So, it's just far easier to use a graphene sheet.

You can apply them bad in so many ways. 1. Touch them will destroy the anisotropic property of the sheet. 3. The more often you reuse them the more the thermal conductivity shrinks. Because every time you apply the sheet and compress it, it degrades.

there are varying qualities, but generallt the thinner ones work better. they dont bend or twist well so its nice to get it close to the space available, and know how much of a gap is left between the cpu and the heatsink. youd still need something to fill the gaps, its not soft, and doesnt fill those gaps... but you dont need so much... since its harder than the silver it should press through and still make contact. i really wish i can get some legit graphene and try some stuff... i usually leave the old stuff on there and burn it in... if it starts crumbling mix it into the new paste. in theory you can do the same with the graphere as it falls apart... just you have to keep in mind its nanoparticles... if the pad ever breaks up on you. best vacume that thing out... pretty much the only downside is how fragile it is.

Can confirm. I've got several IC Graphite brand graphene pads on numerous different systems that I've been running for 5+ years without any issues. I've swapped coolers on a few of them, had a mobo failure on one and swapped it out used the same pad, cooler, and CPU, no problems at all. Heck the system I'm using right now to write this has an old 3950x with a graphene pad and a Noctua nh-u12s (to fit in the rack beside my desk) and have had no problems with longevity or temps. Did my own tests years ago and found them to be on par (within margin of error) of most thermal pastes I was using at the time. The best part really is when something happens and you have to remove it you're not stuck trying to pry the cooler off the CPU without damaging anything, no mess- no fuss. I am honestly surprised to see you so late to join the party on this one. A number of other channels also came to similar conclusions years ago when they came out. There are plenty of stories of people reusing the same pad 30+ times on test benches.

On the cost budgeting/value side. I normally buy at least 2 uses worth of thermal paste, because I dont build PCs very often, I need the option to retry if the first application is crappy. The graphine pad can already be reused so I'd be confident buying it once. So that boosts its value too.

For my purposes I do not mind the extra cost for this convenience and cleanliness. I do agree that depending on your reason for the build/rebuild it may not be as cost effective as thermal paste. But for me it is worth it.

[@markhackett2302]

Graphene pads work as well, within "no discernable difference" from a decent high quality paste, it is reusable, but more expensive. If you don't reuse it, you wasted money. If you spent 20 minutes cleaning paste residue, then it kinda depends on what that time stopped you from doing, so for "professionals" testing CPUs, just that alone would be much of the extra money, even if not reused. But as an end user, it's benefit is mostly reusing it. That means the old CPU/socket needs to go to someone who either gets a paste solution (for example, a hand-me-down) or you sold it without on, for example, eBay, because otherwise this pad goes with the CPU, so it is not going to be reused.

[@GingerBeardicus]

As an end-user, this seems really useful. Yes, it's more expensive than a 1 gram thermal paste tube but the appeal of "apply once and forget" is definitely there, especially if it's on par with one of, if not the top performing thermal paste on the market. The conductive part is a little worrisome but as long as there is no contact with any motherboard components or traces, it should be fine. I do wonder, can we see a GPU video with this pad in the future? Whether it's with the stock air cooler or a watercooling block is up to you of course!

[@Reirainsong]

One thing that minimizes the risk of conductivity is covering up the entire CPU except the top of the heat spreader with a contact frame replacing the default locking bracket. Thermal Grizzly also makes these, but their design is too dependent on correct screw torque, Thermalright bracket is cheaper and better in practice. It's meant to prevent the problem of 12/13th gen Intel bending under tightly screwed coolers, but the side benefit of protecting socket from thermal paste spillover was notable enough that they made an AMD version too.

I would really like to see how cleanly the graphene sheets can be cut. Given that the material is conductive, do you have to worry about a "frayed" edge that might drop conductive dust into your system? I would also like to see how fragile the sheets are. Would the average PC builder need to be extra gentle with the graphene sheet to avoid destroying it or can the sheet withstand a bit of bending?

Keeps it cooler than stock, but the big win comes with no more paste pump out! lol Thinking about getting one for my 5800X3D, but it stays pretty cool as it is. After the 2nd failed mount, with the pad moving, I decided the third time around to use a 4 tiny tiny dots of thermal past at the very edge at the corners of the pad, which kept it in place while mounting.

