Cryorig M9i CPU Cooler Review


Cryorig was founded in 2013. They are a relatively new brand and took a while to create, but they are recovering faster than ever and their products are receiving a great reception and appreciation. It is about making the best possible gear. Let me add a bit by saying that a cooling platform with style is possible. That's right. Their refrigerators have nothing to do with a typical industrial design, but they are different not in terms of design but also in the overall aesthetics and attractiveness of the products. Its refrigerators like H7 and R1 Universal are very popular among budget users and enthusiasts respectively. They are also producing CVX although I still have to review them. Previously, he had reviewed his R1 Ultimate and, as the name implies, is the best in thermal performance and fair in terms of money.

Today, I'll be looking at your entry-level CPU processor, the M9. This refrigerator comes in two configurations. M9i is for the Intel-only platform, while M9a is for the AMD-only platform. The sample that I have is M9i. The M9i is a single tower 120mm slim profile heat sink, which features a Jet Fin acceleration design for better and faster cooling, pure copper base and infinite RAM compatibility. The cooler has a height of only 124.6 mm, which makes it almost universally compatible with most PC chassis that exist in the market. How will it work and can it soothe the nerves of Intel's active chip aka 7700k? Let's find out

Nearest Features

The Cryorig M9 is an entry-level CPU cooler still designed for efficiency and performance. The M9 features the Jet End acceleration patented by Cryorig and a 120 mm PWM fan for a highly efficient and compatible package. It is a 120 mm heat sink and a single tower with a height of 124.6 mm, which allows it to be installed in most PC chassis on the market. Let's take a closer look at the cooler.

The cooler has the dimensions of 87 mm x 102 mm x 124.6 mm (L x W x H). This refrigerator has a thin profile. The upper side of the cooler is what sets it apart from the rest of the competition. Unlike the typical industrial design, where the heat pipes are terminated from the upper fin, there is a black plastic cover, which covers the maximum of the upper side. This plate does not cover a certain part of the rear part of the upper refrigerator. This gives the cooler a unique black / silver appearance.

A detailed inspection would reveal that it has angled openings on both sides implemented in the opposite direction from each other. This is to ensure adequate air flow even from the top. The Cryorig brand is engraved in black in the center of the plate. The black color adds to the neutrality of the appearance and allows the cooler to be used on any color theme.

The front side has a 120 mm fan pre-installed with metal clips. Removing the fan reveals the front side fins of the cooler. There are 40 fins stacked together. If you looked closely, it would be evident that there are two layers of fins running in parallel with each other. The plate of the upper fin has more start than the second plate that is inserted and this pattern is repeated until the end. This is known as the structure of alternating fin piles. Another interesting observation is that the space between the two fins on the right and left sides of the cooler is 1.6 mm, while the space between them in the front is 3.6 mm.

This design allows a combination of Jet Fin ™ Acceleration. The idea behind this design is to use a larger and wider air inlet and a narrower exhaust air section in the fins, which compresses the air so that it moves faster when exiting the heat sink.

Air leaves the system more quickly and efficiently, allowing for better cooling performance. The fins are made of aluminum. The back of the cooler has 40 fins stacked in the narrow configuration. The fins are made of aluminum. There are cutouts on the end sides of the stack of fins on the back.

The left and right sides of the heat sink have a symmetrical design.

This refrigerator has 3 heat tubes of 6 mm each. They are soldered with nickel in the heatsink and in the base of the refrigerator. Looking closely would reveal that the heat pipes are entering the heat sink more from the front than from the back side. There is a gap of approx. 1.1 mm from the last tube and the stack of rear side wings. There is a gap of 0.7 mm between the first tube and the front side of the fin stack. This is the area that is also being covered by the top plate.

This refrigerator has a copper base plate measuring 33mm x 39mm x 0.6mm. The heat pipes are welded on the copper base. The copper base has a large block mounted on top of it with two screws that are used to secure the cooler on the mounting bars. There is a security sticker stuck on the refrigerator that reminds the user to remove it before installing it.

This refrigerator has a compensation design very similar to the one we saw in the Cryorig H7. This approach results in maximum compatibility for RAM. As the cooler is not compatible with the Intel LGA-2011 socket (3), we have infinite RAM compatibility.

The Cryorig has supplied a 120 mm fan with the cooler. The dimensions of the fan are 120 mm x 120 mm x 25.4 mm. With a weight of 80 g, it has a nominal speed of 630 ~ 2200 RPM with noise levels of 26.4 dBA and 48.4 CFM of air flow. The nominal air pressure is 3.1 mmH2O. It takes 0.11Amps with DC 12V. It has a 4-pin PWM connector. The cable is braided in the black sheath and has a length of approx. 320 mm including the connector.

The fan frame is black. The blades are black as well. There are 7 blades on the fan. The central axis is a pretty Cryorig sticker stuck with edges in different colors and the Cryorig logo in the middle. The mounting locations of the fan at all four corners have no rubber padding. The air flow and the directions of rotation of the fan are indicated by the arrow marks on the side of the frame.

