Fans are 3 pin, and I connected them to the mobo.
I configured the fan voltage to change based on temps (duh).
When its cool, voltage drops to a point where fans stop but RGB stays on, if it gets cooler, RGB turns off. I can even see RGB going dim step by step as mobo reduces the power to it.
Would this constant change harm the fans in any way?
Constantly switching power, and also sometimes it gets enough power to light the RGB, but not enough to turn the fans on.
