6.2 Validation Results for Reference Design
6.2.1 Heatsink Performance
Table 6–1 provides the E18764-001 heatsink performance for the processors of Intel
Core™2 Duo processor E8000 series with 6 MB cache, Intel Core™2 Duo processor
E7000 series with 3 MB cache, Intel Pentium dual-core processor E6000, E5000 series
with 2 MB cache, and Intel
®
Celeron
®
processor E3000 series with 1 MB cache. The
results are based on the test procedure described in Section 6.2.4.
The tables also include a T
A
assumption of 40 °C for the Intel reference thermal
solution at the processor fan heatsink inlet discussed Section 2.4.1.

NOTES:
1. Performance targets (Ψ ca) as measured with a live processor at TDP.
2. The difference in Ψ ca between the Intel Core™2 Duo processor E8000 series with
6 MB cache and Intel Core™2 Duo processor E7000 series with 3 MB cache, Intel
Pentium dual-core processor E6000, E5000 series with 2 MB cache, and Intel
®
Celeron
®
processor E3000 series with 1 MB cache is due to a slight difference in the die size.
