    Its a fan... It spins... Not much to say.

    Great fans for the price for general use inside a case, extremely loud at high RPMs, for example running off a 12v 3pin molex supply. LED's decent enough, nut super bright or anything.

    Does its job well, provides good airflow, and looks pretty good as well. However, one of the fans I have will sometimes make a really fast ticking sound. Still don't know why.

    Keeps everything cool, and it is not deafening to listen to. The red LED lights are nice to stare at at 4 in the morning, too.

    Gonna have to knock a star off, though, since these fans are somewhat noisy. These had me so worried that something was wrong that I had to open up my computer just to be sure that their noise was not coming from anything else in my build.

    Awesome fans, fairly quite, adjustable speed, very bright.

    I actually have the blue ones, not the red ones. Quiet, moves some air. No complaints.

    The connecting cable is very short so had to flip with the upper front fan for better cable management, also clear blades on the fan would have enhanced the LED effect . Honestly though, it was cheap and it works fine.

    Works as advertised. Z's house is pretty noisy, so I don't think he'll complain about fan noise if there's any.

    LEDs are quite dim.

    This fan pushes a lot of air out of my case. I hardly notice that it is on. I will be picking up another one to replace the one that came with my case.
