This section describes the cooling requirements of the fan heatsink solution used by the 

boxed processor.

The boxed processor may be directly cooled with a fan heatsink. However, meeting the 

processor's temperature specification is also a function of the thermal design of the 

entire system, and ultimately the responsibility of the system integrator. The processor 

temperature specification is provided in 

. The boxed processor fan heatsink is 

able to keep the processor temperature within the specifications (see 

) in 

chassis that provide good thermal management. For the 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. 

 illustrate an acceptable 

airspace clearance for the fan heatsink. The air temperature entering the fan should be 

kept below 38 ºC. Again, meeting the processor's temperature specification is the 

responsibility of the system integrator.
