Cpu cooling is a computer hardware process that involves dissipating heat generated by the central processor unit (CPU). A CPU cooler typically consists of a thermal paste, a CPU fan and a heat sink. When correctly installed and used, this cooling mechanism can significantly reduce CPU temperatures.
A thermal paste is a material used to improve the transfer of heat from the processor to the cooling system. The thermal paste is a thin layer of material that is applied directly to the CPU. This material is often made of a blend of metals that have high thermal conductivity. This allows for a better heat transfer between the CPU and the heat sink than standard thermal grease.
The CPU fan moves air across the heat sink and dissipates the heat from the CPU by convection. This is usually done by drawing cool air in from the case grille and releasing warm air out of the top/back of the case. Using multiple fans that blow in different directions can help to create an even flow of air throughout the case.
Another way to dissipate heat from the CPU is by using a jet impingement cooling technique. This method involves flowing a coolant over the CPU surface, which is typically a copper or aluminum baseplate, to form a jet of liquid. This type of cooling is effective at removing large amounts of local heat, and can also be combined with micro-channel or two-phase cooling to increase the efficiency of CPU cooling.
