Intel E2140 runs at 78C and lives!

I had a job to mend a PC that would run for a while and then freeze. If you warm booted the same thing happened but I noticed that the more you re-booted the shorter the time before it froze.
I checked all the fans were working ok and thought it might be a software problem with a scheduled event going wrong. No joy.
Then I went to have a look in BIOS and all seemed normal in the power saving department and then I browsed through the chip configuration page and WOW! - there was the processor temperature of 78C!!!Something wrong!
It should be in the 40's.
But the fan was working ok and it had a good big ally cooler on it. Not too much dust in the fins. Strange.
Then I picked the box up to look at something and the whole fan/cooler unit moved! The cooler was not clamped properly to the mobo and therefore not to the chip. Three of the four clamping pins were loose!
I cleaned off the old grease, applied new grease and clamped the cooler properly to the motherboard and it now works like a dream. It really says a lot for the ruggedness of Intel chips to survive such overheating.
Have you had a chip run at 78C and live and not be cooked?
Have you had these cooler locating pins pop out by themselves before?

The fan on top of the Pentium is either not working or something is wrong with the power saving settings and the fan is stuck on low speed. Check the speed in BIOS.
Take off the side panel and look to see if the fan is running. Don't trust just hearing if a fan is running because the graphics card could have a noisy fan and the PSU has a fan and their should be a case fan or two as well for a P4.
Also, check to see if the fins of the heat sink are clogged up with dust. They often are after a time. Remove the power supply cable and then unscrew the fan on top of the heat sink. With a soft paint brush and a hoover, brush the dust into the hoover intake. Don't touch anything on the motherboard with hoover pipe or your fingers as static electricity can do damage.
The P4D is about the highest wattage chip ever and pulls about 100W which is a lot of heat to get rid of so a good fan/heatsink setup is critical. An Intel Core2Duo runs at half the power for better performance.

It's a good thing you've flip the casing and noticed the cooler assembly is loose. You wouldn't expect the cause of problem would come from this very simple assembly error. I guess the thermal grease did its part excellently. That processor is really tough to operate at almost twice its recommended operating temperature. If that is AMD then its really toast. It appears you are a veteran trouble shooter to arrive at checking bios temperature. So I would monitor the time of boot sequence when I'm in similar situation. Thanks for sharing this great experience of yours.
