cooling question and volts

[ikilby]

All,

just about got bits for new rig:
i7 920 D0 CPU
Gigabyte GA-EX58-UDA Motherboard
Corsair XMS3 6GB (3x2GB) DDR3 PC3-10666C9 1333MHz Triple Channel (TR3X6G1333C9)
Prolimatech Megahalems Performance CPU Cooler
Artic Silver 5
and lastly managed to grab
VTX ATI Radeon HD 5870 1024MB GDDR5 PCI-Express Graphics Card

So I hope to try and get 4.0Ghz out of this chip and I have never OCKD the i7.

So firstly for the Megahalems cooler - 1 or 2 fans, and any recommendations for the best fan to keep the cpu cool at 4.00Ghz.

Secondly I know I will have to up the Voltage on the CPU and maybe the ram.

So What is max volts for the i7 so I do not kill it, and what is the max temp when running full chat at 4.0Ghz.

I can ensure that I do not reach those temps and Volts.

Thanks all

nice rig

you should be able to get 4Ghz under 1.35V, which should be fine for that cooler, might be able to go a lot lower to keep the temps down.
2 fans are always better than 1
RAM voltage just set it to you RAMs default 1.65ish and once you have a stable overclock on the CPU either overclock the RAM or undervolt it.

i have my CPU at 1.275V for 4.2Ghz
