    Did the New heat sink had protective plastic film on that gray thermal compound ?

    If you removed it then its OK.

    no protective plastic film
    Do you think I can trust this original thermal compound?
    Assemble it with this thermal compound?

    When cleaning, don't use any metallic object (screwdriver and the like) to remove the compound, otherwise you'll hurt with scratches the copper surface. Use a plastic tool or object.

    Arctic Silver is good just remember just a small dab in the middle of your cpu is plenty, in this case less is better ! ;)

    I've cleaned and reinstalled several heatsinks lately. I've found one of the best things to clean the top of the cpu and heat sink surfaces is just a plain, dry, cheap kitchen paper towel. The ones on a roll that tear off 1/2 a sheet are the perfect size. It's just rough enough to take off the old heat sink compound, but won't damage the metal surfaces.

    I have heard that the Arctic Silver tends to dry out over time and will need to be re-applied. That MX-4 is supposed to be guaranteed for 8 yrs, because it does not dry out....... for what that's worth

    That's a 'famous' Chinese copy of Artic Silver! Any real Arctic Silver will not dry out!

    I use Arctic silver for years and never had a problem, just only assure that it's original but copy!

    Personally, I would not use the aftermarket compound (GD-460)
    As a rule of thumb, (my thumb) the thermal pads attached to OEM heat sinks are sufficient and meet the manufacturers (engineering) specifications.
    Bottom line, I would remove any clear plastic layer to expose the thermal pad, then attach the device as is.
    Are there better alternatives? Of course there are, but under normal circumstances (no overclocking) (clean heat sink and rotating fan assembly) everything should be fine as is.

    @ManyDimensions: Been there...done that. After about 6 months in, using the stock Intel heatsink goo, the goo dried out and the CPU started to overheat.
    Swapped it out with Arctic Silver and everything's running fine (About 2 years now)

    Of course, Your mileage may vary, but this is just My experience.

    BTW: Welcome to MDL :)

    I change my compaund every 3 years. It is a long time. So I don't think quality matters that much.

    If you ever need new thermal compound you might try out Thermal Grizzly Kyronaut a German high tech product NOT made by VW. ;) I tested it myself and I have 2-5 degrees Celsius less then with Arctic MX-4.

    IMHO the quality of thermal paste is far overestimated. It is there to cover micro scratches that's all.
    Hence it is suggested to use only a little of it.

    The heat flow is proportional to the contact surface and the thermoconductivity depends on the used martials of the cooler. The cooling issue comes from non planar surfaces or a not properly attached cooler. (and later form dirt inside of the fans)
