MetkuMods reviewed the blue ledded Coolermaster Neon Led Fan :
This fan looks really cool, it is quiet and pushes enough air to cool your system down. One thing to remember with this (basically all led fans) fan is that you shouldn't use it with baybus or rheobus. By lowering the voltage you will make the leds dimmer and if you lower it enough they will not light up at all. It is a good thing with this fan that is so silent that you can run it with full 12 volts and not get so much noise. As you can see from the images above, leds in this fan are easily bright enough to give really powerfull effect. This is definitely something that you have to have for your case if you have case window installed.
