I used to use a lapped TRUE black on my i7 rig, i replaced it with a Prolimatech super mega, the TRUE actually cooled a little better, with the TRUE being lapped maybe helped a bit, but it has the advantage of being a bit slimmer, therefore it's not as apt to block ram slots.The ture has nothing on the Megahalems from what read about it when i was looking to buy a good air cooler.
