Computer cooling. A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
An embedded controller can have the following tasks: Receiving and processing signals from the keyboard [ 1] and the touchpad (including touchpad disable) Other buttons and switches (e.g., power button, laptop lid switch (received from hall sensor)) [ 2] Controlling access to the A20 line [ 3] Thermal measurement (CPU, GPU, Motherboard) and ...
At the top of the case is a fan controller. Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they generate. This is commonly accomplished by the motherboards ...
Power-on self-test. A power-on self-test ( POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
The Intelligent Platform Management Interface ( IPMI) is a set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system's CPU, firmware ( BIOS or UEFI) and operating system. IPMI defines a set of interfaces used by system administrators for ...
SMSC™ (now Microchip) Super I/O chip (FDC37M813) on IBM motherboard. Super I/O (sometimes Multi-IO) [ 1] is a class of I/O controller integrated circuits that began to be used on personal computer motherboards in the late 1980s, originally as add-in cards, later embedded on the motherboards. A super I/O chip combines interfaces for a variety ...
A power supply unit ( PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.
Southbridge (computing) On older personal computer motherboards, the southbridge is one of the two chips in the core logic chipset, handling many of a computer's input/output functions. The other component of the chipset is the northbridge, which generally handles onboard control tasks. A southbridge chipset handles functions such as USB, audio ...
