Purchased for an R9 5950X

Install was straight forward and very happy with performance.
Haven't seen temps rise beyond 65 deg in a 21 deg ambient room while running Prime 95 for 30 min.
Noise levels are surprising too. Fan set to 100% makes less noise than my toaster so I have it running maxed all the time.

Superb Cooling and Aesthetic as well

Fitted this on my B650 Gigabyte Gaming AX and Ryzen 7900. Just need to take note of the ram, need to adjust it to A2 B2 slot and a sort of low profile ram do the trick. Using the Kingston fury beast 6000mhz DDR5
It cools my Ryzen 7900 at 41-45 degrees at idle and goes up to 61 degrees max on gaming. "Pretty low temps for Ryzen 7000 series
