Yeah, I have ventilation which is turning the air over in the cabinet several times per minutes. And I really need to add more ventilation to get the temperature down a little. Ultimately, that's the problem though. With that much air circulating through, the cabinet is never going to be that much more humid than the room it's in. At this very moment the cabinet is 86 degrees, 20% RH. The room is 70 degrees, 26% RH.
