Question What is wrong with my CPU

[kubacs]

Yesterday I was playing a game and my computer randomly shut off, I turn it back on and I saw a CPU overheat warning. This kind of scared me and I started to question my aio if it has died (corsair h80i). I start monitoring my CPU temps and turns out, my idling is really weird, I often idle between 40-60 degrees, and spikes of 10 degrees happen quite often, a few times a minute. I have openhardwaremonitor and my max while idling spiked up to 71c.

This happened out of nowhere, and was completely fine for years before, only happened once before but that was when I tried to render a video without gpu acceleration. Anyways, I decided to swap out my AIO cooler thinking as it was dead with the original ryzen wraith cooler, and put new thermal paste on it, and the results have not changed. I still get very high temperatures while idling and gaming, and when gaming earlier today I saw a high spike of 96.3c, which is crazy.

So to date I have completely cleand my case & replaced thermal paste with old aio, no change, then changed cooler back to wraith and again replaced thermal paste, no change.

Is this normal? What could possibly be happening, this is completely out of nowhere.

Ive also attached openhardwaremonitor log which i ran for 30 mins if anyone wants to filter through that and check out my temperatures, this log is purely while idling and afk.

My specs are:

Ryzen 7 3700x
32GB ddr4 3600mhz
B550m mortar
few fans there

Help would be appreciated, thanks.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

(corsair h80i)
Does the radiator dissipate heat or is the tube and the cooling block/pump block the only things that are hot to the touch?

I'd lay good odds that the pump failed in your AIO (they don't last forever)

to be honest didnt think it would matter as my chassis and gpu dont have anything to do with my cpu cooling.

anyways the fan was exhausting and i think it was.

Put back the wraith cooler and temps seem to be kind of improving? theyre still quite high though, often reaching 90 and above when gaming

On the contrary, yes your chassis can help with cooling. Good airflow is essential. What thermal paste did you use when you repasted? What method did you use to apply it?

The 3700x is a 65w CPU, so shouldn't be getting such high idle and gaming temps IMO. Those CPU's have decent efficiency. But, the wraith maybe the issue now. It's just not good at cooling.

10c spikes on Ryzen 3xxx/5xxx are normal, as all cores will boost, hence the spikes. Nothing to worry about there.

It can also be that way too much paste was used (any more than required to fill the microscopic scratches and pits acts as an insulator). Or, paste was reused when mounting a different cooler, thus introducing air (an insulator).
