temp 12 g nano

[i2go]

I have a 12g nano cube, softie tank, no fish. I have stock lighting 11v, 24watt. Two fns cooling them, and i have my heater set to 76F. My thermometer says my water is 85F, any suggestions how to cool it down? or wats going on? I have a regular computer fan, but i dont know how to turn that into a working fan w/o the comp.

is the heater stuck "on"? check that. Also, open the lid...that will help a little probably, but if not, try putting just a small 4 inch fan from walmart over the open part...see if that helps. It lowered my 55 5 degrees, so it'd proly be good on a 12 also

I dropped my temps to a stable <80F with just a 80mm fan installed onto the feeder lid. I used a dremel to make a blowhole and tapped into the stock wiring for the existing fan. I finished it up with a fan filter which gave it the "OE Look".
