to RGB lighting. Another new addition is the 6-port RGB hub to synchronize 6 ARGB devices. Definitely, Deepcool is improving by providing a complete solution at competitive prices. In addition, there is a dedicated controller and two RGB cables that support the integrated lighting solution of all motherboard manufacturers. These are the most outstanding features of the cooler:

  • APAF technology allows Captain Pro to adjust the pressure within the water circulation system automatically and, therefore, ensures stable operation and a long service life.
  • ADD RGB on both optimized pump LEDs and CF fans, which offers users almost unlimited lighting environments.
  • The RGB lighting system can be controlled through the included controller and the specified motherboard. A 6-port RGB hub is included to facilitate RGB synchronization.
  • The dual chamber design in an integrally formed block of water provides greater circulation efficiency.
  • Injection-type micro-water passages allow the copper contact surface to be used completely for heat absorption.
  • The pump driven by a three-phase winding motor provides a continuous driving force.
  • Diamond-quality zirconium ceramic bearings and shaft effectively isolate the operating noise of the water pump, as well as provide a longer service life. 19659005] WS2812B ADD-RGB LED is applied and the 3-pin ADD-RGB headers shown below are compatible for this device: 5V / D / G and 5V / D / NC / G.
  • Item: Captain 240 Pro
  • Manufacturer: DEEPCOOL
  • Brand: Gamer Storm
  • Price: $ 139.99 [at the time of the review]


Packaging and Unpacking [19659030]

The style and theme of the packaging are the same that we saw in his Castle 240 and, lately, they have been following the black / green packing boxes. The refrigerator is shipped inside a cardboard box. The front has the name of the GamerStorm brand and the logo printed on the top left.

Closer look

The Deepcool Captain 240 Pro is a 240 mm CLC cooling solution. It has a 240 mm radiator with two CF120 (custom) 120 mm fans. The size of the radiator is 290 x 120 x 27 mm. The thickness of the radiator is 27mm. With fans of 25 mm, the total thickness would be 52 mm. The radiator has one of 20 fins per inch (FPI). The length of the radiator has increased from 274 mm to 290 mm to provide an automatic pressure release valve. This is what Deepcool is saying about the unit: "Since the birth of the CPU cooler, leaks have been an unavoidable risk for all users. After years of research and development, Deepcool finally got the solution without leaks: the automatic pressure relief radiator. With this patented technology, any pressure within the circulation system will be released to the air, Captain Pro has no reason for leaks. Meanwhile, in Captain Pro, the updated addressable RGB lighting system can be controlled by the included controller or by the specified motherboard. With the included 6-port hub, RGB synchronization is easier than ever! "

The radiator is made of aluminum, therefore, it is lightweight. This is Deepcool's own design. The blocks on both ends of the radiator are rectangular and have straight edges. The stack of fins is dense and, taking into account the left and right side channels, has a total of 12 channels for water flow. You are following the double tunnel configuration. It has a standard entrance and exit blocks for the water flow. There are no protective sheets on the fins under the fan mounts. Therefore, be careful when mounting the fans, since longer screws could damage the fins, which would hinder the performance of the cooler. It is recommended to use the supplied long screws to mount the fans on the radiators.

The rear of the radiator has an identical design in the stack of fins as in the front or top.

Another striking feature is the finishing of the radiator sides. We have a premium touch here. The GamerStorm brand is printed on the Plexiglas and screwed into the radiator with aluminum screws. The final product is amazing in terms of appearance.

Unlike many other AIOs on the market, the hoses are fastened inside clamps of resistant appearance in the radiator, since the tines are hidden inside these clamps.

There is a filling port in the radiator. Surprisingly, it has a Vacuum Guarantee label attached. The recharging port helps users to refill the refrigerant if its level drops and affects the performance of the cooler.

The image above shows the valve or port for automatic pressure release. The Deepcool has named the radiator as an automatic pressure relief radiator. The main concern with AIOs in the minds of users is and has been the fear of flight that could literally fry their expensive systems. The leak could occur due to multiple factors, such as pressure build-up inside the loop that would eventually break through the connection or connection / hose poorly fastened, etc. Deepcool has thought about it and its R & D department took 3 years to find the solution of avoiding leaks due to the internal pressure in the AIO. They have devised the solution in which they have integrated the system of release of pressure in the radiator. It is designed to be part of the radiator that is in the flow of the loop at the exit port. Any pressure inside the loop will find its exit through this valve in the air. Therefore, we have an important concern that is addressed here.

