Could you blow a AMD cpu when rendering for a long time?

AMD cpu's run real hot even with good coolong do you still run the risk of getting them to hot that it will break?

I have and 1.2 gig thunderbird, I left my computer on Saturday, Sunday and most of monday while working on capturing and encoding, still works fine. Then again I have one fan in the Power supply, one fan on the back of the Tower housing, one fan on the front inside of the tower housing, of course your CPU fan, Fan on my motherboard VIA chip and 2 fans on my Voodoo 5500, a fan on my Hard drive and also, beleive it or not, it still runs pretty quite.

It's not very frequent but i have heard of them getting to worked up and setting the silicon wafer on fire, Its a horrible mess. Nah just messin what will happen if you have shitty cooling is your mobo will shut off the system to save it. and if you have good cooling, then dont worry. I have had a capture that i was converting on my 900 that i used some many stupid filters that it took 4hours for 15min of video in the 2pass mode. the sad thing was, it was a 2hr capture!

You dont want your Athlon to go above 60 Centigrade - Athlons have crappy thermal protection. In fact if you took the heatsink off it when working, it will die a thermal death. There will always be a small (very remote) risk that it will fail due to thermal reasons, but that is the risk you take with any AMD. With adequate cooling and a decent thermal monitoring mobo there is no need to worry.
Just as a matter of interest...
The P4 can operate with no heatsink as it can throttle its clock (greatly decreasing performance - but better than a fried CPU) if the thermal diode kicks in. A P3 will just shutdown and cease to operate until you reboot.
AMDs die, forever.

P.S. No, I dont work for Intel. Im AMD 75% - Intel 25%.

All this talk about frying a chip boils down to one thing. GOOD COOLING (and a properly installed heatsink ) I run a 1.2GHz o/c'ed to 1466 with an SK6 at 1.8V, and my encode jobs generally take 20 hours for 43 minutes of video (*sigh* tmpeg, what can I say?). That's near full CPU usage for an entire day.

I have fried 2 cpu's before. A 900MHz and a 1.4GHz (ouch). And this is how it happens: improper heatsink placement, and improper clip attachment. Make sure the die is actually making good contact with the heatsink; make sure the clip is FULLY ON the socket lugs. Expansion of the clip can happen when a CPU is at full usage - I learnt that the hard way.

Generally however, with adequate cooling, you should not be able to fry your chip.

As for the motherboard "features" that are supposed to shutdown the computer before something bad happens: IT DOESN'T WORK. The thermal gradient the sensors are designed for is way too low to stop a (AMD) CPU from frying if there is instant heatsink removal.
