How come CPU temps DONT decrease with decrease in voltage?

[Camaroz06]

Hello again all,
I have got my E6600 running at 3.4ghz pretty stable, I started it out at 1.425v and backed it down to 1.395v. When running orthos small FFT the CPU temps seem to be the same even though the CPU is pulling less power. I figured consuming less power, putting out less heat...am I missing something here?

THanks
Eddie

they dont change even 1 degree? this could be because of an increase in room/ambient temps, you have speedstep/c1 or some other thermal control enabled in bios so its throttleing the cpu, among other things. also where are you reading the temps from. also try orthos blend and see if theres a difference between 1.425 and 1.395

Hi Ghost,
I am not too sure but I think blend might be running a degree or 2 cooler, but I am pretty sure small FFT doesnt run any cooler. Oh and I am reading the temps from core temp. Is this alittle weird? I would think going from 1.425 -> 1.395 is alot, oh and I think with vdroop the voltage is 1.36 (looking at uguru) when under orthos load.

Thanks,
Eddie

Maybe your IHS needs sanding, I know this sounds unrelated but it's not. When there is bad transfer of heat from the CPU to the heatsink then heat will still lock up inside it and only escape at the rate it can be moved to the heatsink.

man dropping my voltage on an overclock (1.45 to stock) lowered my temps a good 6c idle . my guess is the same as firewolfs.
