Here is a Silver and Blue 80mm, and as you see the finish is immaculate. The blades have a slight curve to them which reduces the noise of the air exiting from the end of the blades, which is where most of the noise generated from fans comes from. The 80mm fans are rated at 20.3 dBA which is almost silent, and when I powered them up I can attest to the fact that you can barely hear them.
