I agree with this, but with that type of cooling you should be able to push 4.8ish 24/7 without a problem, just depends on the chip.

You will find a point during your overclock where it takes a TON of voltage for the next 100mhz, find that point, drop down one, and call it a day!

I'd feel OK with 1.45 under water. Honestly I might go 1.5 if it's really cool and the 3930K was only $200, but at $600 I'm going to play it safe.

there's no definite answer. every CPU batch and computer is different. How efficiency is your Case cooling etc. CPU is not the only thing that heats up, the motherboard chipsets also heats up and that will regulate your CPU temperature also. But 360mm radiator custom loop even with the worst setup would still be better than your H100 im sure.

You can find your H100 in this video - http://www.youtube.com/watch?v=nP8Q-7Mdztg

Where guys from Asus and Newegg overclocking 3960x with H100. High voltage and normal temp wheee.gif But what was the room temperature? FPU test in AIDA64 it's pretty heavy load.

My temperatures are higher and i'm on custom water (water T about 30C). I've got 4,9 GHz @ 1.45+V (VTT & VCSSA are very high) and during 15 hs of Prime 95 Blend I've got up to 80C on hottest core. And with this CPU I don`t want to use Linpack (LinX) anymore tongue.gif Under this thing at 1.5V it was 91C (and RealTemp showed me a red LOG).

So stay below 80-85C under stress tests and you will be fine (but you can have a problems with CPU anyway wink.gif Just be prepared for this).
