Server System H2000WP Family TPS Product Overview

2.3.3 Altitude

This option is used to select the proper altitude that the system will be used in. Available

settings include: [300m or less], [301m-900m], [901m-1500m], [Above 1500m].

Selecting an altitude range that is lower than the actual altitude the system will be operating at,

can cause the fan control system to operate less efficiently, leading to higher system thermals

and lower system performance. If the altitude range selected is higher than the actual altitude

the system will be operating at, the fan control system may provide better cooling but with

higher acoustics and higher fan power consumption. If the altitude is not known, selecting a

higher altitude is recommended in order to provide sufficient cooling.

2.3.4 Set Fan Profile

This option is used to set the desired Fan Profile. Available settings include:

[Performance] and [Acoustic].

The Acoustic mode offers the best acoustic experience and appropriate cooling capability

covering the mainstream and the majority of the add-in cards used. Performance mode is

designed to provide sufficient cooling capability covering all kinds of add-in cards on the market.

2.3.5 Fan PWM Offset

This option is reserved for manual adjustment to the minimum fan speed curves. The valid

range is from [0 to 100] which stands for 0% to 100% PWM adding to the minimum fan speed.

This feature is valid when Quiet Fan Idle Mode is at Enabled state. The default setting is [0].

2.3.6 Quiet Fan Idle Mode

This feature can be [Enabled] or [Disabled]. If enabled, the fans will either shift to a lower

speed or stop when the aggregate sensor temperatures are satisfied, indicating the system is at

ideal thermal/light loading conditions. When the aggregate sensor temperatures are not satisfied,

the fans will shift back to normal control curves. If fans are disabled, they will never shift into

lower fan speeds or stop, regardless of whether the aggregate sensor temperatures are

satisfied or not. The default setting is [Disabled].

Note: The above feature may or may not be in effect and depends on the actual thermal

characteristics of the specified system.

2.3.7 Thermal Sensor Input for Fan Speed Control

The BMC uses various IPMI sensors as inputs to fan speed control. Some of the sensors are

actual physical sensors and some are virtual sensors derived from calculations.

The following IPMI thermal sensors are used as input to fan speed control:

 Front Panel Temperature Sensor

 Server board Temperature Sensor

 Processor Margin Sensors

3, 5, 6

 DIMM Thermal Margin Sensors

3,5

 Exit Air Temperature Sensor

1, 4, 8

Revision 1.6 Intel order number: G52418-006 11
