[SOLVED] CPU randomly overheats

[Gavin Crane PC]

At random times throughout the day, my 3700x will spike to 90+ C causing a system shut down while doing light tasks, gaming or even idling. When using stress tests such as prime 95 it peaks at 70-75C. I am using a 240mm AIO which I think may be the culprit, but I don't have another cooler to test with. I have re-applied thermal paste and locked voltages to 1.3 volts for the CPU. I haven't overclocked it at all.

Any ideas? Is my pump just crapping itself randomly? Thanks in advance.

Latest BIOS version for your motherbaord? I would look into a donor/replacement PSU to rule out the Vengeance being incapable of powering the system when taxed.

Case?

My case is the h500. I know it isn't the best in terms of airflow but I have 4 fans (2 intake 2 exhaust). I'm curious about the PSU not being able to power the system when taxed. Is that a thing I should worry about? I mean its 650w which I think is enough for a 3700x and the rest of my setup. I'll try updating bios in the meantime

Well form what I know with liquid cooling your CPU shouldn't even reach 70C in overclocking so you're probably right. So try it with a simple fan and see how that goes
