I'm on kernel 5.4.26, manjaro I3 and I'm experiencing some freezes when I'm installing games or extracting large zip files with a 8600k, to the point that I can't browse any file manager or the internet comfortably when doing so. On the other hand, I have absolutely no problems when playing games.
I've enabled the turbo boost in the bios but I think that I was having the same issue when it was not activated. It shouldn't be a cooling issue since I have a very good air cooler.
I feel like it's not normal but I might be wrong.
Let me know if you need any more information, I'd be glad to give them ! I may only be able to answer in a few hours though.
Thank you very much for your help !
