I have a Dell Optiplex 3060 here, that I used as a backup desktop with Linux, but now I’m trying to use it essentially as a streaming host for games (Fallout, GTA…), unfortunately that means Windows.
And even less fortunate: Windows seems to think, fan speeds only know one direction: up.
Essentially, the machine starts nice and reasonably quite, but after some load (e.g. a game), the fans never spin down again. Even if the temps are fine (all cores at <30°C, GPU at 48°C), it keeps running in turbine mode.
The only “fix” is a sleep or power cycle.
Since this machine is supposed to run relatively long hours and sit in my room, this is quite annoying and I’m kind of out of ideas.
Newest BIOS and all the Dell Magic™ are installed.
I had an optiplex like this. I would give the top of the case a couple taps and fans would spin down. No idea why that worked but it did it every time, hurricane winds, couple good taps to calm it back down
