I have got a car radiator fan 12v (cant find the specs for it) and a Dell 7000814 psu.
I have taken my 12v supply off of the rails in the psu 12v at 57.3A max the issue is that it is switching itself into safety mode unless i get the motor up to speed off of a battery before switching it on, i am looking at the following pwm: http://www.ebay.co.uk/itm/162179562778 as im looking to control the speed of the motor but was wondering if this will also reduce the start ampage so i can start off of the psu or if i need some sort of capacitor or resistor to reduce startup ampage on the motor? thanks in advance
