Hi,

So recently I have been encountering a problem.
Basicly my cpu keeps thermal throttling but only under Linux.

I have a I5-9600k and a Nzxt Kraken as a AIO
Im on Kubuntu 21.04
To stress my cpu im using s-tui with the defaults settings.
Basicly as soon as I start stressing my cpu goes up to its max core frew which I overclocked to 5GHz but then goes back down after maybe 10 seconds of being stresses. The same behavior does not happen in windows. In windows im using cinebench R20 to stress test and my cpu stays around 80C.
Even if I set my AIO fans to 100% with liquidctl my cpu has the same behavior and I cannot for the life of me figure out why.

If anyone has any idea im open because this is getting annoying.
