What is the 3 pin fan connector called?

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).

What are the 3 pins on a computer fan?

The Answer 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’s speed. With this type, fan speed is typically controlled by increasing or decreasing the voltage over the power wire.

Can I connect a 3 pin fan to a 4 pin connector?

1 Answer. Apparently a 3-pin fan can plug directly into a 4-pin socket. Two of the pins provide power to the fan, the 3rd provides an RPM pulse to the motherboard to read the speed. The 4th pin is for PWM speed control.

Where do 3 pin fan connectors go?

3-pin fans will plug directly into a 4-pin motherboard header without any additional adapters. 3-pin fans still have an RPM sensor on them, and most mainboards can still vary their speed based on temperature. 3-pin fans use simple voltage control for adjust the fan speed.

Do I need 3 or 4 pin fans?

The significant difference in practice is that 4-pin fans allow for RPM to change based on the need for cooling temperature, this reduces noise and power consumption. While 3-pin can control the voltage, but the voltage can’t turn to change the fan RPM at all and accurate as much as 4 pin fans.

Should I buy 3 or 4 pin fans?

Both will work as long as your motherboard has 4-pin headers for all the fans. 4-pin tends to be a bit more expensive and allows for greater control of fan speed. always used for CPU fans. 3-pin is generally used for case fans, but you COULD use a 4-pin if you happen to have one lying around.

Can you control 3 pin fans?

The speed of BOTH 3-pin and 4-pin fans can be controlled, but the method is different for the two types. For 3-pin fans, the connections to it are Ground to Pin #1, +VDC (varying) to Pin #2, and Speed signal on Pin #3.

Can I connect a 3 wire fan to a 2 wire connector?

The 3 Pin fan will fit onto the 2 pin you just need to match the holes and the pins and see which two contacts make the fan function.

How do you change a 3 pin fan to 2 pin?
