You mention it's moving more than enough air. Would running it at 50% or x%
duty cycle be effective enough? One minute on, one minute off. A simple
circuit with a relay could do that, there are even some ready to go timer
relays. Also you could hook up a thermostat with some hysteresis to have it
turn off and cool when it hits a temperature set point.
