Pros: Keeps my i7 3770K at 22 degrees Idle. Maxium temp I have gotten so far is 52 degress and that was with a 30min Render from Maya.
Cons: HUGE!! Not that this is a bad thing but to make this fit I had to take the heat spreaders off one of my ram chips. Also make sure you have a full tower case, I don't think this would fit in much less than that.
Overall Review: So far a great cooler, I would like it to tighten down a little better on the cpu but I guess it is tight enough.
Pros: Cannot be slowed by anything.
Cons: Killed my wallet!!! But you get what you pay for here.
Overall Review: Great looking and more power than you may need, but you can brag to your friends that you have the best.
