    This is actually sad and just proves ASUS can't be bothered to design their cooling solutions properly.

    My example, a G703GX with stock paste would heat up to throttle levels very quickly and jet engine noise levels. Only after I switched to liquid metal and tweaked voltages it runs good, no throttling and stays relatively quiet even under load.

    Liquid metal escape risk can be greatly reduced by having an even heatsink with a flat fit, and there's barrier methods as well for insurance

    Loss of liquid metal volume (or. "drying out") by alloying into a new copper heatsink will be a bigger problem. Every install I've done has needed to be checked within 3-6 months and has required more to be added.

    Maybe they will be nickel plating their heatsinks? But that, and better heatsink fit QC, and barriers, will all add to cost.

    Interesting. I do not think it's a good solution because it may leak over time more easily - yes, yes, you can put some silicone barriers around it but as many people know the manufacturers aren't able to reliably apply even regular thermal paste, resulting in one person seeing 98C on his laptop and another one seeing 89C when playing same exact game on same exact model at same ambient temp so there would definitely be issues with quality of LM application and the quality of barrier around it. Plus as people have pointed out LM does react with copper over time so this will require extra coating on top of copper or aluminum heatsinks. Plus an application of a clear coat paint all around GPU and CPU in case if it does leak so it would not short out anything.

    I think more reliable solution would be to use a slightly thicker Carbonaut pad, something that would last long and would be more consistent (it will be easier to apply and can compensate for small variations in heatsink mounting pressure if it is thick enough) and cost cheaper to use.

    Quote: "The problem with Liquid Metal thermal compounds is the risk of spillage, misapplication of leaking over time, as by its very nature liquid metal thermal compounds are conductive. To tackle this problem, ASUS has created precision machinery to apply the right amount of liquid metal to each system and a unique internal frame that prevents liquid metal leakage over time. Thanks to these changes, ASUS is now able to produce systems with liquid metal thermal interfaces without decreasing the reliability of their systems."

    well well, looking at their measures one might think they scoured the web for potential solutions and stumbled upon several NBR threads :p
    a.k.a. how to apply LM properly and foam dam barrier ;)

    That's awesome, let Asus and the other makers work out the manufacturing details to successfully use LM, and let them be responsible for the warranty support.

    I wonder if this LM option will bring about the 30 / 90 day warranty?

    I'd recommend getting the vendors extended warranty at purchase.

    yep, be sure to expect a price bump when keeping the same warranty length on these new machines...

    The chapo way. They just eat from the small remaining cooling headroom they gave this laptop models. Why not instead offer better cooling? As it is now, there is not much left an end user can do now to improve the cooling.

    This brings me to another problem as well, what if the cooling needs to be maintained because its filled with dust...
