1.0 Introduction

As the complexity of computer systems increases, so do the power dissipation

requirements. Care must be taken to ensure that the additional power is properly

dissipated. Typical methods to improve heat dissipation include selective use of

ducting, and/or passive heatsinks.

The goals of this document are to:

• Outline the thermal and mechanical operating limits and specifications for the

Intel®5100 Memory Controller Hub Chipset (Intel®5100 MCH Chipset)

• Describe reference thermal solutions that meet the specification of the Intel®5100

MCH Chipset

Properly designed thermal solutions provide adequate cooling to maintain the Intel®

5100 MCH Chipset die temperatures at or below thermal specifications. This is

accomplished by providing a low local-ambient temperature, ensuring adequate local

airflow, and minimizing the die to local-ambient thermal resistance. By maintaining the

Intel®5100 MCH Chipset die temperature at or below the specified limits, a system

designer can ensure the proper functionality, performance, and reliability of the

chipset. Operation outside the functional limits can degrade system performance and

may cause permanent changes in the operating characteristics of the component.

The simplest and most cost effective method to improve the inherent system cooling

characteristics is through careful chassis design and placement of fans, vents, and

ducts. When additional cooling is required, component thermal solutions may be

implemented in conjunction with system thermal solutions. The size of the fan or

heatsink can be varied to balance size and space constraints with acoustic noise.

This document addresses thermal design and specifications for the Intel®5100 MCH

Chipset components only. For thermal design information on other chipset components,

refer to the respective component datasheet. For the ICH9R, refer to the Intel®I/O

Controller Hub 9 (ICH9) Family Thermal and Mechanical Design Guidelines.

Note: Unless otherwise specified, the term “MCH” refers to the Intel®5100 MCH Chipset.

1.1 Design Flow

To develop a reliable, cost-effective thermal solution, several tools have been provided

to the system designer. Figure 1 illustrates the design process implicit to this document

and the tools appropriate for each step.

Term Definition

FC-BGA

Flip Chip Ball Grid Array. A package type defined by a plastic substrate where

a die is mounted using an underfill C4 (Controlled Collapse Chip Connection)

attach style. The primary electrical interface is an array of solder balls

attached to the substrate opposite the die.

Note: The device arrives at the customer with solder balls attached.

BLT Bond line thickness. Final settled thickness of the thermal interface material

after installation of heatsink.

ICH9 I/O Controller Hub 9

IHS Integrated Heat Spreader

MCH Memory controller hub. The chipset component that contains the processor

interface, the memory interface, the PCI Express* interface and the ESI

interface.

Tcase_max Maximum allowed component temperature. This temperature is measured at

the geometric center of the top of the package IHS.

Tcase_min Minimum allowed component temperature. This temperature is measured at

the geometric center of the top of the package IHS.

TDP Thermal design power. Thermal solutions should be designed to dissipate

this target power level. TDP is not the maximum power that the chipset can

dissipate.

TIM Thermal Interface Material

ΨCA Case-to-ambient thermal characterization parameter. A measure of the

thermal solution thermal performance including TIM using the thermal

design power. Defined as (TCASE - TLA) / TDP

ΨCS Case-to-sink thermal characterization parameter. A measure of the TIM

thermal performance using the thermal design power. Defined as (TCASE -

TLA) / TDP

ΨSA Sink-to-ambient thermal characterization parameter. A measure of heatsink

thermal performance using the thermal design power. Defined as (TCASE -

TLA) / TDP
