someone buy me a zalman heatsink so I can actually go about oc'ing my processor :(
1. Air cooling is never adequate for overclocking
2. See rule 1.
If you are even contemplating overclocking, invest in a good water cooling setup and make sure you cool the chipset and voltage regulaors on your motherboard and your ram in addition to the processor. Unless you don't really like your motherboard and ram, in which case, go for it. A basic rule is 500 watts of heat dissipation per 120mm fan size of radiator core. If you have a 1,000 watt PSU, you should have at least a 3 120mm fan sized radiator an adequate pump (or two if you are going to cool the video cards on their own loop) and a decent sized reservoir of treated coolant.
Performance-pcs.com is a good spot to check what is available for air and water cooling.
If you have something like a Haf X case with 140mm fans cranked up to high, you might be able to get away with a mild overclock on air cooling. but might is a funny word when it comes to very expensive gaming computer components.
