I want to put some devices like NVR, modem, router, et cetera in a closet.
I’m having an electrician install a 240v AC power socket in the closet.
I’d like to cut a hole in the top of the closet through to the ceiling cavity for an exhaust fan.
I’m hoping to decommission my home server so I’d like to avoid having to run exhaust fans from a computer / PC power supply.
With all that in mind, I’m looking for one or more devices that will allow me to run two PWM case fans with thermostat from 240v.
If you don’t mind playing around with a Raspberry Pi and a few jumper cable, have a look at my repo. Half a year ago, I built a fan controller to regulate temperature and air flow in my server cabinet with 5V PWM fans. It is not finished and rough but it works. After moving in a few months, I will have the time to work more on it.
If you have questions, feel free to DM me :)
