How to determine which potentiometer I need for this project?
I am building a laptop cooling pad with external power supply, and I would like to include a potentiometer so I could control the speed of the fan rotation. However, I am not sure about the resistance of the potentiometer.
I am using the adapter from an old HP printer. Here are the values: +16V, 500mA
And I am using the Cooler Master SickleFlow 120 fan. 12VDC, 0.35A
