my fridge fans..
My little cube fan died. I really didn't feel like buying another for $16 just to have it die a year later. I built this for about $10 plus my time. It's held in place via velcro and ground clips. I had the wire, tin and fuse holder. Power is fed from the light switch. They only use about .28 A total. I was going to put a rheostat in the circuit to reduce fan speed, but determined it isn't necessary.
The only change I may make is to install fan guards to prevent anything from and jamming the fans.
