Cryorig has introduced its low-profile CPU cooling system for small form-factor PCs that can dissipate up to 125 W. Featuring a 47-mm z-height and a 97-mm depth/width, the Cryorig C7 G is among the smallest coolers for higher-end processors available today. To make C7 G's high performance possible, Cryorig had to apply graphene coating on the heatsink.

As owners of SFF PCs demand higher-performance components, cooling designers are creating low-profile coolers rated for TDP levels of 95 W of higher. To maximize efficiency of such devices, manufacturers use copper for heatsinks, many heat pipes, and large fans. Cryorig decided to go one step further and applied graphene coating to the radiator’s fins. Thermal conductivity of graphene is in the range of 3000 - 5000 W/mK at room temperature (according to Graphene-Info), which is considerably higher than thermal conductivity of aluminum (250 W/mK at 25ºC) or copper (401 W/mK at 25ºC), so applying it on the fins could theoretically improve cooling performance.

Just like regular Cryorig’s C7, the model C7 G features four 6-mm heat pipes and a 97-mm PWM fan with 11 curved blades that rotates at a speed of 600 – 2500 RPM producing airflow of up to 40.5 CFM as well as rated for a maximum load noise level of 30 dB(A).

As far as compatibility is concerned, the Cryorig C7 G cooling system can work with all modern platforms from AMD and Intel, including the latest AM4 and LGA1155 sockets.

Cryorig’s C7 G cooler will be available in Japan starting September 28 for ¥9,960 without sales tax ($92.50), which is certainly higher than average for an air cooler. Evidently, graphene coating is expensive and dissipating up to 125 W using a cooling system featuring a 47 mm z-height is a unique capability, so the price can be justified. The unit is already listed on the company’s website, so its launch in other countries is imminent.
