| The
power supply fan exhausts the hot air created
by the CPU and other components within the
case.
The power
supply is located at the top rear of the case,
due to the fact that hot air rises.
With only
the power supply fan, pulling air out of the
case this causes a small negative air
pressure.
With the
hotter air being exhausted at the top of the
case, this is replaced with other air rising.
Hence there is airflow. |
