Power resistor help (novice)
Posted: Tue Feb 27, 2018 11:05 pm
Hi.
i have 10 x 12v 0.14amp computer fans i need to quieten down.
What I want to do is splice 1 of their molex cables 12v line to include a resistor to decrease the voltage from 12 volts down to 9v.
basically its 10 fans plugged in together making a total of 1.4 Amps @ 12 volts.
I was thinking of using a 2 amp resistor but I do not know what kind of resistor or value to use.
Can someone tell me please and tell me if there's a calculator for this kind of thing.
Thanks.
