A quick solution might be those spayers that they sell to sunbathers to 
keep cool.  A pump sprays an extremely fine mist, that is really quite cold.

Would a 'mist-assist' cooling system work better with a long plenum and 
thick radiator?  My thinking is that the extra distance would give the 
water sufficient time to evaporate completely.
