Hi @karenthmelissagarcia

To check the fan speed, you can use a potentiometer and a digital multimeter (DMM) in a simple circuit.

:wrench: Here’s how:

  1. Use a Potentiometer

    • Connect the potentiometer in series with the fan and power supply.
    • Turning the potentiometer knob changes the voltage going to the fan, which controls the speed.

  2. Measure Voltage with a DMM

    • Set your DMM to DC voltage mode.
    • Place the probes across the fan terminals.
    • As you turn the potentiometer, watch the voltage change.
    • Higher voltage = faster fan speed, lower voltage = slower speed.

:pushpin: Note: This gives you indirect control and measurement of fan speed.
If you need the exact RPM, you’ll need a tachometer or a fan with a speed sensor wire (usually yellow or blue in PC fans).
