Boxed Processor Specifications
7.3
Thermal Specifications
This section describes the cooling requirements of the fan heatsink solution utilized 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
found in Chapter 5 of this document. The boxed processor fan heatsink is able to keep the
processor temperature within the specifications (see Table 5-1) 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. Figure 7-7 and Figure 7-8 illustrate an acceptable
airspace clearance for the fan heatsink. The air temperature entering the fan should be kept below
39 C. A Thermally Advantaged Chassis with an Air Guide 1.1 is recommended to meet the 39 C
requirement. Again, meeting the processor's temperature specification is the responsibility of the
system integrator.
Note:
The processor fan is the primary source of airflow for cooling the VCC voltage regulator. Dedicated
voltage regulator cooling components may be necessary if the selected fan is not capable of
keeping regulator components below maximum rated temperatures.
