Purchasing a heatsink for i7-920

[jyeh]

I'm about to finally start overclocking my 920 instead of keeping it at stock. I've been attempting, but having a stock fan... have lowered my capabilities. I was wondering what fans I should buy to best overclock my chip. I've been looking and saw that Prolimatech armageddon would be the very good, but the heatsink costing 60 bucks is a little much unless I can't hit 4.0 gHz without... I'm also limited on space because I use an Antec 900.

1. I'm looking for some direction in overclocking the chip.
2. Some suggestions to which heatsink to purchase.

Thank you for your help in advance!

I used this guide to OC my i7-920 to 3.82 GHz; very stable: http://www.tomshardware.com/forum/263043-29-1156-core-core-overclocking-guide

When you pick a heatsink, make sure that the heatsink will clear the RAM; especially the RAM in slot 1. Tall RAM will interfere with certain heatsinks.

For you information, I have Corsair Dominator RAM (tall), but my CM V8 heatsink has no clearance issues. (EVGA Classified motherboard).

The i7-920 DO overclocks well. Read a lot about overclocking, and backup the computer, before changing settings. Do the OC in the BIOS, and gradual increases.

Any other suggestions on heatsink/fan recommendations?

If you have enough clearance between the lowest cooling fins on the heatsink and the top of the RAM modules, then go for the Prolimatech Megahalems.

I cannot use the Megahalems because I have the tall Corsair Dominator RAM modules. (Interference in RAM in slot #1).
