78hz pwm signal works. 30hz and below does not work.

fan pulls 25 amps in free air ramps up in speed and current

3.25" thick 15" dia

pmw signal to ground fan shuts off over 98% duty

Check fan speed chart

Don't know housing size of c7 but have one on back order.
I a have fan from 2015 c7 z06 but no shroud. car fire damaged it.

when it gets a speed signal it orientates it's self then slowly ramps up.
some times it goes backwards to orientate.

Looks nice.. hopefully it works as well.  I'm sure the electronics are really similar to a 4 wire CPU fan.. easy to control!
