Hello all, I am just looking for the most quiet 12v case fane I can find for my 2990DX, it does has the fan kit on the rear heatsink , but would like to install a fan on the top of my case to keep the driver and and the rest of the inside cool, but looking not to add much noise as I really have enough from other things....any suggestions? or can I add a resister to slow a fan dow for less noise?
