Less than 800sf, that is like 20X40, or do you mean 80sf. you need at least passive intake down low, then if you put your bigger fan on the light ducted out of the room you should be able to get it down. What is the ambient temp outside the room?
McDanger Reviewed by McDanger on . Heat-What I am doing wrong? Well I started to get heat problems with temps around 90 so I decided to add a 500 cfm exhaust fan at the top of my room to take out the heat. The problem is that it only made the temps go down like 2 degrees. Is this because I have no intake air or is my fan not big enough? My room is less than 800 sq ft. I have a 1000w light with a 180 cfm exhasut fan connected to it and the duct is very hot so I know its working. Instead of hooking up the new 500 cfm fan at the top of my room should I switch Rating: 5
