power consumption. If the altitude is known, higher altitude is recommended in order to provide
sufficient cooling. The default setting is [301m – 900m].
12.2.3 Set Fan Profile
[Performance] and [Acoustic] fan profiles are available to select. The Acoustic mode offers best
acoustic experience and appropriate cooling capability covering mainstream and majority of the
add-in cards. Performance mode is designed to provide sufficient cooling capability covering all
kinds of add-in cards on the market. The default setting is [Performance].
12.2.4 Fan PWM Offset
This feature 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].
12.2.5 Quiet Fan Idle Mode
This feature can be [Enabled] or [Disabled]. If enabled, the fan will either stop or shift to a lower
speed when the aggregate sensor temperatures are satisfied indicating the system is at ideal
thermal/light loading conditions. When the aggregate sensor temperature is not satisfied, the fan
will shift back to normal control curves. If disabled, the fan will never stop or shift into lower fan
speed, whether the aggregate sensor temperatures are satisfied or not. The default setting is
[Disabled].
Note: The effectiveness of the above features depends on the actual thermal characters of a
specific system. Refer to specific system for additional information.

Server System P4308CP4MHEN
12.3.1 Fan and HDD Configuration
The Intel
®
Server System P4308CP4MHEN consists of two 120x38mm system fans and two
passive CPU heatsinks providing cooling for all ingredients inside the enclosure. The two
120x38mm fans deliver different cooling capability and are not interchangeable.
All the fans are Pulse Width Modulated (PWM) 4 wire/pin compatible fans. The fan headers are
connected to motherboard with below sequence. Improper connection will potentially lead to
thermal risk or undesired acoustic.
