Cavo a Y per ventole Kolink 1-a-4 PWM 35 cm, 4-Pin PWM su 4×4-Pin PWM + SATA

Kolink 1-to-4 PWM 35 cm fan splitter cable provides a single 4-pin PWM input and four 4-pin PWM outputs with an integrated SATA power connector. The 35 cm cable is designed to let you connect and control up to four PWM fans from one motherboard PWM header while supplying extra current through SATA power for stable operation. PWM control lets the motherboard vary fan speed automatically according to temperature or BIOS/firmware settings, reducing noise when full airflow is not required.

Advantages

This splitter supports independent PWM signal distribution to four fans while offloading power draw to the SATA connector to avoid overloading the motherboard header. The 35 cm length balances reach and cable management inside most PC cases. Using a single PWM source ensures synchronized speed control without requiring separate fan headers or manual voltage modification. The SATA power feed allows multiple higher-current fans to run reliably without causing voltage drop or instability at the motherboard connector.

Suitable for

• Expanding a single motherboard PWM fan header to multiple chassis or radiator fans
• PC builds where synchronized PWM control across several fans is desired
• Systems where additional power is needed to run multiple fans without stressing the motherboard header
• Cooling configurations in mid-tower and full-tower cases with moderate cable routing distance

Key specifications

• Cable type: 1-to-4 PWM fan splitter
• Connectors: one 4-pin PWM input, four 4-pin PWM outputs, one SATA power connector
• Length: 35 cm (0.35 m)
• Control: PWM signal pass-through for synchronized speed control
• Power: SATA power feed for additional current to connected fans

How to use

Connect the single 4-pin PWM input to an available 4-pin fan header on the motherboard. Plug up to four 4-pin PWM fans into the splitter outputs. If more than one fan is connected or the combined current draw may exceed the motherboard header rating, connect the SATA power plug to a spare SATA power cable from the power supply to supply additional current. Configure fan control in the motherboard BIOS or operating system fan control software to use PWM control on the connected header.

Recommendations

Do not connect the SATA power plug while the system is powered on to avoid connector damage; connect it before powering the system. Verify that the combined fan current does not exceed the power supply rail capacity. For optimal airflow and noise characteristics, place fans in recommended intake/exhaust positions and use motherboard PWM profiles to manage speeds.
