I run them continuously. I'd have to check if there is a difference on or off in terms of vibration. I suspect no effect. But there is certainly a softening effect from mirrors being not at ambient and also perhaps from a boundary layer forming on the mirror surface.
I find if the mirror is 1C different focus will be soft and it sharpens considerably when the mirror and air per the temp sensor is .1C different.
