Phobya 3-Pin Fan 12V to 7V Voltage Reducer 20cm Black Cable Extension 81068

Voltage reducer for 12V fans

This 20 cm cable lowers the supply from 12 V to 7 V for a standard 3-pin fan. The reduced voltage slows the fan for quieter operation and lower power draw. It suits builders who want a simple way to calm noisy cooling without fan controllers. The black sleeve keeps the wiring tidy inside the case.

Check connector and voltage needs

Verify that the fan you intend to run uses a 3-pin header and is rated for 12 V operation. The reducer plugs between the motherboard or controller header and the fan lead. Ensure the 7.9 in length reaches your routing path without strain. Fans requiring full 12 V for start-up torque may not spin reliably at the reduced level.

Fixed 7V output and short reach

The cable provides a single, non-adjustable 7 V step-down with no software or hardware control. It adds no monitoring, PWM conversion or additional headers. The 20 cm extension simply bridges the gap between header and fan while dropping voltage. Builders needing variable speed or longer runs must look elsewhere.
