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.
What’s your cooling paste situation like? Too much? Too little? Bubbles? I’m sure a picture would reveal an issue.
The other side
This is what when cooling paste looks like after I’ve taken it off. This first PC I’ve built, so still learning.
Did you remove the heatsink and replace it again without changing the paste? I don’t think its a good idea - try reapplying thermal paste whenever you remove the heatsink. Clean the old paste off first
Nah I reapplied it again. Every time I take it off I clean it and do it again.
Amount looks fine. Maybe a bit in the “much” side, but not to the point where it’d cause this issue.
After the PC shuts off due to temp, does the cooling block feel hot to touch? If so, that means that the heat is transferred away from the CPU (good), but not away from the cooler (not good).
I’m not very good at liquid cooling systems, so I’ll defer to others for help with troubleshooting that.
What’s going on here:
If your CPU isn’t under load and it’s heating up I’m guessing something may be shorted out. Maybe remove the CPU and carefully inspect the socket and chip??? Be extra careful with the CPU socket I think it’s one that is really easy to damage.
If there was a short on something, the CPU wouldn’t work.
Even at idle, CPUs generate heat because there’s electricity flowing across them. That heat needs to be dissipated and for some reason, it isn’t.
My bet is either a pump failure, or power loss to the pump. Looking at the thermas paste marks on both the water block and the CPU, it looks like it’s making at least decent contact. If the water was flowing through it, it shouldn’t be overheating at idle. It might not be performing at peak efficiency, but it shouldn’t be overheating.
Most thermal paste isn’t electrically conductive, so that blob inbetween the capacitors shouldn’t be an issue, but it would be good to know what thermal paste it is to be sure.
