The Intel
®
Server System R1000SPO product family is thermally designed and developed in compliance with
ASHRAE Class A2 environment guidance; however, there is extra thermal margin for all components in the
system, so ASHRAE Class A3 environment conditions can be thermally supported.
Note: ASHARE Class A3 – Includes operation up to 40°C for up to 900 hours per year. Refer to Appendix E for
detailed HTA guidance.
The installation and functionality of several system components are used to maintain system thermals. They
include three managed 40mm single rotor system fans, fans integrated into each installed power supply
module, an air duct, populated drive carriers, and a CPU heat sink. Drive carriers can be populated with a
storage device (SSD or Hard Disk Drive) or supplied drive blank.

Thermal Operation and Configuration Requirements
To keep the system operating within supported maximum thermal limits, the system must meet the
following operating and configuration guidelines:
The system is designed for sustained operation on ambient temperature up to 35°C (ASHRAE Class
A2)
All externally accessed drive bays must be populated. Drive carriers can be populated with a storage
device (SSD or HDD) or supplied drive blank
When the system is operating, the air duct must be installed at all times
The system top cover must be installed at all times when the system is in operation in order to have
proper air flow

Thermal Management Overview
In order to maintain the necessary airflow within the system, all of the previously listed components need to
be properly installed. For best system performance, the external ambient temperature should remain below
35°C and all system fans (all rotors) should be operational.
NOTE: All system fans are controlled independent of each other. The fan control system may adjust fan
speeds for different fans based on increasing/decreasing temperatures in different thermal zones within the
chassis.
In the event that system temperatures should continue to increase with the system fans operating at their
maximum speed, platform management may begin to throttle bandwidth of either the memory subsystem or
the processors or both, in order to keep components from overheating and keep the system operational.
Throttling of these subsystems will continue until system temperatures are reduced below preprogrammed
limits.
The power supply will be protected against over temperature conditions caused by excessive ambient
temperature. In an over-temperature protection condition, the power supply module will shut down.

Fan Speed Control
The baseboard management controller (BMC) supports monitoring and control of fan speed (RPM). Each fan
is associated with a fan speed sensor that detects fan failure.