I've used these, as well as the IC graphite pads, for a while for cooling. In my experience they are indeed very sensitive to pressure. I don't a have a proper "high performance" test or comparison but the performance was good at that end and quite poor at the low end. Also I found that they are very fragile. They easily tear so you need to be very carefull taking them off especially when you have pieces overhanging. Also at the cooler side, for example the intel stock coolers (especially the older ones with a cylindrical copper slug) were very damaging to them. The kryosheets were more fragile than the IC pads by the way, the IC pad I still have is still kinda square while the kryosheet has more of a Texas shape now

[@bellotriggerfish]

I'm using the IC Diamond Graphite pad. Have reused it now 5 times, and still solid performance. They are cheaper than the Kryosheet, too. I would not want to go back to thermal paste just to gain maybe 1-3 degrees C in temperature. These pads are so convenient. Also, no tear so far on this pad. Best purchase I ever made. (oh and the cooler is a massive NH-D15, so lots of weight and pressure). Current CPU is a 5800X, but I had this for my previous chip which was a 3600X.

@@lurch789 You are wrong. The best paste, newly applied will be better, but it doesn't take much of a drop in quality of paste to get lower than a graphene pad. And not much in the way of drying out for a high quality paste to be worse than a graphene pad. The best use case for paste is high quality paste often reapplied, but that is also the best use case for graphene pads. In general, there is no difference between a good paste and these pads of graphene. If you hardly ever use them, it is 20 dollars you didn't need to spend, because for 2-3 years you might not need another 5$ tube, but "on average" over that time, the pad would have been better, just nowhere near where you should care about it. The major use of it is if you test CPUs. You get a lot of cost with a new coat of grease, and the hourly cost to remove the paste enough to fit some more paste is vast, compared to the cost of the paste. But if you use a pad, then you get a pair of tweezers and just remove then replace the CPU and put the pad back, and you should get the same cooling in either case. Test 20 CPUs and 1 pad is needed, and no cleaning time. You may need to replace after scores of changes, mind, it is only graphene after all. About the only case it might not work for is LN2 cooling, but you don't use paste either.

Any amount of rubbing, even with something super soft, is going to micro-resurface both contacts to some degree. 3. Sides of the lid get hot. In the graphene case, the thermal compound left on the sides have a different thermal transference pathway to the cooling block surface (than mere air).

I switch back to thermal paste and won't even consider using a kryosheet again. It looked great as a concept, which is why I bought it in the first place...problem is it doesn't work as advertised over long term usage.

[@05Matz]

Most graphite pads would be aligned with the graphene layers 'stacked' like a box of paper. This would be great at spreading heat side-to-side, but mediocre at transferring heat in the Z-direction. These are apparently unique in that they're aligned edge-on, which makes them even more fragile but should make the heat transfer _through_ the sheet (into the cooler) much quicker. However, this would give them a 'grain', with one direction 'across' the sheet fast-transfering and the other slower. I wonder if that means there's an optimal rotation for certain CPUs (I'm especially thinking of the higher-end X3D AMD CPUs, with one high-clocked and one 3D cache stacked (more heat-sensitive, lower-clocked) set of cores. Would you want to arrange them so that heat transfer BETWEEN the chiplets is slower than heat transfer ACROSS and 'UP'?

Hey Jay, I know you're smarter than me but having experience with this substance, it is very beneficial to trim it down as it will cool better. If its hanging over, it will not put all the heat it draws out of the CPU into the cooler. I know that sounds strange, but that stuff works soooooo well, that its very picky about how it performs. Plus it can tear off and drop down and touch something electrical, and then shorts start happening. Fun fact, my kids like to take a piece of it and let it take the heat out of their fingers and cut through an ice cube with it. Come-on their kids. Fun Fact 2: If you cool a GPU with this stuff, only do it with water cooling as an air cooler will actually heat up the GPU, why? because it works sooooo good, that it will take the heat from the memory on the card and some of the heat will flow into the GPU instead of the cooler, but a water block will work fine and give you about 10-12C cooler. Enjoy!!!

