I'm thinking of adding a computer fan to my tank lid...but I don't want it to cause more evaporation in the water so that I have to do more top-offs.
Basically, if I take the lid off my tank then my tank temp. goes down about 0.5°C (when the lights are on). So I'd like to keep the lid on but blow all the hot air out...
There's a hole I've made in the right of the lid (where all the filter pipes fit through etc.) so do you think I could mount the fan at the left of the lid and have it blowing the air across to the right? This shouldn't cause any extra evaporation should it? And do you think it'd be efficient in cooling my lid down?
Are computer fans very quiet? Or even silent?
And, would it be possible to put a thermostat onto it with little effort (and make the fan and thermostat suitable to be in an aquarium lid, ie. encase them or whatever) so that the fan turns on or off with the heat??
