Re: Fan direction on TEK485
One reason for positive pressure cooling is that it reduces dust. Air is draw in through the filter which removes the dust (one hopes) and blows it through out the chassis.toggle quoted messageShow quoted text
However, positive pressure works when the chassis is designed for it, otherwise cooling may be better with a fan blowing out to exhaust warm air. Positive pressure design is not trivial; you want the greatest cooling where the greatest amount of heat is produced but don't want that air heating up the rest of the chassis. The chassis must be sealed well enough to control the air flow. Sometimes the blower must be some distance away from the hot spots.
