Good afternoon guys.
I have 3 of this fans.

This are the yate loon 120mm blue led fans.
I want to power on/off the leds. How can i may do this?
If i cut the wires that goes directly to the leds from the 3 pin power, and then connect them directly to the switch it may work ?
Or i need a resistor in the middle, because i think the power for the leds, are the rail of 12V, and if each led works at 3V. --> 3v * 4 = 12V
So, if i need a resistor in the middle, what are the oms(voltage) of the resistor ?
Can someone help me?
