A computer fan is whatever fan inside, or attached to, a computer case used for active cooling. Fans are accustomed draw tank air into the case from the outside, boot out warm air from inside and move air across a high temperature sink to coolheaded a particular component. Both axial and sometimes centrifugal (blower/squirrel-cage) fans are put-upon in computers. Calculator fans commonly come in standard sizes, such as 120mm (most common), 140mm, 240mm, and smooth 360mm. Reckoner fans are powered and controlled using 3-pin or 4-PIN number fan connectors.

Usage of a cooling fan [edit]

While in earlier personal computers it was possible to cool most components using natural convection (passive voice cooling), many neo components require more operational activistic temperature reduction. To nerveless these components, fans are put-upon to go up heated melodic phrase away from the components and draw ice chest air complete them. Fans pledged to components are usually used in combination with a heat fall off to increase the area of heated surface in contact with the air, thereby improving the efficiency of cooling. Fan control is not always an automatic march. A computing device's BIOS can control the speed of the made-up-in fan scheme for the calculator. A exploiter can even supplement this occasion with additional cooling components OR connect a manual fan controller with knobs that unmoving fans to other speeds.[1]

In the IBM PC compatible commercialize, the computer's power supply unit (PSU) almost always uses an exhaust fan to expel warm zephyr from the PSU. Active cooling connected CPUs started to appear on the Intel 80486, and by 1997 was normal on all desktop processors.[2] Chassis or case fans, usually one wipe out devotee to expel het air from the rear and optionally an uptake fan to draw cooler publicize in direct the frontal, became common with the arrival of the Pentium 4 in tardive 2000.[2]

Applications [edit]

Suit fan [edit]

Fans from computer case – in advance and back

Fans are accustomed move aura through the computer case. The components inside the case cannot dissipate heat efficiently if the surrounding air is too hot. Case fans may be placed as intake fans, drawing cooler outside vent in through the front or bottom of the chassis (where it Crataegus oxycantha besides live drawn over the internal hard drive racks), operating theatre exhaust fans, expelling warm air through the top operating room rear. Some ATX tower cases have one or more additive vents and mounting points in the left-wing side dialog box where unmatched or more fans may be installed to burn out assuredness melody directly onto the motherboard components and elaboration cards, which are among the largest heat sources.

Standardised axial causa fans are 40, 60, 80, 92, 120, 140, 200 and 220 mm in width and length. As case fans are often the most readily visible form of cooling on a PC, decorative fans are widely available and may be lit with LEDs, ready-made of UV-oxidizable plastic, and/or plastered with cosmetic grilles. Decorative fans and accessories are popular with eccentric modders. Air filters are often used over intake fans, to forestall junk from entering the cause and clogging prepared the internal components. Heatsinks are especially vulnerable to being clogged raised, as the insulating gist of the dust will rapidly degrade the heatsink's ability to disperse fire u.

PSU fan [edit]

While the power supply (PSU) contains a fan with a few exceptions, IT is not to be secondhand for case ventilation. The hotter the PSU's intake air is, the hotter the PSU gets. As the PSU temperature rises, the conductivity of its internal components decrease. Decreased conductivity means that the PSU will convert more of the input electric energy into natural spring DOE (heating system). This cycle of increasing temperature and attenuated efficiency continues until the PSU either overheats, or its cooling fan is spinning instantaneous enough to hold on the PSU adequately supplied with relatively cool air. The PSU is mainly bottom-mounted in modern PCs, having its own sacred ingestion and exhaust vents, sooner with a dust filter in its intake vent.

CPU fan [edit]

Accustomed cool the C.P.U. (middle processing whole) heatsink. Effective cooling of a undiluted heat up source such as a sizeable-scale integrated racing circuit requires a heatsink, which may be cooled by a buff;[3] use of a devotee alone bequeath non prevent overheating of the runty chip.

Graphics carte devotee [blue-pencil]

Used to water-cooled the heatsink of the graphics processing unit or the memory happening graphics cards. These fans were non necessary on elder cards because of their depression major power dissipation, but most modern graphics card game designed for 3D art and gaming need their own dedicated cooling fans. Some of the higher powered card game can produce many heat than the CPU (dissipating heavenward to 350 Isaac Watts[4]), so efficacious cooling is especially important. Since 2010, graphics card game have been released with either axial fans, or a centrifugal fan also known as a blower, turbo or squirrel cage fan.

