It's a "fiddling with your computer" kind of day today.
Re-applied the thermal paste on my CPU, because I thought I might be getting thermal throttled.
Now playing the game of "what's the right fan speed curve that cools but isn't too loud". Probably made worse by not being used to newer Ryzen processors that run hotter!
Also, the PC is still on my desk, so I'm probably getting a false impression.
