    DISCLAIMER: This mod is NOT officially supported on the Macbook Pro 2019 16'', YOU assume all the risk and liability by attempting this repaste/mod on your own laptop. This thread was created merely to guide people on how to repaste/mod their 16'' Macbooks!

    If you have never used liquid metal before it is advised that you read up on it, it is a conductive liquid, so if it is accidentally spilt on any components, motherboard etc, it MUST be cleaned completely before turning on the laptop!


    Things you will need:

    Liquid Metal - preferably thermal grizzly conductonaut.

    Some sort of earbud to apply the liquid metal with.

    Some sort of tape, Kapton tape is advised. Although adhesive tape will work fine which is what I used. You can alternatively use some form of conformal coating which can be found on ebay or amazon.

    This shouldn't affect warranty as Apple does NOT disassemble these machines due to the convoluted assembly process.



    Disassembly & Application of LM

    You will need to disassemble the laptop almost entirely to take the heatsink off. Apple ingeniously thought it was a good idea to place the heatsink screws on the other side of the motherboard!

    First you'll want to use a Pentalobe 1.2 Screwdriver to open the bottom screws securing the macbook pro lid. Once you have done that you will need to lift the bottom lid at a 20 degree angle, this can be done from using a spudger on either-side of the airflow grills. Now you need to pull the lid towards yourself, this may require a bit of strength lol. Once you see the lid move down and hear a click you can lift the lid.
    Do NOT lift the lid too much when its latched at the top otherwise you will dent the top of the bottom base and bend the bottom cover!

    Now you should be looking at the internals, aside from the massive battery and big woofers there are a countless number of screws you need to unscrew before you can even think of taking the motherboard out! Luckily I have circled them all to make it easier for you, please organise these screws, most of them vary in length and size:

    [​IMG]


    So now that you've successfully removed 30+ screws you need to remove all the ribbon cables and for some reason there is quite a few of them. Now would be a good time for a break, lol. I've circled the ribbon connectors that need taking out and I've labelled them to make it easier for you. Please be very careful with the battery connector. One side is soldered directly to the motherboard, I almost ripped mine upon removal!:

    [​IMG]


    Who would have thought! 19 ribbon cables, Apple this isn't a phone its a laptop, please design it that way! Now that you have all the ribbon cables safely disconnected you can finally remove the motherboard. What I did was bend each ribbon cable off the motherboard so that I could just lift it out, like so:

    [​IMG]


    Now you can finally access the screws behind the motherboard lol. 2 hours+ of work just to remove a heatsink! Great job Apple!
    I have highlighted the screws that will need removing. Note that the cpu and gpu brackets come off, these apply direct pressure to the heatsink, the screws under the gpu-side sticker have been highlighted:

    [​IMG]

    You should now should now be able to remove the heatsink. I lifted and turned the heatsink ever so slightly to remove it. If you try lifting it directly you may bend it, bare in mind this heatsink is very thin!
    You will now end up seeing the worst thermal paste application possible:

    [​IMG]


    Now you can clean up that gunk until you end up with very clean/shiny surfaces:

    [​IMG]


    If you are using metal paste you will need to cover the capacitors next to the AMD GPU die, this is so that you don't short out the GPU with liquid metal!
    With the liquid metal applied and the capacitors covered your motherboard and heatsink should look something like this:

    [​IMG]


    That's it! You can now assemble the laptop back together. Remember to plug in all the ribbon cables and put the screws in the correct places!


    My idle temperatures went from 70c down to 50c after applying the liquid metal. On load the CPU can utilise around 65-70w compared to the 50w before LM. Unfortunately, the laptop still thermally throttles due to the heatsink being saturated by the insane heat the CPU gives out. When the fans kick in my 9880H levels out at around 3.3-3.4GHz, a big improvement from the measly all core 3GHz it was spitting out before. Multi-core scores have gone by around 20% even with the thermal constraint.

    Is it worth it? For multi-core loads, such as rendering and virtual machines it most definitely is.
    However, for gaming and light loads you should forget about it. There is not much point.

    I hope you enjoyed this detailed guide!

    Hi Bro. Useful thread to the extent that the teardown guide gives me even more reasons to hate Apple than I had before I read the OP and viewed the images. Nice job on it.

    But, I am really curious why you even purchased this in the first place. It's clearly severely overpriced and poorly made (speaking of the overall engineering abortion that it is, but not the excellent materials it is constructed of and chassis fit/finish quality) and offers poor value overall. What were you thinking, bro?

    The bottom cover really needs some ventilation grilles over the fan intakes. Those are choked off even worse than the fans were on the Tornado F5. That might knock another 15+ °C off the temps if the fans could actually breathe a little bit.

    I would've donated in a heartbeat if I had any money but I am broke beyond belief as I bought this laptop and then lost my job a week later! Just PERFECT heh? Once I get my replacement laptop from Apple I might sell it if I get a good price although it's not an easy sale due to how expensive it is.

    Did the new model need to be replaced, or is it the newer system has not been received yet? Seems like a long time ago if you are still waiting for delivery of the newer model.

    Edit: Nevermind. I stumbled onto the answer in another thread.

    Why would you need to do this ? It already has the best thermal engineering ever. o_O

    I think we're similar in that respect. I also love hyperbole. (Which might be obvious to anyone paying attention.)

    That is not thermal paste. It is a proprietary blend of magic pixie poop. It makes it special. And, you removed it. :mad:
