Fans - How to use them

[Memnoch]

Hi all. i've been reading about using fans to cool down a tank. But couldnt find any references to how they are used? Do u blow on the water surface? or blow on the lighting setup?

Sorry if this sounds stupid...

:P

usually one will tilt the fans at an angle blowing the water surface, this way water be evaporate, thus heat are loss.
depends on the temperature you trying to reach, blowing on the water surface are better to bring the temperature cooler(had mine hover average 26c). else blowing at light sets, probably be able to hover at 27-28c depends on the atmosphere temperature.

if you're looking for fan, try to get one from Profantec or else get one from Tornado if budget not that tight. (Heard alot of good reviews on the Tornado). Personally i'm using Profantec, very happy with it, not too noisy
