[SOLVED] CPU overheating while idling

[hjrisdabest]

Cpu: i5 8600k @3.6 ghz
Motherboard: asus z370 p 1151
Gpu: gtx 1050 ti
Fan : Corsair H45 Aio

It started when I was installing new mouse and my pc crashed due to cpu over temperature error. I reset cmos to get it to boot and then noticed 70-95° C temp even when almost no programs were running . Cpu frequency jumps from 0.8ghz to 4.2 ghz ( I havent overclocked ever) the usage stays around 5-6%

I have tried: 1)Cleaning components to remove dust . 2) Scanning in malwarebytes (Results shows Clean) . 3) Removing cpu and reapplying thermal paste 4) Uninstalling any unnecessary softwares
I have checked the Aio pump and fan it seems to be working as before . I used to get around 67° C max when gaming
I have searched many threads but no solution worked for me . Any suggestions are really appreciated

I'd suspect that either the AIO cooler is gunked up and needs replacing. Or the AIO isn't torqued down properly.
I would suggest trying to retorque the cooler. How old is your cooler?

I affixed the cooler just the other day and it doesnt seem wobbly and is firm in contact with the cpu , how can I troublecheck it for the problems you mentioned ?
The cooler is 2 years old .

There may be guides on how to troubleshoot your particular cooler. I would suggest removing the cooler and inspecting the mounting area for misalignment or damage.

Its possible that you may be able to remove the cover from the IHS and inspect it for clogging once you remove it from the PC. There may also be a drainage port or something similar where you can refill it. I would google your cooler and look for guides on disassembly and troubleshooting.

No problem, hope you find out what the issue is

Your AIO may be clogged up, keeping the fluid from circulating.
Normally, you can feel the pump operating if you touch it.
After 2 years, I imagine it is no longer is under warranty.

A H45 is not a particularly effective cooler.
A single 120mm radiator does not have sufficient cooling surface to let you get the max out of your 8600K.

What is your case?
If you have 160mm available for a cooler, I would suggest a twin tower air cooler.
I use a noctua NH-D15s with a 8600K@5.0.
A simple CPU-Z stress test maxes out at 65c.

Corsair H45 is inadequate cooling solution for 8600K. You need at least 220/240mm AIO liquid CPU cooler.

Okay thank you guys for your suggestions , I will try to get a newer AIO 😁

If your case is suitable, you might be better off with an air cooler.
They will be just as effective, be cheaper, quieter, be more reliable, and will not leak.
It is only when you get into the 360 size aio coolers that you can do substantially better from a cooling point of view.

I have a Corsair h60 120mm on my i5-9600K and it cools very well. Today my temps have ranged between 21 at idle and 57 when playing BF5 multiplayer on Ultra settings.
