I just bought a used comp and I am having issues with the CPU overheating. The guy who sold it to me had it run for a good 15 minutes and it was really quiet and had no issues. When I got home I unplugged it all, cleaned evert part of it, and put it back together. On the first startup I immediately noticed that there my CPU cooler was making tons of noise. I noticed that in my BIOS, only my CPU fan was showing (at 2.2k RPM) compared to all fans showing when I tested it over at his place.
Here is what I have: 8700k Z370-E Rog Strix H100i V2 Corsair 750T case As for the rest it probably doesn't matter.
All my other fans turn but as I said don't show up in bios.
My CPU is at 60-90 degrees while doing nothing.
As I said, it was normally working until I unplugged, cleaned, and replugged. The wires coming from my CPU cooler (3 of them) are plugged this way:
The 2 that are together plug into the fans which are attached to the "big" piece.
The single wire is attached to the CPU fan slot on the motherboard.
The last one was put into the USB 2.0 slot.
When reading online many people mention the pump failing. I am unsure how to check this and would be surprised as it was working fine before. When I cleaned the computer I made sure to be careful and only used air pumps and wipes to clean the fans which i detached first.
I did not re-apply thermal paste, so perhaps I should do that, but then again would this cause it to fail so suddenly?
