Small computer fans draw very little power, I have some on my desk that draw less then 2 watts and if you combine them with a heat sink everything should stay cool and happy, you can also get solid state relays that can switch 100 amps, so switching 30 amps is not an issue, but I agree that a heat sink is a good idea.
