Broken doesn't stand a chance.
Maneuver the palm rest away from the keyboard carefully, both the keyboard and palm rest/trackpad will come off together. **WARNING** Both the keyboard and trackpad have connectors to the motherboard. Disconnect these before completely removing either component.

Unscrew the three shown screws (red), then unplug its connection with the motherboard (blue). **Since both the processor and graphics processor unit are attached to this fan with thermal paste, removing the fan might require some force and a flathead screwdriver to separate the paste from the fan.

How about you just down the freely available Hardware Maintenance Manual (HMM) for the laptop. They are downloadable in PDF format, and very well done.
