A properly cooled system can help the processor run more reliably and minimize acoustic noise levels generated from running the cooling fan at higher speeds.
Intel's thermal specifications recommend the use of a Thermally Advantaged Chassis (TAC) version 1.1 for Intel® Core™2 Quad processor, Intel® Core™2 Duo processor, the Intel® Pentium® D processor, and the Intel® Pentium® 4 processor-based systems. Intel also recommends the use of a Thermally Advantaged Chassis (TAC) version 1.0 for Celeron® D processor-based systems.
To meet the thermal specification requirements of the Intel Pentium D processor, use a chassis that can help maintain an internal ambient temperature below 39°C. Intel also recommends that you use a chassis that can help maintain an internal ambient temperature below 40°C when using the Intel Core2 Quad processor, the Intel Core2 Duo processor, the Intel Pentium 4 processor and the Intel Celeron D processor based on 65nm or 90nm process technology.
This chassis list is being provided to Intel resellers to aid in the system integration process. Intel has determined these chassis meet the MINIMUM thermal, mechanical fit and functional compatibility to support the processors listed here. However, power supplies have not been validated to meet the electrical requirement of the processor or the system.
These chassis were tested in a thermal chamber set to 35°C.
