Abstract: The Intel® Core™ Duo processor is the first mobile processor that uses Chip Multi-Processing (CMP) on-die technology to maximize performance and minimize power consumption.
The Intel Xeon Processor uses the Thermal Monitor feature to protect the processor during times where the silicon would otherwise operate above specification. (The term Boxed Intel® Xeon® Processors refers to processors packaged for use by system integrators.)Thermal management in boxed Intel Xeon Processor-based systems can affect both the performance and noise level of the system. Integrators who follow the recommendations presented can provide their customers with more reliable systems and will see fewer customers returning with thermal management issues. This document assumes a general knowledge of and experience with system operation, integration, and thermal management. Can you give me some thermal management basics?Systems using Intel® Xeon® Processors require thermal management. The processor wind tunnel (PWT) is only intended for use with general purpose server (2U and above) Intel Xeon processor, not the Intel Xeon Processor MP or the Intel Xeon Processor for 1U Rack Mount Servers.
This processor fan operates at a constant speed. Information on the Thermal Monitor feature can be found in the Intel Xeon Processor Datasheet.Additionally, the boxed Intel Xeon Processor heat sink uses an active duct solution called the Processor Wind Tunnel (PWT), which includes a high quality fan. It is critical that systems be designed to maintain low enough internal ambient temperatures to prevent the Intel Xeon Processor from entering a Thermal Monitor active state. While the Thermal Monitor feature is active, the system's performance may drop below its normal peak performance level. The feature is intended to provide protection for unusual circumstances like higher than normal ambient air temperatures or failure of a system thermal management component (such as a system fan).
The ultimate goal of thermal management is to keep the processor at or below its maximum operating temperature.Proper thermal management is achieved when heat is transferred from the processor to the system air, which is then vented out of the system. What is proper thermal management?Proper thermal management depends on two major elements: a heat sink properly mounted to the processor, and effective airflow through the system chassis. System integrators using the boxed Intel Xeon Processor should become familiar with this document. This document details specific thermal requirements of the boxed Intel Xeon Processor. When building quality systems using the boxed Intel Xeon Processor, it is imperative to carefully consider the thermal management of the system and verify the system design with thermal testing. Meeting the processor's temperature specification is ultimately the responsibility of the system integrator.
Intel Thermal Manager Install The Heat
This air stream transfers heat from the heat sink to the air inside the system. Be sure to follow the installation procedures documented in the boxed processor manual and the integration overview.The fan on the Processor Wind Tunnel is a high-quality ball bearing fan that provides a good local air stream. Thermal interface material (applied during system integration) provides effective heat transfer from the processor to the fan heatsink.Critical: Using the boxed processor without properly applying the included thermal interface material will void the boxed processor warranty and may cause damage to the processor. Thermal management operations How do I install the heat sink? You must securely attach the heat sink (included with the boxed Intel Xeon Processor) to the processor. It is the responsibility of the system integrator to ensure adequate system airflow.
How do I manage system airflow?The following are factors which determine system airflow: Without a steady stream of air through the system, the fan heat sink will re-circulate warm air, and therefore may not cool the processor adequately. Sufficient system airflow is also needed in order to exhaust the air.
Cosmetic vents are designed to look as if they allow air flow but little or no air flow actually exists. Chassis vents must be functional and not excessive in quantity: Integrators should be careful not to select chassis that contain cosmetic vents only. However, some chassis designed exclusively for Server AT form factor motherboards may yield efficient cooling.The following is a list of guidelines to be used when integrating a system: Due to cooling and voltage considerations, Intel recommends the use of ATX form factor motherboards and chassis for the boxed Intel Xeon Processor.Server AT form factor motherboards are not recommended because such designs are not standardized for effective thermal management. Proper attention to airflow when selecting subassemblies and building systems is important for good thermal management and reliable system operation.Integrators use two basic motherboard-chassis-power supply form factors for servers and workstations: ATX variations and the older Server AT form factor.
The best locations for air intakes allow air to enter the chassis and directly flow over the processor. Vents must be properly located: Systems must have properly located intake and exhaust vents. Otherwise, the I/O opening may provide for excessive venting. In ATX chassis, I/O shields must be present. In this case, very little air flows over the processor and other components.
A system fan is typically used with passive heat sinks. System Fan - Should It Be Used? Some chassis may contain a system fan (in addition to the power supply fan) to facilitate airflow. Wire finger guards for the power supply fan offer much less airflow resistance than openings stamped into the sheet metal casing of the power supply unit. Choose a power supply unit with large vents. Power Supply Venting: A lot of air flows through the power supply unit, which can be a significant restriction if not well vented. For some chassis where the processor is running too warm, changing to a power supply with a stronger fan can greatly improve airflow.
Improper positioning of the exhaust fan, adapter cards, cables, or chassis brackets and subassemblies blocking the airflow within the system, can create such areas. Protect Against Hot Spots: A system may have a strong airflow, but still contain hot spots. Hot spots are areas within the chassis that are significantly warmer than the rest of the chassis air. For example, a system fan in an ATX system should act as an exhaust fan, pulling air from within the system out through the rear or front chassis vents. System Fan Airflow Direction: When using a system fan, ensure that it draws air in the same direction as the overall system airflow. Thermal testing both with a system fan and without the fan will reveal which configuration is best for a specific chassis.
Thermal testing can determine if a specific chassis-power supply-motherboard configuration provides adequate airflow for boxed Intel Xeon Processors. Thermal testing is highly recommended when choosing a new supplier for motherboards or chassis, or when starting to use new products.
