So I’ve got a couple of Mini PC’s and a ODROID H4+ as a NAS, all just standing on my desk at the moment.

I’m going to build them into a 10" Rack and I’d like to have a good cooling solution.

My idea is to buy something like this https://www.alternate.nl/Noctua/NA-FH1-fancontroller/html/product/1917195 And wire it up with a ESP32 board and temperature probes, so that I can connect it all to a dashboard in Home Assistant.

Any advice on this project, or better alternatives would be appreciated.

    I actually have a working’ish prototype of this project laying on my table right now.
    It’s a 120mm noctua fan being controlled by pwm i relation to the temperature. It also has an oled screen to show temp and fan speed. All controlled trough home assistant via esphome.
    I say working’ish because the temp sensor i’m using (dht11) is unreliable and is messing up half the time, so i’m looking into buying a DS18B20 instead.
    I’d be happy to share schematics and code if you’d like it.

    If you want to do this as an ESP project anyway, you don’t need the extra controller.

    Fans take a simple PWM signal, which your ESP (or even one of the smallest Arduinos) can create easily.
