If needed for clarity, the specific processor will be listed. In this document, when a reference is made to "the reference design" it is intended that this includes all ATX reference designs (RCFH-4, RCBFH-3, and D60188-001) supported by this document. If needed for clarity, the specific reference design will be listed. In this document, when a reference is made to "the datasheet", the reader should refer to the Intel® Core™2 Extreme Quad-Core Processor QX6000 Sequence and Intel® Core™2 Quad Processor Q6000 Sequence Datasheet and the Intel® Core™2 Extreme Processor QX9000 Series and Intel® Core™2 Quad Processor Q9000, Q9000S, Q8000, and Q8000S Series Datasheet as appropriate. In this document, for the Intel® Core™2 Quad processor Q9000S and Q8000S series at 65 W thermal solution, refer to the Intel® Core™2 Duo Processor E8000 and E7000 Series and Intel® Pentium® Dual-Core Processor E5000 Series Thermal and Mechanical Design Guide (TMDG), as appropriate. Chapter 2 of this document discusses package thermal mechanical requirements to design a thermal solution for the processor 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 Intel reference thermal solution for the processor. Chapter 6 discusses the implementation of acoustic fan speed control. 12 Thermal and Mechanical Design Guidelines
