Note: Intel
®
Corporation server boards support peripheral components and can contain a
number of high-density VLSI and power delivery components that need adequate airflow to cool.
Intel’s own chassis are designed and tested to meet the intended thermal requirements of these
components when the fully integrated system is used together. It is the responsibility of the
system integrator that chooses not to use Intel
®
developed server building blocks to consult
vendor datasheets and operating parameters to determine the amount of airflow required for
their specific application and environmental conditions. Intel Corporation cannot be held
responsible if components fail or the server board does not operate correctly when used outside
any of its published operating or non-operating limits.
