Dual control circuit relay set up? <-- probably not the correct wording :(

Hey guys, I was wondering how I can get around this, any help is appreciated.

I am using USB and Trigger outs on my devices to control fans and lighting in my custom built entertainment center using simple 2 channel relay boards. This is good enough when there is just one device per slot in the cabinet, however I have at least one that will house two devices. Each cabinet slot/shelf/rack has just one fan and one light and I'm trying to avoid adding a second fan to the slot with two devices. My question is, how do I wire up the fan so that it turns on when any of the two devices is powered on, but doesn't get fried if both devices are on at the same time.
