I'm currently experimenting with some small ducts. (to read about it, click here)
Anyway, I was wondering about the best fan location in a duct. Is it easier for a fan to push air through a duct or pull air through a duct? Ideally, for a long duct, you would probably want fans on each end and fans along the length of the duct pulling and pushing air. But, what about a short duct where you are limited to one fan? Would it matter if the duct is for exhaust or intake? For example, if you had a duct located near the heatsink to remove the hot air, should the fan be located on the inside of the duct to push air out? Or should the fan be located on the outside near the case to pull the air through the duct? Or, for a third option, would it be better to have the fan in the center of the duct? Maybe it all depends on the environment, type of duct, etc.
Has anyone ever done tests on this type of stuff? Any HVAC experts know the answers?
