Does anyone have any hints/tips for reducing the temperature in a studio and bringing fresh air in? Given that we've 4 computers running, 5 monitors and other amps etc that all generate a fair amount of heat, the studio temperature often soars way up to 30 degrees! Opening the studio window does little to solve the problem - anyone any ideas for a cheap solution? Mobile air conditioners tend to be very noisy - normal desk fans don't really do much other than circulate the warm air. We really need some way to bring in fresh air quietly from outside, and possibly expel the hot air.
