IDE Molex 4Pin D Plug to 3Pin Fan Power Cable, PC Cooling Fan Power Converter Cable for Computer Chassis Cooler

This Molex IDE 4Pin D to 3Pin fan power converter cable is a practical accessory for desktop computer cooling systems. It enables you to power 3Pin cooling fans straight from the power supplys Molex IDE D-type connector when your motherboard runs out of built-in fan headers.

Supplying power directly from the PSU effectively prevents overloading the motherboard fan circuits and reduces potential risks such as circuit burnout. It outputs constant 12V power and fits most common 3Pin DC cooling fans, including case intake & exhaust fans, water cooling radiator fans and auxiliary cooling fans.

Constructed with high-purity copper conductors to minimize voltage drop during power transmission. Injection molded connectors offer tight and reliable connection, which will not loosen easily under chassis vibration. The durable outer cable sheath resists abrasion and repeated bending for long-term continuous use. Plug and play, no driver or extra configuration required.

Important Note: This cable only delivers power to cooling fans. It cannot transfer fan speed signals, so fan speed monitoring and PWM speed control functions are unavailable. Please check the power consumption of your fan to make sure it does not exceed the rated load of the Molex connector before installation.
