How to Recognize a Thermally Advantaged Chassis

Thermally advantaged chassis (TAC) version 1.1: A chassis that has been designed to meet the required thermal specification of a 38°C fan inlet temperature for the Intel® Celeron® D Processor, Intel Celeron® Processor 4xx Series, Intel® Pentium® 4 Processor, Intel® Pentium® 4 Processor Extreme Edition, Intel® Pentium® Dual-Core Processor E2100 Series, and Intel® Core™2 Duo Desktop Processors based on 65nm and 90nm. 

To meet the thermal specification requirements of the Intel Pentium D, Intel® Core™2 Extreme, and the lntel® Core™2 Quad Processors use a chassis that has been designed to maintain an internal ambient temperature below 39°C.

A thermally advantaged chassis can be recognized by a hollow tube attached to the side panel called a chassis air guide which has flared ends. This tube will funnel cool air towards the processor. Its reliance on the internal system fans to guide air across the processor and other system components is achieved through a ventilation hole within the side panel that is required in order to function properly.

See the processor's datasheet for more information. A 38oC TA chassis is considered the best method to achieve this requirement.