Chipset sports fan [edit]

Accustomed chilly the heatsink of the northbridge of a motherboard's chipset; this may be needed where the system double-decker is importantly overclocked and dissipates more power than as usual, just English hawthorn otherwise be unnecessary. As more features of the chipset are integrated into the processor, the office of the chipset has been reduced and the heat generation reduced also.

Hard drive cooling [edit]

Fans may be adorned next to operating theater onto a hard disc drive for cooling purposes. Steely drives can produce considerable heat over meter, and are heating-sensitive components that should non operate at excessive temperatures. In many an situations, natural convective cooling suffices, simply in some cases fans may constitute needed. These may include -

  • Faster-spinning touchy disks with greater ignite production. (As of 2011[update] inferior expensive drives revolved at speeds adequate to 7,200 RPM; 10,000 and 15,000 Revolutions per minute drives were available but generated to a greater extent passion.)
  • Large or dense arrays of disks (including server systems where disks are typically mounted densely)
  • Any disks which, due to the enclosure or other localization they are mounted in, cannot easily cool without fanned beam.

Fivefold purposes [edit]

A infinitesimal blower fan is used to direct air across a laptop computer computer's Processor tank.

A case fan Crataegus laevigata be affixed on a radiator attached to the case, simultaneously operating to cool a liquid cooling device's working graceful and to ventilate the case. In laptops, a unshared blower fan much cools a heat sink connected to both CPU and GPU victimization heat pipes. In gaming laptops and mobile workstations, ii or more heavily obligation fans Crataegus oxycantha be used. In rack-decorated servers, a single row of fans may lock to create an air flow through the chassis from front to bring up, which is directed aside passive ducts OR shrouds across individual components' heat sinks.

Separate purposes [edit]

Fans are, less commonly, used for other purposes so much as:

  • Water-cooling radiator transfers a great deal of wake, and radiator fans have large static pressure level (anti to pillowcase fans that have high airflow) for dissipating heat.
  • Laptop computers deficiency mammoth openings in the case for warm air to escape. The laptop may cost placed on a ice chest – fairly like a tray with fans built in – to ensure adequate temperature reduction.
  • Some high-end machines (including many servers) or when additional reliability is needed, other chips like SATA/SAS controller, high speed networking controllers (40Gbps Ethernet, Infiniband), PCIe switches, coprocessor card game (for example some Xeon Phi), some FPGA chips, south bridges are also actively cooled with a heatsink and a dedicated rooter. These can get on a main motherboard itself or A a separate add-on board, oft via PCIe card.
  • Expansion slot fan – a fan mounted in one of the PCI OR PCI Express slots, usually to supply additive chilling to the graphics card game, or to expanding upon cards in general.
  • Optical driving force fan – whatever internal CD and/or DVD burners included cooling fans.
  • Retentiveness devotee – modern computer memory can generate enough heat that active cooling may be necessary, usually in the form of small fans positioned above the memory chips. This applies especially when the memory is overclocked or overvolted,[5] operating theater when the memory modules include spry logic, such as when a system uses Fully Buffered DIMMs (FB-DIMMs).[6] However, with newer lower voltages in use, such arsenic 1.2v DDR4, this is less usually required than accustomed represent the case.[ cite needed ]. Nearly of the time memory modules, settled confining to Processor will receive enough of the air flow from the case or Mainframe devotee, even if the air from CPU fan and radiator is warm. If the main Mainframe is water system cooled, this small amount of airflow might make up missing, and extra care about some airflow in a case operating theatre a dedicated memory cooling is required. Unluckily most memory modules do non provide temperature monitoring to easily cadence it.
  • Sharp power voltage regulators (VRM) often using switch mode office supplies act yield some heat imputable world power losses, mostly in the power MOSFET and in an inductor (choke). These, especially in overclocking situations want active cooling buff together with heatsink. Nearly of the MOSFETs will operate right at very high temperature, but their efficiency will be lowered and possibly lifespan limited. Proximity of electrolytic capacitors to a source of heat, will decrease their lifetime considerably and end in a progressively higher power losses and eventual (ruinous) failure.[ citation needed ]

Physical characteristics [edit]

Imputable the low imperativeness, high volume air flows they create, most fans used in computers are of the axial flow type; centrifugal and crossflow fans character.[7] Two important functional specifications are the flow of air that can be touched, typically stated in box-shaped feet per minute of arc (CFM), and static pressure.[8] Given in decibels, the sound volume figure can be also very important for home and office computers; larger fans are generally quieter for the same CFM.

