One of our major concerns when considering the vertical docking station was how the MacBook's ability to vent heat would be affected when running closed while standing on its end. Turns out there's no adverse effects on performance. In fact, we noticed a drop in enclosure temps versus running the computer open on a desk, but nothing ground breaking. The temp drop is probably just due to the fact that more of the case is exposed to the air when it is sitting upright, allowing the metal body to shed more heat. We've run a bunch of extended CPU load tests, in a variety of temperature conditions. The upper end was an 45 minute test in a room brought to 90 degrees. CPU temps spiked in both the normal and docked tests, but once the fan wound up to full blast the temps quickly stabilized and remained the same in both tests. I couldn't be happier, as Hannibal from the A-Team said, "I love it when a plan comes together..."
