Computer fan speed controller. any wants?

[banditpowdercoat]

I am placing an electronics order to make some 12v computer fan variable temp/speed controllers. I am wondering if there would be interest? As it sits, you would have to supply a power supply and the fans. The controller will be housed in a plastic box with tangs to be able to screw to the inside of stands, or canopy's, with a temperature adjust dial. Instead of just a ON/OFF style controller, this will vary the fan speed. As temp increases, so will fan speed. Should be able to control up to 25W+/- 5w worth of fan's.

Wondering if there is much interest? Price would be $25-35 range

I got enough supplies for 10 controllers on order
