Cryorig C7 G Is A 47mm Low-Profile Cooler with a Graphene Coating, Rated for 125Wby Anton Shilov on September 26, 2019 3:00 PM EST

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.

Kilnk - Sunday, November 10, 2019 - linkThis is too thick for laptops. This is meant to be used in small form factor cases such as the Dan Case.
Jorgp2 - Friday, September 27, 2019 - linkA black coated surface will release heat better than a shiny metal one.
That doesn't change the fact that this cooler is shit though, they're just rehashing it to save tooling on releasing an actual new product.
peevee - Tuesday, October 1, 2019 - linkIn a CPU cooler heat release by radiation is insignificant compared to direct contact with air. For example, the fins will radiate the heat right into the fins next to them, so even fins do not make sense for heat release by radiation.
Besides, black also accepts external radiation better.
Kilnk - Sunday, November 10, 2019 - linkThis cooler is the best performance cooler for its size. This is meant to be used in small form factor cases with low clearance. When you don't know what you're talking about, don't.
Kilnk - Sunday, November 10, 2019 - linkI will add that this cooler can comfortably cool a stock 3900x. It's far from being shit.
Kilnk - Sunday, November 10, 2019 - linkOptimum Tech has compared the C7 cu with the C7G and there is no difference in thermal performance. However, the C7G won't oxidize while the C7 cu will with time thus the C7 cu will lose performance while the C7G won't.
jtd871 - Thursday, September 26, 2019 - linkExpect to pay extra for this in NAMER as Cryorig has apparently abandoned North American marketplaces. 3rd party sellers on Amazon are currently charging $135 for the basic C7 (I bought one in 2017 for $30), which is a nice markup even on an import.
Operandi - Thursday, September 26, 2019 - linkThis has already been tested by NotFromConcentrate; the graphene coating does nothing to improve the performance of the heatsink.
From what I remember of the video the science behind theory is sound but the application of the graphene is not done properly and in the level of precision that would aid in improving thermal performance.
Stick with Noctua if you want the best performing low profile heatsink.
