Hi! First of all I'm new here as a poster, although I've been lurking for years. I've just put together my first brand new system in a looong time, after upgrading my previous gaming machine more times than I can remember.

Spec:

Intel Core i7-2600K 3.40GHz
Gigabyte P67A-UD7
MSI GeForce GTX 580 Twin FrozR II
G.Skill RipJawsX 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz
Corsair HX 850W ATX Modular SLI Compliant Power Supply
Corsair Hydro H70

I've got it to 4.6Ghz, with temps after an hour of Prime95 blend at 50 - 53. This is with all voltages at auto (dropping even one notch caused instability).

I have a few questions, mainly regarding cooling. At the moment I have the H70 fans set up as an intake, as I was concerned about case pressure (2 x 200mm exhausts, 2 x 120 and 1 x 140 as intakes). I plan on adding and upgrading the intake fans so I can set the H70 fans up as exhausts. Would this be worth doing? Also, I am using the stock H70 thermal paste - does anyone know if this stuff any good, or would I benefit from changing it? The same goes for the H70 fans - at the moment I am using one stock and the NZXT Phantom 120mm case fan. Worth changing?

The other issue is the UD7 BIOS. It is version F3 at the moment, but I can't flash it either from file or the Gigabyte site - I get a "not a valid BIOS image" error.

Any help would be appreciated, as would any other comments on the system. I'd like to get an "as high as possible" 24/7 OC.
 
It's not that loud actually - the worst noise comes from the stock H70 fan, and this more of a pitch than a volume thing. The 120 intakes are the case stock fans, which look like rebadged Fractals to me. The 140 on the front (Fractal 600rpm) makes barely any noise at all, but at the same time I don't think it's helping the cooling that much. I think even with the H70 fans set up as intake I have a negative pressue thing going on.
