You can do it much cheaper than you realize.
If you get a temp switch. Like one that runs the idiot light.
Stick it right in the head or thermostat neck where it belongs.
Get one with a setting like 210 degrees. Most switches operate in a range, like on, or ground at 210 degrees, and opens, or un grounds at 180.
If you ground the power relay with that, your fan will only run between those temps.
If you want it to stay on longer, interlock the relay, so once it comes on, it stays on until the power is killed like with the key switch.
Lots of very cool ways you can do it, ranging for less than $20 all the way up to hundreds.
I don't have an everco catalog anymore, but they had them listed out by settings, find the one you want and call up napa.
