4 wired fan 5V 0.32A, which resistor to use for 3V?
Because of a problem, my macbook air fan is runing constantly at 100% (because the temp sensor is broken).
Let's say I want it to run at 50% permanently, which resistor should I use and where should I solder it.
I have 4 cables, from left to right:
Black - Grey - Green - Brown/Orange
This is what I've measured (assuming black one is ground)
Black - Grey: 5V
Black - Green: 3.3V
Black - Brown: 5V
What's on the fan:
Thanks in advance for your help.
