The fans need around 25% to 30% to get started. Once moving you can lower to around 20%. Maybe even lower. There is a feature that if you go from *off* to 20% it over powers the fans at 100% for a half second or so then lowers to 20%. This works great and jumpstarts them but if the first layer is 5% and the second layer is 10% it only jumps 0-5% and not 5-10% so the fans don't come on until around 30%.
by the way the % represents the duty cycle. So if the fan is at 50% that means it is at full power/voltage for half the time and off the other half the time. The cycle is 5 to 10 times per second. Same method for setting power to the heater in the nozzle.

It also differs between fans. Some come on earlier than others.
