I don't know the exact answer to your question but the test setup I saw it wasn't the power consumption but the current required for the rapid spool time that was the issue. At 12v the current would easily hit 1400A, about the same as a modern land cruiser starter motor, but it will hit 1400A every time you want it to spool quickly whereas a starter motor is once for a few seconds then it can cool down. At 48v the current drops to about 300A and it spools quicker. In both set ups the current can be electronically controlled but the trade off is an increase in spool time. A larger flow needs a bigger fan which means more inertia and either higher current to spool or more lag if you limit the current. There's no free ride as the saying goes... 48v was chosen as it's in use by military applications already and this was one of the target markets.
