A fan controller with LEDs indicating fan status and potentiometers and switches to control fan speeds. Another method, popular with PC hardware enthusiasts, is the manual fan speed controller. They can be mounted in an expansion slot or a 5.25" or 3.5" drive bay or come built into a computer's case. Using switches or knobs, attached fans can ...
With 3-pin fans, either fixed inline resistors or diodes, or commercial fan controllers, such as the Zalman Fanmate, can be used. Software like speedfan or Argus Monitor may allow fan speed control. Many newer motherboards support pulse-width modulation (PWM) control, allowing the fan speed to be set in the BIOS or with software.
SpeedFan is a system monitor for Microsoft Windows that can read temperatures, voltages and fan speeds of computer components. [3] It can change computer fan speeds depending on the temperature of various components. [1] [4] The program can display system variables as charts and as an indicator in the system tray.
This is a special variant of the Molex KK connector with four pins but with the locking/polarisation features of a three-pin connector. The additional pin is used for a pulse-width modulation (PWM) signal to provide variable speed control. [26] These can be plugged into 3-pin headers, but will lose their fan speed control.
Controlling access to the A20 line [3] Thermal measurement (CPU, GPU, Motherboard) and response including fan control, CPU and GPU throttling, and emergency shutdown in response to rising temperatures; Power management, including control voltage regulator module
The ME is colloquially categorized as ring −3, below System Management Mode (ring −2) and the hypervisor (ring −1), all running at a higher privilege level than the kernel (ring 0). The Intel Management Engine ( ME ), also known as the Intel Manageability Engine , [ 1 ] [ 2 ] is an autonomous subsystem that has been incorporated in ...

It is derived from I²C for communication with low-bandwidth devices on a motherboard, especially power related chips such as a laptop's rechargeable battery subsystem (see Smart Battery System and ACPI). [1] Other devices might include external master hosts, temperature sensor, fan or voltage sensors, lid switches, clock generator, and RGB ...
