Kábel Akasa PWM splitter 4-pin 2-násobný AK-CB002-KT02 pre napájanie ventilátorov a PWM signál

Akasa AK-CB002-KT02 is a 4-pin PWM splitter cable that divides one PWM fan header into two outputs, allowing two fans to receive both power and PWM speed control from a single motherboard or controller header. The cable preserves the PWM control signal and the 12V power line, enabling synchronized speed regulation of connected 4-pin fans while reducing the need for additional headers or external hubs.

Advantages

This 4-pin 2-way splitter supports simultaneous delivery of power and PWM signal to two fans without altering the original control line, maintaining fan speed synchronization when used with compatible 4-pin PWM headers. The compact and flexible cable design simplifies routing inside PC cases and reduces clutter compared to larger fan hubs. Passive operation requires no external power source or software, and compatibility with standard 4-pin PWM fans makes it a straightforward solution for expanding fan connections.

Suitable for

• Connecting two 4-pin PWM case fans to one motherboard fan header
• Expanding CPU cooler fan connections when a single header is available
• Small form-factor builds where additional fan headers are limited
• Systems that require synchronized fan speed control from one PWM source

Key specifications

• Connector type: 4-pin PWM female to dual 4-pin PWM male outputs
• Function: power and PWM signal splitting for 4-pin fans
• Design: passive splitter cable, no active electronics
• Cable length and flexibility: compact length suitable for internal PC routing
• Compatibility: standard 4-pin PWM fans and motherboard/controller PWM headers

How to use

Attach the single 4-pin end of the splitter to an available 4-pin PWM fan header on the motherboard or fan controller. Connect up to two 4-pin fans to the dual outputs, ensuring pin alignment (12V, ground, tachometer, PWM) matches the header orientation. After connection, verify that the BIOS or fan control software recognizes the fans and adjust fan curves or profiles as needed to achieve the desired cooling and noise balance.

Recommendations

Do not exceed the current rating of the motherboard header when connecting multiple fans; check the header’s maximum current specification in the motherboard manual. For high-power fans or when connecting multiple high-current devices, consider using a powered fan hub. Ensure secure and correct pin alignment when connecting to avoid damage to fans or the header.
