Lenovo Thermal Module

Lenovo 5H40X63204 is a CPU cooling assembly that combines a heatsink and fan. It is intended to dissipate heat from the processor and move air through the cooling assembly, making it a replacement part for supported Lenovo laptops.

The listed compatibility includes the ThinkPad T490s, types 20NX and 20NY, as well as ThinkPad T490 types 20N2/20N3, 20Q9/20QH and 20RY/20RX. The exact part number identifies the assembly as the Citizen heatsink-with-fan variant. IPC describes it as an original Lenovo part.

This is a notebook cooling component, not a standalone fan: the listing identifies both the heatsink and fan as part of the same assembly. Its stated purpose and supported systems make it suitable for servicing the cooling system in the listed ThinkPad models.
