HELP: which controller /temp sensor

[stopdrpnro]

ok this is a weird application and wasn't really sure where to put the topic but i was hoping u guys could help me out. i'm trying to build a car amplifier rack and i had this great idea to have the fans on it temperature controlled. can u guys recomend a cheap auto fan controler/ temp senor that will run about 4 92mm fans and be ok with reciving 14.4v when the car is on ?

Idea!
You could just try to get a thermo-rheostat. It's like a resistor that changes its resistance with the ambient temperature. All you have to do is to find one that suit your needs... The higher temperature the lower resistance.

well they have tons of thee thigns for the computers, which run on 12v just like cars. so it shouldn't be a porblem gettin a computer 1 and just hoook everything up in the car. the problem isn't finding 1 i'm just looking for recomendations.
