InLine Fan Adapter Y-Cable 3pin Molex female / 2x 3pin Molex male 100 pcs.

The InLine Fan Adapter Y-Cable (3pin Molex female to 2× 3pin Molex male) allows two 3-pin fans to be connected to a single motherboard fan socket. The adapter passes the speed (tach) signal from the first fan to the motherboard while supplying power to the second fan, enabling simultaneous operation from one header. The cable length is 0.1 m and the product is supplied in bulk packs of 100 pieces.

Advantages

This compact Y-cable enables powering two fans from a single 3-pin motherboard header while preserving the rota­tion/speed signal of the primary fan. Its short 0.1 m length suits confined PC interiors and installation close to the header. Supplied in packs of 100, it is suitable for bulk installations and manufacturing use. The cable uses standard 3-pin Molex connectors for compatibility with common PC fans.

Suitable for (tasks / use cases)

• Connecting two 3-pin fans to one motherboard fan header
• Compact PC builds and small form-factor systems
• Bulk installations in assembly or repair workshops
• Replacing or extending existing fan connections

How to use

Attach the female 3-pin Molex connector of the Y-cable to the motherboard fan header. Plug the first fan into one of the male 3-pin connectors and the second fan into the remaining male connector. The motherboard will receive the tachometer (speed) signal from the first fan; both fans will receive power. Ensure connectors are fully seated and routed to avoid contact with moving parts.

Recommendations

Use this adapter when you need to power two 3-pin fans from a single motherboard header and monitor the speed of the primary fan. Do not rely on this cable to provide PWM speed control; it only transmits the tachometer signal from the first fan and supplies power to the second.
