Summary: Spend a good hour trying to understand how to install it. Didn't realize the bracket was suppose to go on the back side of the motherboard since the instructions didn't say anything about flipping the board around. Otherwise than that hiccup, the install went smooth and easy. It is also very quiet and very effective cooling.
Summary: I can't really think of a con for this product, except its large. Which you pretty well know when you purchase it. For the price, its a great quiet air cooler. Especially for mid level overclocks.
Pros: Easy to install., Comes with extra fan clips and rubber noise dampers for a second 120mm., Quiet.
Summary: Easy to install in minutes, had to install the fan in a "pull" position in order to have sufficient room for my Hyper Beast Ram. Comes with an extra fan clip, so you could have 2 fans cooling the unit, can easily adjust the fan clip in order to clear ram on the right side, I just went with one fan. A great cheap alternative until I get my custom loop built.
Pros: Easy Installation, Easily add a 2nd fan, Price
Summary: For the price can't ask much more of this cooler. Bought it when idle and load temps with my stock cooler were a little higher then I was comfortable with, has done a great job keeping things cooler.
Summary: It's a good heatsink for the price, but i can't rate it 5 star because you can tilt it after the install so you must be careful to not scrap your thermal coumpound application. Performance wise, its better than stock but you will not be able to do super-overclocking. 4.5 GHz on my 2600K seem too much heatwise for that heatsink. (going over 90). But i still find it better than stock heatsink at stock speed since temps and noise are lower.
Pros: Better than stock heatsink, low price
Cons: Very Tall, go over nearest memory slot, hard to install, not fixed strongly
