Liquid metal can also damage solder joints, so it's not a good idea to use it for shunt mods.

[@johndrachenberg2254]

Steve, would you please do some tests with lapping cold plates? It would be interesting to see how much a mirror-finish affects temperatures. You'd probably want a control test, a lapped cold plate only test, and finally a lapped cold plate and lapped CPU IHS test.

[@Visentinel]

Hey Steve iv seen some concerns and photos of the effects of liquid metal to the die itself. Can u please look into this if there's any truth or anything to worry about?

[@Zarcondeegrissom]

great dive into the potentially controversial topic. I do suspect that the depth of tainting is only atoms thick beyond the imperfections of the copper surface. And even then, unless a heat pipe is already on the edge of failure due to excessively thin outer walls, the atoms thick tainted copper outer layer will not cause any problems at all. Also, given the nature of LM attoms filling gaps between copper atoms on the surface, it may actually make the surface a tad better for contact area to whatever TIM is later used (albata possibly immeasurably outside of an ultra-precision lab test), due to LM atoms being better at conducting heat than a void between copper atoms, lol. Great vid GN crew.

[@bparks2193]

[@friedhelmschroter8124]

In my understanding the corrosion/alloy effects of liquid gallium with solid solid aluminum, copper and nickel (actually nickel plated on copper) have been fully described in the video as 1) Aluminum: destructive corrosion (solid aluminum alloys with liquid gallium and the resulting brittle alloy gets attacked by moisture in the air with final effect the aluminum gets "eaten away", similar like solid iron corrosive rust oxidation with gaseous oxygen, but at a much faster rate) 2) Copper: also strong reaction, but non-destructive and also thermal degradation is negligible (copper alloys with gallium to CuGa2 and this alloy stays as a mechanically stable layer on the copper, thermal conductivity is reduced to 95 W/m-K compared to 400W/m-K for copper, but due to the thinness of the CuGa2 layer no measurable/see-able effect on the chip temperature) 3) Nickel (actually a thin plated layer of nickel on solid copper): A very slow reaction between nickel and gallium causes some not harmful staining of the nickel and the plated nickel layer seems to suppress that the copper alloys with the gallium In my understanding this video has not at all addressed what above 3 corrosion/alloy reactions mean for the thin TIM layer of liquid metal. Liquid metal stands in my understanding for all metal compositions that are liquid at room temperature. No fixed/concrete composition exists/is defined. Liquid metals based on mercury need special care because of mercury's high toxicity. Generally considered as nontoxic are liquid metals based on gallium. The name Galinstan stands for a 3 metal composition mainly of rather expensive gallium (Ga 69~95%), but also indium (In ?%) and tin (Sn 0~11%) with the specific composition Ga 68/69%, In 21/22% and Sn 9.5/10.5% showing under vacuum the quite deep melting point of -19°C. However there are also 4 metal or even 5 metal liquid metals mentioned in this German patent (application: thermometers for several purposes/temperature ranges in the total temperature range of -20 to +1.200°C, patents.google.com/patent/DE10321843A1/de). As additional metals zink ( Zn 0~29%) and plumb (Pb 0~10%) are addressed for specific purposes and in another patent bismuth (Bi) and antimony (Sb). The patent also mentions that a 4th or 5th metal may allow to reduce the percentage of expensive gallium to 50% with only minor degradation and that the way of processing/mixing results in differences, for example by addressing the strong oxidization of gallium with oxygen. In my reading liquid metal is not liquid metal, but there exists a multitude of possible metal compositions around gallium as the main material which I see also in application as TIM, where CoolLaboratory offers today 3 compositions, Pro obviously for lowest thermal resistance, Ultra probably for lower cost and on the newest composition Extreme CoolLaboratory claims they have addressed also the longevity. The harmful consequence of gallium's strong reactivity seems to be that several people have proven by video that the applied liquid metal got hard/"dried out" while others even commented when they opened the gap/TIM and checked visually the liquid metal was gone completely. In my understanding such hardening of the liquid metal happens only when applied on copper (does not occur when applied to nickel plated copper, this means especially the IHS) and I understand the underlying process for the hardening is gallium leaves the liquid metal and migrates into the copper to form there the solid CuGa2. For the quite thin TIM layer this means the percentage contents of gallium is permanently/quite fast reducing and when the gallium percentage falls below a certain percentage (different for each composition of liquid metal) it becomes hard and the hard remains of the liquid metal are quite difficult to remove from copper (the people even claiming liquid metal disappeared completely may have difficulties to see the remains of liquid metal by their eyes, especially when the gap was extremely thin and the color of the remains may be similar to CuGa2). In total I see following 2 problems when applying liquid metal as a TIM: 1) Only on aluminum: destruction corrosion and 2) Only on copper: hardening of the remains of very thin liquid metal once a certain amount of gallium has moved into the copper it is in contact with to form there the solid CuGa2 alloy. This hardening when applied on copper requires to re-apply the liquid metal generally every 6 months (in extreme cases even faster) to avoid the not easy removal of hardened liquid metal from copper.

