Introduction
Intel boxed processors are intended for system integrators who build systems from 
components available through distribution channels. The Dual-Core Intel
®
 Xeon
®
 
Processor 5000 series will be offered as an Intel boxed processor.
Intel will offer the Dual-Core Intel Xeon Processor 5000 series boxed processor with 
two heat sink configurations available for each processor frequency: 1U passive/2U 
active combination solution and a 2U passive only solution. The 1U passive/2U active 
combination solution is based on a 1U passive heat sink with a removable fan that will 
be pre-attached at shipping. This heat sink solution is intended to be used as either a 
1U passive heat sink or a 2U+ active heat sink. Although the active combination 
solution with removable fan mechanically fits into a 2U keepout, additional design 
considerations may need to be addressed to provide sufficient airflow to the fan inlet.
The 1U passive/2U active combination solution in the active fan configuration is 
primarily designed to be used in a pedestal chassis where sufficient air inlet space is 
present and strong side directional airflow is not an issue. The 1U passive/active 
combination solution with the fan removed and the 2U passive thermal solution require 
the use of chassis ducting and are targeted for use in rack mount servers. The 
retention solution used for these products is called the Common Enabling Kit, or CEK. 
The CEK base is compatible with both thermal solutions and uses the same hole 
locations as the Intel® Xeon® processor with 800 MHz FSB.
The 1U passive/active combination solution will utilize a removable fan with a 4-pin 
pulse width modulated (PWM) T-diode control. Use of a 4-pin PWM T-diode controlled 
active thermal solution helps customers meet acoustic targets in pedestal platforms 
through the motherboards’s ability to directly control the RPM of the processor heat 
sink fan. Please se