The image above shows the block diagrams of the typical or standard AIO on the right side and the Anti-Leak enabled on the left side. Deepcool has installed a pressure release bag with elastic base on the radiator outlet side. One side of this bag is immersed in the refrigerant, while the other side is exposed to air. When the internal pressure reaches or exceeds atmospheric pressure, the bag will be tightened. This would increase the internal volume of the loop and cause the pressure increase to be released into the air through the valve. This would reduce the risk of leaks in the AIO due to the increase in internal pressure.

The anti-leak AIO is a new concept of its kind and, if proven, is successful. It will be the next big thing in the design of AIO. The pressure relief bag is made of the highest quality EPDM material produced by DuPont with properties such as elasticity, anticorrosion and heat resistance. So far, everything looks good on paper. Only the long-term tests would tell the story, but it is certain that Deepcool has given users where others have not yet done so.

The image above shows some graphs of the Deepcool internal tests where they show The advantages of using a leak-proof cooler during the period when the coolant temperature increases the volume of the circuit, so that leak-proof coolers are more likely to leak due to pressure buildup.

[19659003] There is a sticker attached to the head or radiator chamber. Surprisingly, it even has a voided guarantee if the tag attached is removed. So, we already have four of these stickers. One is stuck in the packing box, three are alone in the radiator.

The hoses are firmly placed in the radiator assembly and in the pump housing. The soft tube is manufactured with an improved anti-explosion rubber tube made of an anti-corrosive material, resistant to crushing and thermosetting. The tube of soft material is a little flexible and does not produce twists, which is always an advantage. Deepcool uses a mesh sleeve on the hoses to give them a clean look. The length of the hoses is approximately 300 mm, which is less than I expected.

Let's see the main element of this cooler. It is the water block with the pump housing. I have seen CLC with a simple design where only the pump is in the block, which reduces the weight of the block and adds more simplicity to the designs. Then, there are tanks integrated in the upper part of the pump housing that not only adds more appearance to the reservoirs enabled for lighting, but also provides a greater coolant capacity. They have what I would like to call the Arc Reactor, since it resembles the reactor, a bomb shell with a unique reactor style that gives the overall look of the block to an incredibly incredible steampunk look. He looks great in person. The dimension of the block is 93.7mm X 93mm X 85mm (L X W X H). The size of the block is relatively higher compared to other CLCs on the market, but definitely, a small footprint compared to the Naia 240 from Reeven and the L240 from Aerocool. The block has a single piece of the diffuser that is cut to the design. It has a solid base of approximately 4-5 mm thick that is visible on all 4 sides of the block, while its upper surface with 22 cutouts protrudes from the top cover. They are circular rounded. The center of the top cover has a glass tube that comes out of it. The overall design immediately shakes your memories about the arc reactor of some kind and Deepcool has designed it to be successful. What's different is that these diffusers have addressable RGB LEDs below to create a lot of amazing looks. This is another area where the design is different from the Captain 240 Ex RGB.

The glass tube is used to bring the coolant from the lower chamber to the upper chamber. This design avoids the Asetek patent. Looking at the block would give you an idea of ​​the design of two cameras.

Looking at what the back of the block should be, we can see the 90 ° barbed fittings that can be somewhat rotating. There are two wires that come out from this side. The upper cable is the LED that measures a length of 275 mm. Believe me, this is a much shorter length than it should have been. It is coming out from the top where the second LED zone is located. We have a solid diffuser that runs the full length of the block housing. The LED cable is flat. The second cable comes from the middle where the real pump is located. It has a nice sleeve and a length of 262 mm.

The left and right sides of the block have the GamerStorm printed in the middle. The mounting bracket or plate is pre-installed and is part of the block. It has two spring loaded screws on each end to secure the block in the mounting assembly. I am a bit skeptical of using only two sides of mounting pressure to install the cooler. Only the tests will confirm if we have any impact on performance or not.

We have a copper base in the block that measures 53x53mm. We have a total of 8 hexagonal screws that secure the copper base to the housing of the block. 53 × 53 is a fairly large size and the base does not have a polished mirror finish. A white protective sheet is glued on the base for the user to remove it before installation.

