my humor is so dark, i cant make a joke here.

I have a quick question and I can’t seem to find a straight answer to I have a 360 Corsair aio will it hurt to run it a 100 percent pump speed at all times ?

@@lonewolfrcs1331 I have my ek 360 running 100% all times and it's fine

@@lonewolfrcs1331 why're you trying to run 100% all the time?

Lmao Spot on!

Exactly was thinking the same thing 😄👍

More than likely.

I think Jay is starting to lose his mind tbh

The main point was to show how prominent they are compared to your typical thermal paste, normal thermal paste will show veins nowhere near to the degree this one did

​@@fabiokinolli You're not wrong about the veins being more prominent because of the grease being thinner but I don't think that was the main point he was trying to make. He mentioned that he thinks they show up based on high/low spots but I believe it's purely due to suction/vacuum force when removing.

I wonder if delidding and baking it onto the lid would work ? You would probably want to leave it a little tacky.

I guess on paper it has a better conductivity, but only in the right use case which this is not. A CPU us not supposed to get as to the point where this paste is supposed to be operated at. Maybe it would be good for some MOSFETs but little more. That's a nope for computer application.

@@timhartherz5652 True, but also at least it'll be non-conductive at Intel-spec in anything they made the past decade. Or Apple spec from anything in the past 20 years.

@@kloroformd "Within specs" for these companies mean "will survive the mandatory warranty period" :-D

@@timhartherz5652 if not, they'll polish a used item for ya. There's probably an arbitration clause embedded in the firmware for those that want to argue.

Is it really Watts per meter Kelvin? As an engineer, when I see units written like that my brain goes milli-Kelvin.

The devil is in the details. The problem is that the material with the headline conductivity (be it silver, graphene, or Boron Nitride) is usually only ONE of the ingredients making up the paste. The ratio of high conductivity material to the carrier matrix makes it a lottery whether the compound will be good or bad at heat transfer. For example, a TIM with 1% silver and 99% insulating mush will be next to useless, where something with 99% silver and 1% mush will be almost as conductive as pure silver. Kinda obvious and intuitive, but finding out the % ingredients in any TIM is next to impossible, because they are "closely guarded trade secrets". Field testing to determine what works and what does not, is the only way to sort wheat from chaff. And we have to ignore the headline conductivity of the buzz-making ingredient because it gets swamped by all the other stuff going on. The burger analogy (with all the layers) further subdivides within the paste layer, where heat is mostly moving through the "solvent" (the material that glues all the particles together) but can use the high conductivity particles to "short circuit" across the higher resistance matrix. Again, the percentage of high conductivity material greatly influences the conductivity of the composite, including whether the particles of the high conductivity material actually touch each other (allowing a more continuous path of highly conductive material through the compound). It is never that simple, though, with factors like surface roughness of the particles (and even whether the particle surface has oxidised, adding a layer of resistance to the surface, etc) all affecting the score. The only effective way to measure whether the TIM works, is a real-life test like this one. Good developers will experiment with their product ingredients to find an "optimal" composition. Which may or may not include a necessary process of installation (like "cooking" the Boron Nitride paste before it works properly). Graphene is an outlier here, since it is "pure carbon". But it equally misleads, because the very high conductivity of a graphene sheet is ONLY "in the plane of the graphene". Unlike most materials which offer the same value of conductivity in all directions, graphene is extremely directional - because a graphene sheet is only one atom thick. What is marketed as "graphene" is actually a very thick stack of multiple graphene sheets to form a paper. When multiple layers of graphene are stacked together to make a TIM, then heat has to travel from layer to layer, and the conductivity of that assembly is very much less than the in-plane number (I'd estimate only about 10% of the in-plane value). So why does graphene paper work well as as TIM? Because, heat enters from the heat spreader at a few very local hot spots. The graphene can then spread that heat about the in-plane area extremely well, using that high conductivity. The less effective layer-to-layer transfer is then mitigated, because it can use ALL of the contact area for that transfer. With most (non-directional conductivity) TIMs, there is no diffusion of heat within the layer - heat spreads from the source hotspot in a spherical manner, which barely increases the area of transfer at all, before the heat is already passed through the thickness into the cooler.

@@mastersprite2783 Lol. Yeah, you're technically right about "mK". The definitive proof otherwise is that if you do Dimensional Analysis of what the number is made up of, you get "heat energy per unit of distance per degree of temperature". If it was indeed milliKelvin, then the distance unit would be missing.

