Y-splitter cable 3-pin Alphacool 18692, 60 cm length

Alphacool 18692 is a 3-pin Y-splitter cable, 60 cm long, designed to split one standard 3-pin connection into two outputs. The cable preserves the standard 3-pin pinout so that power and tachometer signal are shared between the two connected devices. Its length and connector arrangement allow flexible routing inside computer cases and straightforward extension of fan arrays or other 3-pin peripherals without needing additional motherboard headers.

Advantages

The Y-splitter provides a simple and compact way to double the number of devices on a single 3-pin header while maintaining signal integrity for tachometer reporting. At 60 cm length it offers sufficient reach for typical case layouts and fan placements. The cable is compatible with standard 3-pin fans and low-power peripherals, enabling a neat installation without custom wiring or adapters.

Suitable for

• Connecting two 3-pin case fans to a single motherboard or controller header
• Expanding fan arrays in compact or mid-tower PC cases
• Powering additional low-power 3-pin peripherals such as small pumps or LED controllers (where supported)
• Temporary testing or troubleshooting of fans and 3-pin devices

Key specifications

• Cable type: 3-pin Y-splitter
• Connector configuration: one 3-pin male to two 3-pin female
• Length: 60 cm total cable length
• Signal support: shared +12V power and tachometer (RPM) signal
• Compatibility: standard 3-pin fans and peripherals with matching pinout

How to use

Connect the single male 3-pin plug to the motherboard header or fan controller output, then attach up to two compatible 3-pin devices to the female connectors. Ensure connectors are aligned with the keyed housing and fully seated. Do not force connectors; if resistance is felt, check orientation and compatibility. After installation, power on the system and verify both devices receive power and that the tachometer signal is reported correctly by the motherboard or controller.

Usage recommendations

Use this splitter only for low-current devices such as case fans or compatible peripherals. Verify the combined current draw of connected devices does not exceed the rated current of the motherboard header or controller output. For PWM (4-pin) speed control, use a dedicated PWM splitter or connect to separate PWM-capable headers. Route the cable to avoid interference with moving parts and secure it with cable ties if needed.
