05:40 "now just put back the cover of the heatsink". This is by far the most difficult part of the process and it wasn't shown. At this point it is really easy to damage the CPU socket pins. Seriously stop and have a good think about how you are going to reassemble the the heat sink. To anyone attempting this, the CPU is held in place by a high tensile backplate and bracket. This attaches to the heatsink and radiator on the upper side of the CPU. Easy to take a part but an absolute pain in the ass to put back together. Add to this that you'll have thermal paste on the CPU and the GPU and it also becomes messy too. Consider using two people, helping hands or small amounts of hot glue or tape to hold parts in place while you work.
