No ty, my cheapo Antec H2O 620 with some decent fans is enough for an I7 980 @ 4.5 Ghz and 1.4v![]()
That's pretty lucky
I hit a wall at 4ghz with my i7 860 and an antec 620, moved to custom water and hit 4.6

That looks uglier than if you had just gone for a good air cooler![]()



4 Ghz @ stock volts, 5 mins of Linx:
Anteck Kuhler H2O 620 - 70 degrees
Intel stock on Q - 87 degrees
Intel stock on P - 81 degrees and VERY LOUD!


OOH LA LAI fixed my temperatures
At first they were going up to 99 degrees in Linx at these same settings and my PC crashing around test 8-10:

What I did was move my third Xigmatek fan from my graphics cards intake to use as a top case fan intake blowing onto the CPU area, and then the H2O 620 has two Xigmatecs exhausting in a push / pull setup.
So three of these fans, - one as an intake, and two on the radiator exhausting + an Antec H2O 620 is epic:

Maybe I should buy another two for my intake fans? They are completely silent and push loads of air.

GFLOPS seem low?
My 2700K at 4.6 pushes well over 100? Is that normal?
