What's up guys, anyone with a biocube and a lid knows reefing can make temps go way up, to help with this I installed a fan to my hinge on my lid. I used a wire holder and glued it to the lid so the lid functions without the wire falling into the water. The fan has its own controller and has good RPM, it's hooked up to an inkbird cooling/heating controller. Simple cooling solution that cost me little and still has decent water retention.
I used a 75mm drill bit off Amazon for fan hole, 80mm fan with controller off Amazon, inkbird controller off Amazon.
