Have you ever burned out a CPU by running it too long?
 

I've been doing some hardcore video encoding lately (about 14 hours a day). I'm wondering if this will ever burn out my CPU since video encoding basically runs the CPU at 100% the whole time.

hmm it must shorten the life of the CPU for sure

not likely- think of thousands of servers still running at at PII 266 full speed for 5 years - your CPU will look like a 286 before it burns out

Worry about moving parts

we had some problem last summer- our AC was broken and it was really hot day in office.

So what happened? Did your CPU overheat and die?

Yes, of course you can burn it out. You should never run your computer for more than a couple hours at a time. You need to turn it off every few hours and let it sit for a few minutes, then turn it back on. It should all be in the manual!

was overheat and shut down PC all the time
temperature was above 68 degree Celsius I think

Jesus. That processor will probably be around long after you're dead, I wouldn't worry about it.

What Interlude said. Lack of cooling kills processors under load, not the load itself.

The cpu should be fine.. just make sure your computer has a bit of ventilation and the fans are working.

My puter has been running for a couple of years straight now with no problems besides the occasional reboot or power blink.

Long ago, I put a desktop computer together and didn't ground out the board properly, and it burned up... smoke and everything

Course, that was the board, not the cpu
