If you want to tackle this crazy job and need some guidance, then here it is. Expect upwards of 2 hours to complete. I had 90 minutes worth of footage to edit meaning this job took me 90 minutes. If I were to do this again it would probably take me 60 minutes, at best.

After a year or so you'll likely find yourself here in need of this teardown. Best of luck! Thermal paste doesn't last forever! Usually 12 months depending on use and climate.
