Unscrew the 4 screws holding the CPU heatsink and disconnect the fan.
Lift up the assembly, gently.
Clean the old thermal paste both from the cooler and the CPU. It is best to use isopropyl alcohol and cotton swabs or paper towel, but be careful not to go too hard on the CPU.
Dont use too much thermal paste, just enough to cover some portion of the dye. If you have a spreader, use it. The thermal paste will apply evenly after you tighten the heatsink.
Replace the thermal pad on the video chip if necessary. Be sure to use the same thickness thermal pad.

Once you opened the back cover, it is a good idea to upgrade the SSD and RAM if you want.
When you remove the heatsink assembly you can also upgrade the CPU. You can do this by twisting the screw on the socket and carefully lift up the CPU.
