Smart Cooling

Function Description

The Smart Cooling page allows you to query and set the fan speed adjustment policy for a server.

  • The iBMC versions earlier than V334 support the energy saving mode, low noise mode, high performance mode, and custom mode.
  • From iBMC V334, the liquid-cooled servers support only the liquid cooling mode and custom mode, and the air-cooled servers support the energy saving mode, low noise mode, high performance mode, and custom mode.
NOTE:
  • The 2288H V5 supports smart cooling from iBMC V260.
  • The 2488 V5, 2488H V5, and 5885H V5 servers support smart cooling from iBMC V296.
  • The RH1288 V3 and 1288H V5 support smart cooling from iBMC V308.
  • The 2288C V5 supports smart cooling from iBMC V334.
  • If the fan adjustment mode is Manual, all the settings on the Smart Cooling page will take effect only when the fan adjustment mode changes to Auto.

GUI

Choose Power from the main menu, and select Smart Cooling from the navigation tree.

Parameter Description

Table 3-39 Smart Cooling parameters

Parameter

Description

Energy saving mode

Adjusts the server fans to operate at a certain speed based on the system load and heat dissipation to minimize the power consumption.

Low noise mode

Enables the fans to operate at the minimum speed that meets heat dissipation requirements to reduce noise.

High performance mode

Enables the fans to operate at high speed to ensure optimal cooling of the key components and achieve high system performance.

Liquid cooling mode

Enables the fans to operate at low speed and noise without affecting the system performance. It is the default fan adjustment mode for liquid-cooled servers.

Custom mode

Allows users to set the target CPU temperature and the fan speeds corresponding to different inlet temperature ranges.

  • The CPU Target Temperature, Air Outlet Target Temperature, and Fan Speed parameters are available only when Custom mode is selected.
  • The system provides the value range of CPU Target Temperature and Air Outlet Target Temperature based on the current load and heat dissipation of the server. Set this parameter based on the value range displayed.
  • The Fan Speed value range is 20 to 100. The fan speed corresponding to a higher temperature range must be greater than the fan speed corresponding to a lower temperature range.
NOTE:
  • During CPU replacement, if the highest operating temperature of the new CPU is lower than the current value of CPU Target Temperature, the iBMC automatically changes the value of CPU Target Temperature to the maximum temperature allowed by the new CPU.

Procedure

NOTE:

For example, to set the smart cooling mode to Custom mode, perform the following steps:

  1. Select Custom mode.
  2. Set CPU Target Temperature based on the value range displayed.
  3. Set the fan speeds corresponding to the inlet temperature ranges.
  4. Click Save.

    The system displays "Specifying custom parameter values may result in insufficient heat dissipation."

  5. Click Yes.

    If "Operation successful" is displayed, the smart cooling mode is set successfully.
