CPU overheating, Why?

[Undertaker225]

I hope this is the correct place for this topic. I have noticed in my little brother's computer that the CPU temperatures are reaching 60 degrees Celsius on idle and upwards of higher 80's. I thought originally to replace the thermal compound. I had done so without any major improvement barring a few degrees. I was wondering if anyone could come up with any theories as to why this might happen.

 

Admittedly, the computer has shut off due to what I expect to be overheating as there was no BSOD or anything of the sorts. Any theories are appreciated.

 

Thanks in advance.

what system is this?

 

 

[DemiGod]

Just gonna give a list of possible causes some of them mighy be dumb etc but just trying to help

 

1. Too much dust in heatsink

2. Broken fan ?

3. Maybe the temperature sensors gone crazy

4. Internal compound under the lid is gone ?

if its idling that high then it sounds more like the heat sink isnt mounted properly. Thats the most common issue with high idle temps on air.

This is an AMD FX system, custom build.

1. Just cleaned it with Isopropyl Alcohol and re-applied thermal compound.

2. Fan is operating properly, or at least it's spinning at a speed where I can't count rotations without help from software.

3. Perhaps, but that wouldn't explain the random shut-offs.

4. Just re-applied with some pretty premium stuff.

Thought about that too, however, I have remounted it a couple of times, each time re-applying thermal compound just to rule out both the thermal compound and heat-sink sitting. Is it possible that if the CPU was damaged through time when it shut-off that it is not runs hot because of a short of some sort by heat-warping?

The thermal compound under the lid is possible if it is a non soldered IHS, if the cpu was having issues itself it could also be a damaged cpu. OR a really bad heat sink but like 60c on idle is very bad.

overclocked?

Say it were a damaged CPU component, how would one be able to narrow that down to be sure?

 

Thanks again for the help.

No, I don't mess with overclocking. It's for my little brother (13) , he won't be able to tell the difference anyways.

Stock cooler. But I have never seen a stock cooler run at that temperature at idle. I would understand it being a little hotter, but 60's for idle?

60s for idle is very odd, Unless it really is just a bad sensor, if the cpu thought it was really hot it would still shut down even if it was not actually hot. If the heat sink is getting really hot at idle then it could be a bad cpu, if the heat sink is mostly cold that it could be a sensor or just a really bad heatsink. Computers are annoying in that every issue has a large number of possible causes.

Yeah, that's what I am starting to realize. I think my current plan, since I have, in my belief, completed the realistic troubleshooting steps, is to replace the CPU/motherboard. Would you agree with this step, or do you think that there would be a better resolution prior to calling it quits on the CPU?

Hold on, Did you check the temperature reading in the bios or just in software in the OS

I used a third-party program to detect the CPU temperature.

 

Sorry for the delayed response. College is killer.

did you evert get this sorted out?
