Don,
My 2000 C5 dual cooling fans use 30 Amp fuses each. What the Corvette does is run both fans in series together for low speed where each one would drop 6 Volts each so half speed, then high speed is with each connected independently to 12 volts. This is done through about 3 control relays.
I would suggest running each on its own 30 Amp fuse. Another way is if you have a amp meter that can read the amp draw when they are on then add about 25% for start up amp cussion. That would get you a real answer, then size to the nearest fuse value.
