Question Shutting down from overheating but reading normal temperatures

[elevatorcait]

I have a ryzen 5 5600g with stock cooling. It's not the greatest cooling solution in the world but it's worked fine for the last two years. For the last couple days though, my computer will be working like normal for hours and then suddenly the CPU fan starts spinning really fast and then the computer shuts down and says it was a thermal event. I've kept NZXT cam open to watch the temperatures to see if they spike but they don't even seem to go up when this happens, it's sitting at around 50-60c. I had changed the XMP profile in the bios so my RAM would run at 3600MT right before this started happening, but I undid this change and even reset my bios to default settings and it's still doing this.

Run Hwinfo64 instead, NZXT is known not to be accurate.

Have you checked to see if the cooler is still firmly screwed down?

Is it this version?

HWInfo seems to be reading the same temperatures as NZXT was. I'm just not really understanding why it would run at a normal temperature for hours and then suddenly within 5 seconds get so hot it shuts down

What about frequency though, is it the same or is it thermal throttling? Run a cpu stress test like cpuz and watch speed vs temps.

I ran the cpuz stress test for about 10 minutes, it seemed to stabilize around 85c and 4ghz. It never went under base clock of 3.9ghz. It seemed to be doing fine and I stopped the test, and about 5 minutes later the fan spun up and shut down the computer while it was reading about 70c

I ordered some thermal paste and I'm going to reapply it once that comes since it never hurts to do that anyways, I'm hoping that solves it but it still seems weird that it's shutting down while reading lower temperatures especially since this has never been an issue before

I don't think it's thermal throttling then but probably hitting a limit set in bios. Have a look in there to do with pbo, raise the thermal limit to 90c.

Did your stock cooler come with pre-applied thermal paste? If so, I doubt your problem is due to too little (or too much) TIM. I suppose it's possible the compound has dried out after two years.

I'm guessing the temperatures you're monitoring are "average" readings, not "peak". The system may shut down suddenly, if the CPU is stressed really hard and the cores hit "shut down" temperature. I've no idea what's causing the sudden burst of activity and shutdown.

If new TIM or a bigger cooler don't fix the problem, it might be an idea to try another CPU - cheaper than buying a new motherboard.

Update your post to include full system hardware specs and OS information.

PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full, how connected)?

Look in Reliability History/Monitor for any error codes, warnings, or even informational events that may have been captured just before or at the times of the unexplained speed ups and shutdowns. Look for patterns in the Days/Weeks timeline.

You can also look in Event Viewer - just takes more time and effort to navigate and understand.
