ATX Thermal/Mechanical Design Information 6 ATX Thermal/Mechanical Design Information 6.1 ATX Reference Design Requirements This chapter will document the requirements for an active air-cooled design, with a fan installed at the top of the heatsink. The thermal technology required for the processor. The processors of Intel® Core™2 Duo processor with 4 MB cache at Tc-max of 60.1 °C, Intel® Core™2 Duo processor with 2 MB cache at Tc-max of 61.4 °C and Intel® Pentium® Dual Core processor E2000 series at Tc-max of 61.4 °C require a thermal solution equivalent to the D60188-001 reference design, see Figure 6-1 for an exploded view of this reference design. Note: The part number D60188-001 provided in this document is for reference only. The revision number -001 may be subject to change without notice. The D60188-001 reference design takes advantage of an acoustic improvement to reduce the fan speed to show the acoustic advantage (its acoustic results show in the Table 6-3). The D60188-001 reference design takes advantage of the cost saving for the light fan/heatsink mass (450g) and the new TIM material (Dow Corning TC-1996 grease). A bottom view of the copper core applied by this grease is provided Figure 6-3. Thermal and Mechanical Design Guidelines 55
