Look great in my HAF Case. Love how they light up for a cool effect.

They look great in my HAF case!! The LED's don't overpower the other lighting, they're a nice compliment. They are a tad louder than the Yate Loons they replace, but being a gamer I don't notice it much. No issues with bearing problems that others are having.

Coolermaster generally makes excellent products. I've used their fans before and was satisfied with them, had no issues and they were long-lasting. I decided to buy two of these for my case. However, they really disappointed me.The red glow ended up being barely visible at all, it was almost useless. Also, they made this horrible bearing noise that drove me nuts. Maybe rubber mounts would help, but as it is, I eventually decided to stop using them, as I couldn't bear the noise any longer. There isn't any fan controller on the fan itself and I don't have one installed to connect them to, which might also have resolved the issue.Price was cheap and they provided good airflow, but I would never buy these again because of the noise issue.

Comment:
For a price match of around $5 it's hard to beat this for value. Not the best airflow or static pressure, and not the quietest, but definitely decent for case fans. These are great if you do a lot of builds and need cheap effective fans.The red LEDs are lovely, and for those clients that don't like them, well a simple snip or removal of the 'bridge' in the centre of the fan takes care of it.

For the money this is the best fan i have used, I bought lots of these from Coolermaster both very quiet and these over the years. Unlike my Antec try cool, kaze and a few others, all of my CoolersMs are still working, even the ones from 6 years ago even after years of water cooling abuse.They are a lil bit noisier than the old 900-1000rpms but als flow twice the air. Awesome.

I love them I'd purchase again.

For the price, you can't get a better case fan.

Comment:
great fan, great price, great performance. But not enough power to put on a radiator.

Comment:
I got this to go in my htpc and it works pretty good the only real complaint I have is that it's pretty loud. Aside from the noise and the LED which is to bright It keeps it cool

Comment:
I oredered 2 of these for my HAF 932 case.They were easy to install and are efficient, air-wise.Only downside is I was disappointed with the red light coming out of it which is very shy and doesn't show much.

I picked up three of these in order to match my black/red LED build I have. At first, they worked very well, and the majority of the noise created is just air being pushed, which isn't annoying at all. However, two of the three fans' bearings have already started making horrible rattling sounds whenever they spin. I know it's not because it's undervolted too, as I have them plugged in directly to the power supply. This may be due to the fact that sleeve bearings only work well if you have them installed vertically (I have them horizontal in my build), but still, just a few hours and it has already started dying is pretty lame.Overall, if you are looking for a high CFM exhaust/intake fan, this works REALLY well. However, be sure to mount them vertically, as these don't like being horizontal at all.

I have these in my NZXT vulcan as exhaust fans. They do a great job. Undervolt well, but dont push much air undervolted.

Comment:
Nice quality fan, nice price. I wish it had a stronger red glow for my Storm Scout case....

Comment:
Nice fans manufacturer advertises a 19 dba noise level I believe its a little more, but still a nice fan

Comment:
Got it locally to add to my CM Hyper 212+ for a push/pull config. Works well, although there is no PWM support. Quiet too. For the price, I cannot complain.

Comment:
I was a little disappointed in this fan. It looks good, but the noise is more than I expected. It is only 19 db where the original in the Coolermaster case is 17. The original is whisper quiet, but is 1200rpm where this is 2000. Guess that makes the difference in noise.

Comment:
Good all-around fan. Moves lots of air and isn't too loud either. Good airflow and low noise is exactly what I look for in a fan.A+

Comment:
Does a great job for a cheap price, push a nice amount of air and a fair noise level for a cheap fan.

Comment:
It's a fan, what can you say? Very quiet, I don't even hear them compared to the previous CM 120mm fans I had. 90CFM? Probably, they do push a lot of air, which you can feel.My only disappointment is in the brightness of the LED's. I should have known, they're red LED's, not that bright, go figure. Although the "glow" is not exactly what I was looking for, I can't knock the performance, and silence, of these fans. Red LED's are not all that bright, that's just how it is. I ordered a set of red CCFL's to make up for it.In the end, 5/5, I can't knock the fans for being red(I bought them), I'm very impressed by how quiet these fans are.***EDIT*** Seems my review for this fan is too short. What, it's a freakin fan!Anyhow, my dog's names are Sadie(youngest), Chelsea(oldest) and Maggie(middle). They all love these fans because they aren't too loud, and they don't steal their dog bisquits.Although I've tried to teach my two fans tricks, they have nothing on my dogs, who I've never taught ANY tricks.I hope that meets all the requirements of posting a review, LMFAO!

$5 fans. Win.LED. Win. (if you like that)Good CFM? Win.Overall this is a winner. Fits in my case and lights it up good.

Replaced my rear 120mm fan stock on the HAF 922. Works great, comes with mounting screws and a nice little 3 pin to molex adapter.

Comment:
Well, the fan works well. I loved it. I place it on the side chennal windows which looks more bloody. Awesome look~

Comment:
There's not much to say, its a fan. It runs pretty quiet and was pretty cheap. I have two of these running a push/pull on my cool it vantage and its great.

Comment:
Bought a few of these to replace my aging thermaltake 120s. So far so good, all remain quiet, the red LEDs are not overpowering light my previous ones were. They move air as advertised. Nothing to complain about.... yet.
