Do not fool yourself by taking the non-K version, it does not overclock, the multiplier is fixed.
The original cooler is noisy, Intel was better before, hence one less star. I put a Prolimatec Megahalems instead, I want without pushing 4.6Ghz (46 x 100MHz) at 1.28v with cooling with a 12cm fan at 600 rev / min. Needless to say that the PC is super responsive (8GB RAM, SSD Vertex 3).
Intel thank you, and the next, a silent CPU cooler will be much appreciated!
