Molex to Quad Fan Adapter

This adapter cable connects a single 4-pin Molex power connector to four 3-pin or 4-pin PWM case fans. It solves the problem of insufficient motherboard fan headers or limited current capacity. The fans receive a fixed 12V supply from the Molex source, so speed control via PWM or voltage regulation is not possible. It is built for builders who need to run multiple fans from one power lead.

Installing the Splitter Cable

Installation is straightforward: plug the large 4-pin Molex end into a power supply lead and attach up to four fan connectors to the opposite ends. The black sleeved wiring uses 1007 24AWG tinned copper conductors with PVC insulation and an outer diameter of 1.4mm. The total cable length excluding connectors is 30cm, which may limit routing options in larger cases. No motherboard signal wire is present, so fan speed reporting and automatic control are unavailable.

Fixed Voltage Operation Limits

Because the adapter draws only the two power pins from the Molex connector, every attached fan runs continuously at the full 12V line voltage. This means 3-pin and 4-pin fans alike will spin at maximum speed with no thermal throttling or software adjustment. The assembly weighs 17 grams and is rated for 80°C operating temperature. It is not suited for builds that require variable fan curves or motherboard monitoring.

Questions about this item

How can I confirm the adapter is powering all four fans correctly after connecting it?

The fans should spin at full speed because the Molex connector supplies a fixed 12V; check each fan visually or in BIOS to verify they are running.

What connectors and cables are included, and is anything else required?

The cable has one large 4-pin Molex plug on the power-supply end and four 4-pin fan headers on the other; no extra parts are needed.

Which version should I choose if my motherboard has both 3-pin and 4-pin fan headers?

This single adapter works with both 3-pin and 4-pin fans because each header accepts either connector type.
