Delock cable divisor de ventilador 1 x conector hembra PWM de 4 pines a 2 x conector macho PWM de 4 pines (el segundo con 3 pines ocupados) funda trenzada 30 cm negro

This Delock fan splitter cable stands out by offering a true dual-fan PWM solution from a single motherboard header, with the second output deliberately wired for 3 pins to prevent conflicting RPM signals. The braided nylon sleeve not only looks clean but also protects the conductors from abrasion in tight builds. At 30 cm, it reaches most fan positions without excess slack.

Highlights

• Splits one 4-pin PWM fan header into two fan outputs
• First output: full 4-pin PWM with RPM feedback
• Second output: 3-pin wired (PWM control, power, ground) – no RPM feedback to avoid signal conflicts
• Braided nylon sleeving for durability and tidy cable management
• 30 cm length ideal for standard ATX cases
• Black colour blends seamlessly with most builds

In daily use

Connect the female 4-pin PWM connector to your motherboard CPU or chassis fan header, then attach up to two PWM fans. Both fans receive the same PWM speed control signal, so they ramp up and down together. The first fan reports its RPM to the motherboard for monitoring, while the second fan runs without tachometer feedback – a common and reliable configuration for push-pull radiator setups or front intake pairs.

Final note

Deliver clean, synchronised fan control without the clutter of multiple cables or the risk of RPM signal conflicts – a practical upgrade for any air-cooled build.
