Why does the CPU need thermal greases?

Thermal fat, also called thermal compound, helps the cooling sink in cooling the central processing unit (CPU). CPU is an integrated circuit responsible for starting your computer. The CPU consists of millions of small electronic "switches" stuck in the core. Every time the switch works, a small amount of heat is generated. With millions of these switches, they activate thousands of times every second, the heat is fast. For intensive programs such as computer gaming, the CPU works very hard and can warm up very much. Overclocking also increases thermal production. The lower surface of the radiator is designed to be extremely smooth to maximize contact with the surface to the surface with the CPU. However, the imperfections and pits in the CPU wafer allow small gaps that reduce the cooler efficiency. This is where the thermal tournament comes. It is a thin layer of one of the vase compounds that thermally binds the CPU and the cooling strap together. Fills any pits, gaps or imperfections that would allowAir pockets between chip and cooler.

Because thermal greases must make heat to be efficient, it is made of specific materials that do it quite well. Some types are better when doing or transmitting heat than others. Dear heat fat contains silver particles for maximum efficiency, while cheap compounds are based on silicon. Ceramic fat is a middle -class mixture; One remarkable brand overcomes silver compounds according to many independent tests.

with properly installed cooling sink using this material to maximize the contact with the heat withdraws from the chip and stretched up into the fins of the sink, where it is scattered by the fan. CPU should never be operated without heat and cooler. Temperature can quickly lift the core, which is non -functional.

CPU sold with a radiator and fan in a retail box include thermal fat, often in the form of thiné thermal pads. In most cases, the CPU warranty depends on the use of the supplied thermal pad, cooler and fan. If you buy a CPU and supply your own cooler and fan, do not forget to buy thermal fat and carefully shop for accompanying instructions.
