A company in Japan has come out with this product called the Setten No.1 that can actually improve overclocking capability of your processor. This product is a surface treatment liquid for metal contacts eg. RAMs pins, CPU surface etc. It will smoothen the uneven metal surface that can't be seen in our naked eyes. Under a microscope you will see how uneven is your CPU surface. It can improve the electric and mechanical contact because with a smooth surface you can get more contacts. This product is especially good for those overclockers who want to overclock to the maximum. For those who lap your processors, you will need this to smooth the surface where you have sanded to achieve a higher overclockability. After using this, you may not need a thermal paste after all because the uneven surface has already smoothen out.

For a 10cc bottle, it would cost 8000Yen which is US$78
