• Review: This fan blows plenty of air and it's very quiet for what it does. Sure, the LEDs may not be as bright as the picture, but that's because the blades are black, not clear.

• Review: These are some of the best case fans I have used. While you can get higher output units you cannot get ones with anywhere near the DBA output of these particular fans period. The Lighting can be disabled if you do not want them so this is as far as I can tell one of the best fans on the market. I also use them (Generally in dual implementation on CPU coolers of the tower variety) in 3 PC's, and has of of yet never had an issue of any type with any of the 6 I currently use in this way. I also use them where cases allow 120mm fans (intake exhaust etc) in the cases with the same verdict. So if you want some of the best fans out there with these specifics there is not another unless you don't mind tons of noise.

• Loud fan, for some placements

• Rating:
• Review: Okay, Ive tried multiple speeds for this fan, tested it inside and outside of the chassis, but this is just a loud fan! If you dont mind the noise then feel free to purchase this fan.
  
  EDIT: For some reason after placing this fan on a more sturdy fix, and the other in its place, the noise went away. It might be because this fan seems a little more "plasticy" then the other one. So it may be loud depending on what you attach it to.
  
  Also, if you want it for the LED, it does not emit much light, it only makes the fan look red.

• Great fans, LEDs work fine for me.

• Rating:
• Review: I bought 3 of these to use in my most recent build. The red glow is pretty bright even behind the filter screen on the front of my Antec 300. They've been going strong for about 3 months now, and they help a lot to keep the air moving around. I do agree with the other reviewers that they are a BIT loud, but I personally don't mind them at all.