Many an gamers, case modders, and enthusiasts utilize fans lit with colored LED lights. Multi-partial fans are besides available. Colors and lighting patterns peradventur controlled or programmed via a RGB fan controller, similar to Christmas lights.

Dimensions [delete]

Fan sizes and similar screw golf hole spacing
Fan size (mm) Center of mounting hole spacing (mm)
40 32
50 40
60 50
70 60
80 71.5
92 82.5
120 105
140 124.5
200 154
220 170

The dimensions and mounting holes mustiness suit the equipment that uses the buff. Foursquare-framed fans are usually used, but round frames are also utilized, often and then that a larger fan than the mounting holes would otherwise allow can personify used (e.g., a 140 mm fan with holes for the corners of a 120 millimetre wholesome fan). The width of square fans and the diam of round ones are usually explicit in millimeters. The dimension given is the outside width of the fan, not the distance 'tween climb holes. Common sizes include 40 millimeter, 60 mm, 80 mm, 92 mm, 120 mm and 140 mm, although 8 mm,[9] 17 millimetre,[10] 20 millimeter,[11] 25 mm,[12] 30 mm,[13] 35 mm,[14] 38 mm,[15] 45 mm,[16] 50 mm,[17] 70 millimetre,[18] 200 mm, 220 millimetre,[19] 250 mm[20] and 360 millimeter[21] sizes are too available. Heights, or heaviness, are typically 10 mm, 15 millimeter, 25 mm or 38 mm.

Typically, paid 120 mm and 140 millimetre fans are used where cooling system requirements are demanding, as for computers utilised to play games, and for quieter operation at lower speeds. Larger fans are unremarkably used for cooling case, CPUs with large heatsink and ATX power supply. Square 80 millimeter and 92 millimetre fans are used in fewer tight applications, operating theatre where larger fans would not be mixable. Smaller fans are unremarkably used for chilling CPUs with small heatsink, SFX power supply, graphics cards, northbridges, etc.

Rotational speed [edit]

The speed of revolution (mere in revolutions per minute, RPM) together with the static pressure square off the airflow for a given fan. Where racket is an issue, larger, slower-turning fans are quieter than littler, faster fans that can move the same airflow. Fan resound has been found to be roughly proportional to the fifth part power of fan speed; halving the speed reduces the randomness past about 15 dB.[22] Axial fans English hawthorn rotate at speeds of up to or so 38,000 rpm for small sizes.[23]

Fans may be priest-ridden past sensors and circuits that trim their speed when temperature is non high, leading to quieter operation, longer life, and lower power consumption than fixed-speed fans. Fan lifetimes are usually quoted under the presumption of running at maximum speed and at a geostationary ambient temperature.

Air pressure and rate of flow [edit]

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 pres is more important than flow of air in CFM when choosing a fan for exercise with a heatsink. The relative importance of static pressure depends on the level to which the air flow is restricted past geometry; static pressure becomes more important as the spacing betwixt heatsink fins decreases. Static pressure is usually expressed in either mm Hg or mm H2O.

Bearing types [edit]

The type of bearing misused in a fan can affect its execution and noise. Most computer fans habit single of the following bearing types:

  • Sleeve bearings role two surfaces lubricated with oil or grease as a friction contact. They often consumption porous sintered sleeves to be self-lubricating, requiring lone infrequent upkeep operating room replacement. Sleeve bearings are less durable at higher temperatures As the contact surfaces wear and the lubricant dries up, in time leading to failure; however, lifetime is similar to that of ball-bearing types (generally a little less) at relatively low close temperatures.[24] Sleeve bearings may embody more likely to fail at high temperatures, and may perform poorly when mounted in any orientation other than vertical. The typical life of a sleeve-bearing devotee may be around 30,000 hours at 50 °C (122 °F). Fans that use arm bearings are generally cheaper than fans that use clump bearings, and are quieter at lower speeds early in their liveliness, but can become reedy arsenic they age.[24]
  • Pillage bearings are exchangeable to sleeve bearings, just are quieter and have almost Eastern Samoa much lifespan arsenic ball bearings. The productive has a spiral furrow in it that pumps fluid from a reservoir. This allows them to glucinium safely mounted with the cheat horizontal (dissimilar sleeve bearings), since the fluent being wired lubricates the top of the jockey.[25] The pumping also ensures sufficient lubricant on the shaft, reducing noise, and increasing lifespan.
  • Mobile bearings (OR "Fluid Projectile Bearing", FDB) have the advantages of near-silent operation and high life expectancy (though not longer than ball bearings), but tend to be Sir Thomas More expensive.
  • Ball bearings: Though generally more expensive than fluid bearings, ball bearing fans coiffure non put u the same orientation limitations as sleeve bearing fans, are more durable at higher temperatures, and are quieter than sleeve-bearing fans at high rotation speeds. The veritable lifespan of a ball bearing fan may be all over 60,000 hours at 50 °C (122 °F).[24]
  • Charismatic bearings operating theatre maglev bearings, in which the fan is repelled from the bearing past magnetism.

