I was doing some work on my mac mini (replacing thermal compound), so I got it put back together and went to power it up and the first thing I noticed was that as soon as I plugged in the power cord (didn’t even press the power button yet), the fan instantly jumped to 100% and the machine would not boot upon pressing the power button, showed no indication that it tried to boot either. No display output, CPU heatsink was room temperature after keeping it plugged in for about a minute or so.
I tried searching online and couldn’t find anything related to this, the closest thing I could find was the CPU fan jumping to 100% after the machine started to boot. I’m worried I might have killed it somehow (couldn’t have been static since I had an anti-static wrist strap on and confirmed I was grounded)
