Provides the smallest-in-class features while meeting USCAR performance requirements, these scoop-proof connectors offer more space and cost savings than unsealed, USCAR Class 2 competing equivalentsĬompared to other connectors, as well as reducing the mating force Offers premium housing features to prevent mis-mating, reduce terminal backout, reduce operator fatigue during assembly and aid in blind-mating applications The smallest to-date, fully isolated header that meets customers’ power needs while providing protection for the terminals in a small packageĪ genderless, 2.50mm pitch, single-terminal-and-housing connector system that reduces inventory, tooling and setup costs for low-power applications The UL-94V0-rated, Glow-Wire-compatible RAST Connector System family delivers a range of current ratings to offer design flexibility for a variety of home appliance and automotive lighting applications Provides a wide range of options including free-hanging or panel-mount housings and 18-30 AWG terminals Of course there is also a fan attached to the power supply, which is built into the power supply.The smallest-to-date automotive-grade sealed system in the industry, as well as the only receptacle offering a IP68-equivalent rating adhering to USCAR specifications In many cases the Chip-set may use a Heat-pipe and not require a fan. Some Motherboards may also support a fan for the chipset, my old AV8 Mother board has an NB-Fan. One fan in the front of the chassis and one on the rear panel. The ASUS Motherboard also has two other 3-wire fans. Pin 2 is the speed sensor and pin 1 controls the fan speed. The fan pin out shown below is the cpu Heat-sink fan on an ASUS P5N-E SLI Mother Board.Īlthough the cable only fits in the Molex one way, the Black wire is ground. Of course there are other possible fan pinouts Next review the ATX Motherboard specification. Many companies may use pinouts that differ from the pinout table above.įirst try to determine the pin out of the headers listed above from the material that shipped with the computer. Use this pin out tabel for the fan header as a guide only. Memory Module formats and manufacturers are listed on the Memory Module Manufacturers page.Ī few computer manufacturers may use non-standard or proprietary components in their systems. PC FanĪdditional Mother Board form factors and processor types are listed on No data on copper AWG wire size is provided here. Pin 3 may also be called 'Rotation' instead of 'Sensor' both meaning the same thing. I have also seen 3-wire cable assemblies running from the fan that used White, Red, Back. The pin out table above provides both the connector pinouts and wire colors for the cable assembly. The fan pin out below could also be called a SYSFAN, or System Fan. The only fan header specified in the ATX standard was optional, and was a 6-pin connector.Īlso, fans may be either 5 volt DC or 12 volt DC fans, the table below shows a 12 volt DC fan connection All other ATX header pinouts, or BTX motherboard header pinout. In many cases the Fan will run one wire to the three pin header shown below ,Īnd also use an additional Molex connector to provide power to the fan. Not all fans or mother boards control or power the fan assemblies the same way. The mating connector coming from the Fan cable uses Female sockets. However the 4-pin header is also some what common The Header attached to the mother board is normally a male 3-pin header w/ locking tab. This page provides the connector style and pinout for the Fan connector used on the ATX Motherboard.
