  2. Computer fan control - Wikipedia

    en.wikipedia.org/wiki/Computer_fan_control

    Increasing the voltage [4] over the default 12 V can be achieved by e.g. connecting the −12 V or −5 V power line instead of the ground wire in the fan connector, and by connecting the 5 V power line in the +12 V input of the fan connector. Through this procedure, 10, 17 and 24 V voltages can be achieved, with voltages exceeding 12 V being ...

    Connectors usually used for computer fans are the following: Three-pin Molex connector KK family This Molex connector is used when connecting a fan to the motherboard or other circuit board. It is a small, thick, rectangular in-line female connector with two polarizing tabs on the outer-most edge of one long side.

  4. Motherboard - Wikipedia

    en.wikipedia.org/wiki/Motherboard

    Most motherboards have connectors for additional computer fans and integrated temperature sensors to detect motherboard and CPU temperatures and controllable fan connectors which the BIOS or operating system can use to regulate fan speed. [5] Alternatively computers can use a water cooling system instead of many fans.

[32] ATX12V 4-pin power connector (also called the P4 power connector). A second connector that goes to the motherboard (in addition to the 24-pin ATX motherboard connector) to supply dedicated power for the ...

  6. Hot swapping - Wikipedia

    en.wikipedia.org/wiki/Hot_swapping

    Hot swapping is the replacement or addition of components to a computer system without stopping, shutting down, or rebooting the system; [1] hot plugging describes the addition of components only. [2] Components which have such functionality are said to be hot-swappable or hot-pluggable; likewise, components which do not are cold-swappable or ...

  7. System Management Bus - Wikipedia

    en.wikipedia.org/wiki/System_Management_Bus

    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 ...
