Boxed Processor Specifications
boxed processor fan heatsink to operate properly, it is critical that the airflow provided to the fan
heatsink is unimpeded. 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 20
The air temperature entering the fan is required to be at or below 38 °C. Again, meeting the
processor's temperature specification is the responsibility of the system integrator.
