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.
You can stream using Sunlight (server) and Moonlight (client) on linux. What specifically are you trying to stream as it's likely Linux will be able to play them.

Here's what could help with your fans on boot. However that's a tiny machine and you might want to get a different impeller

Linux is not an option. I tried, see my other comment.
Then you might be interested in the last link I shared in my post.
Tried that. It found one fan, and that's the GPU fan - which spins down just fine, so no gain here.
