I will make a How-to video for all the steps and equipment involved. Briefly, I used 2 L-brackets (6" inch) and 3x 4" inch 12V 0.3A fans in a parallel configuration with a 12V 2A barrel plug charger. For support, I used 4x 2" inch flat tip nut screws.An excellent example of DIY.
As I also live in a hot climate I know a little of what it’s like?
Be aware the water level will drop faster with the fans. No problem if you are at home to top it up.
Consider a timer to stop the noise at night.
Well done. Thanks for sharing raptor22
