So, I have built one of these before, just a simple build with the controller and outlet. However, I want to try one with a fan. I have two questions:
1. What is a good 120v AC computer case fan to use? I'd like a larger one (120mm) to keep noise down
2. Is there any advantage to having the fan run constantly to keep air circulating instead of just having it run when the heat/cool circuits are activated? I was thinking about wiring the fan in with a rheostat and just keeping it at a set RPM 24/7.
I tried doing a search but the results were a bit overwhelming.
