    In order to clean the dust globs from my E521, I decided to remove the CPU
    fan. The procedure requires breaking the thermal grease bond to remove the
    heat sink. Instructions from Dell are at After
    finishing the cleaning, I got to wondering if the thermal grease should have
    been replaced. There is no instruction to do this. The heat sink is held
    tight to the processor with spring loaded screws. Should the thermal grease
    have been cleaned and replaced?... Dean

    Probably not strictly necessary, but I'd certainly advise doing it. Gently
    get it off with a cotton bud and some acetone or cleaning alcohol, slap on
    some silver, spread it with a credit card, whack on the CPU, and you're

    My least favourite part of building PCs.
