InLine Fan Adapter 3pin female / 2x 3pin male approx. 0.10m

InLine Fan Adapter 3pin female / 2x 3pin male approx. 10cm allows two 3-pin fans to be connected to a single 3-pin motherboard header. The adapter transmits the speed (tachometer) signal from the first connected fan to the motherboard while providing power to the second fan. With an approximate cable length of 10 cm and a compact multicolour cable, it helps organize fan connections inside PC cases where additional fan headers are needed.

Advantages

The adapter enables connection of two 3-pin fans to one motherboard socket without additional soldering or modification. It preserves the tachometer signal from the primary fan so the motherboard can monitor fan speed, and its short 10 cm length reduces cable clutter inside the case. The compact multicolour cable is compatible with standard 3-pin fan connectors and is ready for immediate installation.

Suitable for

• Connecting two 3-pin case fans to one 3-pin motherboard header
• PC builds with limited fan headers
• Temporary fan testing or troubleshooting

Key specifications

• Connectors: 1 × 3-pin female to 2 × 3-pin male
• Cable length: approx. 0.1 m (10 cm)
• Colour: Multicolour
• Brand: InLine
• MPN: 33433
• EAN: 4043718020096

How to use

Insert the 3-pin female connector into the motherboard's 3-pin fan header, then connect up to two 3-pin fan plugs to the male connectors. Ensure the keyed connector orientation matches the header to avoid incorrect pin alignment. The motherboard will read the RPM signal from the first fan connected; the second fan will receive power but its speed will not be separately reported.

Recommendations

The adapter is intended for standard 3-pin fans and is not a PWM splitter for 4-pin headers. For accurate speed monitoring of multiple fans, use a hub or controller that supports multiple tachometer inputs. Avoid drawing more current than the motherboard header's rated output; check your motherboard specifications for maximum fan current per header.
