Try www.pcpowerandcooling.com 20db fans. You will need to go to Radio Shack and buy a AC to Dc convertor that can power as many fans as you need. The one I purchased cost 29.99 and runs 4 fans with no problem. The fans are 8.00 each shipping included. Simply plug in the converter and run the red wire from the fan to the red input on the convertor and do the same with the black wires. You will need to splice some wire to each side to make it the correct length for your installation.
