120mm vs 140mm fans - What’s the difference? Probing Paul #28

Views Read Edit View history. The type of bearing used in a fan can affect its performance and noise. Air filters are often used over intake fans, to prevent dust from entering the case and clogging up the internal components. Fan lifetimes are usually quoted under the assumption of running at maximum speed and at a fixed ambient temperature. Hidden categories: Articles containing potentially dated statements from All articles containing potentially dated statements All articles with unsourced statements Articles with unsourced statements from November Articles with unsourced statements from April Articles with unsourced statements from January Commons category link is on Wikidata. Namespaces Article Talk. Decorative fans and accessories are popular with case modders. To cool these components, fans are used to move heated air away from the components and draw cooler air over them. These may include -. The components inside the case cannot dissipate heat efficiently if the surrounding air is too hot. Fans may be mounted next to or onto a hard disk drive for cooling purposes. Retrieved Upgrading and Repairing PCs. Case fans may be placed as intake fans , drawing cooler outside air in through the front or bottom of the chassis where it may also be drawn over the internal hard drive racks , or exhaust fans , expelling warm air through the top or rear. Most computer fans use one of the following bearing types:. From Wikipedia, the free encyclopedia. Fan control is not always an automatic process. Active cooling on CPUs started to appear on the Intel , and by was standard on all desktop processors. Many gamers, case modders , and enthusiasts utilize fans illuminated with colored LED lights. A user can even supplement this function with additional cooling components or connect a manual fan controller with knobs that set fans to different speeds. As more features of the chipset are integrated into the central processing unit , the role of the chipset has been reduced and the heat generation reduced also. Fans are used to move air through the computer case. Heatsinks are especially vulnerable to being clogged up, as the insulating effect of the dust will rapidly degrade the heatsink's ability to dissipate heat. Games and Gears Elite. Some improvement can be achieved by eliminating all fans except one in the power supply which also draws hot air out of the case. In rack-mounted servers, a single row of fans may operate to create an airflow through the chassis from front to rear, which is directed by passive ducts or shrouds across individual components' heat sinks. As the PSU temperature rises, the conductivity of its internal components decrease. The relative importance of static pressure depends on the degree to which the airflow is restricted by geometry; static pressure becomes more important as the spacing between heatsink fins decreases. Fans attached to components are usually used in combination with a heat sink to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling. Hard drives can produce considerable heat over time, and are heat-sensitive components that should not operate at excessive temperatures. Centrifugal Fans". This can be achieved by:. Retrieved 1 April Archived from the original on 2 April UK Health and Safety Executive. Systems can be designed to use passive cooling alone, reducing noise and eliminating moving parts that may fail. Wikimedia Commons has media related to Computer cooling fans.{/INSERTKEYS}{/PARAGRAPH} Multi-colored fans are also available. Due to the low pressure, high volume air flows they create, most fans used in computers are of the axial flow type; centrifugal and crossflow fans type. The PSU is mainly bottom-mounted in modern PCs, having its own dedicated intake and exhaust vents, preferably with a dust filter in its intake vent. {PARAGRAPH}{INSERTKEYS}A computer fan is any fan inside, or attached to, a computer case used for active cooling. Since , graphics cards have been released with either axial fans , or a centrifugal fan also known as a blower, turbo or squirrel cage fan. The dimension given is the outside width of the fan, not the distance between mounting holes. If a fan is not desirable, because of noise, reliability, or environmental concerns, there are some alternatives. The width of square fans and the diameter of round ones are usually stated in millimeters. Effective cooling of a concentrated heat source such as a large-scale integrated circuit requires a heatsink, which may be cooled by a fan; [3] use of a fan alone will not prevent overheating of the small chip. Fans are used to draw cooler air into the case from the outside, expel warm air from inside and move air across a heat sink to cool a particular component. While the power supply PSU contains a fan with few exceptions, it is not to be used for case ventilation. Help Community portal Recent changes Upload file. This cycle of increasing temperature and decreased efficiency continues until the PSU either overheats, or its cooling fan is spinning fast enough to keep the PSU adequately supplied with comparatively cool air. September Archived from the original PDF on Categories : Computer hardware cooling Fans. In many situations, natural convective cooling suffices, but in some cases fans may be required. See also: Quiet PC. Que Publishing. Main article: Mechanical fan. Computer fans commonly come in standard sizes, and are powered and controlled using 3-pin or 4-pin fan connectors. Square-framed fans are usually used, but round frames are also used, often so that a larger fan than the mounting holes would otherwise allow can be used e. Where noise is an issue, larger, slower-turning fans are quieter than smaller, faster fans that can move the same airflow. Some ATX tower cases have one or more additional vents and mounting points in the left side panel where one or more fans may be installed to blow cool air directly onto the motherboard components and expansion cards, which are among the largest heat sources. How-To Geek. Used to cool the heatsink of the graphics processing unit or the memory on graphics cards. The speed of rotation specified in revolutions per minute , RPM together with the static pressure determine the airflow for a given fan. Used to cool the heatsink of the northbridge of a motherboard's chipset ; this may be needed where the system bus is significantly overclocked and dissipates more power than as usual, but may otherwise be unnecessary. Fans may be controlled by sensors and circuits that reduce their speed when temperature is not high, leading to quieter operation, longer life, and lower power consumption than fixed-speed fans. Decreased conductivity means that the PSU will convert more of the input electric energy into thermal energy heat. Pelonis Technologies. A fan with high static pressure is more effective at forcing air through restricted spaces, such as the gaps between a radiator or heatsink; static pressure is more important than airflow in CFM when choosing a fan for use with a heatsink. Smaller fans are usually used for cooling CPUs with small heatsink, SFX power supply, graphics cards, northbridges, etc. Play media. Static pressure is usually stated in either mm Hg or mm H 2 O. These fans were not necessary on older cards because of their low power dissipation, but most modern graphics cards designed for 3D graphics and gaming need their own dedicated cooling fans. Wikimedia Commons. The dimensions and mounting holes must suit the equipment that uses the fan. Used to cool the CPU central processing unit heatsink. Games and Gears. While in earlier personal computers it was possible to cool most components using natural convection passive cooling , many modern components require more effective active cooling. A case fan may be mounted on a radiator attached to the case, simultaneously operating to cool a liquid cooling device's working fluid and to ventilate the case. Download as PDF Printable version.
