Pros: Very quiet and moves lots of air. Unique vibration absorption system. Nothing about this fan indicates it will break down soon. Comes with a 6 year warranty.

Cons: Can be used for exhaust only. No leds (if you are into that sort of thing).

Overall Review: Because fans are pretty cheap I bought two to try out. Without question, the ARCTIC COOLING Arctic Fan 9 (AF9) beat the other. Since I am not supposed to compare competing products I will not list the other fan; I did review it.

Pros: Works like an iPod should. Great price.

Cons: Mine came with many scratches to the screen and a small dent on the back panel.

Overall Review: I know you take your chances when you buy a refurbished model, but given the condition this one came in I would have paid the extra for a new one. This iPod seems to have been well used before it was returned, and obviously used without a screen protector. Now I get to look forward to years of use noticing the scratches I didn't put there. (I have to admit I am more picky than most.)

Pros: Very quiet fan at a great price. This fan is certainly worthy of the many great reviews it has received.

Cons: None unless you need more airflow.

Overall Review: I would buy this fan again.

Pros: Very quiet. You cannot hear the fan unless you put your ear right to it. Moves a lot of air for an 80mm fan. Green led goes great with my Raitmax Smilodon Extreme Black case lights.

Cons: Price. Definitely worth more but I'm not sure this much more.

Overall Review: Bought this along with a very popular Ener something or other. Both are equally quiet This fan does move more air.

Pros: It is small but still moves a lot of air.

Cons: The thing is a bit loud. After installing this fan, my wife wanted to know why the computer was so loud. I did use it as an additional side exhaust fan, not a replacement for another. The fan was still the loudest piece in my system, and my system is not at all silent.

Overall Review: Because of noise I ended up removing it.

Pros: I love the no tray concept! The design works perfect and the unit seems to be well built. Effortless installation and removal of drives, hot swappable ... what more could you want?

Cons: The lock seems a little cheap, but it works.

Overall Review: I would definitely recomend buying.
