I Made LIQUID METAL for the Processor!


Hello everyone! In this video, I’m going to show you How I made liquid metal for computer Central Processing Units And how I tested it’s thermal conductivity In case you didn’t know Modern computers transfer heat from CPU to radiator through a layer of thermal interface material Most frequently thermal grease is used as such a material And obvious disadvantage of thermal grease is that it has very low thermal conductivity which at least 5 times slower than that of tin solder It is so due to the powder components it contains It is especially useful in our days because INTEL CPU are not soldered to heat transferring caps Otherwise, they are glued to it, with silicon And heat is transfer through thermal grease because of that, heat is transfer not very efficiently to the cap Besides thermal grease, there also exist liquid metal, which transfer heat much better than the thermal grease However, it is 10 times more expensive, that is why I decided to make my own liquid metal and *upload?* it, to share with you, my viewers, all the secrets of it’s production Nowadays, liquid metal sold in computer shops for *???* users, it is gallium based Gallium is a metal, which has a very low melting point of just 30℃ However, when held in hands, your gallium does not melt as quickly as one will do expect I think you have seen lots of experiments with this element If gallium is *wrap?* against another metal such as indium from the group 13 in the periodic table They will form an alloy, which is liquid at the room temperature, In the place of our both metal contact It can also be called an eutectic solution It is 24.5% indium, and 75.5% gallium It’s melting point is 16℃ It’s interesting that the piece of gallium goes down significantly The habit due to the distraction of it’s crystalline grade At the room temperature, this alloy remains liquid But, only at 16℃, which is not that low, for instance, when the centralized heating system is shutdown, this alloy will solidify, on a chilly summer day That is why in order to further reduce melting point of the alloy, engineers have come up with an idea to add tin to the alloy of indium and gallium The alloy is 68% gallium, 22% indium and 10% tin It even has its own name, galinstan. This very alloy is used as thermal interface material, and is called liquid metal It is quite easy to make, you just need to mix all the components and heat it up First, I heated up the alloy in a heated bath, however beads of tin didn’t dissolve But, when I used a burner, the alloy mixed together well and became smooth Melting point of such an alloy is much lower than that of the previous alloy, and it’s about -19℃ However this fact is open to debate because *???* of the melting point might also be interrupt to bismuth and antimony impurities that the metals may contain That is why there may be some flotations However, *that obtained?* galinstan wets difference surfaces very well That is why it is easy to distinguish it from mercury Besides, in contrast to mercury, galinstan is absolutely safe and non-toxic This alloy can be used for draw conductive tracks on paper, their electrical resistance will be much lower than that of graphite tracks Besides, this alloy isn’t very viscous, that is why it can be easily sucked in with an insulin needle Now, let us test heat conductivity properties of such a DIY alloy I have prepared such a experimental setup, I’m using my old core i3-540 CPU manufactured in 2011 I’m using no ordinary radiator otherwise such a nickle plated one which will contact with the CPU An aluminum radiator is not to be used with liquid metal Because gallium which it contains destroys aluminum’s crystalline grades, making aluminum fragile To demonstrate how this happens, I took one aluminum radiator, and put a drop of galinstan on it After that, I left it like this one for a week One week later, you can see that the galinstan drop has slightly oxidized, and the radiator itself has become very fragile It is very easily breaks in hands, imagine what it will be like if your computer’s cooler and radiator suddenly fell off A nickle plated radiator can easily prevent such a problem After preparing the setup, first, I applying a regular thermal grease to the CPU which comes along with it as a thermal interface material

  1. Your assumption with regards to the soldered part of your CPU die is in fact correct. Chipmakers who solder their dies to the heat spreader generally use a very pure Indium solder. Also, the gold looking area where the solder is on the heat spreader is pure gold. It's an interface layer for the Indium to stick to as it won't adheer to the nickel plated copper. Great video!