@@bythelee actually it's not how graphene thermal pad is made, at least not Kryosheet from derbauer. He explained it in one of the video. The graphene sheets are stacked and baked together into a thick block and then it's sliced from the sides into a thin sheets, so the graphene planes are actually perpendicular to the surface of cooler coldplate and CPU.

RTFM Jay, not long enough with nowhere for the water to go. This isn't as bad, but don't be Linus with Billet Labs because of impatience and not wanting to go through the hassle.

Not to mention that, IMO, he put WAY too much on the CPU. The best conductivity would be metal to metal, but since the metals aren't perfectly smooth, there are, as Jay noted, "voids" and non-contact points (due to the CPU/cooler not being perfectly flat) and there needs to be a minimal conductive paste bridging those gaps. As you noted, water isn't the best temperature conductor (only 0.6089 w/mK - Wikipedia), so it would need to be evaporated before the thermal paste would perform its best. So, yeah, I'd like to see this test repeated. Especially, since it doesn't seem to be being used in an optimum manner in this test. Anyway, my "$.02"...

@@Revan_7even Good news is he's not naming companies. This is an example of how preconceived bias can result in a flawed test. In this case it's a reasonable, "The product was not designed for this application."

*Oh, yes. Your story has the familiar defense electronics vibe, including the always-present OSHA rep. Mostly degree-flexing, annoying and intrusive, but priceless in this instance. Echoes of finding the ways to mill Beryllium MMW TWT cavities without killing the machinists in the process. Respect!*

perfect for AM4 CPUs it seems :P

5 minutes test at 90C is not nearly enough to cure it. Not a representative test. Edit: It wasn't used in design specs :/

@@IcecalGamer It dries naturally over time. Not that the IHS sits at 90C when the CPU is at such temperature, you need ZERO cooling for the IHS to reach this temperature. Else it's impossible to even come close to 70C.

@Timmy_420 Do you realise, that the iGPU is in the silicon die, that also houses main cores? You'd be at >constant< 80+C with an IHS of 60C.

what no it doesn't it's not an epoxy. I use this stuff all the time on 3d printers at 220c+ everything separates easily. I think you may be thinking of a thermal epoxy.

more like a knook

Not a kitchen

@@Rockr69747 nook?

If you do that then you will get voids as the paste shrinks. The spec is usually one or two mils

That is what I always thought but I had problems with Thermagic ZF-12 because of how thin it was. It works fine at first but then it squishes to the sides and temps start to get awful again.

@@hmello3250 there is a happy medium. If the paste is very thin then it runs out of the areas that it's supposed to be filling. Essentially leaving airspace in between the two surfaces. I guess I've just never run into one that's that thin.

​@@shanent5793 any proof of this? I've never heard of this, or any effects from this, if it happens. The guy you're responding to is right with some of what he is saying. You want to remove the air, using the thermal paste. So more is better (unless it's conductive). . Also, application is cold / room temp. From there it gets warm and it's viscosity increases, so the volume expants . Even when that contracts, I don't see it creating voids, it's not "slime" or playdoh.

@@zadekeys2194 I think it's common knowledge that thermal paste dries out and has to be replaced periodically. This is done because the oil component of the thermal paste evaporates, leaving behind grains of filler that have only point contact with each other and is thus a less efficient thermal conductor. So even if you managed to machine the surfaces of the heat spreader and cooler optically flat, and you put the perfect amount of paste so that all the points that can touch, do touch, and the paste only fills in the remaining voids-soon enough some of that oil will evaporate and it will no longer be the perfect amount. By putting more than the minimal amount it allows some reserve capacity between refreshes. There is a trade off between getting the lowest possible thermal resistance and a longer service life. Putting more paste increases the resistance but there will be more time until it has to be replaced. You can put less if you accept having to replace it more often. The specification of one or two mils (0.02-0.05 mm) is usually given by electronic component and thermal solution vendors

As others have noted, the temperature it's tested at is a key factor. Given this is designed for 3D printing, it was likely tested at 200+C. So, twice the temp!

I have been thinking about trying out the kryosheet myself...I'm using direct die with liquid metal right now, but it is very annoying to clean up...Plus I have to basicly lap my cold plate everytime because the liquid metal kinda etches the coldplate...I have heard the the kryosheet works almost as well as liquid metal and I won't have to worry about it anymore! I may throw one on my GPU as well...

