Pros: Blue fan blades, sturdy construction, moves a ton of air, silent, fluid motion, self lubricating
Cons: It wouldn't marry me
It is rated at 80 CFM but feels like it pushes eve more air than that. It lowered my overall case temp by about 3 degrees and is nearly silent at full speed. I cannot hear it spin up nor can I tell a difference in sound levels over the other fans. It has a self-lubricating mechanism which is nice so that the fan always spins fluidly. Dust and water proof only make it that much more appealing. With Gelid you always get what you pay for and this fan is worth every penny. I plan on getting 2 more, one for the bottom intake for my case and one to mount in the 5.25 bay.