[@hendystark8333]

so it's completely safe to use LM in laptop (with copper HS), as long as it's reapplied every 6 months. what is this extreme cases? thanks!

[@eniff2925]

So using it on the die of a microprocessor under the nickel plated IHS is mostly safe and doesn't degrade the materials. Have I understood it correctly?

[@Juwce_86]

@@eniff2925 Yes. I did this with a de-lidded 7700K with Thermal Grizzly which i bought new 4 years ago. If you do as I did and as the rocketcool or similar recommend to reseal the heatspreader after application then its a once off process. Im one of those OCD people so I would reapply thermal grease once a year after the delid and at the same time inspect the 7700k for any damage. None and literally no drop in performance. Infact before I upgraded earlier this week 18/6/2020 I did an experiment with liquid mental on the heat spreader to AIO (for about a month) and yes, the results were as expected even better. Do I recommend having liquid metal between a cooler and processor? Probably not. But if you are just doing a delid then yeah man just do it.

[@webx135]

Commenting on a older video, but this is a great reference and wanted to mention something with regards to bare copper. When the liquid metal alloys with the copper, the oxidized result is sort of dry and chalky. This is normal, but it could hurt performance. What you want to do is ALLOW this to happen initially. Give it a few weeks or so to "soak" and bind. Once you've given it some time, you want to open it up again. Remove the existing liquid metal and clean it as well as you can like you would normal thermal paste. Do NOT use sanding or polishing to remove the alloy stains. If lapping the IHS, you should lap it first. The idea is that we WANT that staining to stick around. It is only surface-level, is stable, and has done all the reacting/alloying it is going to do. That is, it isn't going to continue reacting the way it would with aluminum. So in essence, it has become a protective barrier, stopping further corrosion. After thoroughly cleaning the surface, simply reapply the liquid metal. At that point, the liquid metal should more or less retain its original properties from then on. If you had polished or sanded the staining off of the surface, then when you went to reapply the liquid metal, it'll just re-alloy and create the same chalky residue. You may still want to check the temps after re-application in case you need to repeat the process. But basically once the alloying process is "complete", the liquid metal is mostly just an alloy of elemental metals, rather than a complex emulsion or ceramic you would see with other TIMs. This means you shouldn't have to worry about decomposition or "aging". A couple other tips: - On the cooler, apply an amount notably larger than the die for the initial application. There will probably further reactions along the edges, so you want those edges to be outside of your contact zone. - To speed up the alloying process, you could do some thermal cycling. Running hot will speed up the reaction. Thermal cycling may help it expand/contract and thus fill tinier nooks and crannies. I usually do a batch video conversion, or do an overclocking stability test, perhaps running the fans lower. We basically want to hang out around 80-90C. Modern CPUs are OK with this, and LM works better at higher temperatures.

[@supercrazymario404]

After using liquid metal on a bare copper heatsink for a year, I noticed that the liquid metal had fused to the copper and became a solid similar to the chalky residue from the aluminum heatsink test. I also noticed that the thermal performance became worse over time because the liquid metal was no longer liquid and even with the heatsink removed and heating the surface up, the stuff didn’t turn back into a liquid. So I’m guessing some of the copper and galinstin actually changed chemically so now the only way to get the flat surface back is to scrape off the alloy of galinstin plus copper and not scratch the actual copper

[@levigoldson4242]

That usually happens if the copper had imperfections. Sometimes this is intentional to cut costs. I've been running the same liquid metal for 6 years on a pure copper plate with 0 problems. Still liquid.

