InLine Multi Port Panel 2x Molex 4 Pin to 12 x 3 Pin Fan connector for 12 fans

The InLine 33008 Multi Port Panel is a compact fan controller that lets you connect up to 12 fans to a single power source using two 4-pin Molex connectors. It provides grouped voltage outputs so fans can be powered at different voltage levels: four 12V ports, four 7V ports and four 5V ports. The module connects directly to the power supply and has a red LED to indicate power readiness. The unit’s multicolour finish and small footprint (45 × 105 × 20 mm) make it suitable for various computer cooling setups.

Advantages

The Multi Port Panel supports a high fan count without requiring multiple separate adapters, simplifies cabling by using two 4-pin Molex inputs, and offers three distinct voltage outputs for basic fan speed differentiation. Direct power-supply connection and a built-in red LED provide immediate status feedback. Its compact dimensions allow installation in confined spaces inside a PC chassis.

How to use

Connect the panel to your computer power supply using the two 4-pin Molex connectors. Plug fans into the 3-pin output ports according to the desired voltage groupings: the four 12V ports for full-speed operation, the four 7V ports for reduced speed, and the four 5V ports for lower speed. Ensure all connections are secure and route cables to avoid obstructing airflow. Power on the system and confirm the red LED is lit to verify the panel is receiving power.

Recommendations

Use the 12V ports for fans where maximum cooling is required, 7V ports for general-purpose cooling, and 5V ports when quieter operation is preferred. Do not exceed the current ratings of your power supply and distribute high-draw fans across both Molex inputs if necessary.
