I am using a 9.3 cfm blower with a mypin TA7 controller. The fan is mounted to a cat bowl that I found at Walmart. All of that works great. I guess my problem is with the one vent completely open because of the fan, it is allowing too much air to flow without the fan even being energized. I need to install a check valve of sorts on the fan to prevent any free airflow, and maybe put a gasket on the door. I guess I had some unrealistic expectation that I would be able to just hook it up and forget about it and it would keep it within a reasonable range. It may actually work better on my Mini WSM as it has a much tighter seal.
