Surely we are very curious "Tiny Cooling Fan" need to look at the distribution of heat within the chassis fan airflow through the chassis is generally installed in front of the chassis, the cold air blowing over the front suction board, and finally discharged from the power supply fan, convection. Best to consider the direction of the air flow problem, the best solution is to install a before and after "Tiny Cooling Fan", diagonal direction distribution, then the entire chassis cooling effect is very good. Front chassis fan blowing on the inside, the outside rear fan blow. Convection CPU, other chip time cards, hard drives, optical drives, North bridge, South bridge and boards on the air in the heating enclosure, if those warm air to escape outside the box, "Tiny Cooling Fan" will seriously affect the components heat, affect the life of the computer.
