Pros: Move a lot of air, fast. Have cool LEDs because I am 5 years old and pretty lights amuse me.
Cons: I really like Antec stuff, but these fans sound like a card stuck in some bike spokes. Probably solvable with WD40, but I can't be bothered. These are like 8 bucks so I threw them out and got some new ones from Best Buy.
Summary: I received this item and tried to install it right away. The manual leaves some things to be desired, but is fine if you have purchased aftermarket coolers or installed heat sinks before. The problem I ran into though, is that the heat sink does not fit Intel's 775 socket as advertised.
