Ordered H60 liq cooler for 3570k

I bought a corsair H60 liquid cooling system for my i5-3570k, anyone running the same hardware have any recommendations for overclocking? I'm using an MSI Z77A-G43 mobo in a HAF 912. I'm thinking i have plenty of room after looking inside the case, but I'm not especially familiar with which multipliers I can set and what i should do with BClk and other settings like voltage and various options, based on my H60's cooling capacity.

I read a 3570k-specific guide that suggested NOT to modify base clock, and another one that suggested 10% bclk increase...

Just change the CPU core clock multiplier, don't bother with BCLK overclocking. It may de-stabilize your SATA ports and stuff.

Based on my experience with a similar setup, you should be able to hit 4400 at a reasonable voltage. Your chip will vary, but to hit 4500 my voltage was approaching 1.4, so I kept it at 4400. Temps were not a problem.

You may need to disable to C-states to prevent instability when overclocked (C3, C6, package c-states), but perhaps not. You can try with and without and see what happens.

Other than that, there are basically two things that you'll need to mess with: voltage, and multiplier. Don't use fixed voltage, use offset or additional turbo voltage. Bump your multiplier up to ~42x and stress test with Prime95 or IBT. If it crashes or throws an error, increase your offset or additional turbo voltage. Move up to 43x, then 44x. 44-46x will likely be where you'll top out with reasonable voltage, which is generally agreed to be less than 1.3v as reported by CPU-Z while the CPU is loaded.

I personally run my chip at ~4.4ghz with around 1.2v. Heat output increases exponentially as voltage increases, so even though I can get 4.6 stable, it's well into diminishing returns.
