DaveSamsell Posted August 28, 2020 Share Posted August 28, 2020 One of my aquariums has been running a bit hot in temperature and wanted to try an experiment anyway. Was curious how much the temperature would actually drop, by using a low voltage fan. Salvaged a computer power supply fan and wired it up for portable (12 volt battery) or fixed (wall transformer) operation. Will use removable Velcro to adhere the fan to the tank's top rim. Now, to try it out and see how well it performs. 12 volt / 300mA box fan with installed alligator leads In-line safety fuse installed 2 Link to comment Share on other sites More sharing options...
pedrofisk Posted August 28, 2020 Share Posted August 28, 2020 I'll be interested to see how it goes. Keep an eye on evaporation. 1 Link to comment Share on other sites More sharing options...

Keep an eye on evaporation. @pedrofisk, The aquarium chiller worked well on a 10 gallon tank, rather quickly. It dropped the tank temperature 9 degrees Far. in several hours. I would imagine results would be variable, dependent on the angle of air flow, etc. Evaporation was mild to moderate and the humidity did rise about 6 percent in the 'average sized room', where the tank is located. 1 1 Link to comment Share on other sites More sharing options...
TheDukeAnumber1 Posted August 29, 2020 Share Posted August 29, 2020 Ty for sharing, I would love to see a test done using a peltier and a fan that goes against the glass. Much more to do but IMO it would be pretty cool and remove the evaporation issues. Link to comment Share on other sites More sharing options...
