Sharkoon 3-pin-naar-4-pin-adapter Sharkoon

This adapter allows connecting a CPU or case fan with a 3-pin connector to a free 4-pin 5.25" header. The Sharkoon 3-pin to 4-pin adaptor ensures compatibility between 3-pin fans and 4-pin motherboard or controller connectors so standard fans can be used in systems with 4-pin headers.

Advantages

The adaptor provides a simple mechanical and electrical connection without altering the fan wiring, preserving fan function. It is compact and easy to install, enabling use of existing 3-pin fans on 4-pin headers without the need for additional cables or modifications.

Suitable for

• Connecting 3-pin CPU fans to 4-pin motherboard headers
• Connecting 3-pin case fans to 4-pin fan controllers or hubs
• Upgrading or replacing fans in PC builds that use 4-pin connectors

Key specifications

• Connector type: 3-pin (fan) to 4-pin (5.25" header)
• Compatibility: 3-pin fans and 4-pin motherboard/controller headers
• Brand: Sharkoon
• MPN/EAN: 4044951001293

How to use

Turn off the system power before installation. Insert the fan's 3-pin plug into the adaptor's 3-pin side and then plug the adaptor into the available 4-pin 5.25" header on the motherboard or controller. Ensure the pins align correctly and the connection is secure before powering the system.

Recommendations

Do not force connectors; check pin alignment to avoid bent pins. If the motherboard or controller supports PWM on the 4-pin header, a 3-pin fan will run at voltage-controlled speeds rather than PWM-regulated speeds.
