What's the highest CPU temperature you've ever seen?

I once saw 95C on my old Athlon XP machine, but I also know that it had been up to 10C warmer than that previous to it. I heard a friend tell me he once saw 140C on a computer he was fixing.

Fortunately, the highest I've ever seen with this PC was 50-52C - during idling in a heatwave (I daren't play any high-end games then, for the GPU was running close to 80C just idle!), and once after a 3- or 4-hour ToCA Race Driver 3 marathon, though in much cooler temperatures.

140C I really wouldn't want to touch that.

No, he told me he saw smoke, and when he took the case side off (very carefully I would imagine!), there was evidence that the dust inside had actually caught fire. I really don't know how a PC can get that bad, I thought the Athlon XP, which is notorious for temperature problems, at 100C+ was bad enough!

Good thing it's not true.

If this were GPU temps... I think I'd have you all beat, but that was a glitch with running EVGA Precision during a GPU Driver Update and screwing up its temp sensing LOL... I forget right off hand, I posted in one of the F@H threads, but I think it was like 1.5-1.7 MIllion Celsius

as to CPU, I've never myself seen anything higher than 55 or 57C and that was on my old Athlon XP 2200+ (original Brown colored XP 2200+), my 2nd XP 2200+ (green colored) I never saw higher than 50C. both @ Stock 1.8GHz Speeds.

the old XP 2400+ I had, never saw above 45C.

and the Athlon XP Mobile 3000+ @ Stock 2.2GHz +/- (ran @ 16.5 x 133, 266FSB), never saw above 30-35C

seems each success and faster Athlon XP I bought kept getting faster or better and yet cooler LOL.

every CPU I've had since I've never seen them higher than this (55-57C)

This was an XP 2200+, but it was very old and had been used and abused a lot, and was damaged by other devices overheating.

140C isn't nearly hot enough for dust to catch fire. if it had, it would of smoldered some, but that would mean the CPU was already dead, no way it could function if its hot enough to catch something on fire.

smoke was possible, but most likely something was shorting to create a hot enough temp to cause smoke.

140C is only about 284F, which is hot, but not THAT hot.

I've read that Paper starts around 481F or so... I would imagine dust wouldn't be much higher or lower though.

but would depend on what the Flash or fire point is for the type of dust in the PC.

in any case, any sort of Flame or smoldering for a PC, is a no no, and CPU by all rights should be still working if this was the case.

Dust comes from skin, not paper, and has a fairly low flammable point I believe.

I don't ever remember having temp issues with any athlon xp's I've dealt with. Well the 3.2GHz one I saw get to 73C but that was during a benchmark while it was overclocked.

Not to mention, you can burn something without actually having it catch on fire
