I'm thinking about cutting a hole above the doors at kitchen and going upstairs for floor diffuser or floor register, as a vent. To let heat that's trapped above door pass through. I have a couple of 120mm 12V fans and wondering about placing them in behind vents. Looking for power source now. Anyone want to pick this apart? Ideas, and suggestions? Thanks. Other than the fact, that the flapping house might fall, if I cut a load bearing member.
