The upper air is pushed into the case with three 80mm intake
fans. It could also use 2 120mm fans, if I ever find two that is more
silent then three 80mm fans. The airflow goes from the fans, pushed
onto the motherboard components, cpu and cards and the hottest air at
the ceiling is pushed out through a noise lock. <br clear=left><img src=../pics/empty_flow.jpeg width=897 height=1040><br>
