    Liquid metal won’t damage your heatsink if it’s made of copper.

    It's not so rosy though, is it? The GaCu alloy that forms on the copper heatsink has lower conductivity than copper and therefore will compromise thermal performance, and can't be easily removed. It may also cause glueing effect making the heatsink difficult to remove, potentially causing damage during removal, and the alloy layer itself can be rough and uneven.

    I have used Liquid metal many years. And one thing for sure... Heatsink works exactly as the day it arrived with the laptop brand new.

    Heatsink from my Alienware 17 from 2013 after near 4 years with it. The grayish color is what it is only a simple discoloration due the Gallium. But the cooling capacity is exactly as before. No change

    Same also for the Heatsink in my Clevo P870

    I trust you measured this using specialised equipment?

    Clearly both heatsinks had to be sanded to look nice, the scuff marks are obvious. The Clevo heatsink looks terribly uneven, the alloy has holes in it. In the thread posted above alone, and not just there, people are saying they wish they didn't go down the LM route.

    I personally wouldn't unless I needed to run CB20 like loads for extended periods of time or lived in a very hot climate without air conditioning. For other scenarios a non-LM paste gets the job done for for this laptop with virtually no risk or hassle.

    I trust what temp I'll get after new application of Liquid metal. If the heatsink wasn't flat or even after the change of liquid metal I would get temp I can't control in my benching. And the grayish color on heatsink help you get even better results the second time you put on new liquid metal.

    If you don't know how to do it in first place, then it's a risk... http://forum.notebookreview.com/threads/misjahs-guide-on-how-not-to-liquid-metal-repaste.805338/

    Thanks, @hmscott summed it up well:

    All those measures people take just serve to reduce the risk rather than completely eliminate it.
