Agree with the Kit. The following from an article, referring to laptop heat-sink. (in comments)
"For something like that, I would use the smooth spread method. Getting perfect coverage on a non-square shaped die is going to be difficult unless you do the spreading yourself. If you are unsure if the coverage is good or not, it's usually a good idea to apply the thermal paste, install the heatsink, then remove the heatsink and see how well it spread. Check that the entire die is covered and that not too much was pressed out the sides. You will want to clean off the die and heatsink and reapply the thermal paste, but at least you will know for sure if you are using the right amount."

You will need the above kit. two magnetic tipped Phillips head screwdriver, a #1 and a #2. Some cotton buds. a can of compressed air. Patience.
Please remember to remove the battery and take anti static measures by briefly touching a bare part of the computer chassis. When blowing air on a fan, place a finger or cotton bud on a vane to prevent it spinning.
another couple of guides.
These are very useful guides! Great. I'm still trying build up confidence in doing this so its not immediate action. But I will have to do this one way or another to correct my problem.
