I have a HTPC that has an e8400 in it. It sometimes randomly switched off, most often whilst watching high-def films. So I checked the temps by running real temp.
And at idle it was saying around 70C. I couldn't believe this so decided to run the calibration, but of course the PC just shuts off after running it for a minute or two, i guess as the temperature gets too high.
What could be the problem?
I am only using the stock cooler but surely it isn't THAT bad, it works fine on my desktop that has the same CPU.
i would ruke out the faulty temp sensor since your comp is shutting down when you are running any cpu intensive apps. try coretemp or hwmonitor or everest to see whether your temps are okay and check your bios for overvolting.
I agree. Download and run HWmonitor. I use that regularly when benchmarking. But 70C in a HTPC that's most likely not even working hard is insane. My 8400 being overvolted to 1.45 for short term OCCT overclock stress testing didn't even hit 70C on air (with good airflow).
Ok I went out to maplins and bought some new paste to reseat it and while i was there picked up a new HSF. only £13 but is a fair amount bigger with a bigger fan. Just seated that, and will let you know the results in a bit. Saying I need to run the BIOS because I have changed the CPU. So need to steal the keyboard from this computer before I can do anything!
