 It feels like every time I come in this room, it's some crazy cooling experiment, usually with you. The aircon's good in here. Which is... And that actually probably makes sense because this room isn't big enough for us to actually hold meetings in here anymore. And because we're at it yet again, this right here is a bizarre cooling product. This is the IC Graphite Thermal Pad. The last thermal interface you will ever need. They claim that this thermal pad performs as well as thermal paste. It is extremely durable, so it could last for decades, and it's reusable. Let's investigate, shall we? After I tell you about private internet access, PIA is the VPN service that encrypts all of your internet traffic and uses a safe, protected IP. And it's got lots of other useful features as well. You can check it out at the link below. Ow! Well, it conducts heat. Yeah, really well, especially in the XY. All right. So what the hell is this thing? So, that's totally graphite, which I guess is carbon. But that thing like I said before is something you can go throughangrily and really fast when making thermal PC. Which of course is great when you're in the summer like today, but I'm pretty serious, that this thing is almost like real graphite cake. I don't know exactly what to say for that. What exactly is this? I have notes This is the innovation cooling graphite thermal pad the goal of it is to replace Traditional thermal pastes in long-term applications its main advantages are its easy application There's no guessing how much to put on its extremely long life And it's high resistance to thermal changes which make it also good for extreme cooling scenarios Where liquid metal or normal thermal paste might freeze? So in a nutshell what they're saying is that this pad? Even though it will be so thick compared to a paste has no real disadvantage compared to spreading goop on your CPU well one disadvantage is that it is electrically conductive so One yeah like two homes Which is like better than a wire, but if you just toss it on your motherboard. It's gonna fry it So okay, so you do have to be more careful, but unlike liquid metal. It's not gonna seep out Yeah, it's not gonna. Just go everywhere you can get it pretty on there So would you just cut it to size if you had something that was yeah, so the main spec on this is its thermal conductivity 35 watts per meter Kelvin, but I think probably most people wouldn't have a ton of context for what that means so compared to like IC diamond that's Really high so this is like four and a half watt per meter Kelvin So it should be able to conduct a lot of heat through it But what is a watt per meter Kelvin You don't know exactly do you know why do I even employ these people I'm looking it up right now Unfortunately, there are differing definitions for these terms Okay, so quantity of heat that passes in a unit time through a plate of particular area or thickness When opposite faces differ in temperature by 1 Kelvin So that means that if there's one Kelvin difference between the two You can conduct 35 watts per meter, so it actually makes a lot of sense when you think about it like that Cool, let's try it This is trippy man like Cleaning all of the paste off and having it just like dry mounted Like there are things in life that feel natural to mount dry and there are things And there are things that don't Uh-huh So an advantage to this dry approach is that there's no liquid Like you know most thermal compounds are some kind of a suspension of some sort So there's no liquid to eventually evaporate or dry out or mush out or anything like that It's just that's just it you just plunk it on there. This is crazy Just for the sake of you know transparency No thermal paste Double screw on the drive. Oh you finished first now. I feel awkward Okay It's trippy like it seems like it's not right you know So we're looking at this is a 7980 XE with liquid metal in it Okay, so we're looking at an average temperature across all cores of 50.56 and that was with IC diamond Yeah, so IC diamond might not be the highest performance thermal compound, but it's very respectable They're all within the same temperature range At the high end yeah, I mean we'd had that bulk stuff that didn't perform particularly well That video is worth watching you can check that out here. Nothing's immediately concerning. No That looks very impressive Yeah What did we get on IC diamond max 58 average 50.56 Like it should perform in everything that's on the IC diamond 58 average 50.56 like it should perform in everything that i've read one to two degrees worse but I mean that's part of the argument for a solution like this that there's no room for user error Yeah, like I might have done a bad core application or a bad mount. So at the end of the day, that's the conclusion of this video Alex is a bad mount We won't know for another 20 minutes or so or maybe five minutes, I don't know All right So it's been Hours 17. Yeah. Yeah. Okay. Cool. How'd we do? plus 50 plus What's the point of even having a fancy ass calculator if it doesn't get it right? Well, it's not the calculator's fault So it's the user Heatsinks barely warm, which I guess makes sense It still trips me out. So this one from alex's pre-testing has actually been used a couple times And innovation cooling told us that they've had people beta testing these that have reused them like over 20 times Over 50 even really over 50. Yeah over 50. All right, so our average is 51.7 So Exactly what we expected. Okay, so all that's left for me then is I want to I want to see like is it thinner yeah, I don't know like I guess let's shut her down. All right Oh one thing that is cool about it is that it has um The 35 watts per meter kelvin that's in the z direction. So like up and down But it's 800 Ish 800 000. They're not totally sure watts per meter kelvin from side to side Oh, so that's why it burned me when I torched it. Yeah, so that's really good If you have like a hot spot on your cpu, it'll Get it out to the heat pipes really well. One thing I don't like about it that much is the size Why well I mean that looks fine for a core i9 But if I was cooling something like a thread ripper or one of intel xeon scalables or something like that like a really big chip I kind of feel like you could actually have die area Can you just use potentially not covered I don't know. It's a wonderful question. I don't know the answer to that. So I guess it should be like that in Theoretically nothing would ever happen to it at all. Yeah, they said lifetime It should be about the same I think the coolest thing about this for me is like, you know for the last 10 20 years, you know every other month There's like a big article about how you know carbon nanotubes or this other novel implementation of carbon is going to completely revolutionize everything and Up until now at least in the thermal space, although theoretically it has great thermal properties.