The Deepcool is using closed impellers driven by a three-phase induction motor to deliver a strong flow of liquid. Deepcool uses zirconia ceramic bearings, which are diamond quality bearings that isolate the noise from the pump and also a longer life. How much longer? It is not mentioned in the specifications or in the literature. Thanks to the double chamber design, the liquid flows in one direction to achieve circulation efficiency. The injection microchannels for water allow maximum use of the copper surface for better heat conduction. The pump speed has a rated power of 2200 ± 10% RPM at 17.3 dB (A) nominal sound level using 12VDC at 0.13A rated current and 1.56W power consumption.

Deepcool has included two CF120 addressable RGB fans with this cooler. These are the improved versions of the original CF120 with specifications adjusted for better radiator performance, as the original CF120s are optimized for the Chassis air flow. I have already done a detailed review of these that can be verified by clicking here. Each fan has 9 translucent blades with dedicated air channels in each blade. There is an adhesive with the logo of the GamerStorm brand in the middle of the fans. Each fan has anti-vibration gray pads in the mounting corners on both sides. The frame has a bright black frame on top. Looking closely, you can see that the main design is circular around the blades and four mounting sides in this circle. The back of the fans has a design almost similar to what we saw in the TF120 fans that we reviewed earlier. There are channels of air formation on the edges of the frame. We have a set of 4 arms that holds and fixes the impellers to the frame. There is a black sticker on the center of the engine with the logo and the name of the GamerStorm brand on top. The fans are made in China. Each fan has 12 RGB LEDs inside the motor hub.

These fans are rated at 12 VDC with a rated current of 0.17 ± 10% A with a power of 2.04W. The fan speed at 12VDC is 500 ± 200 ~ 1800 ± 10% RPM. The maximum air flow at 12VDC is 69.34CFM. The noise level is 17.8-30 dB (A). The maximum static pressure is 2.24mmH₂O. The fans are using the Hydro bearings with MTBF of 40,000 hours. There are two cables per fan. One is a 4-pin power cable with a length of approximately 280 mm and is flat. The second is a 3-pin LED flat cable with a length of approximately 385 mm.

The Deepcool has included a 4-port fan center in the package that is really good on its part. This is a renovated version of the fan center that has an elegant and slim design and looks great in person. The ports are numbered as Fan 1 to Fan 4. GamerStorm is carved on the opposite side of the port numbering side. The other side of the cube has a 3M adhesive tape to easily install the fan in the chassis. The hub has a 4-pin PWM cable that measures 392 mm. They have also included a 4-pin PWM extension cable just in case. That cable has a length of 400mm. If a user wishes to perform push / pull settings on this unit, the 4-port fan concentrator will be useful as it will allow the four fans to connect to this hub and then output a single 4-pin PWM cable. The concentrator can be connected to the fan head of the motherboard to regulate the speed. In this way we can be sure of having the same speed in all the fans. Port one is white to indicate that the PWM signal from this will be used to regulate all connected fans.

RGB lighting

Now, it's time to take a look at the RGB lighting hardware that Deepcool has provided with the unit. The true color 16.7M RGB fluid light system with 5 built-in effects (dynamic, static, breathing, kite and fashion collision) has 36 interchangeable lighting modes in this refrigerator. As we explained above, the addressable RGB LEDs are located in the upper part of the block under the diffuser for which comes a 3-pin cable that leaves the pump housing. Due to the format of this cable, it can not be directly connected to the addressable RGB header of the motherboard. Deepcool has provided two solutions for that. One is the dedicated controller to control addressable RGB lighting effects.

The driver has SATA power. The length of the power cable is 400 mm, while the length of the RGB cable is 370 mm. The controller has 3 buttons at the top. The top button is printed + and used to switch between different lighting modes. It has a lever effect. The middle button is used to control the brightness. It will speed up / decrease the speed of the currently loaded mode and will not work in static mode. The lower button has been printed on it and is used to change the load from the previous mode. There is a warning that I can mention here when it comes to mounting this driver. Ideally, it would be accessible to me, so it should be available outside the chassis, which will definitely be a problem. Alternatively, it can be installed in a place inside the chassis where accessibility can be easy, but for that, we will still have to open the side panel to access the controller.

This is not all, as Deepcool has also included an RGB LED hub that allows you to synchronize up to 5 ARGB devices and coordinate the color. That concentrator can be connected to the controller, either a dedicated one or the lighting header of the motherboard. It has two magnets on the back for easy installation inside the metal chassis. There is also a 3M adhesive in case it is used on a non-metallic surface.

