Hi everyone, appreciate some assistance here. My CPU has hit 100 degrees celcius and shut down. This was happening when the CPU load was 1% with nothing running. I have ran a virus scan (both Defender and Malwarebytes) and nothing there. I have also changed the thermal paste, cleaned the fans and made sure the CPU cooler was secured properly.
This has happened randomly before, then all of a sudden it's running fine again and sits between 40c - 60c for months. It seems to be a completely random event then goes back to normal. It occurs maybe twice a year.
This is what I have:
Gigabyte B650 Gamxing X
MSI GeForce RTX 3060
AMD Ryzen 7 7700X
EK AIO 240 D-RGB
be quiet! Pure Power 11 Gold Modular 750W Power Supply
Anything else I can look for? Appreciate it.
Update: I've ended up applying for warranty for the cooler. I have tried all that has been suggested. For now, I've bought a Noctua NH-U9S cpu fan. If that works, I'll probably just leave it in there.
Thanks again for helping a confused noob girl out. Love this community!
Update 2: I've taken out the AIO cooler and replaced with a fan (Noctua NH-U95). The temperatures are fine now. I was a little worried at first as the temperatures were better but high (70-80c under 10% load). Switched off the PC, now it's back on and it's staying around 43c. It's seems some fresh thermal pastes might take a while to settle in. Thanks again everyone. Never buying water-cooling again.
How quickly after boot up does it happen? I'd almost suspect that the pump isn't running in your AIO.
Less than a minute. I've just read somewhere that I should be able to feel a small hum in the block, I'm going to check for that next.
That's definitely a sign that your CPU isn't cooling. Either your cooling block doesn't have a solid enough thermal connection to your CPU (improper paste, insufficient pressure, etc), or the fan for the block isn't coming on. Does the CPU fan spin up? Does the fan speed recover after the fan is physically stopped?
