Thanks for that idea. The fan is only 1.44 watts at 12v.
I noticed that the Fibaro RGBW controller is using PWM outputs. Perhaps if I got a fan that has a PWM input I could use that? Their manual says it works with fans, but doesn’t give any further detail and I can’t find anything online where anyone has actually used it for a fan control. I also read a lot about how the PWM frequency can cause fan humming, and I certainly don’t want any extra noise out of this.
