Intel® Pentium® Dual-Core Processor and Intel® Pentium® 4 Processor 6x1
— For the Intel® Core™2 Duo Desktop Processor E6000Δ and E4000Δ sequences, Intel® Pentium® Dual-Core Processor E2000Δ sequence and Intel® Pentium® 4 Processor 6x1Δ sequence at 65 W

Depending on the type of system and the chassis characteristics, new system and component designs may be required to provide adequate cooling for the processor. The goal of this document is to provide an understanding of these thermal characteristics and discuss guidelines for meeting the thermal requirements imposed on single processor systems using the Intel® Core™2 Duo desktop processor E6000/E4000Δ sequences, Intel® Pentium® Dual Core Processor E2000Δ sequence, and Intel® Pentium® 4 Processor 6x1Δ Sequence.

The concepts given in this document are applicable to any system form factor. Specific examples used will be the Intel enabled reference solution for ATX/uATX systems. See the applicable BTX form factor reference documents to design a thermal solution for that form factor.

64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel® 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information.

Δ Intel® processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See www.intel.com/products/processor_number/ for details.

‡ Not all specified units of this processor support Enhanced Intel SpeedStep® Technology. See the Processor Spec Finder at processorfinder.intel.com or contact your Intel representative for more information.

± Intel® Virtualization Technology (Intel® VT), Intel® Trusted Execution Technology (Intel® TXT), and Intel® 64 architecture require a computer system with a processor, chipset, BIOS, enabling software and/or operating system, device drivers and applications designed for these features. Performance will vary depending on your configuration. Contact your vendor for more information.

° Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.
