System Thermal Solution Considerations
2.4.1
Chassis Thermal Design Capabilities
The Intel reference thermal solutions and Intel Boxed Processor thermal solutions
assume that the chassis delivers a maximum T
A
at the inlet of the processor fan
heatsink. The following tables show the T
A
requirements for the reference solutions
and Intel Boxed Processor thermal solutions.

Intel reference designs (E18764-001) for ATX assume the use of the thermally
advantaged chassis (refer to Thermally Advantaged Chassis (TAC) Design Guide for
TAC thermal and mechanical requirements). The TAC 2.0 Design Guide defines a new
processor cooling solution inlet temperature target of 40 °C. The existing TAC 1.1
chassis can be compatible with TAC 2.0 guidelines.

2.4.2
Improving Chassis Thermal Performance
The heat generated by components within the chassis must be removed to provide an
adequate operating environment for both the processor and other system
components. Moving air through the chassis brings in air from the external ambient
environment and transports the heat generated by the processor and other system
components out of the system. The number, size and relative position of fans and
vents determine the chassis thermal performance, and the resulting ambient
temperature around the processor. The size and type (passive or active) of the
thermal solution and the amount of system airflow can be traded off against each
other to meet specific system design constraints. Additional constraints are board
layout, spacing, component placement, acoustic requirements, and structural
considerations that limit the thermal solution size. For more information, refer to the
