[demon-eater]

Hi I noticed that since i chipped my 1.2axia I now have a small pit as i shall call it on my HS where the chip would make contact with it.. now when i use my duron its affected by this because one of its corners are where this spot is on my heatsink... now what kind of sand paper should i use to lap this baby?? as some have reported their are grooves on the bottom of mine as well but never really hurt my cooling till now so where can i get sandpaper and what grit should it be??

I live in Pennsylvania and would like to buy it from a store.. cause i hate waiting for stuff to get shipped.. plus i need this done by friday cause thats when my 1.4 ahjaY is coming yipeee

Go to the local hardware or hobby store and pick up a sheet of 3M 600 or 800 grit Tri-Mite (Wet-or Dry). Tape it down to a flat surface. Put 2 or 3 drops of dish liquid in a small coffee cup (clean) and fill it half way with tap water. Stir to mix in the soap. Pour a small puddle of it in the center of the sheet, place your SK-6 on the sheet and holding it firmly, to assure it is resting flatly on the sheet, slide it around in a circular pattern, allowing the weight of the SK-6 to provide the downward force upon the paper. If yyou press down too hard, you may wind up grinding a convex pattern. Every ten passes or so, rotate the SK-6 90 degrees, regrip and repeat. Eventually, you will see the water take on a gray (if aluminum) or brown (if copper) tint. That is the particles suspended in the solution. Rinse the sheet with more of the soapy water and continue. The paper will slowly lose its biting nature over time, much like switching to a finer grit. Check the base of the SK-6 from time-to-time to observe your progress. In time, the base will have a smooth, matte, regular finish all over it and the marks will be effaced. Some people choose to use continuously finer grits until the base has a mirror finish, suitable for combing their hair in. Having gone that far as well as only to the matte finish point, I personally have not seen any improvement in thermal efficiency with the mirror finish, so I am not covering that process. Rinse the SK-6 in hot tap water until it becomes almost too hot to hold to remove any soap residue. Wipe it as dry as possible with a paper towell and let it sit until it has cooled off. At that point, enough of the moisture should be gone to re-install it. before doing so, wipe the base one last time with a paper towell wet with a good solvent like Acetone, Methyl Ethyl Ketone, Brake Cleaner, Degreaser, even good old Gum-Out from the automotive store. Avoid "Environmentally Friendly" organic degreasers. That will assure any loose oils are removed. Apply your thermal grease of choice to the CPU core and remount it.
