Arctic Silver is your friend. There's two different ways to apply it, one is easy but doesn't guarantee a good spread, the other guarantees but is harder to do:
Either method stars with: Clean the surface using rubbing alcohol (70% alcohol, you can find it in the medical section of any neighborhood grocer like HEB or Walmart) and cotton balls. If you need to clean the area around the CPU (or GPU) Q-Tips work well. Make sure that the surface is nice and clean and dry. The alcohol will dry out in air in less than a minute, you can gently blow on it to speed this up. Once its clean, its time to apply paste
1. The easy way: in the very center of the chip, squeeze out a dot about the size of a grain of rice (about an 1/8 of an inch, or 4 mm) long. Carefully re-attach the heat block (whatever it is you are using).
2. The more difficult way: Squeeze out a very thin line of thermal paste along the left edge, about 1mm away from the side of the chip. Very carefully and very slowly use the edge of a credit card (or similar hard plastic card, I used my Walgreens Rewards card
) slide the card across the chip to spread it out. Keep spreading in the same direction until you have given yourself an even, very thin layer of paste. If you didn't squeeze out enough to cover all the way to the right side of the chip, squeeze an additional dot of paste (<1mm in diameter) to the upper right corner of the chip and start swiping the card from the top to bottom, this should cover the gap. Any excess paste should have come off the chip onto the card and can be cleaned off with alcohol and a cotton ball or two.
Things you need to watch for: If you apply your heat block all the way on (screwed in and everything) and then take it right back off, there shouldn't be any paste squeezed off the edge of the chip by the heat block. This is often the mistake of manufacturer paste applications, it can be pretty bad. Remember the best heat path is always direct block to chip, the paste is only there to fill in the microscopic crevices on both surfaces (which makes the overall process work better) but too MUCH paste actually gets in the way.
