Making Wled working with fans pc case through Signal RGB integration

Questions
1

Hello everyone,
I’m new to Wled so i want to be carefull with the project i’m about to make.
I want a way to control all my fans individually in my computer fans through Signal RGB.
The final goal is to make 1 led illuminate and the light goes through all the lights one by one.

  1. first problem i’ve only got 3 channel into my motherboard and i’ve got a lot of fans (4 in total + 1argb strip integrated in the case), using a splitter can’t create the effect i’m trying to make
  2. using a real controller (not a HUB that’s working like splitter) like the Razer could solve the problem, but i can’t find any of it, not in sale anymore…
  3. here comes my last solution i want to use an esp 8266 to control 3 of the fans individually and then through the Wled integration in Signal RGB sync everything up.

So first is that something that you think is possible.
In cable management purpose do you think that i can power my ESP8266 with the ARGB header in my motherboard and use some WAGO’s connector to distribute the +5V and GND to led FANS ?
Then get my DATA output of the ESP to complete the wiring of the LED fans.
Here’s a little drawing.

Isn’t that risky for the motherboard ? I heard somewhere that the ARGB header can provide something like 3-5 amps, to power the ESP and something like 70 leds i think it’s enough

Thanks for your help and sorry for my terrible english it’s not my native.

That would work but I would not take power from the motherboard header, use a molex cable from the PSU instead. And preferably use an ESP32, not an 8266.

I’ve cut an old 3pin argb header and wire it to the WAGO and it seems to work pretty fine but i agree with the molex i will change that soon, why an ESP32 is better than an ESP8266 ? i only need 3 data port so it’s ok i think

It’s OK with a small number of leds. Multi-strip Support - WLED Project
Was just saying that if you still had to buy your board then it’s better to go with esp32, not worth buying 8266’s anymore these days.

I’ve got something like 60 LEDs so i think it’s ok but thanks for the advice and the help :grin:
