How hot can a p4c get?

[JSt0rm]

Ok you guys talked me into atleast trying a overclock on my 2.4c. I've locked my pci bus so no worries about my audio card but I do have stock cooling and was wondering how hot is to hot?

FSB is at 230 and I'm reading 63c from the msi corecenter thing but I hear those arent accurate. That 63c is under prime95 load. Its alot less idle.

Can I push it to 250 or 240 or should I just be cool at this?

Well is it stable in P95?

What is your core voltage?

If it's slighty unstable bump up your Vdimmm first..

How long did P95 run for?

65C is safe but your getting warm on a P4 ( not dangerous though )

I would shoot for better HSF combo, and look for about 50C loaded.

1.5250 is the Vcore

p95 has been running in the background for like 2 hours now. Everything seems stable.

Does this cpu throttle at 69c?

The thermal throttling and wher it occurs is hard to guage...There are many boards that have been shown to read quite different temperautres....I have had my 2.4c @ 3.55ghz with 1.67 vocre and running at 70c with my old Alpha heatink and it never throttled and completed prime95 six hours....

When I got my swiftech with a solid copper core and a 92mm fan the temps never reach the 60's anymore....

I would say shoot for low 60's cause with the summer about over I doubt you will really see the extreme heat it could hit....

It appears you are running stock heatsink and that is obviously the limitations...spend 35 buck or so and get a swiftech, zalman etc type of copper core heatsink and use with a 80 to 92mm fan and I think you have some room to oc....With 1.525 vcore and only at 230fsb with those temps means you likely will hit limitations. Once you start bumpingthe vcore then the heat will grow even faster...

I'm at 240fsb now with stock vcore and cooling. I think this is the limit. I tried to hit 245 but it would'nt post. I'm happy with this for just messing around for a few hours. The return was worth small work. 2.9ghz on stock cooling really doesn't seem that bad. Under prime95 load I'm at 66c but under doom 3 I'm only at 62c. Thanks to all who talked me in to at least giving it a shot.
