This section describes the cooling requirements of the thermal module assembly 

solution used by the boxed processor.

The boxed processor may be directly cooled with a TMA. 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 

case temperature specification is in 

. The boxed processor TMA is able to 

keep the processor temperature within the specifications in 

 for chassis that 

provide good thermal management. For the boxed processor TMA to operate properly, 

it is critical that the airflow provided to the TMA is unimpeded. Airflow of the TMA is into 

the duct and out of the rear of the duct in a linear flow. Blocking the airflow to the TMA 

inlet reduces the cooling efficiency and decreases fan life. Filters will reduce or impede 

airflow which will result in a reduced performance of the TMA. The air temperature 

entering the fan should be kept below 35.5°C. Again, meeting the processor's 

temperature specification is the responsibility of the system integrator.
