Processor Warmer than Overclocked?

[Belgarath]

Processor: Intel C2D E6750 2.66GHz 1333FSB
Alright, my processor's running at its normal speed on an Asus P5B motherboard (1066FSB but it supports E6750 and "effortless 1333FSB") and it's temperature when doing nothing is 30C at the start up and after playing a game around 35C-40C. During a game it's around 45C and 47C-52C while playing Crysis.
Now, my friend has the same processor, but a different Motherboard and OCed his to 3.0GHz. It runs at 25C while playing a game.
Help?

I read a thread somewhere that the BIOS of this mobo sets the voltage too high, but I'm not sure how to change the voltage - please tell me if you think this is the problem.

Any ideas?

Does your friend have the same CPU fan and heatsink? Your friend might just have a better cooling system.

That said, Core 2's generally don't need a big voltage bump, if any, to overclock a few hundred extra megahertz. As for how to change the overclocking settings, you should consult your motherboard's manual. I don't own a P5B unfortunately, so I am somewhat unfamiliar with the BIOS layout.

We have exactly the same processor and heatsink. I'll look into the manual, thanks.

Edit: I found out how to change it, and I tried to, but the lowest I can get it to is 1.25V, and before it was around 1.30V.

The current Core 2 processors run at 1.25V by default. That's the normal stock voltage as far as I know.

A modern proccessor gives out more heat per square centerm,eter than the average house hold iron.
