[. . . ] Airflow of the fan heatsink is into the center and out of the sides of the fan heatsink. Airspace is required around the fan to ensure that the airflow through the fan heatsink is not blocked. Blocking the airflow to the fan heatsink reduces the cooling efficiency and decreases fan life. Figure 8-7 and Figure 8-8 illustrate an acceptable airspace clearance for the fan heatsink. [. . . ]
