ATX Thermal/Mechanical Design Information 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 TA assumption of 40 °C for the Intel reference thermal solution at the processor fan heatsink inlet discussed Section 2.4.1. Table 6-1. E18764-001 Reference Heatsink Performance Processor Target Thermal Performance, Ψca (Mean + 3σ) Assum TAption Notes 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 / Intel® Celeron® processor E3000 series 0.50 °C/W 0.52 °C/W 40 °C 40 °C 1, 2 1, 2 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.