The excuse of thermal paste being messy is because of over application. As you said the surface of the cpu lid and cooler block have "microscopic irregularities" You only need to apply a thin layer of paste. Obviously having metal to metal is ideal heat transfer. I know the debates of how much to put on has been covered. Any build up of unnecessary paste is a heat block, especially if its squished out the sides and gathers into the nooks. That is not an acceptable. every surface counts. I like the thin sheets, that's how thin the paste should be.

Jay, the science behind the whole "cooling grain" as you called it has to do with the physical molecular arrangement of graphene. Graphene is an _amazing_ thermal interface, but it hasn't really found any use in commodity cooling solutions before now due to the fact that graphene has its molecules hooked up in long, 2d horizontal chains, which dissipate heat extremely well...on the X and Y axes. However, as you can probably guess, for CPUs and the like, we need to be moving heat _upwards_, in the Z-axis, away from the IHS and into the CPU cooler's coldplate. The way that Thermal Grizzly Kryosheet gets around this is by stacking tons of sheets of graphene on top of one another, and then cutting them such that the molecular chains end up pointing upwards. So each of those Kryosheets you showed in this video is actually several, dozens or maybe hundreds, of graphene sheets which have all been sliced into ribbons a few microns thick, then pressed together into what looks like a single homogenous graphene sheet or pad. Hope this helps! You can learn more about the technical specifics behind it by watching the video Gamers Nexus did with der8auer where they stole Asus's conference room at Computex for 40 minutes for their annual nerdy bro-out. Hope this helps!

The reason, why most materials have isotropic (in all directions the same) thermal conductivity, is firstly because their atomistic, molecular and/or microscopic parts are randomly orientated and secondly, because those parts are so small compared to the usual objects made from the material, that there are so many of them in any direction, that the randomness cancels out any anisotropic properties, those small parts might have. - E.g. gasses and liquids consist of atoms or molecules with random orientation - Dispersions like milk, most paints and thermal pastes, consist of particles, that are suspended in some liquids. Those particles also have random orientations. Often the particles can have a random inner structure as well. - Glasses consist of atoms, that might have some near order (orientation with its next neighbor atoms). But after a certain distance, the orientation randomly changes. One atom has a size of 0.1 nm (10^-10 m or 0.0000000001 m), so even if the orientation would only change every 10000 atoms, that would mean a random orientation change, every 1 µm (0.001 mm). But usually it changes more often. - Most metals consist of small grains of metal, that are randomly stuck together. The grains themselves can have internal order or disorder. - Polycrystalline materials consist of small grains of monocrystals, usually randomly stuck together. To have anisotropic thermal conductivity, you need a material, where it's microscopic components are ordered in a certain direction, over macroscopic distances. E.g. if you want order over 1 mm, you would need to line up around 10 Mio atoms perfectly in every direction, meaning around (10 Mio)^3 = 10^21 = 1,000,000,000,000,000,000,000 atoms in total. For gasses, liquids, dispersions and pastes, that is usually impossible. Thus microscopic order up to a macroscopic scale, is usually only found in solids. - Monocrystalline solids are the prime example. In those, the atoms are ordered. This could e.g. be in a simple cubic orientation, like this: ... ...aaaaaa... ...aaaaaa... ...aaaaaa... ...aaaaaa... ... In such an orientation, it is plausible, that the thermal conductivity (propagation of vibrations of atoms in a certain direction, similar to sound), depends on the direction. E.g. the thermal conductivity along and diagonal to the cubic order, could be different. - Ordered polycrystals are another example. In those, the microscopic monocrystals are all oriented in the same direction. Then the heat conductivity in that direction, could be higher, than in the other direction and the shape and size of the polycrystals could be used to enhance it to. In other words, you can use several degrees of order to optimize the head conductivity in a certain direction. You e.g. could create a thin plate of long monocrystals, with a certain internal structure, that are all ordered through the plate. If the material, orientations and dimensions are chosen right, you can achieve very high heat conductivity through the plate. This was e.g. don with diamond. - Graphite is another example of a material, that can be monocrystalline and graphene are some layers of that crystal structure, that can be produced separately. You can weave them into certain orientations, achieving high thermal conductivity in a certain direction. 21:12 - "... phase change ones, that have a finite life to them, still and can potentially dry out, because they are liquid based." That is not entirely right. Phase change cooling pads consist out of a metal alloy, that is optimized to melt at a temperature slightly above room temperature and then flow into the gaps of the rough metal surfaces. For such metal alloys, vapor pressure is incredibly low, meaning there is no significant evaporation. Thus from that standpoint, their lifetime should be much higher than some liquid based thermal pastes. However some of those metals can react with the metals of cpu and cooler, causing some forms of corrosion, that might lead to problems. - For thermal pastes, one could also liquids, that have very low vapor pressure, like certain oils, that practically would make them last indefinitely. But those might worsen the thermal properties of the paste. - Regarding the graphenes long term durability: It might last long, but I wouldn't take that at face value. Graphene is a mono atomic sheet of carbon atoms. So it is incredibly thin and fragile and might get damaged over time. Be it mechanically (vibrations, thermal expansion, changing the pad, ...), thermally (many temperature changes) or chemically (oxidation with the oxygen contained in air). So to determine the long term durability, long term tests would be needed. - In other words: Something drying out, is not the only way something can degrade. Mechanical, thermal and chemical processes can also degrade materials.

