In Automatic (Auto) control mode, the fan speed will vary automatically based on thermal conditions and configuration. You may need to change the fan control settings if your usage model includes any of the following instances: Sustained file transfers for a long period Stress testing Benchmarking Sustained processor usage of 75 percent or higher, for a long period Other Fan Control Settings Option Description Fan Usage This parameter is always set for System fan control and there are no other options.Ĭontrol Mode This parameter specifies whether the fan will be controlled automatically or manually. The default settings may be modified in future BIOS revisions as Intel continues to fine-tune them to get the best tradeoff between cooling and fan acoustics. These settings help minimize fan noise while keeping the system properly cooled in a normal working environment.

Minimum Duty cycle () This parameter specifies the minimum duty cycle that outputs to the fan.ĭuty cycle increment (C) Fan speed increases by this percentage for each degree over the minimum temperature.

Minimum Temperature (C) Fan speed increases if the processor temperature exceeds this value. Quiet: A preset configuration that is set to keep the overall system quieter, but slightly warmer.

Option Description Fan Control Mode Fixed: Allows the fan speed to be set at a fixed speed and never change.Ĭustom: Allows the fan speed to be customized based on processor temperature, minimum duty cycle, and duty cycle increment (see Other Fan Control Settings, below).Ĭool: A preset configuration that keeps the overall system cooler, but slightly louder.īalanced: A preset configuration that is set to keep the overall system balanced between cool and quiet. System fan control settings in BIOS can be changed to meet the needs of your system usage model.