@@brucepreston3927 I don't think the Kryosheet works nearly as well as liquid metal in most benchmarks I've seen, but I don't think I've seen anyone trying it direct die either. That said, how often are you re-opening and re-applying LM? It should basically be a one and done job, it degrades maybe a couple C over years.

I've never used liquid metal, so I can't speak to whether or not it is better than the Kryosheet, but I have been using the Kryosheet since it has come out, and it works very well.

@@tmoore121 My PC gets very dirty where I live so I usually do a full teardown and deep clean twice a year...I know I don't need to change the LM every time, but I do it just for piece of mind and because I might as well if i'm already doing a full teardown of everything else...I will pick up a couple kryosheets just to try it and see what temps I get...I know it won't be as good as LM, but if it's pretty close I may just keep using it...I'm sure it will work better on my GPU also, I haven't been brave enough to try LM on that...

@@TTM1895 Thats good to hear! I know it won't be quite as good as LM, but it will fun just to test it and see what I get...If it works well in my PC, I may try it on my laptop also...I just like tearing computers apart! lol

the pure silver stuff works very well.

very good. someone got the point. the application is more important than the material itself. conductivity is not "linear". the 13.2 vs 12.5 conductivity won't have any effect. Even beyond 20 W/mK is not something spectacular. This is a UNIT of measurement. Not a guide. Watts per meter Kelvin. written wrong from the beginning ... Joule was like "am i a joke to you?"

Yeah, no. If I want to game, I don’t want my parents around. As a parent you give them space and especially once they’re in their teenage years and going into adults too.

@@duskshadow25 Hard disagree. His youngest is like 9. Some supervision when gaming online at that age is a good thing. I say that as someone who was playing GTA Vice City unsupervised when it came out at age 5.

@@duskshadow25well that sounds like you’re obviously doing or saying something you shouldn’t and don’t want your parents to know

It's more like bring your kid to work week. Probably spring break for them. 😮

@@RubyRoks I'm not talking about kids age. I'm talking about teenage, hence why I said "teenage years" in the original comment. If you have a child let's say 13 or under, then yeah, I would be paying a bit more attention on the games they're playing. But if they're in high school already, I would generally leave them along and try not to pry into their lives unless they approach you for advise specifically. When I went through high school as a teenager, I personally didn't like people budging into my own business. There's a thing call space and privacy, and it's one of those things I give people because I wouldn't want others to keep invading my own space and privacy. It has nothing to do about hiding something, but it has to do with letting your kids go and letting them grow and giving that room for them to decide what they want to do. And whatever they decide on, they need to understand there's a consequence to their actions. That's why I talk to them, instead of just pushing my own perspective onto them, as they get older. When your children are young, as in pre-teenage year, you can pay a bit more attention and deicide for them if they're struggling, but it's not like you can't communicate with them. I would still speak to them ask what they want to do, just like how you would communicate in your marriage. I personally don't think there's only one way to do something. Just like 1+1=2, 4-2=2 & 4/2=2 as well and so on. That's why you communicate. The the whole point of parenting isn't to force your perspective onto them but it's to give them the time and space to think for themselves. If they fall, don't pick them up (obviously talking about they can think for themselves already and not as a baby that can't even walk yet). Let themselves get up and figure it out. If they cry, that's fine. But it's gonna be okay and they'll move forward, because the sun will still rise and set tomorrow. Set them up for reality and success, not over shelter them with your own views. Because if you're overprotective of your kids and control everything they do, you're only going to push them away further. Something I can tell you is that, my parents were religious growing up. The praying never made sense to me growing up. But they gave me the freedom to choose what I wanted to do and decide my own path instead of them pushing their religious view onto me. I'm not a religious person like they are, but I still have good relationship with my parents because it's perfectly okay to disagree on something and still coexist. So many times I see parents force their views onto their kids and force them to believe in something just because that's way they believe or were raised to be. And people just blindly follow it and accept those beliefs without questioning or figuring out if it's actually right for themselves.

IIRC, there is an interview with Der8auer where he calls the thermal conductivity ratings are junk. That they can engineer and game the number to what ever they want and it will have no noticeable benefit in real world testing.

Engine oil does a great job in a car as one of the three jobs it does, plenty of viscosity there.

And I mean actual thermal pastes, not things that aren’t, like peanut butter haha
