So today I found about the fact that AMD GPUs should be undervolted in many cases. I had the problem that my card got very hot and thus extremely loud.
I have the RX 7800 XT since April 2025.
I am playing on QHD and the best settings for games like Oblivion remastered, valheim, enshrouded etc. Especially enshrouded made my card extremely hot.
Hotspot temp was around 95 to 100 °C
Global temp was 80 °C
So I undervolted that b a little. Voltage down from 1150 mv to 1050 mv and max frequency also down a little (100ish).
Result? 15 °C (!!!) less hotspot heat. Global temp went also down. New temps under same circumstances as above:
Hotspot 85°C
Global 70°C
Fans very silent.
And the best thing is, not even performance losses. Same FPS.
So yeah, if you have the same problems as me, just try undervolting.
Thanks for reading.
