Why do lover temp mean lover vcore?

[Mech0z]

Havent been able to find any answer to this question, but people that watercool or ln2 cool can go with lower vcore, is this because the cpu just gets more stable at the lower temp?

[Leeghoofd]

it becomes more efficient with better cooling, any electrical component that runs hot needs more juice to remain stable. Though coming from a high end air cooler to a high end watercooling ( but noise at a very bareable level) I didn't see much. Benching with phase you can drop vcore a bit for the same clock...

I thought it's opposite. Watercooling or LN2 can go higher vcore because the CPU will stay cooler so they get better/higher OCing. With air, the CPU gets too hot using higher vcore so we can't OC as high.

heat creates resistence, which creates more heat, and possible minor voltage fluctuations.

That's why I said it becomes more efficient. With lower temps you can stabilise the same clock with lower volts. But in the mean time it also allows you to go higher on Vcore so achieving a higher CPU speed.

I believe this is right but you can acheive the same clock with lower Vcore with colder temps and at the same time the colder the farther you can oc without temp probs (correct?)
