How to cool i7 2600k?

What do you mean by little? The stock intel cooler can easily handle clocks up to 4ghz!
I would purchase the cooler master hyper 212+ over the H60, it actually performs much better and is half the price!
 



While i really do like the H series coolers from Corsair as they free up alot of room in your case and are pretty decent coolers aswell, i would say for price/performance you are much better off with a Coolermaster Hyper 212 Evo.
