    Ok, I'm in the process of repasting my 940XM on my m15x but I'm not sure how I should go about it exactly. Should I put thermal paste on the heatsink, or on the processor shield itself? How much should I put? I noticed there was quite a bit when I took my laptop apart and scraped off the old thermal paste. Will putting less lower my temps? Will one dot in the center suffice? Thanks.

    Did you ever find that guide. I am searching for exactly the same information.

    Thanks,

    Yeah it's a fantastic guide and very well written. Should help you with all your repasting needs.

    I've always done it like so:

    Remove all old paste from CPU and heatsink. I use a little piece of plastic because it won't scratch the metal. Make sure the CPU die (the shiny part) and heat sink contact surface is nice and clean, rubbing alcohol and a lint free cloth usually helps.

    Then I use a cotton swab with a layer of plastic cling film rubberbanded over the cotton to spread as little paste as I can get away with in an even layer by dabbing it across the die. This helps you not getting paste on anything but the die part of the CPU.

    I also do the same to the contact area on the heat sink, but tend to leave a little less on this part. You just want to fill out any scratches and have an almost transparent layer across the whole thing.

    Make sure you have the heat sink as close to the position it needs to be before you touch the two parts together. Pressure from the spring loaded heat sink screws will do the rest.

    Turn the screws slowly the wrong way while keeping pressure on them and you should feel a small click when they line up with the threads, then turn them into the threads. This should help you not strip anything.

    I then screw them in in an X pattern a little bit at a time:

    1 4
    X
    3 2

    This has always given me very good results and low temperatures.

    I think the key element is to use as little paste as possible in an even layer to get a good contact. The paste will transfer heat worse than both the die and the heat sink, so getting them as close as possible is crucial.

    Oh, and always use an antistatic wrist strap.
