What connector do PC fans use?

Power connections Most cooling fans will connect to a PC with a standard connector of some sort. Modern systems will typically use 3-pin or 4-pin dedicated fan headers, though standard MOLEX 4-pin peripheral connectors are also used. From left to right: A 3-pin connector, a 4-pin connector and a MOLEX connector.

What are the 3 wires on a PC fan?

A three pin connector is basically power (5/12 volt), ground, and signal. The signal wire measures how fast the fan is moving without any controls for the fan speed. With this type, fan speed is typically controlled by increasing or decreasing the voltage over the power wire.

What are the 4 wires on a PC fan?

However, the 4-wire fan is a little different as it has the fourth ‘control’ wire to input a signal to the fan that commands it to speed up or speed down….4-wire fans explained.

PIN WIRE COLOR FUNCTION
1 Black GND (0V)
2 Yellow +12V
3 Green Sense/Tach
4 Blue Control/PWM

What kind of power connector do I need for a CPU fan?

Chassis and CPU fans may use either 3-pin or 4-pin power connectors. 3-pin connectors are usually used for the smaller chassis fans with lower power consumption.

What is the name of this connector from a fan?

Thanks for the help. The three-pin version (non-PWM) is referred to by some computer technicians as a “TX3 connector,” but this is something of a misnomer (similar to the moniker “Molex connector,” referring to the once-common 4-pin ATX power connectors originally produced by AMP).

Which is better 3 pin or 4 pin fan connectors?

connectors. 3-pin connectors are usually used for the smaller chassis fans with lower power consumption. 4-pin connectors are usually used by CPU fans with higher power consumption. Fans and on-board fan headers are backwards compatible. Proper fan connector

Is there a 3 pin fan header on a desktop?

Fan has a 3-pin power connector; desktop board has a 4-pin fan header: Note: when using a 3-pin power connector with a 4-pin fan header, the fan will always be on; there is no fan control.
