« Amazingly quiet »

I purchased this fan to cool down my case, the bigger the fan the more spacing it has for the fan blades as opposed to its middle motor piece, the better the air flow, also the more blades the quieter it is since theres is less "choppiness" of the air being pulled in. I was surprised with how quiet and silky smooth this fan was, and will be purchasing another one soon, to replace the noisy 80mm fan i have at the front of my case.

I generally use my pc for heavy 3d graphics/games/modelling application and this fan helps keep it cool and quiet.

« Lovely fan, but invest in new screws »

The fan is wondeful, runs quiet and keeps everything nice and cool but dear LORD are those the worst screws I have ever dealt with. Ironically enough, they didn't fit the holes on my fan. However, the fan is worth it even if you do end up needing different screws

« Very nice Fan Cooler »

This is a very nice Fan. I like the fact that does very well its job, and also it is very silent while is working. Another plus is the intense blue color of its LEDs. The LED effect is nice. You can connect it directly to the motherboard or to the power supplie. All these features at a reasonable price.

« Cool looking and quiet. »

VERY easy to install. I bought this specifically because my old one sounded like a small plane and this did the trick. It's so quiet, I can even think while I'm working!

« good fan, but bad screws »

This fan is nice. Although it could be loud running at 100%, it is OK at 50% with settings in your bios.

Cons, worst screws ever!!! with 1 of them got all the way in with no issue. 2 were badly stripped, but I was able to get them in by pressing very hard. Last one got stripped so bad that it just stays half way in. Now I can even get them out at all.

Get your own screws from elsewhere if you can