The Deepcool has included an RGB Sync cable that can be connected to accessible RGB headers on modern motherboards such as AURA from Asus, Mystic Lighting from MSI, RGB Fusion from Gigabyte. Two types of RGB LED extension cables that support + 5V / D // G and + 5V / D / G are included to cover each possible lighting solution format on the motherboards. Deepcool is using the ADD-RGB WS2812B LEDs on the CF120 and on the block of this refrigerator. It is clear that Deepcool has not left any corner uncovered. Here is some technical data on LEDs:

Type of LED Addressable
Rated voltage 5V
Rated power 5.7W
LED connector 3pin
LED Control Motherboard with RGB addressable headend / ADD-RGB Controller

Here are some pictures for your visual pleasure and we have made a video about lighting effects.

  Deepcool Captain 240 Pro CPU Liquid Cooler Revision   Deepcool Captain 240 Pro CPU Cooler Review


The cooler has been tested in the Intel LGA2011 (3) and AMD AM4 sockets with Intel i7 6850k and AMD Ryzen 7 2700X. Here are the installation guidelines for both platforms:


  • Install the LGA20XX bolts in the drilled holes around the CPU socket.
  • Place the Intel mounting brackets on these bolts. I would recommend placing them horizontally (looking at the base plate from the standing position).
  • Secure mounting brackets using nuts A (small size nuts).
  • Install the fans in the radiator.
  • Apply the thermal paste to the CPU.
  • Remove the safety label from the cooler base.
  • Place the block on the CPU by aligning the spring loaded screws in the center holes of the mounting bracket and tighten the block in place. the CPU.


  • Remove the AMD serial back plate from the motherboard.
  • Slide the 4 screws on the AMD backplane that came with the refrigerator. AM4 is clearly printed on the holes in the back plate. These screws have hexagonal heads that must fit completely inside the back plate.
  • Place the back plate on the back of the base plate so that the screws pass through the mounting holes.
  • Place nuts B on the screws and secure them to the AMD back plate. Make sure that the black side of the Nuts B is facing the base plate as it has silicone washers.
  • Place the AMD mounting brackets on these screws.
  • Attach the mounting brackets using the Nuts A.
  • Apply the thermal paste to the CPU.
  • Remove the safety label from the cooler base.
  • Place the block on the CPU by aligning the spring screws in the center holes of the mounting bracket and tighten the block on the CPU. .

Common Steps

  • Connect the 3-pin power supply cable of the pump to the CPU fan header or the AIO / water pump header of the motherboard.
  • Connect the fan power cables to the fan hub and connect the PWM cable from the fan hub to the 4-pin fan header on the system board.
  • Connect the RGB LED cables of the fans and the block with the LED concentrator.
  • Connect the LED hub to the source controller.

The installation is complete. One observation I made is that the side of the block where the hoses are located obstructs the installation of the block on the X99, since these hoses can not be completely rotated and were making contact with the RAM. I suppose there's only one way to install the block on the X99.

Test Methodology

We thank our sponsors of the AMD test bench. They are AMD, Corsair, Asus and Antec.

The following software was used for testing and monitoring.

  • Asus Real Bench v 2.44 [Intel]
  • Real Temp GT v 3.70 [Intel]
  • AIDA64 Extreme 5.99 [AMD]

The thermal paste that is being used in my test bench is the thermal paste Noctua NT-H1. The use of the same thermal paste for all coolers will ensure standardization and mitigate any performance benefits that may come with the thermal paste supplied. I also started to test the refrigerators with the thermal paste included. Here is the voltage and clock information for both platforms:

Platform AMD Platform Intel
Clock (MHz) Voltage (V) Clock (MHz) Voltage (V) [19659147] 3700 1.1125 3600 1,130
4100 1.3250 4300


In the values ​​panel of the equipment installations, of the services , services, facilities, services, services, equipment and facilities facilities. to test the CPU. On the AMD platform, RealBench was therefore problematic; I used AIDA64 Extreme for CPU stress tests. Se realiza una ejecución de un mínimo de 30 minutos en cada nivel de reloj y la temperatura promedio se calcula sumando la temperatura del núcleo individual y dividiéndola por 6. La temperatura ambiente se deduce de este valor promedio para obtener la temperatura delta. Esto está en la plataforma de Intel. En la plataforma AMD, tCtl se compensó con -10 ° C según lo recomendado por AMD para el 2700X solamente. AIDA64 Se realizó una carrera extrema de al menos 30 minutos para cada configuración de reloj. Cada ejecución fue seguida por un mínimo de 15 minutos de estado de inactividad. La temperatura delta se calcula restando la temperatura ambiente de la temperatura máxima reportada en AIDA64 Extreme.

