Is it possible to use a raspberry pi to control case fan and rgb?

[Strigon]

Had an idea of using a raspberry pi to control both case fans pwm and rgb. Let the raspberry pi be independent from the pc. 

[Levent]

Yes.

You will need a +12 V power supply for the fans.

Also the raspberry pi's GPIO output voltage is 3.3 V, while your fans run with 5 V PWM, so you need a transistor to amplify the 3.3V to 5 V.

The PWM runs with 25 kHz. The Raspberry Pi should be able to do that.

Yes totally possible but you will need a 12v adapter and a board to plug them in to.

 

Most people just do this stuff with an adruino because it's cheaper.
