What motherboard have you got?
This is really good question because if you have an early am3+ board or a budget one with bad vrms it will not be able to handle the amount of power this chips need when it gets over clocked.
Thus if you have one of these boards there will be no point to get a cooler as when you over clock it your mother board will just throttle it back any way.

Ha.
Assuming the board's up to it, for air cooling I'd strongly recommend the Be Quiet Dark Rock Pro 2. It can keep my 4770K cool at 1.35v (65-70C at load), and people usually say you can only do that under water.
You only need this level of cooling if you want 4.8GHz or higher though.
If it's a poorer quality board, you may be limited to 4.2-4.3GHz overclocks, in which case a £25 cooler is more than enough. The Coolermaster Hyper 212 for example can do 4.5GHz.
Maybe you've got a lucky 4770K there?
Custom water can't keep my 4770k under 70 during Prime at 1.17v.
I think Haswell chips can be a bit of a lottery both in terms of overclocking and temperatures. So possibly not the best thing to base the performance of a cooler on?
Sounds more like you have a bad chip. The cooler is excellent, check the reviews.
did you take into account the BAD temp sensors on AMD chips? 8 cores @ 4.5 under 70c is a no no on air. unless the chip is shouting off core as they do under full load
what you talkin bout willis?
