Thanks guys. Yes the stock Intel® HSF (heatsink/fan) should be able to meet the normal cooling demands of our 3rd generation Intel Core™ processors. However if you are in a poorly ventalated room, or a hot environment you may find that you want to look for a replacement HSF. I do advise that you put the Intel stock HSF on the board before you try to mount it in the chassis.
