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.

    I'd like to see a review. If they say it can cool 125w, then I believe them, but I don't see how a coating alone will improve cooling. There must be more to it.

    A graphene-coated insulated cooler won't change anything.

    It is already available in stock in europe at roughly 75 eur tax included.

    I had very high hopes for this company, I truly did, sadly they another company who lost touch with the "how should be being done"

    sorry, but how many company we truly need that offer a slight thinner slight higher than "ok" performance IN THE REAL WORLD for in the $90+ range.....

    screw that IMO....maybe try ensuring your product are not listed far far far higher than MSRP suggest should be on H7 list for under $45, but more oft than not (when could find) was priced ABOVE far far higher performance product...their answer "we cannot control third party price listing"

    sure you can, one call to lawyer and a CEASE DESIST given...ahh well, they must make lots of $$$ to be the same as A $%$ other companies doing lately, last one they released was H7 RGB one (from what recall) was WORSE performance but HIGHER price (far more complaint of NOT mount proper) ...I guess their answer was "oh they want CU based coolers that are even higher priced and a shorter cooler that is priced as high if not higher than liquid that trashes anything we are able to list for $60 or less...ahh well, lst us take $2 cooler and charge $90+


    that is what I see from Logitech, Razer, these folks, Corsair, Cooler "baster" rinse an old product, slap even higher price on....

    blekk..utter blekk

    Nope. I saw somewhere that graphene coating adds 1-3% improvement

    well for fast cpu's to blossom there needs to be new tech to cool these future heat producing cpus

    Marketing BS.

    Can Anandtech please not to help fraudsters with their obvious frauds? Anton, if you don't understand why this is fraud, ask Ian.
