Really, the stock intel cooler is ok.
It will get noisy and will not cool as well as it should under load.
But, I think exotic cooling is not needed.
I have become a bit jaded on the subject of haswell cooling for overclocking.
How high you can OC is firstly determined by your luck in the bin lottery.
I had high expectations from the Devil's canyon parts and their better thermals.
I found out that the thermals really do not matter unless, perhaps, you are a competitive overclocker.
Haswell runs quite cool, that is, until you raise the voltage past 1.25v or so.
Once you go past 1.3v, then you really do need very good cooling to keep stress loads under say 85c.
But, the consensus is that voltages higher than 1.30 are not a good thing for 24/7 usage.
I have been unable to find any official Intel recommendation on what is a safe vcore limit.
If you are an enthusiast, you can go higher.
Even if you can handle the heat, how much do you really need that extra multiplier from say 4.4 to 4.6?
My thought is that it is better to use the exotic cooling funds for a quieter and less expensive air cooler.
I suggest at least a tower type air cooler like the $30 cm hyper212. It will cool decently and be quieter.
If your cooling budget is around $65, then look for a noctua or Phanteks cooler with 140mm fans.
I would avoid the all in one liquid coolers unless you have a small form factor case with limited cooler height available.
