Whats your 24/7 Core i7 920 and temps under water?

I hope no one is expecting a solid improvement in clocks over air....

Just look at benchmark stables speeds--people are hitting 4.4-4.5GHz on air and the same chip is barely cracking 5GHz (if that) at -110C. Heck, FUGGER got 5GHz on air and 5.7 on cascade with a chip DrWho? brought for him to play with.

Taking 15-20C off will maybe get 50-100MHz for most people (if that).

EDIT: long story short, these chips were designed to be indifferent to temperature. I recommend closing Core Temp/RealTemp, tuning your OC to max clocks that are stable, then tuning your cooling to reduce noise as much as possible without sacrificing stability--that's the way to make the most of a WC system on i7 (reducing noise).