I think when you posted this video, I somehow missed it. I I wish I caught it because I just replaced my thermal paste we're on the same time you posted this video. Except mine was a nightmare. I'm in a prep class for c++certification. I've been doing my own stunts with computers for almost 15 years. That means building them too. I'm constantly learning. Thermal paste is kind of my weak point. I don't practice enough to get it right. So when I did my thermal paste on my AMD 3600 I put too much on. When I went to replace it this year, my CPU came out with the block. In the process of trying to pull it off by hand, I bent my pins. Thankfully my teacher gave me the right advice and I was able to get it off and fix my pins. I heated it up with a hair dryer and as I was trying to remove a screw from the water block because it still didn't come off, it pushed up against the CPU and it just fell right off. This thing would have prevented something like that for me. I kind of want to replace my thermal paste again with this stuff. Question though. Does it work for GPUs? I imagine there you need to cut down to size.

This thingy is grate for service shops... been using it for a while and there is no mess when u need to reapply it. When your done with pc service just put normal thermal paste and ur good to go. Its a bit pricey, but in a long run its much cheaper because u can use it multiple times and there is no cleaning after every use, so it saves time and money :)

So, the axial thing is because of the material being used. Graphene is a weird/cool material science molecule, which gives it unusual properties. More specifically, it's a functionally flat sheet of carbon atoms laid out in a mesh - think of it as super thin, super strong paper. Put 2 pieces of graphene together, and they're going to have very different properties between the 2 pieces than sideways within a single sheet - much like how 2 pieces of paper will have very different interactions from 2 parts of the same sheet of paper. One of the things that happens really well within the sheet of graphene is conductivity, both electrical and thermal. Therefore the graphene will conduct heat and electricity sideways but not up or down (if it is oriented to lie flat on a desk). If this were what these sheets are, that would be extremely bad - you'd have an extremely strong layer of insulator between the CPU and cooler. So they just turn it on its side, layer a bunch together, and cut very thin slices of it. So that's not one sheet of graphene lying flat on the CPU, that's a BUNCH of very small sheets sitting upright like hairs. (That's also why you can tear or cut it; if you're trying to cut through graphene itself, you're probably gonna have a bad time if you're just using scissors.) Therefore, the line of high thermal conductivity is from CPU to cooler, and thus you get quite a lot of heat transfer. (At least, that's the theory. The results, well, real world data tells the story there, so watch the video if you haven't yet!)

Saw this vid when it came out. My PC was being RMA'd at that time, saw the shop had these in stock and thought why not. I just got the PC back and the people from the shop told me that this worked so well that some of them who worked on my PC are now considering switching over :)

[@Rad_Pug]

If you are thinking about eventually selling parts. The pad is a good way to go.

