Thanks man! The panels stay quite cool driven up to about 80% on the dial. At max it does produce out heat. But not to the point of where i cant hold my hand on it. I use the fans for both lights. No drill holes in the panel. But i should put the rubber stoppers on the bottom of the fans to elevate em to help draw the air better. I just have it where the 43cfm fan pulls the hot air from the panel. As i adjust the dial on the driver the fans adjust with the light. So at max power the fans rpms are greater than when say the dials at half. If that makes any sense. Lol im stoned tryna type.
