Aerocool Shark 140

Another fan sponsored by Seeing Red...thanks!!

This fan seems to be leading the pack at the higher RPM area and only about average at low speeds. Fortunately there isn't any blade resonance that the yates had problems with at high speeds, although there was one small resonance bump at 11V. Overall the best fan so far at high speeds from both a noise quality and noise level perspective of the fans tested so far. It does consume a fair amount of power though (4 watts). Regarding CFM/RPM it is very good, gaining almost a 200RPM lead over the 7 bladed yate at high speeds.

So far, it seems like a higher number of blades is a good thing. The thermalright leads the slow speeds and this one for high speeds. I did notice a small amount of rubbing noise at very low volts, but that seemed to go away at medium to high.