[@dariobarisic3502]

@@khawajashaharyar9294 What's left of the liquid metal that's bridging the cpu/gpu die and the heatsink should be gallium deficient so it's not of optimal composition. Therefore, I would suggest cleaning it off with alcohol first and then reapplying. Is it absolutely critical to first clean of the remains? I have no idea. I would imagine gallium is used in the composition due to its low melting point so galium deficiency could case lm to not be so liquid anymore and that's obviously bad. In summary, cleaning it off first and then reapplying seems like a safer option

I have a der8auer i7 8700k Ultra with a silver IHS. The last weeks the temps kept rising until I couldn’t overlock anymore and figured my watercooling was busted. That proved not to be the case. I delidded the CPU and what I saw was nothing short of catastrophic. The LM was completely hardened and had visibly corroded the silver to the point of effectively having destroyed the IHS. The CPU is 2 years old. Replaced the IHS with a pure copper one and will delidd at least every 6 months now.

I used 8700K with delid and liquid metal for a year. I lapped both sides of the HS to copper. On the bottom between the core and the HS year later the metal was still liquid. But between the top and Noctua cooler (which I also lapped just to be sure), it dried and basically fused the two surfaces together. I had to use a lot of force to pull them apart, and after that I had to lap both surfaces again to get rid of it. But that being said, before I pulled them apart, the temps were still fine, so even when it reacted and dried off the thermal conductivity was still fine.

Bare Copper can suck a bit of it up, so the best thing you can do is add a bit more than you would with nickel plated copper. The mistake a lot of these laptop LM users make is in fear of LM doing a different short prone kind of migration; they use the complete and utter bare minimum amount of LM they can manage to get away with, and the LM dries up in a matter of months. Use a little bit more and just insulate the surrounding circuitry and you will be fine.

I used a product called Indigo Extreme on an old Core 2 Quad (stock nickel-plated IHS) mated with a copper waterblock years ago: that produced a metal film like a foil. It was difficult to separate the CPU from the block when un-mounting, but the material had flowed so well that the mirror-image of the markings on the IHS was printed onto the slice of foil that came out when it was disassembled. Weird installation procedure, but it seemed to work pretty well. Removal was mostly just peeling off the "foil"-- IIRC almost all of it came off in one piece, with a couple of extra bits that needed to be scraped free. Seemed like an easier thing to apply and remove than these liquid metal TIMs. Personally I went back to using non-conductive paste-- it's just easy / relatively risk-free and I'm not trying to set any overclocking records :D

[@Azzalus]

If the gallium indium mixture is reacting with the copper in a way that ends up plating the copper as you said, wouldn't it then become an almost perfect non reactive surface for liquid metal due to the plating acting like a barrier between the gallium and copper, just like the nickle plated copper?

[@johntorset3314]

When the copper surface on the cold plate is saturated with gallium then no more reaction will occur and you will get a cold plate finish with the same color as gallium. For first time application I have found that you need to apply a little more liquid metal than you would normally use to compensate for the copper/gallium fusing or else loosing a measurable amount of heat transfer from the IHS to the cold plate.

Here's a video of a liquid metal with copper reaction over a year: kzbin.info/www/bejne/fIibl5qKn62XedE Short version: gallium forms an alloy with copper over time (months, a year) leaving indium and other materials as a hard metal residue, which is difficult to remove and often not flat. Because of its surface shape, the residue has bad contact with the silicon surface and does a poor job of conducting heat. So the liquid metal appears to "dry out" and fail over time.

What's the point of lapping and trying to get a perfectly mating surface when dust in the air, fibers from application tools, and tons of other crap is getting between the surfaces?

I wonder what type of Liquid Metal Sony used on PS5..

[@Takashita_Sukakoki]

gallium based mostly

[@Ownage4lif31]

I still don't get why they did it. Watch it dry out completely in Judy 1 year of use!

