Since there are fewer fans, how does this affect the Mac Pro’s noise level? Is it loud?
The Quad G5 used nine fans and a liquid cooling apparatus. The Mac Pro, on the other hand, has only four fans and no liquid cooling—that should give some indication of the amount of cooling needed. We didn’t notice any loud noise coming from Apple’s demo Mac Pro, and Apple told us that the fans’ dynamic range is very small, meaning you shouldn’t experience large fan-noise spikes as with the Power Mac G5.
