Once you have removed the old thermal paste, it's time to apply the new paste. This model has a hole in the heatsink so it does not need thermal paste applied on the smaller pad.
-
Do not use too much thermal paste, just enough to cover the bigger portion of the pad. If you have a spreader, use it. The thermal paste will apply evenly after you tighten the heatsink.

Put the heatsink back carefully and tighten the screws in order 1, 3, 2, 4 to ensure even pressure. Don't forget to plug in the fan cable again.
