The fan keeps what it promises: He's really very quiet and moved very much air. The color of the LEDs is a beautiful, rich blue. Definitely, one should note the installation depth of 3 cm! For me, it replaces the stock front fan from the Corsair Graphite 600T. By mounting depth can no longer use the front space for the hard drive cage. So if you want to run in this case more than 3 hard drives, the MegaFlow 200 is not suitable. 100% buy recommendation!
