CPU cooler for Haswell are overrated.

Just have one next to me right now, 4.4Ghz OC, core voltage Auto (BIOS says it is 1.22-1.23V) and with a Xigmatek Thor's Hammer plus cheapest 120mm FAN from eBay stays under 60°C no matter what (even 12h on Prime95) while having temperatures like we are having right now. In a Fractal Design ARC MIDI R2 with default FAN configuration.

Would have posted some benchmarks but unfortunately the configuration lacks proper RAM, using a emergency 1GB DDR3 at 1066Mhz right now
