DELTA PFB0924DHE 24V 1.74A 9038 4-wire high air volume cooling fan.
Rated at 175 cfm at 24v.
Bet it is powerful enough at 20v, that a buck only converter could be the speed controller vs a buck boost which could feed it upto 33v.
Time.will tell.
My 24v papst and other 24v deltas have no issues being fed 30volts. No smoke at 33v either, but not worth chewing up another 0.5 amps for just 75 more rpm.
