Comment:
great fan. light looks awesome not too bright, and moves a lot of air. also doesnt take a fat chunk out of your wallet. got 4 of these 2 green and 2 blue and i would highly recommend them to a friend.

For a fan that spins at two,000rpm it confident appears quiet. It's good now that I don't have to spin my Antec fan on High all the time. Computer noise has gone down and cooling has become more efficient. The 4 screw holes are not threaded. I don't get it. I had to go get a couple nuts... Some 3cm screws would have been nice to have as well. I liked the LED lights more than I believed so I switched this fan to the rear. Good fan.

Quiet in fact bought this to replace my ULTRA KAZE item number N82E16835185054. My Ultra Kaze functions fine but others employing this comp had been annoyed by its noise this fan was the ideal solution quiet and gets the cooling carried out! Blue LEDs are not over powering they are just the correct amount. NONE! Purchase IT!! if your seeking for cooling energy, excellent product, and accent lighting buy this item you wont go incorrect ive had it for five months and i anticipate it to final a really lengthy time. Never ever had an matter with it at all.

Top quality Coolermaster product!

A price you can't beat for a stable fan that doesn't run with excessive noise. The noise you do hear is smooth and clean. The LED color adds a nice effect too. I highly recommend.

Rapidly, blue, and really My old one broke although placing in this new a single :/ Barely touched the blade and it fell apart.

I like this smaller fan. It's nicely made and has good air exchange. I am not even using this on a PC, I'm using it to circulate air in hatchs and closets on my boat.

Silent, makes the case have some light, a reasonable price, i have to say this is a good product.

Comment:

Durable as hell and has lasted meyears cooling my case. Bought it to add color to the rear of my case

Comment:
Great fan! Moves a lot of air! Hardly any noise in my case. Just had to make a bit of space with washers between the fan and case to keep it from rubbing in my particular setup. Best bang for your buck fan!

Comment:

The fans appear nice, worked correct off the bat and do push a great bit of air. Cooler master's QC was not undertaking their job, or just suck anyways. I purchased two of these fans, and whilst one of them had color matching LED's (all four are dark navy blue), the other DID NOTƑ dark blue, the other 3 light). the only reason i chose to purchase lighted fans was to have a single color in the front of my case, not two various colors coming from 1 fan. get your QC together CM.-two eggs for that. I will not purchase from Cooler Master again due to the lack of quality control here. If both fans had arrived with matching led's then it could be various, but they didn't.Can't comment on lengthy term durability as Ive only had them about a month.....all that aside newegg rocks for pretty much almost everything.

Sleak design, good frosted black translucent plastic. This thing is moving some severe air, and was great price. LEDs aren't as bright as my other fan. (Guess I'll have to purchase a 2nd one to match)

Comment:
This is an awesome fan, the led looks amazing in the dark, so I hope you dont sleep next to your computer! Its quiet, and does its job well, considering buying 2 more.

Comment:
They have wonderful color and move A TON of air. They lowered my GPU temps by virtually 10c! They are A great deal louder than advertised. Under standard load, they are the loudest part of my program. I had to purchase a fan controller to deal with it louder than my Crossfired 5770's

Comment:
Moves air on 4 of them, 1 makes a lot more noise than the others ... I'm fine I can lessen the rpm with my controller.Pain IN TH3 455 NO PRE DRILLED HOLEI had to drill them by myself, -2 eggs Okay for the value.

Comment:
These are great fans! I recently bought my second one of these, and if I ever needed to buy more fans these would be my first choice.For the cost they can't be beat! Great airflow, quiet operation, and really low price. If you don't mind the LED lighting, its a great buy.If you need to push a lot of air, get a few of these!

Comment:
Love it. Quiet and moves alot of air. Mild blue. none

Comment:
Simple install, comes with the screws you will need. I have a Cooler Master case so this fan was great. Runs pretty quiet. Dropped my temp from 52c to 46c. I am about to order two additional to replace the stock fans. The LED is vibrant and looks fantastic, matches the blue power light that comes stock in the case. The only con I can assume of is that the screw holes were not threaded and that is the ONLY con. I purchased a p.c.i card fan and it was garbage. Really produced the temp in my case hotter. I purchased this and installed it with ease! Excellent item, can't say it adequate!

Comment:
Great fan for cases and provides really good air-flow. Blue LED looks really nice in the dark. Bought 2 of these and I would suggest hooking them up to fan controllers. If it is spinning at max (2000rpms) it gets quite loud.

Comment:
When price matched, these are a great value. They push quite a bit of air and are very clean looking. I used them to replace dying Antec tri-cools and they do their job well. If you like the look of LEDs and don't mind a bit of noise, these are perfect for you.

Comment:
I have 3 of those in my case, they really help. What matters is where you place them in the case.

Comment:
cant really complain lol does what i need it to, blue light looks cool in the dark

These fans are very quiet, the blue led lights look very nice with my black fractal r3 case. Easy to install, had directional arrows on them which was nice no guessing on installation
