Moves air, looks good. LEDs aren't as bright as the picture shows.

Comment:
Its good but the lights arent bright.

Comment:
nice, bought these to go with my coolmaster case.

Comment:
The red LED looks great but its a little noisy, gonna try using a controller to adjust the speed down a bit.

Comment:
Great buy, nice looks and moves plenty of air.

I got the fan to use as a case cooler and it does exactly that. It's placed backwards to pull out the hot air from inside the case. The only reason being is I have another 120mm fan cooling the CPU so I wanted the hot air from the CPU being forced out as quick as possible. The red LED's arn't as bright but still look awesome in the dark!

Comment:
This fan is excellent in moving air. It is quite than most 120mm fans. The lights are not as red as the picture displays. Would be nice though. But I bought it for the air movement and the noise level and it does that without an issue. They where added to my Cooler Master 840 case and it brought the case temp down by 10 degrees. Great fans in moving air and very quite.

moves a ton of air i had a considerable temp drop using this fan.

Comment:
I decided not to use yet, it is really nosy. Maybe with a speed fan controler in the future. Anyway the red light is great! when i tried

Comment:
Quality fan with red LEDs.

Pretty noisy but works great

I have just recently built a high end box and have install an additional 3 fans of this model. For the price the quality was excellent. They flow more air and are quieter then most any fans out there at there price. I agree the color could be a little brighter but the goal is for lots of cool air and as quiet as possible the color is just the bonus. I have 11 total fans in my case and these are as quiet as my larger slower fans in my CM HAF 932. I don't think you would be disappointed with them I WAS NOT!!

Comment:
good enough

Comment:
purchased 4. one is louder than the others, but i believe it was damaged in shipping. oh well, for 7.99 i can live with that.

Comment:
90cfm is great. It isnt the most quite fan but this fan definitely has the best noise to performance ratio.

Comment:
Other reviewers say it's quiet, but maybe I got the ugly stepsister. I will say that the LCD lighting is pretty cool though.

Comment:
Agreed, the led's aren't as bright as i expected. But this thing moves a ton of air i had a considerable temp drop using this fan.

Very nice fans, great build quality, push quite a bit of air so much so i replaced my cpu fan with one and it looks great to boot also the LED, although no the brightest, is very nice. These aren't without fault though, the mounting holes are not threaded. Maybe all fans come like that but i wasn't expecting it and i had to thread them myself. They are quite loud if you have more than 1, i bought 3 and now i am considering a fan controller or plugging them directly to my MB but they will only run at 1k rpm so a fan controller makes more sense.

I bought two of these for my server. Obviously, the LED's weren't that important to me, but it was the quietest and strongest fan I could find in this price range. I plugged one into the motherboard and another directly to the power supply. The one connected to the MB is SILENT!! I can't hear it at all! The one connected to the power supply, however, is rather loud. But it's running at absolute full speed, so that's why. Either way, it's not too important... the server lives in a closet under the stairs ;)

Comment:
decent fan.. thought the leds would be a lil bit brighter but oh well.

Comment:
im not sure if i should get this fan yet because i dont know the size of my case for my computer im getting in like 5 weeks

Comment:
Great Price, Very Quiet, Max air flow. actually pushes more air out then the fan that I replaced with it. Matches the other fans that came with my case perfectly. Bought it to replace another fan which came with my case that Lost a fin.

Comment:
Great Deal. Great Product. Great Price.

Extemely quiet (had to actually look at it to make sure it was spinning) and moves alot of air..Looks cool too (no pun intended)..I liked the first one so well that I bought bought another one..If I ever have the need for yet another fan, I WILL buy this Cooler Master R4-L2R-20CR-GP again !!!..I've had $25.00 fans that can't stack up against these ones..BUY IT..One thing about them though is that they're designed to run @ 100%, if you have a fan speed control and set them lower, they make a clicking noise and the LED blinks..But you really don't need to run them slower because they're so quiet.
