You don’t hook the fan up to the Thermostat, it runs 24/7. Only the heat tape is hooked up to the Thermostat.

What i did that require nothing special is Jumped a computer power supply.

Buy any cheap 20-40$ power supply. Take the ATX 20/24 pin power wire. Take a Paper Clip and push it in slot on the plug in black(ground) and then Green(jump power).

This will then once the power switch is turned on will give all the 4 pin molex plugs full power. All thats left is just plug them into the fans. This option is safer and better than splicing dc plugs and wiring single fans to them. My setup will run 400watts worth of fans
