    I have read various discussions on 'lapping' a heatsink and am still undecided whether it is worthwhile.

    One website pointed out the following:-

    >Remember that the surface of your CPU is not flat. So >it is no use even thinking of making the heatsink base >perfectly flat as that could make the contact area >between the two even worse.

    I have just removed the "Thermal pad" from the base of my Miprocool and have only to use cleaner to remove any remnants of the pad.

    On close examination the base of the cooler where the thermal pad was fitted is very well finished and to my mind does not require any lapping at all, indeed it is possible lapping might be detrimental.

    Is it really advisable to achieve a perfectly flat highly mirrored surface to the heatsink base when the surface of the CPU has lettering on it and possibly is relatively uneven?

    What are your experiences temperature wise of using a lapped and unlapped heatsink?

    Hi Harry,

    of this discussion never before i saw a little.
    Just remove the original thermal pad from the aluminium cool and use nail-varnish remover to clean it up ( also the processor heart).
    The cooler is beautifully plane an must be checked no more.
    Use the arctic silver 2 thermal paste to get the best performance.
    If trying it the first time, just have a look on this site:

    Hello Dirkvader,

    Thanks for the URL for the Arctic Silver instructions, I have already printed out the instructions. <s>

    I must agree with you that the finish on the base of the Miprocool is excellent.

    I am just about to order some Arctic Silver II.

    Harry
