Sounds good.As far as the thermal paste goes yes clean the item that you are using the thermal paste on. Wiping the surface lightly with a cotton ball or cotton swab dampened with Isopropyl Alcohol. The higher the percentage of alcohol the better. 70 percent is good but 90 percent is better if it can be found.Looking around the internet, you’ll find a lot of different philosophies about how to apply thermal paste. Some people say you should apply it in a dot size, some a pea, some a line, some two lines, some an “X,” and so on. Truth is, all you’re trying to do when applying thermal paste is to get a paper-thin layer of the stuff over as much of your CPU as possible.
