Thanks folks ! Cost me 4k.
@Arun1: I am not sure about the switch like things ? Which pic did you spot those ? As far as performance goes, it is exactly as advertised in reviews all around. To give you an idea, with the CM Hyper 212+, I was reaching 80-82 degrees above 3.6 GHZ. With this one, temps @ 4GHz don't cross 70 ! And with the air conditioner on in the room, temps don't cross 60 at 4 GHZ.
