Computer Keeps Shutting Off Due to Overheat

[Wubble]

My computer keeps shutting itself off because of an overheating issue. My system monitor shows that all temps are ok, 30C/80F. I have not the slightest idea why it is doing so.

Could my problem lie with my generic power supply unit? Here are some system specs.

I forgot to include that my case is open and I do have a fan blowing into the case, so that should help out a lot. It keeps the temps steady as well.

hmm. at what point does it shut down? immediately or after some usage? is your cpu fan getting power? also, can you list your cpu temp as well as your system temp? thanks we'll figure it out.

The processor heatsink - does it get hot? If it gets hot, that means it's working. If it stays fairly cool, that means that it's being insulated from the CPU somehow, and so not doing it's job.

As of right now my CPU temp is at 24C/75F my System temp is around 24C/75F as well. I touch the heatsink it seems to be fairly cool. I noticed this the other day but I was puzzled myself. I even went out and got some silver thermal compound and applied it to the back of the heatsink.

What makes you think it's an "overheating" issue causing the problem?

 

[Wubble]

When I reboot the first thing I see on the boot up screen is a why it crashed. I says due to thermal issues (overheating) the cpu shut itself off. It says almost exactly that.

 

[boshuter]

Well it sounds like your temps are fine. I would make SURE the heatsink is properly applied; 1. Did you clean the heatsink and cpu before you reapplied new thermal compound? 2. Is the heatsink making good contact with the cpu? This is hard to check, but just make sure it installed with no issues. I really don't think any of this is a problem with the temps you are reporting, but it's worth double or triple checking them.

Go into bios and disable the thermal management feature completely and see if the system works. If it does, I would try reflashing the bios, if that doesn't cure it you may just have to run with the thermal management turned off. I don't see that as a problem, the cpu you have does not run hot and it's pretty hard to kill an Intel with overheating, especially the one you have.

The suggestion to feel the heatsink to see if it's working is IMO not good. It works if you have felt enough of them at different temps to know what it should feel like..... but telling someone to see if it's "cool/warm/hot" is probably not going to work since what feels warm to you may be cool to someone else.

I'll recheck the heat sink and thermal compound. If it reboots me again I'll try what you said and disable the thermal management
