I was thinking about moving it (the Hydra) to the middle. I think the issue might be the drawers in the middle that are blocking alot of air flow. I haven't heard of anyone who has the same unit having these issues though.
I like the idea of running the tubing and "venting" every so often, but don't think it'll work due to the shelving/drawers. I'll check the clearances tonight.
Thanks for the input!!
