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.

      That would be amazing thanks, I’ve barely worked with Arduino but I just ordered a starter kit to play around with and learn.

        I made a git repo with the schematic and yaml file for you, if you have any questions feel free to ask.
        I may not know the answer, but i’ll do my best to help.

        Thanks. 😀
        I had to use 4 different sources to make my project work.
        It wouldn’t be nice to force others to go trough the same amount of trouble when i already have the files.

    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.
