Smart Cooling

Smart Cooling

Function Description

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

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:
  • From iBMC V334, the CH121 V5 and CH121L V5 support smart cooling.
  • 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 3-34 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

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 the fan speeds corresponding to the inlet temperature ranges.
  3. Click Save.

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

  4. Click Yes.

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