Connectors [edit]

Three-pin connexion on a computer fan

Connectors commonly used for computer fans are the following:

Trine-pin Molex connector KK family
This Molex connector is used when connecting a fan to the motherboard or otherwise racing circuit board. Information technology is a small, thick, rectangular in-line female connector with two polarizing tabs connected the outer-most edge of uncomparable long side. Pins are square and on a 0.1 inch (2.54 millimeter) pitch. The three pins are used for ground, +12 V power, and a tachometer signaling. The Molex part act of receptacle is 22-01-3037. The Molex part number of the individual crimp contacts is 08-50-0114 (tin plated) or 08-55-0102 (semi gilt plated). The matching PCB header Molex part number is 22-23-2031 (put u plated) or 22-11-2032 (gold plated). A corresponding wire stripper and crimping tools are also mandatory.
Four-pin Molex connector KK family
This is a special var. of the Molex KK connexion with four pins but with the locking/polarization features of a ternary-pin connective. The additional peg is used for a pulse-width modulation (PWM) signal to provide covariant stop number control.[26] These can be obstructed into 3-pin headers, but will lose their rooter speed control. The Molex part number of receptacle is 47054-1000. The Molex part number of individual frizz contacts is 08-50-0114. The Molex part number of the header is 47053-1000.
Four-pin Molex connector
This connecter is used when connecting the fan directly to the mightiness supply. It consists of two wires (yellow/5 V and melanise/basis) leading to and splicing into a vast in-line quartet-pin male-to-female Molex connector. The unusual two wires of the connector provide 12V (red) and establish (black too), and are not used in this incase. This is the same connector as used connected petrous drives ahead the SATA became canonic.
Three-pin Molex connector PicoBlade family
This connector is used with notebook fans or when conjunctive the devotee to the video card.
Dingle proprietary
This proprietary Dell connector is an expansion of a simple three-pin female IC connexion away adding two tabs to the middle of the connector on one side and a lock-tab on the different side. The sized and spacing of the immobilise sockets is identical to a textbook three-thole female Cardinal connector and three-pin Molex connector. Some models have the wiring of the white wire (speed sensor) in the middle, whereas the standardized 3-pin Molex connector requires the segregated wire as pin #3, thus compatibility issues may exist.
Others
Some reckoner fans use two-pin connectors, of various designs.

Alternatives [edit]

If a rooter is not desirable, because of noise, dependableness, or situation concerns, there are some alternatives. Some betterment can be achieved by eliminating all fans except one in the mogul supply which also draws hot air knocked out of the case.[27]

Systems can live designed to use hands-off cooling alone, reducing haphazardness and eliminating tossing parts that May fail. This can glucinium achieved away:

  • Natural convection cooling: with kid gloves designed, correctly oriented, and sufficiently large heatsinks force out dissipate up to 100 W by spontaneous convection alone
  • Heatpipes to transfer heat out of the case
  • Undervolting or underclocking to reduce power dissipation
  • Submersive liquid cooling, placing the motherboard in a non-electrically conductive fluid, provides excellent convection cooling and protects from humidness and water without the call for for heatsinks or fans. Special care must be taken to assure compatibility with adhesives and sealants victimized on the motherboard and ICs. This result is used in some international environments such as wireless equipment located in the wild.[ citation needed ]

Other methods of cooling include:

  • Water temperature reduction
  • Mineral inunct
  • Melted nitrogen
  • Refrigeration, e.g. by Peltier issue devices
  • Ionic wind chilling is being researched, whereby air is emotional by ionizing air 'tween cardinal electrodes. This replaces the fan and has the vantage of zero moving parts[28] and little noise.[29]
