The value is calculated by Tcontrol minus a fixed value.

Quiet: A preset configuration that is set to keep the overall system quieter, but slightly warmer.įanless: Hides all fan control-related setup options.įan speed increases if the processor temperature exceeds this value. Each value can be user-configured.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. Options are from 20 to 100 percent in 10 percent increments.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). Optionįixed: Allows the fan speed to be set at a fixed speed and never change. See the table below for fan control definitions. Available settings can vary, depending on Intel NUC model. System fan control settings in BIOS can be changed to meet the needs of your system usage model.

Press F2 during start to enter BIOS Setup.

Follow these steps to view or change system fan control settings: The third wire provides feedback on the actual RPM of the fan.This document covers cooling and fan control options in BIOS Setup for Intel® NUC products. Fans with 4 wires are controlled through pulse width modulation (PWM), in theory a more efficient way of controlling the fan speed. See Lm_sensors for generic details.įans with 2 or 3 wires may have voltage regulation: higher voltage (typically up to 12 Volt) results in higher rotation per minute (RPM). Specific hardware may have specific needs with respect to kernel configuration.

Fans that allow their speed to be controlled.

A motherboard capable of regulating fan speeds.

A BIOS that allows users to control the fan speed.

Higher temperatures cause more wear on the electronics, resulting in a shorter lifespan.Ĭontrolling fan speed is not supported on all computers.

What if the program controlling the fans fails? The computer could overheat and parts could be destroyed.

There are two risks when manually controlling fan speeds: It is generally considered more safe to have the BIOS or dedicated hardware control the fans.
