After swapping case fans & jigging some wires around I installed the temp monitoring utility yesterday & it reported the cpu @ 112 degrees! I rebooted & checked the bios and that also had the same temps.
I shut the pc down & a wire had dropped into the stock intel cooler & stopped the fan from spinning, once this was free & the pc restarted it ramped up to full speed.
I could then no longer enter the bios, it just hung & then took 5 attempts to load windows, it was just rebooting half way through. The fan gradually slowed down whilst doing this until it reached its normal inaudible speed. After that the pc appears to be fine again.
Now, is 112 degrees even possible & is it likely I have caused damage ?
 
First of all 112 degrees is entirely possible especially with no working fan and yes it could possibly have fried your CPU and maybe even your mobo.

Also was the wire that caught damaged - cpu fans spin fast i'd imagine it'd chew through a lot of wires or atleast cut through them slightly.
 
Intel cpu's have thermal throttling, which reduces the cpu speed as the temperture increases, damged to cpu or motherboard that will be hard to say.
Not sure if it possible to course windows to be corrupted.

Try a few re-boots and run some benchmarking software ie 3d win mark to ensure all is ok.

RUBBISH!
Intel CPU's since the days of the Pentium 3 have had excellent thermal control. as soon as the onboard temperature diode inside an intel CPU reaches a pre-set limit, the CPU sends a "THERMTRIP" command to the bus. the PC will IMMEDIATELY power down.

it is impossible to kill a working intel CPU by allowing it to overheat.
 
It wouldn't have got to 112C, I thought they throttled at 95C, look at real temp for what the temp value is called.

**edit beaten... by a lot :(

You can turn the throttling off on some boards though. You can on mine, not that i ever would.

no you can't. you can turn off speedstep, which is what the throttling is, but speedstep does it when the CPU isn't being used, while throttling occurs when the CPU is hot.
 
well... have seen my Q6600 hit 107c before shutdown (ran a winwar bench at 4.1ghz, forgot to turn the fans on :) ) and it didnt throttle (at least not what I saw in CPUz anyways, although to be fair was in a rush to hit the power switch on the fan PSU)..
 
I wouldn't worry too much. that happened to an old 4000x2 of mine and it worked fine. The cpu fan wire had got itsself tangled up in the fan and it stopped spinning.

I know what throttling is. So what is Intel CPU TM function? According to my manual it's Intel CPU Thermal Monitor which is what throttles the cpu back if it gets too hot, yes? Well i can disable it on my board.
 
if the temp too high then the Windows OS automatic shut down and reboot itself but it seem it something in your mobo BIOS CPU max temp like my M59SLI-S5 at 60oC that max temp - if it over 60oC then it would shut down itself. Open then case and check the CPU and fan (you may need reapply thermal paste again) and then try again -- 112oC is too hot that would melt the paste too easily.. at my work the IT staff forgot to plug the fan speed pin as the CPU went fried at 110oC and replaced new CPU (its old Intel P2 2.4Ghz) - check your mobo BIOS startup screen
 
The chip should have a t-junction around 100oC and shut itself off immediately if it reaches this level.

There's a great video on Toms Hardware where an Athlon XP reaches 350 degrees or so and melts but since then, thermal shut-down has been included in all CPUs as far as I'm aware.

I have that video downloaded, it's pretty cool :o

Having trouble understanding your post, but it seems your saying the O/S shuts down an overheating chip.

well it does not, its through the bios and if chips shut down at 60c then 99% of
peoples chips on this forum would have stopped working.
 
I'm fairly certain that regardless of BIOS settings a modern Intel CPU will throttle itself if it reaches a pre-defined temperature. You could probably take the heatsink completely off and it would run for a short time with no ill effects.

i've done this with a pentium 4 system a couple of years ago, which needed some data transferred off it, and its owner casually neglected to mention that the heatsink had fallen off :p

i had wondered why windows took 20 minutes to boot...
