Hi All

Just joined to ask for some help.

I have a PC that I use simply for autocad and autocad revit for architecture and 3d modelling.

My PC CPU just keep on overheating (if its sits on 80 degrees plus it will close down as a failsafe). I even have a fan just for my PC to keep it cool but even that doesnt help at all. (general resting temp when nothing is running is around 50 - 60 degrees)

I have tried removing the cpu cooler to see if thats working and it is. I have reapplied new thermal paste which didnt help as it still keeps overheating.

Does anyone have any other ideas before I have to take it to a PC shop?

Any help is appreciated.

Thanks
 
What steps have you taken so far? You said you removed the cooler, but anything else? Have you cleaned all the dust out?
Do you know what CPU it is and what cooler? Have you checked to see if the cooler fan is rotating?
Can you access the BIOS and check the CPU cooling, to increase it?
 
I have removed the cooler, cleaned etc. Same with the full PC I have dusted it out completely. The cooler fan is rotating. I have even put all the fan speeds in the pc on full capacity (which doesnt help)
CPU is Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz 3.60 GHz

Roughly, what is the size of the cooler? It's possible that it is just too small to do the job.

No its not a stock cooler, its a xigmatec cooler

That should be reasonable then.

I think the most telling thing is the idle temperature 50-60 degrees. That too high for a xigmatec.

The simplest thing to do would be to replace that cooler with a better one and see what happens. It may seem stupid (because there aren't many things that can fail with a heatsink) but there really aren't that many alternatives. It's possible the sensor in the CPU is failing and giving a false reading, but that is unrepairable. So, my advice would be to try a mid-range cooler.

I'm going to let someone else make a recommendation, though, because mine would be a few years out of date!
 
Idling at that temperature is too hot IMO.
You say it's idle but is it actually idle... Have you checked task manager to see if there's any rogue processes running? What percentage utilization does the cpu have when you are not doing anything?
 
I agree with the temp. Idling is like when i first switch on pc and let it sit for like 30 mins and the utilization is like 2-5% so i know nothing is using it apart from windows. Hope that makes sense
