[QUOTE="dvader, post: 2502439, member: 101429"] Did you try to run a fan with just 12V, I mean no third wire? If the UPS doesn't complain about the absence of rotor signal, then you should be good. If it does need a signal, (all it would need is a voltage) use very high resisters in ratio and solder them between Ground and 12 v to get the desired drop on the third pin. Since the resister value would be very very high, current would be almost zero, so no damage to any components. However, I do think that the fan will work with just two wires. [/QUOTE]
