Boxed Processor Specifications
10.3.1 Boxed Processor Cooling Requirements
As previously stated the boxed processor will have three thermal solutions available.
Each configuration will require unique design considerations. Meeting the processor’s
temperature specifications is also the function of the thermal design of the entire
system, and ultimately the responsibility of the system integrator. The processor
temperature specifications are found in Section 5, “Thermal Management
Specifications" of this document.
10.3.1.1 STS100C(Passive / Active Combination Heat Sink Solution)
The active configuration of the combination solution is designed to help pedestal
chassis users to meet the thermal processor requirements without the use of processor
chassis ducting. However, it is strongly recommended to implement some form of air
duct to meet memory cooling and processor T
LA
temperature requirements. Use of the
active configuration in a 2U rackmount chassis is not recommended.
In the passive configuration it is assumed that a chassis duct will be implemented.
For a list processor and thermal solution boundary conditions, such as Psi
ca
, T
LA
,
airflow, flow impedance, etc, see Table 10-4. It is recommended that the ambient air
temperature outside of the chassis be kept at or below 35
°C. Meeting the processor’s
temperature specification is the responsibility of the system integrator.
This thermal solution is for use with processor SKUs no higher than 95W (8 and 10
Core) or 80W (4 and 6 core).
10.3.1.2 STS100A (Active Heat Sink Solution) (Pedestal only)
The active configuration of the combination solution is designed to help pedestal
chassis users to meet the thermal processor requirements without the use of processor
chassis ducting. It is strongly recommended to implement some form of air duct to
meet memory cooling and processor T
LA
temperature requirements. Use of the active
configuration in a 2U rackmount chassis is not recommended.
