Can we do some thing like these aftermarket product?
It will have different construct but as long as it can work, it should be ok.
We will need 3 parts:
1) Temperature sensor & feed back. (Or we can use time control where it switch on for 1 minute and off for 1/2 hour "this should be easier")
2) Power supply unit(PWM) with battery check cut off.
3) Air con blower trigger.
I saw a fan speed control unit in aPC power supply box. it has a thermocouple and it works when it is hot and shuts off when it is cool.
Look for PC power supply with the label "Noise killer" because it is quite when it does not move (when not hot lar).. :)
