6.2.1

Heatsink Performance

Table 6-1 provides the D60188-001 heatsink performance for the processors of Intel
™
Core 2 Duo processor with 4 MB cache at Tc-max of 60.1 °C, Intel
processor with 2 MB cache at Tc-max of 61.4 °C, and Intel
processor E2000 series at Tc-max of 61.4 °C. Table 6-2 provides the E18764-001
heatsink performance for the processors of Intel
2 MB cache at Tc-max of 72.0 °C and Intel
Tc-max of 73.3 °C, Intel
73.3 °C, and Intel
The results are based on the test procedure described in Section 6.2.4.
The tables also include a T
solution at the processor fan heatsink inlet discussed Section 2.4.1.