The back of the fan shows the 4-arm structure that supports the fan blades. This structure is incorporated in the fan frame. The maximum fan speed in terms of RPM is printed on top. The address of the Cryorig website is printed on the bottom.


The installation of the Cryorig M9i is simple and straightforward. The motherboard that I am using in my second test bench is the Asus Z170-P that works with the Intel i7 7700k.

The first thing in the installation is to pass the long screws through the central holes of the back plate in each of the four corners. This hole is labeled B and is designed for the LGA 115x socket. Consult the user manual for more details. The back plate should be placed on the back of the motherboard so that the Intel side is facing up. Make sure that the hexagonal heads of the screws are inside the edge of the frame of the back plate.

Next, place the two mounting bars on top of the screws on the front of the motherboard. Decide your position of placement according to the desired orientation of the cooler. Use the metal nuts to screw the mounting bars into the long screws. Do not worry if there is bending between the back plate and the mounting bars, since once the cooler is installed, there will be no bending.

Next, apply the thermal paste and place the cooler on top of the HIS CPU in such a way that the two screws on the base block of the cooler are aligned with the screw holder on the mounting bars. Connect the fan to the cooler and connect the 4-pin PWM connector to the CPU fan header or any fan header you choose. This cooler can be used in the Push / Pull configuration for which Cryorig provides an additional set of fan clips.

Compatibility and game

When it comes to air coolers, we need to ensure compatibility with respect to the Chassis, RAM and the first PCIe rail. With only 124.6 mm in height, the Cryorig M9 has a high level of compatibility for most PC chassis on the market. Not only that, but the implementation of the offset design has made this refrigerator have infinite RAM compatibility. Nor did I see any incompatibility with respect to the first PCIe lane.

Test Bench

The following test bench was used to test the cooler:

  • Intel i7 7700k [Thanks to the PCFanatics]
  • Asus Z170-P [Thanks to the PCFanatics] [19659020] Corsair 2x8GB Vengeance LED red @ 2666MHz
  • HyperX 120GB SSD
  • Thermaltake TP DPS RGB 750W PSU

Asus Realbench 2.44 and the image The stress test and the monitoring of the temperature. Noctua NT-H1 thermal paste is used to test all refrigerators on my test benches. This helps ensure standardization and reduce the effect of any grouped thermal paste that could benefit performance.


First, the cooler is tested on the clocks of values, that is, 4.2GHz in the manual 1.16V Vcore. The average of the central temperatures is calculated to provide the temperatures at rest and under the load. The ambient temperatures are subtracted from these temperature readings to give the delta temperatures. My graphs report delta temperatures. This helps in an uncontrolled environment to mitigate temperature variation.

Next, the CPU is overclocked at 4.7 GHz using the 1.22V VCore manual. Three runs of the stress test program are carried out. Each 60 minutes long with 15 minutes of idle time in between. The average of each run is taken separately and the highest reading of the three tests is used. The ambient temperatures are subtracted from the selected average temperature reading and the delta temperature is indicated in the graph.

Let's see the results.


In clocks of values, that is, 4.2GHz [fixed] the maximum temperature of the Cryorig M9i was 45C [delta temp]. The maximum temperature in the Raijintek Lito was 46C [delta temp].

The CPU was overclocked at 4.7GHz. The maximum temperature of the Cryorig M9i was 57.25 ° C, while the maximum temperature of the Raijintek Lito was 58.55 ° C. Honestly speaking, I would not blame the refrigerators if the temperatures are higher, since the chip I have It has a bad temperature. Even my Noctua NH-D15 has struggled to keep its high temperatures at bay from that perspective; This budget cooler has worked quite well.

I did not measure the acoustic performance using the sound meter due to environmental noises that are out of control. But, based on my experience with the fan tests, I had a pleasant experience during the testing session.


The Cyorig M9 is a compact design compact 120 mm thin profile compact air cooler with maximum compatibility built throughout the refrigerator. The cooler has the dimensions of L87 x W102 x H124.6mm with only 345 g of weight. The cooler has three heat tubes of 6 mm each and are nickel-plated. The base is C1100 pure copper in nickel plating. The nominal TDP of the chiller is 120 watts, so it is definitely capable of handling the hot chips.

The Cryorig has used its patented Jet End acceleration design in this cooler with the simple concept of having a wider air inlet and a narrower exhaust that would allow hot air to leave the cooler faster and better. We have 40 nickel-plated fins. The front side wings are implemented in an alternative stack configuration with a 3.6 mm space between the fins. There is a gap of 1.6 mm between the fins on the sides or in the center of the center of the cooler. The cooler has a compensation design to ensure maximum space and compatibility. Practically, there is no incompatibility of this cooler with respect to any high profile RAM and from the first PCIe rail. Even the height of 124.6 mm has given this cooler almost universal compatibility with the PC chassis.

The Cyrorig has provided a 120mm fan that has an RPM rating of up to 2200, the noise level of up to 26.4dBA and 48.4 CFM. The fan is well equipped to handle the job. Draw 0.11Amps with 12V DC. The cooler has a 3 year extended Cyrorig warranty.

Let's conclude.
