I recently bought Scythe Fuma revb inorder to oc my ryzen 2600x to 4.1ghz/4.2ghz . I managed to get 4.1ghz at 1.3125 vcore. Running prime95 with small fft 1344k(min-max) for 30 min gives me an average of 74.4ºC (tctl/tdie) and a maximum of 81.8ºC. Are these temp okay and my cooler doing well or not???
