I have seen those computer fans used in a number of applications. What do you use to power them? I would like to integrate a couple into a tank canopy to cool my lights.

An AC to DC adapter, usually 12VDC but anything from 6-14 will work but fan speed varies with voltage. The adapters with an adjustable output in that range are nice so you can adjust the fan speed as needed or until you get an acceptable noise level.
