Rca (°C/W) = Thermal resistance of the Heat sink, between the case of the CPU and the ambient air. Tc = Maximum allowed temperature of the CPU's case (ensuring full performances). Ta = Maximum expected ambient temperature at the inlet of the Heat sink fan. All these parameters are linked together by the following equation:
A heat sink is not a device with the "magical ability to absorb heat like a sponge and send it off to a parallel universe". [2] Natural convection requires free flow of air over the heat sink. If fins are not aligned vertically, or if fins are too close together to allow sufficient air flow between them, the efficiency of the heat sink will ...
Other major uses include fast video cards, which contain graphics processing units, and power supplies. In laptops, the LCD 's backlight also uses a significant portion of overall power. While energy-saving features have been instituted in personal computers for when they are idle, the overall consumption of today's high-performance CPUs is ...
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.
Generally, forced convection heat sink thermal performance is improved by increasing the thermal conductivity of the heat sink materials, increasing the surface area (usually by adding extended surfaces, such as fins or foam metal) and by increasing the overall area heat transfer coefficient (usually by increase fluid velocity, such as adding ...
The Xbox 360 technical specifications describe the various components of the Xbox 360 video game console.. The console features a port on the top when vertical (left side when horizontal) to which a custom-housed hard disk drive unit can be attached in sizes of either 20, 60, 120, 250, 320, 500 GB; [1] and as of April 2015 all 2.5" SATA Hard Drives up to 2 TB, [2] [3] the user can use the ...
A water block is the watercooling equivalent of a heatsink. It is a type of plate heat exchanger and can be used on many different computer components, [1]: 186 including the central processing unit (CPU), GPU, PPU, and northbridge chipset on the motherboard. There are also Monoblocks on the market that are mounted on PC motherboards and cover ...
A CPU shim. A CPU shim (also called CPU spacer) is a shim used between the CPU and the heat sink in a computer. Shims make it easier and less risky to mount a heatsink on the processor because it stabilizes the heatsink, preventing accidental damaging of the fragile CPU packaging. [1] They help distribute weight evenly over the surface.
