Replacement fan cable for ThinkPad T440S and T450S

This internal power cable connects the CPU cooling fan in Lenovo ThinkPad T440S and T450S series laptops. It matches part numbers 04X0445 and 04X1850 for direct compatibility. The cable restores the link between the motherboard and the fan assembly. Install it when the original cable is damaged or missing.

Replaces a broken or lost OEM fan power lead

The jump is worth it when the existing cable prevents the fan from spinning or reporting speed. It does not upgrade performance or add features. Buyers who need a different connector pin-out or a longer harness for another model should look elsewhere.

Questions about this item

What connector does the internal power cable use to attach to the Lenovo ThinkPad T440S or T450S motherboard?

The cable plugs directly into the motherboard fan header used by the CPU cooling fan assemblies 04X0445 and 04X1850.

Which step do installers most often miss when fitting this cable inside the ThinkPad T440S or T450S?

They forget to route the cable under the metal bracket before locking the connector, so the fan sits flush and the latch engages.
