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 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. 

 and 

 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.
