This section describes the cooling requirements of the fan heatsink solution utilized 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 is 
ultimately the responsibility of the system integrator. The processor temperature specification is 

found 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 be unimpeded. Airflow 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 40 °C. Again, meeting the processor's 
temperature specification is the responsibility of the system integrator.
