Table 68. REGISTER 0x63  ENHANCED ACOUSTICS REGISTER 2 (POWER-ON DEFAULT = 0x00) (Note 1)

Description

ACOU3
R/W
Assuming that PWMx is associated with the local temperature channel, these bits define the
maximum rate of change of the PWMx output for local temperature-related changes. Instead of
the fan speed jumping instantaneously to its newly determined speed, it ramps gracefully at the
rate determined by these bits. This feature ultimately enhances the acoustics of the fan.

Assuming that PWMx is associated with the Remote 2 temperature channel, these bits define
the maximum rate of change of the PWMx output for Remote 2 Temperature related
changes. Instead of the fan speed jumping instantaneously to its newly determined speed, it
ramps gracefully at the rate determined by these bits. This feature ultimately enhances the
acoustics of the fan.

When this bit is 1, smoothing is enabled on the Remote 2 temperature channel.
1.  This register becomes read-only when the Configuration Register 1 Lock bit is set to 1. Any further attempts to write to this register have no effect.
