10 Thermal/Mechanical Design Guide
1.1.3 Document Scope
This design guide supports the following processors:
• Pentium 4 processors 570/571, 560/561, 550/551, 540/541, 530/531, and 520/521 in the 775-
land LGA package
• Pentium 4 processor 670/672, 660/662, 650, 640, and 630 in the 775-land LGA package
• Pentium 4 processor Extreme Edition in the 775-land LGA package
In this document, when a reference is made to “the processor” and/or “the Pentium 4 processor in
the 775–Land LGA package”, it is intended that this includes all the processors supported by this
document. If needed for clarity, the specific processor will be listed.
In this document, when a reference is made to “the datasheet”, the reader should refer to either the

Chapter
2 discusses package thermal mechanical requirements to design a thermal solution for the
Pentium 4 processor in the 775–land LGA package in the context of personal computer
applications. Chapter
3 discusses the thermal solution considerations and metrology
recommendations to validate a processor thermal solution. Chapter
4 addresses the benefits of the
processor’s integrated thermal management logic for thermal design.
Chapter
5 provides information on the common Intel reference thermal solution for the Pentium 4
processor in the 775–land LGA package discussed in this document. Chapter
6 discusses the
implementation of acoustic fan speed control.
