    Lap it on a glass surface to make it totally flat and use coolabs as a paint. You don't need big quantity.

    Flexni,
    This is something better done by hand as nik says, I have purchased lapping kits before that included a piece of glass and assorted wet/dry sandpaper, I lapped a Q6600 and Thermaltake heatsink with it, in the bathroom sink the water washes away the fine particles so they don't scratch the surface of what your lapping, of course if you plan on selling the cpu later it will look like a smooth brass/copper surface without identification makes

    Yoo Flex I made a prime run as u mentioned earlier, it seems i got a few errors as expected. Im also thinking of getting my last scores removed as im not sure if I was 100% stable at that time. I did a 4,9Ghz run with prime and that one was stable but after that it wasnt. It seems from there on that I need to fine tune everything much better.

    Flexy, do not use any Dremmel. You have to be patient with this to do a good job. First you can use a horizontal glass surface. You take a piece of sandpaper and using sticky tape you stick it on the glass. Then you sand to one direction from you and away or from away to you. Do not just scratch back and forth. Only one way with stable speed and try to use the same force pushing on the center. Count 5 - 6 times and rotate the heatspreader 90 degrees. Do another 5 - 6 times and rotate and so on. If you don't rotate there is a chance to have a perfectly flat surface but with inclination to one direction, meaning from North the height will be 2mm and to South or East 1.5mm. That means that your waterblock will not put the same force to all the surface evenly. That goes for the first sandpapers, the rough ones that will take out material and will make all the nickel dissapear. After that pure copper comes to the surface. Now you can use Menthol's way with water to remove the small particles. I have used that one but there is a drawback. The water oxidates the copper and before you apply coolabs the copper has a black or rusty surface which is not good for thermal transfer. Instead you can do something else but you have to use lots of sandpapers. With sands number 1500 and above you can stick them on the glass of your window. Again you sand from up to down or down to up. With a piece of cloth you take down all the particles from the sandpaper and your heatspreader. The vertical surface helps that most of the particles fall down so you don't need water. You have to change sandpapers continuously and almost not use the same surface again. By the end you have a perfect finish. You don't need to go up to 6000 and you need lots of patience. Good luck

    Crimson you don't have to remove your scores. By the time you did it, was ok. That's benching mate.

    tnks nikosa my friend i will let you know how it turns out ! +rep

    crimson m8 post up screenie what voltage was 49x stable? and temps?

    and noo dont remove scores man...
    benchin is benchin! if the run completes the score is valid stable cpu or not
    for example @ hwbot if you can boot 5500mhz and can save cpuz validation and submit and right after that you get BSOD..then its unstable but valid submission
    checkin stabiity is something totaly different
    also...let the prime run for 12hours with no errors..then you can call it stable

    Hey Flex, thanks for rep mate! And remember. Do not try to lap the inside of the Heatspreader. It's impossible to make an even surface there. (As much as I wish to could do it also)

    This is what I use for lapping the IHS

    I use two fingers light pressure in a circular motion. I do 1 session dry then polish with a drop or two of water. I do use a glass surface. If you use a back and forth motion you will tend to slope the IHS. Mic it. Check out most lapping machines rotate the part in all directions.
