Cable adapter NZXT 2-pin to 3-pin, red, model 99000037

The NZXT 2-pin to 3-pin cable adapter in red is a compact conversion cable designed to adapt a 2-pin connector to a 3-pin connector. It provides a simple physical interface to allow compatibility between headers and devices that require a 3-pin input when only a 2-pin source is available. The adapter is intended for use with fans, RGB controllers and other peripherals in system builds, repairs and component testing.

Advantages

This adapter offers a space-saving solution for connecting devices without replacing existing cabling or headers. Its red color aids visual identification in crowded cases and helps maintain consistent cable management. The cable is lightweight and easy to route, allowing quick temporary or permanent connections during assembly and troubleshooting. It enables cross-compatibility between mismatched connectors without altering device wiring.

Suitable for

• Connecting fans that require a 3-pin input when only a 2-pin header is present
• Linking RGB controllers or lighting modules to alternative power or signal sources
• Temporary connections during component testing and diagnostics
• Quick repairs or modifications in system builds where replacing headers is impractical

Key specifications

• Connector conversion: 2-pin to 3-pin
• Cable color: red
• Designed for low-voltage DC peripheral connections (fans, RGB modules)
• Compact form factor suitable for tight case spaces
• Flexible insulated wiring for easy routing

How to use

Align the 2-pin end of the adapter with the available 2-pin header and gently insert until it seats firmly, ensuring correct polarity where applicable. Connect the 3-pin end to the device requiring a 3-pin input. Verify that the device receives power or signal as expected before completing your build. If the device does not operate, remove the adapter and recheck the connector orientation and seating.

Usage recommendations

Use the adapter only for compatible low-voltage peripheral connections and avoid forcing connectors into incompatible headers. For permanent installations or where signal integrity is critical, consider replacing the cable or header with a native 3-pin solution. Keep the adapter away from moving fans and sharp edges to prevent damage to the insulation.
