How close is that 120mm fan to the side of the case when you use that mount? What are the acoustics like? I'm sure I've read in this thread somewhere that having the fan too close to the case creates additional noise. I ask because I've been wondering how a 120mm case mounted compares to a 92mm heatsink mounted, assuming the same heatsink in both. If the 120mm case mounted performs better, but sounds louder, I can disregard it immediately.
