I came here because I wanted to ask a question...

My computer room is approx 2x2x2 meters, and has no windows. During the recent good weather we had, the temperature in this room was getting up to 35 degrees, and was too hot for my computer, which would crash due to "thermal event". A fan pointing directly at the comp deals with this, but it's still uncomfortable sitting in 35 degrees. I can't afford a AC unit, so I'm left wondering how much I can cool this room using evaporation methods.

Are there any tables I can refer to that will tell me how much evaporation needs to take place for a set target in reduction in temperature? Obviously I know humidity is an important factor, I might be able to borrow a dehumidifier through the summer so that might be controllable despite the lack of ventilation. So... at 50% RH and 35 degrees celcius in 8 cubic meters of air, can I get a reduction of 10 degrees by evaporation alone?
