A heat sink (aluminum) with its heat pipes (copper) and fan (black) A heat sink (also commonly spelled heatsink, [1]) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of ...
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.
Noctua is an Austrian computer hardware manufacturer of CPU coolers and computer fans with a primary focus on the enthusiast market. The company's inception occurred in 2005 through a joint venture partnership between the Austrian company Rascom Computer distribution Ges.m.b.H., established in August 2000, [2] and the Taiwanese cooling specialist Kolink International Corporation.
CPU heat sink with fan attached A heat sink (aluminium) incorporating a heat pipe (copper) All electronic devices and circuitry generate excess heat and thus require thermal management to improve reliability and prevent premature failure. The amount of heat output is equal to the power input, if there are no other energy interactions. [1]
This heatsink is designed with the cooling capacity matching the CPU’s TDP. Thermal Design Power ( TDP ), also known as thermal design point , is the maximum amount of heat that a computer component (like a CPU , GPU or system on a chip ) can generate and that its cooling system is designed to dissipate during normal operation at a non-turbo ...
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.
Thermal paste (also called thermal compound, thermal grease, thermal interface material (TIM), thermal gel, heat paste, heat sink compound, heat sink paste or CPU grease) is a thermally conductive (but usually not electrically conductive) chemical compound, which is commonly used as an interface between heat sinks and heat sources such as high ...
A radiator is more efficient than a standard CPU or GPU heatsink/air cooler at removing heat because it has a much larger surface area. Installation of a water block is also similar to that of a heatsink, with a thermal pad or thermal grease placed between it and the device being cooled to aid in heat conduction.
