Dune Awakening. I normally don't like these kinds of games but I'm a big Dune head and although it needs to break lore for thr sake of fun, the aesthetics are all there. I'm about to build a body juicer to uo my supply of water.
Like all games in this genre though, it runs like garbage and its kinds frustrating to go from butter smooth gameplay to 20 FPS stuttering in the middle of a gun fight or when trying to outrun a worm.
Is it only one? And is that one plugged into the CPU Pump slot? Fans in that slot usually run at 100% constantly unless set to PWM mode in the BIOS and after that, can still do it momentarily before your BIOS or any fan control software you're using tells it to calm down.
Might not be that, but I've seen it several times.
