hey guys, i need to install new fans to my pc, i have already connected two fans to the chassis fan connectors in my mobo, but there's no other chssis fan connections in my mobo, so im going to connect them through the molex connection.

i want to buy a potiometer so i can manualy control the extra two fans,specs of fans:
2 X 12cm DC brushless fans, 0.35Amps.

i need to connect two fans with two potentiometer, whats the best maximum ohm and watt for the potentiometers, i want to be able to completely turn off the fans, and make them run at full speed with the potentiometer. i think potentiometer's watt should be higher than 0.42 (0.35*12), also, i think ohm should be close to 35ohm, where can i found this potentiometer, i have searched in ebay, but couldn't find a potentiometer close to 35ohm and above 4.2watt.

here's a diagram i made :D
