Ok, I tried to save some money and upgrade the noisy fan in my old Deer 300 W PSU with an Antec 80mm thermal control Smartfan. The fan that was in the PSU is a Power Logic 12V 0.14A 80mm fan. When I started the PSU with the Antec installed, the fan wouldn't spin. I spliced and soldered the 2 pin connector from the old fan to the Antec (red/red and blk/blk). I thought maybe the wiring was bad, and tested the Antec with a 9V transistor battery and it works fine, so it starts at 9V. Why doesn't the fan spin when connected to the PSU board? I noticed that it start and spins for a second or so after the PSU power switch is turned off... Does it maybe need more amps to start than the board gives? Amp rating of the Antec is from 0.109 to 0.225 as it spins from 1600 to 2900 rpm. Any thoughts on why the fan won't spin???
