Why do you want to make a room filled with electronic equipment more humid?
I think that's the dumbest thing I've ever read...
LOL, you have never run a datacenter have you....the humidity in a datacenter is typically kept over %50 to cut down on the potential of static discharge. At %12 the potential for static discharge is huge. I don't want the air to be super humid....It definitely SHOULD be higher than %12.
