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.
In computing, the motherboard form factor is the specification of a motherboard – the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. Specifically, in the IBM PC compatible industry, standard form factors ensure that parts are interchangeable across competing vendors and generations of ...
AT (form factor) IBM PC AT System Board. This is the original AT motherboard on which the form factor was based. In the era of IBM compatible personal computers, the AT form factor comprises the dimensions and layout ( form factor) of the motherboard for the IBM AT. Baby AT motherboards are slightly smaller, measuring 8.5" by 13". [ 1]
An ATX motherboard. Comparison of some common motherboard form factors (pen for scale) ATX ( Advanced Technology Extended) is a motherboard and power supply configuration specification, patented by David Dent in 1995 at Intel, [ 1] to improve on previous de facto standards like the AT design. It was the first major change in desktop computer ...
A motherboard (also called mainboard, main circuit board, MB, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central ...
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 thermal design power ( TDP ), sometimes called thermal design point, is the maximum amount of heat generated by a computer chip or component (often a CPU, GPU or system on a chip) that the cooling system in a computer is designed to dissipate under any workload. Some sources state that the peak power rating for a microprocessor is usually 1 ...
