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.
