InLine ventilator-adapterkabel, 3-pins ventilator / 4-pins voeding, 0,3 m

The InLine Fan Adapter Cable 3pin Fan 4pin power supply 33344A is an adapter cable for connecting chassis fans with a 3-pin mainboard interface directly to a PC power supply via Molex connectors. With a length of 0.3 m and two 4-pin Molex plugs, it lets you power a 3-pin fan where a motherboard header is unavailable or when you prefer to draw power directly from the PSU.

Advantages

This adapter provides a simple and reliable way to power 3-pin chassis fans from a standard 4-pin Molex power connector. Its short 0.3 m cable helps keep internal wiring tidy and reduces cable clutter. The cable is compatible with a wide range of PC systems and fan models that use a 3-pin connector.

Suitable for

• Powering 3-pin chassis fans when motherboard headers are full or absent
• Replacing or extending fan power connections inside desktop PCs
• Testing or temporarily powering a fan from the PSU

Key specifications

• Cable length: 0.3 m
• Connector 1: 3-pin fan connector
• Connector 2: 2 × Molex (4-pin)
• Brand: InLine
• MPN: 33344A
• EAN: 4043718147724

How to use

Connect the 3-pin fan plug to the fan's header, then attach one of the Molex 4-pin plugs to an available Molex connector from the power supply. Ensure connectors are aligned and fully seated. If the PSU provides multiple Molex outputs, use the nearest one to minimize cable tension. Do not force connectors; they should slide in smoothly when correctly oriented.

Recommendations

Use this adapter only for standard 3-pin DC fans. Avoid using it with fans that require PWM control via a 4-pin motherboard header if speed regulation is needed — this adapter supplies constant power from the PSU and does not provide PWM control.
