Alphacool 18679 RGB splitter cable, black, plastic, 150mm

The Alphacool 18679 RGB splitter cable is a sleeved distribution cable that converts one 4-pin connector into three 4-pin fan/RGB connectors. Made with black plastic housings and protective sleeving, the 150mm cable transfers power and PWM/RGB signal to multiple fans or RGB devices while improving cable durability and routing stability.

Advantages

The sleeving offers extra protection against abrasion and helps keep individual wires bundled for cleaner cable management. The Y-splitter design enables one header to power and control up to three 4-pin connectors, reducing the need for additional controllers or headers. Compact 150mm length simplifies internal routing without excess slack.

Suitable for

• Connecting multiple 4-pin PWM fans to a single motherboard or fan hub header
• Distributing RGB/power signal to several 4-pin RGB devices
• Systems where limited fan headers require splitting to add additional fans

Key specifications

How to use

Connect the single 4-pin input plug to the motherboard fan header, RGB header, or fan hub output. Attach up to three 4-pin fans or RGB devices to the splitter outputs. Ensure connectors are aligned and fully seated before powering the system. Verify that the combined current draw does not exceed the source header or hub specifications.

Recommendations

Use the splitter for low- to moderate-current fans and RGB devices. If connecting multiple high-current fans, check the motherboard or hub current limits and consider using a dedicated fan controller or separate power sources to avoid overloading a single header.
