Product information

Description

The InLine Fan Adapter Cable 0.3 m 3-pin to 2 x Molex 4-pin Power Supply is an essential internal PC component designed to connect computer case fans directly to the power supply unit. With a convenient length of 0.3 meters, this cable bridges the connection between standard 3-pin fans and 4-pin Molex power connectors, allowing for straightforward hardware integration inside your computer chassis. Its multicolour design further assists with neat cable management, helping you easily identify and route wires during your PC build or upgrade process.

Advantages

This adapter cable provides a reliable solution for powering chassis fans when standard motherboard fan headers are fully occupied or unavailable. By connecting the fan directly to the power supply unit via Molex connectors, you ensure a steady power delivery to your cooling system. The looped-through power supply connector ensures that the power connection remains available and unassigned for other internal devices. Additionally, the optimal 0.3-meter length offers enough reach for most standard computer cases without creating excessive cable clutter.

Suitable for

  • Connecting computer case fans directly to the power supply unit
  • Expanding cooling options when motherboard fan headers are limited
  • PC assembly and custom desktop upgrades requiring alternative fan power sources

When it may not be suitable

This adapter cable is not suitable if you require fan speed monitoring, as the fan speed signal is not transmitted through this connection. It is also not appropriate for components that require variable voltage control via motherboard PWM headers, as it supplies a fixed power output.

Key specifications

  • Cable length: 0.3 m
  • Connector 1: 3-pin
  • Connector 2: 2 x Molex (4-pin)
  • Colour: Multicolour

How to use

To use the InLine Fan Adapter Cable, first ensure your computer is powered off and disconnected from the electrical mains. Connect the 3-pin end of the adapter cable to your computer case fan. Next, attach the 4-pin Molex connector to an available Molex power cable coming from your power supply unit. Ensure all connections are secure and properly aligned before powering the system back on. Take care with cable routing to maintain proper internal airflow within your PC chassis.

What to consider before purchase

  • Verify that your computer case fan features a compatible 3-pin connector
  • Check if your power supply unit has an available 4-pin Molex connector
  • Note that fan speed signals will not be transmitted to the motherboard through this adapter

For optimal system performance and safety, always ensure the computer is unplugged before installing internal cables, and arrange the multicolour wires securely to maintain unobstructed airflow inside the PC case.
