Pros: Good airflow. Love the blue LED lighting. Flexible as it fits 200mm-180mm. Thin enough to fit in the roof of my Corsair case.

Cons: Not free.

Pros: Moves lotta air as specified , blue light looks great in my homebuilt Gaming HTPC ,, I5-3570K ,Gtx 660 , Samsung 120Gb 840 Evo ssd ,

Cons: For watching movies must be set on low setting , to loud on med and high settings for watching movies ...

Other Thoughts: Great product for a gaming Pc ,, HTPC somewhat questionable ????

Pros: I like that the fans have selectable speed. I run at 900 rpm setting. They provide a ton of air into my case. I run a 2600k at 4.5 with a H60 cooler I also have a GTX 480 which is a furnace. The two fans do a great job of keeping the case cool and I have seen around 5-10 degrees cooler temps depending on what I am doing

Cons: Fan speed selectors are on the motor and require opening case to adjust.

Other Thoughts: I replaced the two 180mm fans on the bottom of the Silverstone RV03 case with these fans. They are also thinner than the standard case fans.

Pros: Nice and quiet, three selectable speeds, easy install and neat-O bright LEDs at a great price!

Cons: None as of yet.

Pros: Quiet and smooth

Cons: The screws that come with the fan cannot reach through the screw holes. I had to cut the fan mounting so the screws could reach and attach the fan.

Screws are approx. 1/4", the fan housing is 7/8" thick.

Pros: great fan real quiet

Cons: none at this time

Pros: Moves a ton of air, and it's practically silent with the exception of a slight vibration, which I think is my cases fault. Have it running at the mid 900rpm setting and its great. The LEDS are super bright and look great. Using this fan as a top exhaust on a Cooler Master HAF 912 case.

Cons: Cant think of any.
