Fan moves just enough air that's about it. And price is good for what i need. Blue neon light is a nice touch. recommend it.

The fan keeps the PC running cool, the lights are a great touch as well.

Pushs alot of air, lights are not too bright but it is a very nice color of blue,

Pros: Great fan. MOves a ton of air. Nice blue LED's. Cons: Poor design. When put upside down in my case the fan vibrates a ridiculous amount. When standing, the fan is usually fine. I would still recommend this fan to others, as the vibration isn't that bad.

Runs Great!

Well, it works as stated. Cool and quiet. Only downfall is the screw hole were not predrilled. The screws went in very tight(which is good), but i would recommend running a screw in and out of all the holes first. Then mount the fan.

Does it job tremendously well.

This thing moves a LOT of air. Seriously. It was kind of hard to work on the system with this thing running. It was blowing my hair around and making my eyes tear up. It was sort of like staring into a window fan. If you need a powerful 120mm fan, this is it. It's a bit loud, but a fan controller will take care of that. Even running at 5v, it moves more air than most of the case fans that come with new cases (just an opinion, not fact).

Had one 120 in on the side and one 120 out on the back. bought two of these. replaced the 120 out (moved to different rig) and added one of these on the front in, everything dropped about 3(loaded)-5(no-load)C. very quiet too. Great little fans definitely will buy again for next build.

Comment:
have fans installed in 932 case. keep my hardware cool.

I just bought a NZXT case with a blue led fan in the plexiglass side and decided I needed one more fan. Very quite and keeps my processor at least 5 degrees cooler, plus it looks cool.

These loo great, work great and plug into the motherboard. I over clock so its great to turn these up or down base on demand. All the way up you can hear them but I use a head set when gaming so no problem there and when temp drops the fans slow and are silent. (motherboard controled)

Comment:
The fan was too big for the back exaust port so i used a small hole saw and made a grid and mounted it in the removable side panel.points right at the memory bank which was getting a bit to warm.works great memory runs cool and it helps the whole computer run cool.if anybody wants to copy my idea a drill bit could also be used

Comment:
Bought two of these for a new PC build. They have been working flawlessly for 4 months. The LED's are nice; however, I have a clear side panel, and I thought these would light it up more than they actually do.

At 90 cfm and low noise, this is an excellent alternative to the fancy fans that try to change their speed depending on temperature. This fan is quiet enough you just let it run full blast. Lower noise and dropped case temp 5-8C.

Comment:
5-stars all over. They are a bit loud but not irritatingly so. Also, seeing blue stream out of my case from every direction just looks awesome. Oh, and the fans work as-promised.

Comment:
The LED isnt bright but other than that it works great.

I purchased three of these case fans for a new computer I was building. Two of the fans seem to have a noise coming from the bearing area. I had to replace them right away. Because the price of these items is so low it's not worth the trouble to try for warranty. It's easier to replace them and write them off as a poor purchase.

Comment:
I bought this fan for my new build and its great, i find it a little loud, but thats fine considering how much air it pushes. Ya its a little on the loud side, but it will keep your case very cool.

Comment:
Using this to cool an aquarium light and it works great. Extremely quiet. They run for 9 hours a day every day and are working great.

Comment:
This fan pushes .. pulls a lot of air! For the people complaining about the noise, I had the same problem. If it is mounted against a honeycomb grill on the intake side, it will make a high pitch squealing noise like a airplane. To fix this you will need to back it off at least a quarter of an inch. If you are using it to exhaust, it will be pretty quiet. Don't forget at regular speed they are at 2000 rpm, would definitely suggest a fan speed controller if you are having problems with the noise. Drawback is that the LEDs will dim a little.

I wasn't expecting the size of this fan and the fact that the ports on the new case were much smaller than the fan. couldn't hook it up on the side like I wanted and the fan overlaps the back fan port by an inch or so, but it moves air into the case like nobody's business!!! great little fan, hope I get long use out of it. if get a couple years or so out of it will replace with another if available. considering buying more of them anyway to other puters I might be able to get running here at home.
