Positive or negative air pressure?

Who_me_33 · Post by **Who_me_33** » Fri Oct 15, 2004 3:31 pm

The subject sums up the question. is it best to have positive or negative air pressure inside your case. So do i want more intake fans or more exhaust fans. And would the preformance of an aero7+ improve if i rotated the fan, so the intake is fasing an exhaust fan, change the exhaust fan so that it is an intake fan, and duct air to the aero7 (the aero 7 should arrive in the next couple of days).
Thanks in advance
Nick

Ditto. And you could try turning the HS fan around... but normaly it works best the way it comes... just run it normal and monitor temps.. then reverse it and monitor temps and that should show you whats what.

this has been bugging me, why do you need a fan on the front in a system that only has intake air holes at the front?

after all the fan in the back will suck the same amount of air into the case as out.

if you have a fan in the back only, it will cause a stain on it unless you have one in the front pulling air in for it.
