Thermal Specifications
This section describes the cooling requirements of the fan heatsink solution used by the boxed
processor.
7.3.1
Boxed Processor Cooling Requirements
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
presented in Chapter 5. The boxed processor fan heatsink is able to keep the processor temperature
within the specifications (see Table 26) in chassis that provide good thermal management. For the
