Cooler Master BESTED themselves with the Hyper 212 EVO! It IS in fact MUCH better than their own much Vaunted V8 cooler in EVERY WAY!
IF you have a decent mobo (ASRock Z77 Extreme 4 here!) it is QUITE possible to hit that 5 GHz with an i7-2600K (my ROCK stable OC, I use dual Corsair SP-120 fans on mine) - 24 hours of Prime 95 and no one core gets hotter than 87 degrees, and the package temp never exceeds 84! This is WELL within the margin of safety, as thermal throttling (TMAX) occurs at 95 degrees on an Intel SandyBridge K model processor stock (unless you tweak it higher, which I would NOT recommend!) - even using a higher Bclock - which increases memory and PCIe speeds too!
For a 95 watt TDP or lower CPU the Hyper 212 EVO is ALL you should EVER need! OFC I have a corsair Carbonite 200R decked out in AF-140s, as well as SP and AF 120s! - EVERY fan slot is occupied and pretty much at max speed, still SILENT IMHO!
