CPU: Ryzen 9 3950X, stock
GPU: 3090FE, UV to 1650@737mV (yes, there is a small performance hit with this setting)
MB: Asus B550-I
Rad+Fans: Magicool G2 Slim 360 with 3x Phanteks T30
Ambient temp: I don't know, outside it's 25C, I guess it's around 20 in my room...
Fan RPM: 520 (they can go lower but I always want at least some airflow)
LOAD temps (10min Cinebench loop + Unigine Heaven):
CPU: 74 (package power 144W)
GPU: Core 57, Hotspot 69, Memory 76 (with UV, max power draw is 250W)
Fan RPM: I've applied a curve based on coolant temp, the max RPM reached during test was 1070, keeping the coolant at 43C
Overall I'm really happy with the temperatures. But I don't know if they are good
Especially with the low noise the system makes I can't complain. Sometimes, the loudest parts are the pump and the bad coil whine of the 3090.
