Product information

Description

The Sharkoon 3-pin to 4-pin adaptor is an essential internal PC cable accessory designed to bridge hardware connection gaps in your desktop computer build. This reliable adapter enables the connection of 3-pin cooling fans, such as CPU coolers or case fans, directly to a 4-pin power source or motherboard header. By providing seamless hardware compatibility, it ensures efficient system cooling management and stable power delivery for your components.

Advantages

This Sharkoon adaptor offers a straightforward solution for hardware compatibility issues within desktop computer systems. It allows users to utilize existing 3-pin cooling fans with newer or alternative 4-pin power sources without requiring hardware replacements. The reliable internal connection supports effective system cooling management and contributes to stable thermal performance during computer operation.

Suitable for

  • Connecting 3-pin case fans to a 4-pin power supply or motherboard header
  • Integrating 3-pin CPU cooling fans into systems with limited 3-pin ports
  • Desktop computer assembly, upgrades, and custom PC building
  • Improving hardware compatibility in existing computer systems

When it may not be suitable
This adaptor may not be suitable if you require PWM fan speed control, as standard 3-pin fans connected via a 4-pin power source typically operate at a constant maximum speed. It is also not designed for connecting high-power devices other than standard cooling fans.

Key specifications

  • Connector type one: 3-pin fan connection
  • Connector type two: 4-pin power or motherboard connection
  • Application: Internal PC cooling fan cable accessory
  • Compatibility: Standard 3-pin cooling fans and 4-pin power sources

How to use
To use the Sharkoon 3-pin to 4-pin adaptor, first power down and unplug your desktop computer. Locate an available 4-pin power source or motherboard header inside the chassis. Align the 3-pin connector from your cooling fan with the corresponding pins on the adaptor, ensuring a secure fit. Then, plug the 4-pin end of the adaptor into the designated power source or motherboard header. Double-check all connections before restoring power to the system.

What to consider before purchase

  • Verify the pin configuration of your existing cooling fans and target power headers
  • Determine whether constant fan speed is acceptable for your cooling setup
  • Check available cable routing space inside your computer case
Usage recommendations
Always ensure the computer is fully powered off and disconnected from the mains electricity before installing or removing any internal PC cables. Inspect the pins on both the fan and the adaptor to prevent bending during connection.
