Generally speaking, for quiet air movement you want large diameter, slow
moving fans. It's the smaller, high-speed fans that make lots of noise.
I'd use a 120mm fan for what you want to do. I think a temperature switch
might be a little tough to do, and you'd have to put up with it cycling on
and off. One relatively easy thing would be to wire in a potentiometer
(aka "pot"). Basically a rheostat that you can dial up or down the fan
speed to your liking. Frigid could definitely help you with that. They
have different kinds of pots for AC vs. DC power, and the voltage range
required, but they can help you find the right one. You also may need a
couple of fans if you find you need to drop the fan speed significantly to
achive your noise level goal.
