I have an Enlight case and a 60mm Vantec case fan, mounted on the rear, adjacent to my Slot A Athlon. My computer is MUCH quieter when the case fan is disabled, and I wondered why. I opened up the case, unmounted the fan from the exhaust grill (which is really a grid of holes drilled in the sheet metal), and noticed that the fan was amazingly quiet. Only when mounted does the fan became noisy (whooshing noise). The cause? Air turbulence. In fact, I noticed by placing tissue paper behind the fan when mounted, the air is moving in BOTH directions behind the fan. Pull the fan away a couple of inches, and the air is moving in one direction only.
So, it seems the fan is too powerful for the exhaust holes, with as much air being pushed back as is being exhuasted. Certainly, this is reducing the effectiveness of the fan. In addition, it is causing the fan to be much noiser than a properly matched fan/exhaust grill combo.
Any suggestions? Should I drill more holes? Simply cut out the swiss cheese circle altogher? Get a slower, less powerful case fan (where?)
