4. 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 30).
Figure 29a illustrates an omnidirectional airflow heatsink.
