Intel® Desktop Board D865GRH Specification Update 3. Change to Thermal Considerations, Section 2.12 Section 2.12, Thermal Considerations will change in its entirety as follows: 2.12 Thermal Considerations CAUTION The use of an Intel® Pentium® 4 processor operating above 2.80 GHz with this Intel® desktop board requires the following: • A chassis with appropriate airflow to ensure proper cooling of the components on the board • A processor fan heatsink that meets the thermal performance targets for Pentium 4 processors operating above 2.80 GHz The use of an Intel Pentium 4 processor with 1 MB of L2 cache on this Intel desktop board requires the following: • A chassis with a maximum internal ambient temperature of 38 Degrees Celsius • A processor heatsink that provides omnidirectional airflow so that air is drawn across the processor voltage regulator area (item A in Figure 26). Figure 25a illustrates an omnidirectional airflow heatsink. Figure 25a. Omnidirectional Airflow Heatsink 6
