Voltage and stability depend on the motherboard and your chip (every chip is a bit different). What is your budget for the cooler?

I would recommend this: http://pcpartpicker.com/part/noctua-cpu-cooler-nhd14

Keep in mind that you can't fit that in any case. So, what's your case?

The motherboard you have is pretty good so OCing shouldn't be a problem. As for the voltages, you'll just have to try out and see what works for you.

The biggest problem will be heat, with haswell even a slight OC can cause overheating with a aftermarket cooler. In my case I had to delid get my temps down for a 4.2 OC, now i'm able to run 4.6 without overheating using a HyperEVO 212

I think you meant to say this (correct me if I'm wrong): With Haswell even a slight OC can cause overheating with the stock cooler.

Nope, I meant it like I wrote it. Even with a aftermarket cooler the temps can still cause a problem, at least in my case, and many others I have seen and read across many forums. This can be due to the TIM and the gap between the die and the lid created by the black silicon used to adhere the lid to the PCB of the cpu.

With the Coolermaster 212 I was reaching 85c+ and had a huge discrepancy between cores, as much as 7c with a 4.3OC, after a delid replace TIM with a liquid metal TIM and a lap on the lid I went to low 60c's and only 2c discrepancy between cores at 4.6OC.

There are others with same results, im by no means recommending this in his case, but to some if they want a cooler more uniform OC its an option.

btw lapping the lid maybe only shaved 1c if that in my case.

thats the reason intel is releasing the refresh of haswell with "improved" TIM, most likely they will be soldering again, or i hope anyways. At the very least a metal contact instead of a paste.
