| If more air enters
the case through the intake fans than leave at the
exhaust fans the surplus air will leave through any
other gap in the case, preventing dust from
entering. Exhaust fans will also work easier because
of positive back pressure. This equates to positive
pressure. If on the other hand your exhaust fans
push air out faster than your intake fans can
supply, air will enter through every other opening
in the case like optical drive bays, USB and other
ports. Exhaust fans will also have to work harder to
expel hot air because of negative back pressure.
This is referred to as negative pressure.

| Positive pressure
inside your case will help keep it clean and
therefore cooler, as more air will theoretically
enter the case than leave it. In the real world this
is more difficult to achieve because of computer
cases not being airtight. The more air you put into
the case the faster it will run out the other side
(through exhaust fans and case openings combined).
In a positive pressure setup the incoming air can be
filtered by fitting DEMCiflex Air Filter.
