FAQ:
Q: What is the name for the 4 pin fan connectors?
A: A four pin connector is a little different than the three pin connector since it has the extra (fourth) wire used for controlling and sending signals to the fan, which likely has a chip on it that tells it to slow down or speed up (in addition to the other wires the three pin connector has). Three Wire and Four Wire Fan Connectors
Q: Is there way to control 3 pin fans?
A: If your motherboard only has 3-pin connections, though, you can sometimes control the fans by changing the voltage supplied to the fan. Not all motherboards support this, so you’ll probably have to check your motherboard’s manual or search the web for answers.
Q: What is a 4 pin fan?
A: A 4-pin fan is designed for control a different way, by giving it a fixed voltage supply and then a special signal called PWM on Pin #4. The 4-pin fan has its own internal circuit to apply that PWM signal to its power supply to adjust its speed. This means of control is called “PWM Mode”.
Q: What is a fan connector?
A: “Chassis Fan Connector” is a pin power connector that goes from your motherboard to the case’s fan, or from “Fan Controller” (Also called “Reobass”) hardware to the fan. There are two types of pin connectors: 3-pin and 4-pin.
