[SOLVED] Sudden increase in CPU temp

[omizdea]

Hi *,

As of yesterday, my CPU temp started to rise towards 100 C point usually constantly being between 90-100 C w/o any reason.

I haven't played around with the hardware/BIOS settings or added new hardware or software for what's worthwhile and I am not overclocking and haven't ever overclocked this system. If I look at the metrics in BIOS the core/socket is between 45-50 C, after Windoze starts they reach 100 C in 15-20 seconds.

I tried everything to diagnose the issue: there aren't any CPU resources draining processes, I even the thermal paste even when there was no sign of uneven distribution on the CPU copper piece of the AIO liquid cooler (I have an MSI MAG CORELIQUID 360R AIO CPU Liquid Cooler), checked and cleaned all the fans and they seem to be ok, updated BIOS, turned Intel Turbo off as well but still no luck.

I'm running on an MSI MPG Z490 GAMING CARBON WIFI(MS-7C73) and the CPU is an i9-10850k.

A few years ago I had another similar issue on a different system with Hyper-V adding a NIC that default configuration made the CPU crazy and it wasn't caught by process monitors or HWMON, but that is not the case now.

Please see attached. Please disregard the spike at the end. It is associated with doing a bandwidth test running on 1 Gbps

Any ideas?

Is this the first one? If so, you might want to read through this;

If you have warranty on the cooler, best RMA it and not undergo troubleshooting since it looks like a pump failure to me, unless you can remove the AIO, have the pump dangling below the radiator and shaking the pump to rid it of any airlocks/cavitation.

Adding to some of the above, if you had the radiator installed in the roof of your case for an extended period of time, the pump would be running dry after some permeation has occurred, as well as every time you power on the PC.

have the pump dangling below the radiator

The pump is embedded in the radiator on that model though...

Here is an example of the temperatures I get while my 10850K is running Cinebench at full loaded. Cooler is a 240mm Corsair H100i RGB PRO XT. It can easily dissipate 171W of heat.

Your MSI cooler either fell off or it is defective and needs to be replaced.

Thanks everyone for helping out. I think it's worthwhile mentioning that I rarely power off my PC, but anywho I ordered a replacement.

Thank you all, the AOI replacement did the trick.
