The 9 fans are on 3 360 rads, and should all have the same speed.
I found many speed controllers, but all of them seem to have 5 channels, and not support a high output per channel.
Ideally, I would like the mainboard's CPU fan header to control the speed of all 9 fans.
If I can't find anything, I will make a custom PCB to do that (I'm good with electronics). I wanted to ask first if someone knows a trick for this use case?
