This is just a partial disassembly in order to clean and repaste the GPU, so we wont be taking apart the entire back plate in this guide.

Once disassembled, you can use air and a soft paintbrush to clean up any dust in the fan or heatsinks.

If repasting, use 99% Isopropyl Alcohol and cotton swabs (qtips) to remove all of the old thermal paste from the GPU and copper plate on the back of the heatsink.

All done! Follow the steps in reverse order to reassemble.
