Boxed Processor Specifications
around the heatsink. It is assumed that a 40°C T
LA
 is met. This requires a superior 
chassis design to limit the T
RISE
 at or below 5°C with an external ambient temperature 
of 35°C. These specifications apply to both copper and aluminum heatsink solutions. 
Following these guidelines allows the designer to meet Quad-Core Intel® Xeon® 
Processor 5400 Series Thermal Profile and conform to the thermal requirements of the 
processor.
8.3.2.2
1U Passive/3U+ Active Combination Heat Sink Solution (Pedestal 
Active)
The active configuration of the combination solution is designed to help pedestal 
chassis users to meet the thermal processor requirements without the use of chassis 
ducting. It may be still be necessary to implement some form of chassis air guide or air 
duct to meet the T
LA
 temperature of 40
°
C depending on the pedestal chassis layout. 
Also, while the active thermal solution design will mechanically fit into a 2U volumetric, 
it may not provide adequate airflow. This is due to the requirement of additional space 
at the top of the thermal solution to allow sufficient airflow into the heat sink fan. Use 
of the active configuration in a 2U rackmount chassis is not recommended.
It is recommended that the ambient air temperature outside of the chassis be kept at 
or below 35°C. The air passing directly over the processor thermal solution should not 
be preheated by other system components. Meeting the processor’s temperature 
specification is the responsibility of the system integrator.
8.3.2.3
2U Passive Heat Sink Solution (2U+ Rack or Pedestal)
In the 2U+ passive configuration, it is assumed that a chassis duct will be implemented 
to provide a minimum airflow of 27 cfm at 0.182 in. H
2
O (45.9 m
3
/hr at 45.3 Pa) of 
flow impedance. The duct should be carefully designed to minimize the airflow bypass 
around the heatsink. These specifications apply to both copper and aluminum heatsink 
solutions. The T
LA
 temperature of 40
°
C should be met. This may require the use of 
superior design techniques to keep T
RISE
 at or below 5°C based on an ambient external 
temperature of 35°C.

Boxed Processor Contents
A direct chassis attach method must be used to avoid problems related to shock and 
vibration. The board must not bend beyond specification in order to avoid damage. The 
boxed processor contains the components necessary to solve both issues. The boxed 
processor will include the following items:
• Quad-Core Intel® Xeon® Processor 5400 Series 
• Unattached heat sink solution
• Four screws, four springs, and four heat sink standoffs (all captive to the heat sink)
• Foam air bypass pad and skirt (included with 1U passive/3U+ active solution)
• Thermal interface material (pre-applied on heat sink)
• Installation and warranty manual
• Intel  Inside  Logo
Other items listed in 
 that are required to complete this solution will be 
shipped with either the chassis or boards. They are as follows:
• CEK Spring (supplied by baseboard vendors)
• Chassis standoffs (supplied by chassis vendors)
