@martinnyhc said in Controlling two fans at the same time:
I found out that PWM is not working properly when connecting two fans in parallel to one port. I have two electronics bay fans, would like to connect them seperately to two ports but it would be very nice if I still can control them parellel. Is that anyhow possible?
Thx.
2-wire fans are not designed to work with PWM. It's a miracle that so many of them do.
If you connect two dissimilar fans in parallel, then I am not surprised of they behave oddly when you PWM them. But if they are identical fans, I would expect a parallel connection to work.
