I am running my system with stock cooling and was wondering if when I get myself a better fan for the cpu, will I be able to lower the voltage going to my cpu? I know increased voltage results in increased temperature, but I'm not sure if it works the other way around a little.

Also, does my cpu use the voltage I set in the bios(1.37...) or what HWMonitor shows(1.31)?

PS: I cannot wait to get some after market cooling on my e6700 and get it to maybe 3400+. I haven't decided whether or not I will get liquid cooling. Maybe I will buy dual 8800's if I am inclined in a few months, if i get liquid.

Hey Ghast,

errrr, no! Think about it, the more voltage running through your CPU, the hotter it's going to get, so if:

More Voltage = Higher Temperature, then Less Voltage = Lower Temperature.

Why would you want to lower your Voltage *after* buying a better cooling. The time to do it would be when you have poor cooling, and having problems keeping your temperatures down.

The voltage range of an E6700 should be between 0.85 - 1.3525 V.

Agree with Mad-- the more voltage present-- the more waste is turned into heat-- as NO material is a perfect conductor.There is always resistance. If there was such a thing-- your power bill would be 1/4 what it is...

Superconductors are what the Mag-Lev Trains need to make them affordable to operate. Some materials become superconducting-- but at temps nearing absolute zero... they are furiously researching to find a material or compound that is superconductor at room temp. They are getting closer.

This is why OC systems need superior cooling-- faster cycles = more waste heat, requiring better heatsinks, more airflow, even liquid-cooling for PC's (yes they have them)

That's what I was looking for. Lower CPU temp = less voltage required @ same speed.
