## Summary description

The Alphacool 18690 internal power cable is 0.6 m long, featuring a 3-pin connector and two 3-pin fan connectors. It is CE and RoHS compliant, ensuring safety and environmental standards. This cable is designed to connect fans to your power supply efficiently, making it ideal for PC builders and enthusiasts.

## Long description

The Alphacool 18690 internal power cable is a 0.6 m sleeved 3-pin to 2x 3-pin Y-splitter designed to distribute power and RPM signal from a single 3-pin header to two fans. Constructed with protective sleeving, the cable provides improved mechanical stability and longer service life while remaining compliant with CE and RoHS standards.
Advantages
The sleeved design offers additional protection against abrasion and cable movement, while the Y-splitter topology enables powering and RPM monitoring of two fans from one 3-pin connector. Its 0.6 m length provides flexible routing inside PC cases without excessive slack, and CE/RoHS compliance ensures adherence to safety and environmental requirements.
Suitable for
Connecting two 3-pin case fans to a single 3-pin motherboard or controller header
Expanding fan connections in compact builds with limited headers
Systems where RPM signal monitoring for multiple fans is required
Key specifications
Manufacturer: Alphacool
Model / MPN: 18690
Length: 0.6 m
Connector: 1 x 3-pin (male) to 2 x 3-pin (female) Y-splitter
Function: Power distribution and RPM signal splitting for fans
Compliance: CE, RoHS
EAN: 4250197186902
How to use
Plug the single 3-pin end into the motherboard, fan controller, or power source 3-pin header. Connect up to two 3-pin fans to the dual 3-pin outputs. Ensure connectors are fully seated and route the sleeved cable to avoid sharp bends or contact with moving parts. Note that a 3-pin connection supplies voltage and RPM signal but does not provide PWM control.
Usage recommendations
For reliable operation, avoid overloading the source header; check the header or controller maximum current rating and the combined current draw of connected fans. Use this cable in systems where voltage-based speed control is acceptable and consider a powered fan hub or 4-pin PWM splitter when independent PWM control or higher power capacity is required.
