PWM Fan Y-Cable THERMALTAKE Tt Mod AC-060-CO1OTN-F1 4-pin, 3-pack

PWM Fan Y-Cable THERMALTAKE Tt Mod AC-060-CO1OTN-F1 4-pin, 3-pack is a 4-pin PWM splitter designed to expand a single motherboard or controller fan header into two connections while maintaining PWM speed control. Supplied as a set of three identical Y-cables, each cable routes power, ground, tachometer and PWM signal lines so two fans can be controlled from one header. The compact design and standard 4-pin connectors make it compatible with most PC fans and modern motherboards, helping to simplify wiring and support additional cooling without the need for extra fan headers.

Advantages

This 3-pack of PWM Y-cables preserves the PWM speed control signal and tachometer feedback, ensuring both connected fans respond to motherboard or controller commands. The splitter supports standard 4-pin fan pinouts and reduces the need to reroute power or use additional adapters. By combining two fan connectors into a single header, it offers a tidy cable layout and a practical solution for builds with limited fan headers.

Suitable for

• Expanding a single 4-pin motherboard or controller header to power two PWM fans
• PC builds with limited fan headers
• Cooling upgrades where additional fans are required without modifying the power supply
• Improving cable management inside desktop computer cases

Key specifications

• Connector type: 4-pin PWM female to dual 4-pin PWM male splitter
• Signal support: PWM speed control and tachometer (RPM) feedback
• Quantity: pack of three identical Y-cables
• Compatibility: standard 4-pin PC fans and motherboard fan headers
• Cable layout: single input to dual output configuration

How to use

Connect the single 4-pin end of the Y-cable to the motherboard or fan controller header, ensuring correct pin alignment for power, ground, tachometer and PWM signal. Attach up to two 4-pin PWM fans to the dual outputs. Verify that the motherboard or controller recognizes the connected fans and reads RPM values. If using multiple Y-cables, distribute them to headers with adequate current capacity and ensure the combined fan power draw does not exceed the header or controller specifications.

Recommendations

Use these Y-cables to add additional PWM fans where header availability is limited, but check motherboard or controller documentation for maximum supported current per header. For optimal system cooling and reliable fan control, connect fans with similar power and speed characteristics when sharing a single header.
