Tony Montana Posted March 8, 2014 Share Posted March 8, 2014 Opening the vents is fine mate, you don't have to have an intake fan 1 Link to comment Share on other sites More sharing options...
Guest Cool Bananas Posted March 9, 2014 Share Posted March 9, 2014 No, passive intake will be fine with that kinda setup. Just make sure no light is getting in during your dark period. Link to comment Share on other sites More sharing options...
