Hey. So some days ago I just took my water cooling out, refilled it, put some fresh new thermal paste, as I do every 6 months. So it booted normally, got a bit cooler operation etc. So suddently after about 8 days (today) I went into windows, and just were browsing a bit and then from nowhere my aio water cooling fans went to 100%, and I went into task manager and looked and cpu utilization was 2 %, so I went into a thermal monitor program, and saw that the tempratures were peaking at a wooping 90 - 100 degrees celius, so I got worried, shut my pc down. Then I went into bios, and it was maxing the fans there and going at 90 degrees, but one thing I noticed was that normally when I start my pc I hear a little sound from my pump, but now I didn't. So I plugged my PSU out, left it without power for 10 mins, plugged it in, and pump made sound, temps were back to normal and are now as I am writing this. What is happening?
