You can use whatever fan you want really. If you want to get a 5v fan, you can run it off your UBEC. If it's 12v, you can run it off your main batteries. However, running a 12v fan on a higher voltage will reduce its lifespan; the higher the voltage, the shorter its life since the fan circuits get warmer faster. Also, higher voltage will spin the fan faster. Some people put two identical fans in series to split the voltage. It really depends on your setup.

What voltage are you running? 12 cells, 14 cells, Ns lipo?
