MO420
PWM Case
Magnetic PWM Motor-Control Case
Big big Fan
I use some fans inside my server rack and not always had the possibility to be inr each for a PWM controller to adjust the speed for the fan. So I created this small case to hold a standard PWM controller to control any fan or motor. I attached a magnet to the buttom so I can mount it anyhwere inside my server rack for optimal reach.
Assembly Parts:
