Vortex Sound Research

Hi there,

I'm using a Trogotronic 168 case. After a few hours of use, I felt the underside of the case and, even through that thick case, it felt pretty warm from the bricks inside. I'm wondering if there's anything to fear from the heat being (somewhat) close to the modules. It is a deep case, there is a slight space between the case and the table, and there is also a centimeter and a half on either side of the rails, all of which affords some ventilation, I suppose. Is there any cause for concern here or is this par for the course? Are the modules fine with some heat behind them?

Thanks.
