CPU becomes too hot

Here is build of one of my old computers.

Antec 900
P5B Deluxe
4GB (2x2GB) Kingston Hyper
E6700 (Artic cooling freezer 7 pro rev 2)
EVGA 8800GTS 640MB

Being air cooled, it is around 40 C idle (CPU), but as soon as i try doing a stress test to check max temp, it goes over 70C (i immediately stop the test). This happens in a matter of seconds, so i am wondering whats going on?

I also applied new AS5 thermal paste to the CPU.
 
Is the cooler clamped down properly?
Is the CPU heatsink fan scaling to the job?
 
Are you running any of the ASUS Q-FAN profiling in the BIOS Hardware Monitoring section? If so turn these off as I have seen it not allow the CPU fan to scale when heat is being heavily applied.

Secondly as jeremyshaw mentioned I would take the HSF off as IIRC that Arctic Cooling HSF assembly uses pushpins. Put on new TIM, re-pushpin the HSF down and check it again.

If all else fails apply a BIOS update, you would be surprised...
 
i know the cooler isnt the problem as it has been clamped down completely, but ill check the bios update and the Q-fan profile.
 
havent done bios yet, but q-fan is off.

Im not even sure i can do anything on it to say the truth as it gets too hot.

It was 45C idle, and when i tried to open a web browser, it jumped to 55, then to 67. (within a matter of a second or 2). Is this even possible?
 
:S

Yes and no

What program are you using to check these temps with?
 
HWMonitor.. Works great and accurately on my laptop, so i used it on the desktop.
 
Just for shit and giggles try out speedfan.

Also your idle temps do they seem similar to what you see in BIOS?
 
Use Real Temp or Core Temp.

If the fan isn't at full speed, then it sounds like a mounting/heatsink issue or thermal paste issue. Try the stock HSF and see how it does. If neither work, RMA the CPU with Intel.
 
tried a couple other programs before including speedfan and real temp (gave even higher value for speedfan). Amazingly, bios showed temp same as HWMonitor. Rather surprised as i thought bios arent really accurate.
 
BIOS doesn't typically breakdown the temps for each core, which is what you're interested in. The max temp of the E6700 is 90°C per core. So again, make sure the fan is at full speed and try the stock hsf.