Aquí están los resultados.


Veamos los gráficos.

[19659003] En los relojes de stock, el Deepcool Captain 240 Pro se está balanceando en la tercera ranura, aunque técnicamente es el segundo puesto, ya que los dos primeros están con el Asus Ryuo CPU Cooler con stock y pastas térmicas NT-H1. Deepcool claramente está haciendo un caso fuerte aquí.

Con un overclockeado de 6850k a 4.3GHz a 1.350V, el Deepcool Captain 240 Pro ha tomado el tercer lugar dulce nuevamente haciendo su caso más fuerte. Parece que Deepcool ha usado su pasta térmica de primera calidad y también está dando competencia cuello a cuello al Noctua NT-H1.

El Deepcool Captain 240 Pro está sentado detrás del Noctua NH-D15 . La prueba se repitió tres veces para verificar las lecturas tanto en el stock como en los ajustes de overclocking.

De nuevo, estamos viendo al Captain 240 Pro sentado detrás de Noctua NH-D15.

Nivel de sonido

No pude medir el nivel de sonido de la unidad debido a ruidos ambientales no controlables. Según mi experiencia con las pruebas de ventiladores y enfriadores, los ventiladores del enfriador son ruidosos y el nivel de sonido parece estar en los años 30 a toda velocidad, pero no están bromeando. Una curva de ventilador personalizada puede ser útil en caso de que esté sentado demasiado cerca de la PC o sea una persona consciente del sonido como yo.


El Deepcool Captain 240 Pro es una solución de enfriamiento de 240 mm CLC. Tiene un radiador de 240 mm con dos ventiladores CF120 ARGB optimizados para una alta presión estática y un mejor flujo de aire. La dimensión del radiador es de 290 x 120 x 27 mm. la longitud del radiador se ha incrementado para acomodar la válvula automática de liberación de presión integrada directamente en el radiador. El espesor del radiador es de 27mm. Con ventiladores de 25 mm, el grosor total sería de 52 mm. El radiador está hecho de aluminio por lo que es ligero. Este es el propio diseño de Deepcool. El radiador tiene 20 FPI. Hay un espacio de 105 mm entre los dos orificios de montaje del ventilador. El tubo blando está fabricado con un tubo de goma antiexplosivo mejorado fabricado con un material anticorrosivo, resistente al aplastamiento y termoestable. Los tubos de material blando son poco flexibles y no producen retorcimientos, lo que siempre es una ventaja. Deepcool utiliza una manga de malla en las mangueras para darles un aspecto limpio. Una advertencia es la longitud de las mangueras que es de 300 mm. Esperaba un mínimo de 320 mm. Hay un puerto de recarga en el radiador, que para mi sorpresa tiene pegada una etiqueta que anula la garantía. Este enfriador es compatible con los zócalos Intel LGA-20XX / 115x / 775 y los zócalos AM4 / AMx / TR4 de AMD.

Las características distintivas del Captain 240 Pro sobre el Captain 204 Ex RGB son:

  • Sistema automático de liberación de presión [19659005] Ventiladores ARGB CF120
  • Solución de iluminación ARGB en el bloque
  • Modificación en el diseño del bloque para acomodar la iluminación ARGB.
  • Los lados del radiador se terminan con la marca GamerStorm impresa en el plexiglás y se aseguran con tornillos de níquel .

La ​​característica clave de este enfriador es el nuevo sistema Anti-Leak. This is the first of its kind design in the AIOs that we have ever seen and Deepcool’s R&D department took 3 years in the design and testing to finally bring the solution of one of the biggest concerns/fears in the mind of the users when using the AIO; leakage. Using specially designed anti-pressure bag having properties of elastic in nature, resistant to the heat and corrosion and made out of premium EPDM material from DuPont, the DeepCool has integrated this bad inside the radiator on the outlet port. Its one end is dipped in the coolant whereas the other end is exposed to the air. Whenever the internal loop’s pressure buildup reaches and crosses the atmospheric pressure, the bag squeezes causing the increase in the volume of the loop which would release the buildup pressure in the air through the exposed end of the air-pressure bag. Definitely, a brilliant idea with equally good execution though only a long term testing could tell the tale.

