Fan size is:
6 x 6 x 1.5 cm / 2.4″ x 2.4″ x 0.6
1800 ± 10% RPM;Air Flow : 60CFM;Noise : 23 db
The fans were $6.73 for the pair (amazon), scrap aluminum and wire, along with $3.99 for the lighted rocker switch.
I tapped into 12 volt power behind the refrigerator.
I try to label new wires for future reference, like next week when I cannot remember where this wire goes.
The on and off rocker switch is down on the floor.
The switch puts off so much light I covered the front face of the switch with black electrical tape
Here is the switch on
