A computer fan is generally a fan inside a CPU. It help’s to cool down an entire system while It is on running. There are a lot different types of computer fans are available. There is a personal fan is available for processor. Generally, A cooling fan is uses to do active cooling. The cooling fan expel warm air from computer, inside and move air across a heat sink to cool a particular component. Generally a size of computer fan is 92mm, 120mm, 140mm or even 200-220mm. A computer fans takes power from 4 pin fan connectors. some computer fans are stylish comes with RGB lighting.
In earlier personal computers it is possible to cool most of components using passive cooling. Many modern computers have effective cooling system. To cool this components and draw cooler air over them. The fans which is attach to components using a combination of heat sink to increase the area of heat surface. Sometimes we can control a speed of built-in fan using computer’s BIOS. A user can even add additional components with knobs that set fans to different speeds. Before 1997, there is no external cooling fan is available so In IBM‘s PC cooling is available in PSU. Almost all warm air exhaust through PSU’s fan. The first external cooling fan is started to appear by 1997.
Generally A fans are use to move air through the computer case. The component inside the case cannot be quickly takeout heat if surroundings are too hot. A case fans placed as an intake fans, exhaust fans, expelling warm air through top or rear. In some ATX tower cases have one or more additional vents and mounting points. where one or more fans may be installed to blow cool air directly onto motherboard components. comparatively, As case fans are often the most readily visible form cooling on a PC. There are decorative fans are widely available with LEDs or UV plastic or with decorative grills. decorative fans and accessories are popular with some case modes.
While a power supply contains a fan with few exceptions. It is not to be uses with case ventilation. The hotter air of PSU is the hotter PSU gets. The temperature rises the conductivity of its components decrease. means PSU will converts more input electric energy into thermal energy. The cooling fan of PSU is spinning fast enough to keep the PSU supplied with comparatively cool air. Generally most PSU is bottom mounted in modern PCs or having its own dedicated intake and exhaust vents.
In general, This fan is used to cool the heat sink of central processing unit (CPU). Effective cooling of a heat source such as a large-scale integrated circuits requires a heatsink. Which may be cool by a fan. A use of a fan alone not prevent overheating of the single small chip.
Generally, It uses to cool the heatsink of the graphic processing unit (GPU) or the memory on graphics cards. The older fans don’t were not necessary because of there low power consumption. But most modern graphic cards are develops for 3D graphics and gaming needs dedicate cooling fans. Some higher powered cards can produce more heat than CPU so cooling is especially important.
A chipset fan is uses to cool the heatsink of the northbridge of a motherboard’s chipset. This fan is needed when the processor is overclocked and dissipates more power. As more feature of the fab is integrate into central processing unit. The role of cheapset is reduces the heat also reduces.
Fans may be mount next to harddisk drive for cooling purposes. Hard drives can produce heat over time, and are heat sensitive components. In some situations, natural cooling suffices, but in some cases fans may be required. It includes Faster spinning hard disks with greater heat production. Larger arrays of disks or any disks which enclosure or other locations they are mounted in cannot cool without fan air.
A case fan may be mounts with a radiator attach to the case. In laptops, a single blower fan cools a heatsink connects to both CPU and GPU using heat pipes. In gaming laptops and mobile workstations, two or more heavy duty fans needs.
