Reply to "How to" DJ in a hot, sweaty venue?

A particular place that I play at pretty often away at college is a sweatbox/sauna whenever the parties are thrown. Its in a big house/apartment, and this is really only a problem before the winter, while its still pretty hot outside.

Usually when I DJ there, i have 1 fan on my laptop, and 1 fan on my s4, but I'm starting to get nervous especially about the laptop (I have a warranty on the s4, and my laptop i have a backup through Time Machine, I just don't have the money to buy a new Macbook if it breaks)

When I used to use a Numark Mixdeck last year, the jog wheels (touch sensitive) would stop working when it got too 'muggy' and moist. The laptop was always alright, but does anyone have any good ways to be safe in a hot/humid party climate? Share!
