System 460W Redundant Power Supplies (CRPS) operate in spread-core flow conditions (positive pressure
to the power supply's inlet) and incorporate a 40mm fan for its own thermal management. To ensure PS
thermal protection under all operating conditions the fan speed control has a closed loop algorithm based
on both the critical component temperature and the ambient temperature (inlet temperature). The PS over
Temperature Protection (OTP) protects against over temperature conditions created by the loss of fan
cooling or excessive ambient temperature. In an OTP condition the PS will shut down and restore power

Intel Corporation server boards contain a number of high-density VLSI and power delivery components that need adequate airflow to
cool. Intel ensures through its own chassis development and testing that when Intel server building blocks are used together, the fully
integrated system will meet the intended thermal requirements of these components. It is the responsibility of the system integrator who
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.