[@brumby92]

I just bought myself a 4790k. upgrading from a 4670k. According to the eBay guy, this particular chip has temperatures in the 90's on his coolermaster CPU cooler. I was looking into delidding in case I got bad temperatures. Thanks Gamers Nexus for making it look easy, and for doing experiments like this. I'm about to swap the CPU's. Wish me luck! Also I die a little inside when you say Aluminum and not Aluminium. IIIIIIIIIIIIIIIIII

[@Supercon57]

Two days ago I popped open my Asus GL502VSK they I applied Conductonaut to, I noticed staining and freaked out a little Thanks for the video, it was very relevant to me lol

Steve, I haven't seen anyone do a review of the CooLLaboratory Liquid Copper - this seems like it could be a much better alternative to the current liquid metals that can be corrosive. Copper is likely more conductive but should not cause concern if proper application guidelines are followed just like other liquid metals. i wonder if this might be a good option for those who have had disastrous results with shunt mods using regular liquid metal?

[@Antagon666]

I did notice LM making alloy with copper, also corroding the silicon chip in the process, however the temps didn't change at all after a year in the laptop... Seems to make great contact still, till u remove it and look at the damage... However in legion 5 it's super worth it, went from 100°C at 60W to consistent 80°C at 80W on the CPU. Paste works good in there for 2 days, but then reaches unacceptable temps really quickly...

[@justanotherasian4395]

So basically what I got from this is, if I’m going to use LM for lowest temps, I use a cooler with a nickel plate, like bequiet’s liquid coolers

[@HikingFeral]

If you inject an aluminium padlock with gallium, the padlock becomes so brittle that you can crush the padlock into a powder with your hand. If liquid metal contains gallium...yeah

[@ronniem4487]

So basically what to use Liquid Metal on: Nickel = Excellent Copper = Good Aluminium = BAD

[@TonyC2328]

Except Copper cools the CPU further by about 5 celsius, maybe it's not going to last 2 years, but still long enough until you upgrade CPU's anyway?

[@mortenwammen4159]

With Noctua heat sinks I have never had to reapply liquid metal (I use Coollaboratory Liquid Metal Pro). I am on my third system with Intel CPU and Noctua heat sink, I have never reapplied, my current system is a delidded Intel I7-7700K, no temperature problems, I could not swear, since my use changes, various overhead from OS and so on, but I have not seen temperatures change to any degree that I have ever noticed. For me the main attraction with liquid metal is pure laziness, I never ever want to touch that CPU again, and my fiendish, nay even devilish plans are proceeding as ...planned, so far. Honestly I thought this was the main attraction for liquid metal, the, what 1-3 degrees? difference, from properly applied liquid metal, does not make up for the hassle of properly applying the liquid metal, instead of fingerpainting on some paste?!? (Woo, the quitest fan in my case might ramp 20-40 RPMs up from what it is, Woo, bugga buggah, soo scary?)

[@Nedrozak]

I have a Sapphire Nitro R9 390 and I am thinking about changing the thermal paste with Conductonaut because the temperature is higher than my liking. The first year and a half it maxed out at 72C but lately I am racing for the over 80's. Can you give me some tips about doing it?

[@Nedrozak]

I guess I can do that. I think it is getting warmer not of age of the chip itself but the age of the thermal paste.

[@HexDan]

will i be able to use liquid metal on my Cooler Master Hyper 212X? it has aluminum on the base, but the actually pipes that make contact with the IHS are pure copper.

[@CarlosDeBernardMrAgapi]

It will be great to find out how pure is the copper plate. copper will stain and more when is expose on fast changes of temperatures. I will check my delid soon and see how that changes here.

[@sidewinder666666]

Good info, as usual. I knew that Aluminum was a no-no with any liquid metal, but wasn't sure about bare Copper. Now I know. ;)

[@jace_Henderson]

The first time he actually had liquid metal as a sponsor and mentioned Gallium I was like, “um, doesn’t Gallium weaken and eat away other metals?” Turns out my suspicion is justified.

[@CoalitionGaming]

I applied conductonaut to my EVGA GTX 970 FTW+, but discovered a few months later that it dried up (alloyed?) And was causing overheating issues. It was so difficult to remove from the coldplate of the cooler that I had to lap it off. No idea what happened other than coming to the conclusion that it must have been a low quality copper alloy of some type, or I needed to keep cleaning and reapplying it until the surface "stabilized" or something. Hard to say. Did a vid on it too, but it was pretty interesting what happened.