  2. @8:10, no, you showed that it was 54°C before :/
    and this is an insignificant difference (or at least not worth it)
    (but let's guess you run other tests, and got 58°C)

  3. GALINSTAN is also used in thermometers instead of toxic mercury. I used it for fine on my 8700k a year ago. Optained it online at chemical element store. http://svetprvku.cz/vyhledavani?controller=search&orderby=position&orderway=desc&search_query=galinstan&submit_search=

  4. You don’t need tours scalpel. You can use a dedicated tool to remove cap from the cpu. Or hammer 🙂

  5. DAMN you, 2010 MacPro tower and your must-be-aluminum-because-it's-the-only-one-Apple-makes heatsinks!
    Guess it's time to look into DIY plating.

  6. Dont do this i did same that you do but when i applied the liquid mattel i boot my pc and played gta 5 then the liquid mettel flowed on to my mother board and shotcircuit it and unsolder some components i wasted my pc becouse of you fool

  7. I am confused. With thermal grease you got a temp of 54 degrees C and when you used Gallium you got 52 degrees. You mentioned though that you got a 48 degrees C with Thermal grease but even then the difference was hardly anything great. I know that it does work as I have used the Thermal Grizzly Liquid metal on my 8700K and dropped temps by 18 degrees C so maybe I missed something or miss heard the temps..

  8. Thermal Grizzly Conductnaut: 73 W / (m · K)
    Coollaboratory Liquid Ultra: 38.4 W / (m · K)
    Coollaboratory Liquid Pro: 32.6 W / (m · K)

    Can you explain then?

  9. Next video. I made the T-1000!

    BTW,

    I subbed.
    Excellent video.
    I'd wish I could buy all that stuff in my country, but, I doubt it.

  10. Английский какой то ломанный и неправильно звучит…

  11. Do a video on how you can make an aluminium cooler immune to liquid metal corrosion by applying a different metal as the contact metal.

  12. The thermal conductivity of your liquid metal mixture seems quite low. Thermal Grizzly Conductonaut claims 73 W/mk thermal conductivity, whereas you claim only 17 W/mk for yours. If this difference is true, it easily explains why the temperatures hardly changed at all.

  13. If you want to start selling kits of vials with the appropriate amounts and syringe(s) I would definitely be interested in buying. I want to liquid metal basically all of my game consoles and have no interest in paying the price of what Thermal Grizzly wants.

  14. Its not safe unless it dosnt get into any body opening , wounds or your eye. You should because of healthy reasons,wash you hands after handling with gallium.

  15. You can tell this guy is not particularily savvy within the anglophone tech world by his calling of the cpu die a "cristal". Hes long ago been won by chemistry haha

  16. I'm happy that most comments are not about his accent. Every YouTuber that has a Russian accent gets made fun of

  17. The operating system probably have a speed throttle feature where it uses the CPU aggressively until a certain temp limit then speeds it down to avoid overheating. So, the experiment should have speed up the Vegas video production and that is a missing information on the video. Would be nice to have that for the paste experiment.

  18. Thermal paste: 52°C, 54°C
    GalliSn: 48°C, 52°C
    A difference 4°C isn't substantial. Scientifically it might be 'significant' but I wouldn't call this useful.

    With such a small difference in temperature between tests, it makes you wonder if the ambient temperature changed in the time it took to setup for the next test, which would result in difference of that magnitude meaning the GalliSn made no significant difference.

  19. Really rich and a good experimentor !!!!!
    Love u fnrd keep on doing such experiments we all love u ……..

  20. I bought gallium, magnesium , tin and zinc as an interested man. Just one more and i will be an evil technical, maniacal and solenoidial cpu, genius.

  21. I want to delid my i9 9900k, then i will make my own liquid metal, put it in seal up and then put the CPU back in the motherboat.

  22. GALLIUM is a bi-product of aluminium smelting. Where is it all going? I believe the metal industries are doping some conductors with it! Although it makes then brittle too the savings in conductivity is worth it. Now Gallium is amazing!! Gallium-Aluminium is a superconductor at -295 Celcius. Gallium Nitride is a better semiconductor than silicon. And everyone is saying it will replace Silicon chips. Also there is an invention of a gallium alloy being used as "wireless power" cool Hu.

    I long for my idea of having gallium alloy alternators in space. Creating transmittable electricity. I dreamt the exact method. It was like a revelation. I asked if they could show me how we can create massive power in space again. They the entity in my dream replayed it like a video!! Exactly.

  23. Not a great scientific process you messed with the conditions and aplication of your setup so results are of questioned worth.
