HP L94041-001 thermal module is a replacement cooling component listed for HP Envy 13 Laptop PC models with discrete memory. It is the discrete-graphics variant of the heat sink assembly, intended for the corresponding system configuration.
HP’s service guide distinguishes it from the UMA thermal module, part number L94042-001. This matters because the two parts are assigned to different memory and graphics configurations in the parts catalogue.
The service procedure describes L94041-001 as the discrete heat sink and specifies that the fan is removed before the heat sink. The heat sink is attached to the system board with six Phillips M2.0 × 3.0 screws.