This cooler still retains the steampunk, arc reactor design which we saw on the Captain 240 Ex RGB with some modification. There is a glass pipe coming from the middle of the top side and going down the bottom chamber where the pump is located. This design approach has added more to the bold yet sublime looks and it is circumventing the Asetek patent on pump housing design. The RGB LED lighting is implemented on the top side of the block giving the dope look when the unit is powered on. The top section of the housing has a single piece diffuser which is running on the four sides of the housing. The top side of the diffuser protrudes the lid surface. Now we have 22 cutouts on the outer side whereas they were inside in the Captain 240 Ex RGB. The dimension of the block is 93.7x93x85mm.

There are two cables coming out of the pump housing. One is the sleeved 3-pin power cable and the other one is the flat 3-pin RGB cable. The base is made of copper and is polished finish but not mirror like. The base measures the 53x53mm. The back side is where the hoses are implemented in 90-degree rotary position, protruding the block quite a bit. The hoses can be somewhat rotatable not fully. The Deepcool is using the closed impellers driven by three phase induction motor to deliver strong liquid flow. Deepcool is using Zirconia Ceramic bearings which are diamond-quality bearings which isolate the noise from the pump as well a longer lifetime. How much longer? Not mentioned in the specifications or the literature. Thanks to dual chamber design, the liquid flows in one direction to achieve circulation efficiency. Injection type microchannels for the water allows for maximum copper surface utilization for better heat conduction. The Pump speed is rated at 2200±10% RPM at 17.3 dB(A) rated sound level using 12VDC at 0.13A rated current and 1.56W power consumption.

Deepcool has bundled two CF120 addressable RGB fans with this cooler. These are enhanced version of the original CF120s with specs tuned for better performance on the radiator as original CF120s are optimized for chassis airflow. Each fan has 9 translucent blades with dedicated air channels on each blade. There is a GamerStorm brand logo sticker in the middle of the fans. Each fan has anti-vibration gray color pads on the mounting corners on both sides. The frame has a shiny black color frame on the upper side. Looking closely one can see the main design being circular around the blades and four mounting sides on this circle. The backside of the fans has an almost similar design as we saw on the TF120 fans that we reviewed earlier. There are air-forming channels on the edges of the frame. We have 4-arms assembly holding and securing the impellers to the frame. There is a black color sticker on the motor hub with GamerStorm brand logo and name on the top. Fans are made in China. Each fan has 12 RGB LEDs inside the motor hub.

These fans are rated at 12VDC with a rated current of 0.17±10%A with the power of 2.04W. The fan speed at 12VDC is 500±200 ~ 1800±10% RPM. Maximum airflow on 12VDC is 69.34CFM. The noise level is 17.8-30 dB(A). Maximum static pressure is 2.24mmH₂O. The fans are using the Hydro Bearings with MTBF of 40,000 hrs. There are two cables per fan. One is a 4-pin power cable with a length of approximately 280mm and it is flat. The second one is a 3-pin flat LED cable with a length of approximately 385mm. For more information on these fans, please check our detailed review here.

We are not yet done with this cooler as there are many accessories worth mentioning here. Deepcool has revamped its fan hub and has provided sleeker and slim designed 4-port fan hub. It has a 4-pin PWM cable. They have also provided a 4-pin PWM cable extension. The port 1 has a white color base indicating this port’s PWM signal will be used to set the speed of the remaining 3 fans. Instead of providing 3-way LED splitter cable, we have a beautifully designed 5-port LED hub to which we can connect up to 5 ARGB LED devices. They have also provided two LED extension cables that would cover all the LED lighting solution found on the motherboards from various manufacturers. It is clear that Deepcool was on the task when it comes to paying attention to the details.

The Captain 240 Pro is listed at $139.99 at the time of the review. If it seems expensive, let’s recap what is bundled with the cooler. There are two high-performance CF120 fans which have digital LEDs, a dedicated RGB Controller, 5-port LED Hub, 4-port fan hub, PWM extension cable, 2x Extension cables to ensure the complete compatibility with the leading motherboard manufacturers’ onboard lighting solutions, AM4/TR4 compatibility and most above all the mechanism that has been integrated into the radiator to cope with the loops’ internal pressure buildup. Welp, you name it. They have taken care of everything possible that a user would like to do with this cooler. We have tested the cooler on the Intel and AMD platforms and it has performed very well.

We are thankful to Deepcool for giving us the opportunity to review their Captain 240 Pro CPU Cooler.
