Two black-sleeved Molex-to-fan adapter cables, 10 inch length

Vszerda

Vszerda 2 Pack Molex to 3/4 Pin Fan Power Adapter Cable 10 inch

SKU CH-VXE3-CJ37T

Two adapters connect 3-pin or 4-pin PWM fans to Molex power at fixed 12V using 10-inch sleeved cables

  • Connect 3-pin or 4-pin PWM fans to Molex power
  • Fans run at fixed 12V from Molex supply
  • Two adapters included for dual-fan setups
  • High-density black sleeving protects 10-inch cables
  • 4-pin Molex plug uses only two active pins

Vszerda Molex to 3/4 Pin Fan Adapter

This two-pack of Vszerda adapter cables connects three-pin or four-pin PWM case fans directly to a four-pin Molex power connector. The Molex end is wired with only two active pins, yet it supplies the full 12 V rail to the fan. Builders who need a quick way to power extra fans from a spare Molex lead will find these cables fit the task.

Fixed 12 V Operation and Thermal Behaviour

Because the adapters draw from the Molex 12 V line, connected fans run at a constant 12 V with no speed control or PWM signalling. The high-density black sleeving protects the wires and adds minimal resistance, so power delivery stays steady and the cables themselves generate negligible heat. Noise levels depend entirely on the fan model chosen, since the adapter does not regulate voltage.

10 Inch Sleeved Cables for Internal Routing

Each cable measures 10 inches and is wrapped in high-density black sleeving that resists abrasion inside a crowded chassis. The short length suits tight routing between a power supply's Molex connectors and nearby fan headers, but it may not reach distant mounting points in larger cases. The pack includes two identical adapters, so a second fan requires a separate Molex connector. Builders who need variable fan speed or longer cable runs should look elsewhere.

Highlights

  • Connect 3-pin or 4-pin PWM fans to Molex power
  • Fans run at fixed 12V from Molex supply
  • Two adapters included for dual-fan setups
  • High-density black sleeving protects 10-inch cables
  • 4-pin Molex plug uses only two active pins

Questions about this item

How do I plug the 2-pin Molex end into my power supply without bending the pins?

Align the two live pins with the yellow and black sockets on the Molex connector, press straight in until the latch clicks, and route the 10 inch sleeved cable away from sharp edges.

Will the fan header or the Molex pins wear out first if I swap fans regularly?

The fan header is rated for more insertion cycles than the Molex pins, so the Molex side will show looseness first with frequent changes.

At what point does the fixed 12 V supply become a limitation for PWM fan control?

Because the adapter delivers a constant 12 V, the fan runs at full speed regardless of the PWM signal, so speed control is lost immediately.