[@infernaldaedra]

Waiting for this one for a long time!

Conclusion: Just don't buy unless you're rich enough that buying an AIO every year does not affect you

[@aumomuat1]

3 CPUs (2 de-lidded), 4 GPUs, 3 laptops CPU+GPU (1 Lenovo IdeaPad SLI), 1 PS4 Pro, 1 Xbox one X, and 1 Nintendo Switch. after finding the drying effect is only a matter of time but will happen, possible pitting and definite staining liquid metal is not worth it.

[@davidgunther8428]

A minimum eutectic should have a fixed composition, so the mixture shouldn't be too much of a mystery. Sounds like they move a little away from the eutectic point to improve cost or performance.

[@peterkiss1204]

Moving away from the exact eutectic point to gain some thermal conductance isn't really a problem if the melting point is still under (or around) room temperature.

[@scooter4196]

[@GregorysBrain]

[@andrecostin1288]

It's fine on IHS and some tin plated heatsink. I didn't like the result with my Noctua though. Results may vary. IMO heatsinks can last forever. Why damage them...

[@tullgutten]

Just look at TheBackyardScientist at KZbin and his video on Gallium then you see the effect of it on Aluminium. If you take a few drops on a car rim that have exposed metal, within a few hours the wheel WILL break and fall apart just from standing still!!!! And since it destroys the protective layer on Aluminium it also makes it react fast with water making hydrogen gas that could ignite and cause an explosion or fire

[@ericdeltoro8484]

Super informative! I have a Clevo P750TM1-G laptop with an all copper heatsink, a 8700k that's delidded and using a rockit cool IHS and a 1070 that has direct contact with the copper heatsink. I was concerned about the potential degredation over time but if its just staining, I'm not concerned. Over the six and a bit month period, I haven't observed any drop in thermal performance but I did notice that the liquid metal looked kinda grainy, which made me feel like something bad was happening but after seeing this, it isn't too much of a concern. Maybe its just drying out faster in my laptop since the heatsink's cooling performance is basically maxed out at this point.

[@JustOneGuy]

you'll use up liquid metal a lot faster in a laptop than on desktop, in my g750jz the liquid metal started going "bad" after similar time than a thermal paste so in the long run it was not worth it

[@ericdeltoro8484]

As true as that may be, considering the hardware and the amount of heat it chucks out, especially during intense gaming sessions, I'd rather spend the extra time and money of replacing liquid metal more often than being thermal throttled or risking ruining the hardware sooner than I'd like. My laptop basically uses desktop parts in a much smaller form factor so cooling is especially important in my case. I'm actually working on a better cooling pad by using a pair of industrial Noctua NF-A14s for intake and another pair, one for each exhaust plus some ducting. I don't think the exhaust fans would do too much but after watching Linus' video of adding blowmatrons to a gaming laptop's exhaust fans, it did show an improvement in temperature. Blowies are WAY too loud for me but Noctua industirals aren't and they still give a lot of airflow at high pressures and in a laptop, the higher pressure would be very much appreciated. When I'm on the go, I pin the gpu to 1500mhz on the core, leave the memory at stock speeds, and downclock the i7 to 3.7Ghz on all cores with a 130mA undervolt (which I use when runnig at 4.4Ghz on all cores as well) then further pull it back to 55% with windows power management and I get a whole wopping 2 hours of gameplay on it, which again considering the hardware and the amount of power it uses and the small battery, that's pretty impressive. Thermals are also much improved to the point I can let the computer manage the fans rather than me setting them to 100%.

[@daryladams494]

so i could use a liquid metal like thermal grizzly conductonaut with a ryzen 7 3700x with a noctua NH-U12s ? also is it worth it?

[@Sareth94]

Wondering the same. Thinking about liquid-metalling my NH-D15 to a 3800X. It it drops temps and thus fan-noise I think it'd be worth it - but the application kinda scares me.

[@ktasuja]

I've just moved my laptop back to normal TIM and actually got better thermal performance for the moment. A fresh liquid metal application would still be significantly superior, but an interesting comparison to your degradation test results.
