I am going to to mod a computer fan that i am going to buy to plug into the wall socket, to make sure the fan doesn't burn out i am going to take a 12 v dc adapter and strip the ends of the wires off it and connect those wires to the fans wires and then solder them together and wrap it in electrical tape to put on top of my terrarium to improve the ventilation for my exo terra fogger so the fog doesn't just sit on the bottom of the tank.. let me know what you think