[@TheDacane]

The "grain of cooling" is actually a grain to the graphene sheets. They are generally laid flat, running the direction of the sheet for strength. Heat transfers best along those fibers, rather than between them. In our use this would help disperse heat left to right, but not be as efficient moving from cpu to cooler. These pads have the grains running from top to bottom, this makes them much more fragile but means that heat transfers alone the carbon tubes to the heatsink. edit: if it helps you can imagine them as little liquid cooling tubes, just laying a stack of tubes on their side between your cpu and cooler wouldnt help transfer heat nearly as well as actually running the tube from your cpu to cooler

[@Dwight.Schrute69]

These pads are sturdy and reusable. I have been using one on my daughter's PC for a couple of years with no issues. I have touched it and it's never torn or fallen apart. I get being cautious, but Jay is taking it to an extreme.

[@Leviathan3DPrinting]

The cooling is directional because the more you squeeze it the closer the layers of the graphite. Normally a thermal compound is homogenous and has no direction but this is a foam layered with graphite. IC diamond makes a similar product with a wonderful graphic of what happens to the pas under compression both on their packaging and under a microscope. These types of pads are also extremely resilient to damage and can easily be cut to size with scissors though I'd imagine finger oils aren't good for thermal transfer. Wonderful for permanent installation where zero maintenance is required. They should easily outlive whatever product you install them onto. Great video!

[@brandonupchurch7628]

No this is completely different the IC Diamond pad and Thermal Grizzly Carbonaut are graphite foam, this is graphene, it's a bunch of sheets of graphene that have been extruded on one another, normally the problem with graphine is that it conducts heat well along the length of the sheet, but with this they have layered the sheets and then cut across so that the conductive axis is the short height of the pad.

A good practical application is computer repair shops needing to repeatedly insert test CPUS to update BIOS for older motherboards with no flashback button. Takes the worry out of potentially overheating CPUs during flashing and not needing to replace thermal paste frequently.

[@shaolindreams]

Drying out over time is actually a big problem for systems dying over time... usually when some technician repairs a system most the time they can get it running good again with a clean and new paste.... So for systems that people are going to use maybe for a long time and aren[t going to access the CPU... i think that's a great feature of these pads, providing they last that long.

[@LethargicSquirrel]

As a first-time user of these with a 14-700K build... I'm really glad I got this, considering all the CPU-swapping I've been doing, thanks to Intel's incompetence with the 13th and 14th gen CPUs. Did a bunch of troubleshooting which included multiple swaps of CPUs, so this was a great time-, effort-, and cost-saver. That said, I would've REALLY liked to see you test a CLEAN processor. It takes so little effort to remove and clean the extra paste residue off, and the entire point of the video is TEMPERATURES, so I'm *really* disappointed you didn't take the time to do that. Would it make a BIG difference to the end temperatures? Probably not, but even 1° or 2° would've still been nice to know about.

[@jasonT683]

I have been using this on my Gen 6 i7 for quite a few years at a 7% overclock. I don’t remember the brand that I used when I built this setup but I have reseated a couple times with no issues.

[@user-xf5uh2rh6b]

I’m sold. For me it’s just the application, not having to worry about not applying the paste correctly or having trapped air. This seems a bit easier. I found a graphite pad for $13.

[@RexasRed]

I will say a few things. I have an Omen 17 with a 165w Rtx 3080 and an Intel i9-11900h A month ago, I replaced what was in it with Arctic MX-4 on both the gpu and cpu. It was constant thermal throttling at 97c on the cpu and the gpu was steady 70c while running Palworld. I just put a 24*12 Thermal Grizzly Kryosheet on the die of the 11900h and thinly spread the Kryonaut extreme on the gpu die. Now, running Palworld, I'm getting the gpu at 60c and the cpu at 64c steady. I'm extremely impressed with both. I hope they remain this good.

[@JxPoe]

needed these when i was upgrading my old lady's cpu cooler to an AIO, cpu got pulled out with the stock cooler and it bent 4 pins. luckily got them straightened out and everything works fine now

[@MrGyyro]

I run these on my asrock 7900xtx aqua, due to the hotspot problems that card has. They have worked fantastic and can handle the heat with the card pulling close to 700 watts overclocked. 3120mhz core.
