unless you live in a damp, cold climate, evaporative cooling -when correctly dimensioned- will outperform any radiator setup. Because the best you can achieve with radiators is ambient, while evap can actually drop below ambient.
eg Nevada desert
Ambient Temp 30°C , Ambient Humidity 0 - 5% , which results in a dew point between -32°C & -13°C
With an Evap sized & efficiency at 85% => temp drop (air/water) to +/- 15°C (wet bulb temp)
There is a sliding scale with an optimal range, the kicker being what is the dewpoint?
The hotter & dryer the environment, the lower the dewpoint, the "better" evap cooling works before it either saturates the ambient (room) or before the maximum rate of vaporisation of water per sec is reached.
keywords: google, wikipedia, cooling towers, evaporative cooling, swamp coolers , etc , you can get lost in the subject for days on end
it is almost impossible to achieve 85% efficiency with a (self-build) bong cooler, you need to use the "industrial design" & swamp coolers.
Now, if these things weren't so damn bulky & cumbersome Edited by RnRollie - 3/4/14 at 2:30pm
