    As many of us have learned, if you have delidded your CPU and used a liquid metal TIM, when you go to change your configuration, the TIM can leave a lot of discoloration. So folks also use liquid metal TIM on to of their integrated heat spreaders as well. And this can lead to issues if you are trying to read the serial number on the CPU. der8auer shows you how to get that nastiness off, if you really need to. 10% hydrochloric acid makes for a good start!

    Check out the video.

    10%! :cautious:

    Seems like you'd be just as likely to burn off the serial numbers instead of making them easier to read

    He was using 4% in the video, but said not to go over 10%, but ya I would be worried about the etching coming off.

    The etching should not come off. You would then be removing material from the IHS for that to happen.

    If you RMA the chip, you need to have the serial number readable for the company to accept it for warranty work. If you use liquid metal then it has a very high chance of cosmetic discoloration occurring that will make the serial number on the chip to be unreadable. So the video was showing a method of removing the discoloration so that the chip's serial number can be successfully read and thus make your RMA a smoother process.

    It is the YouTube hit squad that will be after you if you go a bit "old school" when it comes to this stuff. All those folks that have 10X more time and experience will come in an tell you how wrong you are in your videos. The struggle is real.

    Liquid metal scares me. I'm going to keep using the standard stuff.

    Wait, why would you use liquid metal between the IHS and heatsink? Liquid metal is going to eat away at copper or aluminum.

    Aluminum yes but copper... What do you think the IHS is made of?

    Yeah, I would highly suggest you folks NOT do that. Of course you can, but the amount needed could opens up all kinds of other issues inside your system. That shit gets everywhere...quickly.

    This is the [H], we all lap our CPUs to start with.

    Methinks if CPU serial numbers are an important facet of your life, then you need to get out more.

    Yeah, that's what I was getting at. I thought 10% might be strong enough to etch metal in a reasonable timeframe
    Wrong acid :)
    https://en.wikipedia.org/wiki/Hydrochloric_acid

    Looking at that article it seems like I am overestimating the risk of damaging the etching though since 18% is used for the "pickling" of steel

    The IHS is plated with nickel, though.
