Cooling Fan for T440S and T450S

This replacement CPU cooling fan is built for Lenovo ThinkPad T440S and T450S laptops. It matches part numbers UDQFWYR02BCM, 04X0445 and 04X1850 and runs on DC5V at 0.5A. The unit is sold new with a 365‑day warranty.

Verify Model Before Ordering

This fan does not fit the standard T440 or T450 models; it is only for the T440S and T450S variants. Check the service tag or motherboard sticker to confirm the exact model and one of the three listed part numbers. The package contains a single fan without mounting screws or thermal paste.

Fits Directly Into the Existing Heatsink Assembly

The fan slots into the original heatsink housing using the stock connector and screw points. No adapter cables or BIOS updates are required. Replacing a worn unit restores proper airflow and frees the system from thermal throttling during sustained workloads.

Questions about this item

Does the box include only the fan or are mounting screws and thermal paste also supplied?

The package contains one CPU cooling fan; screws and thermal compound are not included and must be sourced separately.

How do I confirm this unit matches the UDQFWYR02BCM 04X0445 04X1850 part numbers for my T440s or T450s?

The fan is built to replace those three Lenovo part numbers and fits only the T440s and T450s models, not the base T440 or T450.

What does the DC5V 0.5A rating mean for everyday cooling performance?

It draws 0.5 A at 5 V, delivering the factory-specified airflow for the T440s and T450s thermal design.
