Actually they have ones that use 3W LEDs as well

Also you could use a peltier system and regulate the current with a simple thermo switch so the surface stays at a consistent temperature just like fans so condensation would be no different. As long as the surface temperature stays at or above ambient you won't get condensation.

The bottom line is many high powered systems already exist which don't use fans so it can be done and it can still be done better. I'm not sure why you all feel the need to debate that, if you like fans go nuts but I'd prefer a system without fans. It's a simple personal preference I guess, and I'm entitled to it.
