[H] Time to replace my CPU cooler

[_ Winterlight]

After seven and a half years my CPU cooler = Thermaltake WATER2.0 Pro 
Closed-Loop finally died. I am planning on going air. I have Intel Core i7 
4930K on a Asus P9X79-E WS. Stock is 3.4Ghz with 3.9 boost and I would like to 
be able to run 4.2 which is what the Asus Auto Overclock sets it to. So what 
cooler should I be looking at?  Thanks!
