Cooling suggestions (fan)

The downfall of people going with electric usually comes down to poor wiring techniques. If you use an electric fan(s) don't go with any type of electronic controller
use a simple capillary type switch with good quality Bosch type relays. Also have a
backup jumper circuit to bypass any controls to activate 12v directly to fan(s). Dual
fans can cover more surface area and also provide backup if one fails. Mechanical
fan is more reliable but leaves "free" power on the table.
