Predlžovací kábel ventilátora Akasa AK-CBFA01-KT04, balenie 4 ks, PWM, 4-pinový konektor, predlžovacie vodiče

Akasa AK-CBFA01-KT04 is a set of four PWM fan extension cables with standard 4-pin connectors designed to increase the routing flexibility of PC cooling systems. Each cable preserves the PWM (pulse-width modulation) signal so fan speed control remains available from the motherboard or fan controller. The cables are intended for desktop computer builds where stock fan leads are too short to reach headers or when cleaner cable management is required.

Advantages

These 4-pin PWM extension leads maintain the full four-wire connection including power, ground, tachometer (RPM) and PWM control, ensuring automatic and manual fan speed adjustments continue to function. Supplied as a four-pack, the set allows multiple fans to be extended simultaneously. The connectors match common motherboard fan headers and typical 120 mm/140 mm fan cables, which simplifies installation without modifying original fan wiring.

Suitable for

• Extending PC case fan cables to reach distant motherboard headers
• Neatening cable routing for improved airflow and aesthetics
• Connecting fans to fan controllers or hubs located away from the fan
• Replacing short or damaged fan leads without splicing

Key specifications

• Connector type: standard 4-pin PWM female-to-male connectors
• Wiring: four-conductor cable preserving power, ground, tachometer and PWM signal
• Pack quantity: four extension cables
• Compatibility: designed for 4-pin PWM-controlled PC fans and motherboard headers
• Use case: internal PC fan power and control extension

How to use

Connect the male end of the extension cable to the fan’s 4-pin connector and plug the female end into the motherboard fan header or a fan controller. Ensure the connector orientation matches the header’s pin layout to maintain correct power and PWM signal alignment. After installation, verify that the system recognizes the fan and that speed control works as expected in BIOS or monitoring software.

Recommendations

Use these extension cables only inside the PC chassis and avoid routing them near moving parts or sharp edges. For best results, plan cable paths before installing components, and secure extensions with ties or clips to prevent strain on connectors. If multiple fans are connected to a single header via a hub, check the motherboard header’s power limits to avoid overloading.
