Understanding the 4 Pin Fan and Molex Connector
What is a 4 Pin Fan Connector?
The 4 pin fan connector is the standard connection for most PC case fans. It provides power to the fan motor and allows for pulse width modulation (PWM) control, which enables the motherboard to adjust the fan speed based on temperature. The four pins carry different signals: ground, +12V, sense (tachometer), and PWM control.
What is a Molex Connector?
A Molex connector is a larger, 4-pin power connector commonly used for older devices like hard drives and optical drives. While less common for modern fans, it can still be utilized with the appropriate adapter. These connectors provide a straightforward +12V and ground connection, meaning fans connected this way will typically run at full speed.
Methods for Connecting a 4 Pin Fan to Molex
Using a Molex to 4 Pin Fan Adapter
The easiest and safest method is to use a molex to 4 pin fan adapter. These readily available adapters convert the molex connector’s power into the format required by the 4 pin fan connector. Simply plug the molex connector into the power supply and the 4 pin fan into the adapter.
Direct Wiring (Not Recommended)
Directly wiring a 4 pin fan to a molex connector is highly discouraged unless you have significant electrical experience. Incorrect wiring can damage your fan, power supply, or even the entire system. If you must proceed this way, ensure precise connection of the ground and +12V wires and leave the sense and PWM wires unconnected.

Troubleshooting and FAQs
Why is My Fan Not Spinning?
Check the connections to ensure both the molex and 4 pin connectors are securely seated. Also, verify the power supply is functioning correctly. You might also consider a cáp chia cpu fan if you’re connecting multiple fans.
Can I Control the Fan Speed with a Molex Connection?
Generally, no. Molex connections provide constant power, resulting in the fan running at full speed. For speed control, consider a connection to the motherboard’s 4 pin fan header.
