I used regular computer muffin fans running off a 12 volt power supply. I do get corrosion where the wire is soldered to the motor connections. I will have try a dab of grease or something to minimize the corrosion. The top of my tank is open with 3 fans running inside. Mister comes on for 15 minutes about 6 times a day. Originally I salvaged fans from old computers but now I just buy a couple from computer parts store whenever I'm low (they last at least a year without any corrosion proofing). More air movement has been critical in preventing rot.
