Question about fan controllers

post #1 of 2
Thread Starter 
I have a Rheosmart 6, attached to 4 120mm fans each on separate channels. I think the rheosmart is rated from 0~12v on the controller. I remember reading somewhere if a controller is set to supply a low voltage, the components can heat up because it's holding on to the voltage that it's not sending to the fans? Well basically my question is, is it safe for me to keep my fans at say 50% or even turn them off without having to worry about something catching on fire?

yes there are heatsinks on the controller that will handle the heat. I have the same fan controller and I sometimes have them on manual mode where i lower the fan speed to cut sound down. They're made to be used the way you indicated safely.
