2.12 Thermal Considerations

CAUTION
The use of an Intel
®
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 27).
Figure 26a illustrates an omnidirectional airflow heatsink.
