CPU Burn

Try removing or impair the CPU cooler. :)

Normal use, that is no overclocking - a failed fan could do the trick. With overclocking, a low quality fan, or a worn out fan, could do the trick. The more you overclock the CPU, the hotter it runs, because of electrophysical "reactions" inside the chip. If it runs too hot, the silicon just breaks, and causes the CPU to not function properly.

Clogged heat sink will cause the CPU to overheat too. I had a computer brought in that was so full of dust, the dust acted as an insulator and the CPU shutdown within 30 seconds of start up from overheating.....the user brought it in thinking they had a virus. Jim

Bad thermal paste can also do the trick by not getting the heat to the heatsink. If there is too much thermal paste, the heat can't get away from the processor and the paste is acting as an insulator. Too little and it's like not having any paste at all. Bad designs of heatsinks can also cause this. I still remember this one heatsink that just couldn't cool off any Pentium processor. Boy, those were some mad customers. Of course there is also the little thing that happened to one of my friends when he was in college. He noticed that his newly built system was running really hot as in the case itself was almost too hot to touch. When I noticed that it wasn't seeing all of the memory on his graphics card or all of his system memory, he finally took it apart and found out what had gone wrong. There was still the piece of plastic that protects the top of the processor still firmly attached. Other things that can melt a processor is a motherboard with bad thermal sensors (that might think the processor is cool and turn the fans to low), small cramped cases that can't get proper air flow to things that need it, gummi bears in all of the air holes (I didn't think anyone could yell at their kids that loudly) and of course putting a computer into a dusty, non-ventilated, cabinet because "computers don't need air. They don't get hot". If you know what you're doing and/or realize that the fans on your system are there for a reason, it is very rare for a processor to burn/melt. Famous last words: I'm invincible!

I heard many people saying about their CPU is burn because of overheat, but I never experience it. I turn on my computer all around the clock. I am wondering what could cause a CPU to overheat so that it burn out because of the heat.

A) poor cooling B) poor ventilation for cooling inside the computer (dust bunnies in the fans usually) C) air bubble under the heatsink D) overclocking without knowing what they are doing (hey, cool what does this setting do?) E) poor ventilation outside the computer (running inside a cubbyhole in a desk with no air outlet the hot air recycles into the computer heating more). edit: F) That fan is too noisy...

I think the last time I took my processor off and put it back on (long story) I must have used to much paste, because the temp gauge is indicating its several degrees higher now than ever before. Thanks for the tip, going to have to check that out. :doh:

Computers have needs as well, they need to eat and what a great treat! :)
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

Most modern motherboards will cut out if the CPU overheats, even if the fan fails. In the old days this was more realistic. Also todays CPU's can handle temperatures of 80 deg C, without causing damage. I wouldnt recommend them running at that temp for long term though.**

Since the early p4 days, the chips have had an internal heat sensor that would throttle the chip down fast enough to surivive the complete removal of the heatsink. P3s would crash but not thermally self destruct. At the time AMD didn't have a thermal diode on the chip and would catastrophicly fail if all cooling was removed, but IIRC they've since added one.

Yeah, it's clear that the people designing most higher end computer furniture are strictly interior design types and have no PC knowledge at all.

... Also an improperly installed cooler fan may result in permanent damage to your CPU and Mainboard's socket for CPU. I like the idea on DUST. I've seen it so many times. Carpets and rugs do make this dust DOUBLE when you case is near to ground. Signature? what signature!? This is me!!
