I set this 29 up yesterday and was very surprised by the noise from the cooling fan from the light. The fan doesn’t make a sound like it’s broken, like a rattle. It just sounds like a fan moving a lot of air. Much louder that a computer fan, kind of like my wife just started vacuuming in the other room. If this is how it’s supposed to be I can’t imagine ever using that light. Could someone with one of these tanks tell me if this is how they are or if mine is a little messed up? Thanks..
