Intel W790 Series BIOS Manual
The following items appear only when CPU Fan Profile is set to [Standard], [Silent],
[Turbo], or [Manual].
CPU Fan Step Up
Step up allows you to adjust the time delay before the fan rotation speed increases
(level 0 is an instantaneous change in speed). The higher the level, the slower the
change in speed, and may also result in less noise, but this will also cause slower
heat dissipation.
Configuration options: [Level 0] [Level 1] [Level 2] [Level 3] [Level 4] [Level 5]
CPU Fan Step Down
Step down allows you to adjust the time delay before the fan rotation speed decreases
(level 0 is an instantaneous change in speed). The higher the level, the slower the
change in speed, which may result in longer period with more noise.
Configuration options: [Level 0] [Level 1] [Level 2] [Level 3] [Level 4] [Level 5]
CPU Fan Speed Low Limit
Allows you to set the lower speed limit for assigned fan/pump. A warning message will
appear when the limit is reached; the warning message will not appear if
[Ignore] is
selected.
Configuration options: [Ignore] [200 RPM] [300 RPM] [400 RPM] [500 RPM] [600
RPM]
The following items appear only when CPU Fan Profile is set to [Manual].
CPU Fan Point4 Temperature
When the temperature source is lower than the temperature of P4, the duty cycle
will be determined according to the P3-P4 and the temperature source. When the
temperature source is higher than the temperature of P4, the fan will operate at the
duty cycle of P4. Use the <+> or <-> keys to adjust the temperature.
CPU Fan Point4 Duty Cycle (%)
When the temperature source is lower than the temperature of P4, the duty cycle
will be determined according to the P3-P4 and the temperature source. When the
temperature source is higher than the temperature of P4, the fan will operate at the
duty cycle of P4. Use the <+> or <-> keys to adjust the fan/pump duty cycle.
CPU Fan Point3 Temperature
When the temperature source is lower than the temperature of P3, the duty cycle
will be determined according to the P2-P3 and the temperature source. When the
temperature source is higher than the temperature of P3, the fan will operate at the
duty cycle of P3-P4. Use the <+> or <-> keys to adjust the temperature.
CPU Fan Point3 Duty Cycle (%)
When the temperature source is lower than the temperature of P3, the duty cycle
will be determined according to the P2-P3 and the temperature source. When the
temperature source is higher than the temperature of P3, the fan will operate at the
duty cycle of P3-P4. Use the <+> or <-> keys to adjust the fan/pump duty cycle.
