 For just $10, this tub of goop can give you more FPS. At least it can according to computer systems who made it. To put their claims to the test, we're gonna be removing the stock thermal pads from an X17 and a 3090, applying this goop and reassembling it all to see how much improvement we can get. Is it worth what I'm sure will be a huge mess? I don't know, but I am sure I want to tell you about our sponsor.

The first is someone realizes gamers have a lot of money and they want that money. And the second is someone has a use case in industry and they find out after the fact it's good for gamers. This fortunately is in the latter group. K5 Pro came about because the founders were just working at a computer repair shop. They're having a lot of issues with devices coming back to them. And they realized that a lot of the time, the problem were just old worn out thermal pads. A thermal pad is a specific thickness. Like this one right here is one millimeter. So they would have to go in, measure it. And if you get it wrong, your device overheats and it dies. Now it just so happens that they also were working at a university. So they did the thing you do when you work in a university. The result of all of their R and D is this right here, K5 Pro. It's a goop instead of a pad. So they can just slop it in. And apparently it's way more conductive than a thermal pad as well. And can have performance gains in like, you know, something like this right here. Our test today is pretty simple. First, we're going to just run them stock, find out, you know, baseline numbers. Then replace the thermal paste with thermal grizzly cryo knot. From there, we're going to tear it apart again, replace the thermal pads with K5 Pro and cryo knot to find out basically the maximum performance of these things with their current coolers. We're going to use Furmark, F1 2020 and 3DMark to hopefully give us a good range of stuff. And I'm going to go eat some lunch and see you in 15 minutes. First round of tests are nearly done. Laptop's all good. GPU still needs to run 3DMark once, but then we're totally good. You look at our results here. The longer the Furmark goes, the GPU just slowly gets slower and slower and slower. Are you excited for tearing this laptop apart? Yeah. Now I was a bit of a dumb dumb and decided to use the Alienware X17. And like, I want to do that because it's really fast and I like it as a laptop, but doing this was really stupid because the disassembly process, it's not easy. This is not a simple laptop to take apart. Good job, Alex. Smart thinking. Everything that you need, like SSDs, battery, RAM is all pretty easy to access. Cooler, not so much. It's on the other side of this. Do you like taking laptops apart, David? Not even a little. Battery first. People always get really mad at me when I don't do that. You might be wondering, given how much of a pain in the ass this is to disassemble, why I choose to use it. The main reason is that most of our other really fast laptops are from Asus and Asus uses thermal paste on their VRMs instead of thermal pads, which means switching it to K5 Pro isn't really gonna give you much of a benefit. Don't you think the chances are that there's a random cable on the bottom that I need to disconnect, David? Pretty good. Wow. Okay. Wow, that's a lot of cooling. 17 CPU barrier. Wait, so it looks like that we have liquid metal on the CPU, but the GPU is just regular everyday thermal paste. So do we replace the liquid metal, David? I kind of feel like we should. Okay, you do it. Oh, spread around liquid metal, you piece of crap. Now we just have to put it back together and hope it all works. Here we go. Might've got a little bit of liquid metal on there. It's gonna make it go faster, right? Yeah. Perfect. She works good. Now we get to take apart a GPU. I really hope that Asus made this easy to disassemble. With them, it's normally kind of a toss up with the GPUs. While we take apart the GPU, let's get the laptop on the go. Initial looks, seems very close to stock. Oh, these are the guys where we'll probably get a lot of benefit from it getting replaced. This screw is basically stripped from the factory. That's gonna make getting it back in a joy. Oh, I hate doing this so much. Oh, no. One thing that's worth noting is that on cards and particularly motherboards, the really high-end models with really high-end VRMs might benefit less from K5 Pro than a lower-end model because these right here are probably very efficient and kept quite cool by all of this heatsink. All right. GPU repaste was a success. Laptop also looks like it's doing pretty good. Yeah, it's not even thermal throttling on the CPU. So I guess our liquid meddling is better than Alienware's. See you in another 30 minutes. My first impressions are it's pretty much margin of error between the two thermal pastes. I mean, Dell did a great job and so did Asus. I'm not super surprised given that these are incredibly high-end devices. Now the fun begins. And off the second time, cooler comes off. Get rid of these stupid little thermal pads. One millimeter, up to about three millimeters. It's still as good. Above that, what you wanna do is have like a paste copper shim and then paste again. Yeah, thermodynamics is frigging weird. I'm going to start just applying this as we go. You cannot really have too much. Oh, this is making a mess. Although that's a good thing. If you have too much of it, it's going to squish out and you'll be fine. If you don't have enough of it, you'll have an air gap and your components are going to overheat and die. The other benefit is that it can actually stop condensation from forming. Now why should this stuff be better than a thermal pad? This copper, although it may look fairly smooth, on a microscopic level is a whole bunch of little hills and valleys and crap. And that's what your thermal interface needs to get rid of. A thermal pad gets you about 60% contact on the surface. Whereas the K5 Pro is able to fill in 99% of all of those hills and valleys. Oh my God. Beautiful, isn't it? One thing you might be wondering looking at this is how do you get rid of it? When I asked computer systems about it, they were kind of like, why would you? It just works. It's incredibly stable. Why would you ever replace it? But apparently if you just soak it in alcohol for a bit, you can wipe it off and it's not too bad. How much squish do you expect, David? Yeah, I'm hoping for a lot of squish. Oh, bit of smoosh there. We're just protecting our components. I was expecting this to be way grosser looking. We used under a tub of the stuff for the laptop given we have a bunch of two millimeter ones on here. We're gonna need quite a bit for this GPU. It's so goopy. Oh, geez. I will not let you down computer systems. It is really important on chips like this that you cover the entire thing because there probably isn't much temperature sensing besides maybe a single probe in this. So if you miss half of it, it might overheat and not even know that it's overheating and kill itself. Oh, they can't say I didn't use enough. Tub of the stuff, I'm not gonna say it's overheating. They can't say I didn't use enough. Tub number three. Oh, I'm having a lot of fun but this may be disturbing to some viewers. Where would you rank this on like the tech gore you've seen, David? Six out of 10. Now what we have to do is run the tests. This is going to be a bit more involved figuring out if it worked or not because it isn't a simple look at temperature, it good. It's more like I have to go through all the frame times, organize it and then we'll be able to tell you if it worked or not. All right, it's the next morning and I've crunched the numbers. On the RTX 3090, the results are very clear. The repaste got us more FPS, 17 more actually in FirmArch and the K5 Pro got us an additional four FPS for a total gain of 21. This translates into a 6.3 increase in FPS and I've seen a lot of people go to a lot more trouble than this for less gains really. In F12020, it's a CPU bound game, so there was no change. As for the Alienware X17, if you want to repaste it, don't. Turns out their extra special element 31 that they talked about a whole bunch, yeah, it kicks ass. So when we replaced it, our performance dropped by seven FPS in FirmArch and in F12021, we lost three FPS. Fortunately, we were able to make up some of that by adding the K5 Pro, so our losses were halved in FirmArch and in F12021, we saw an incredible gain of one FPS, meaning that having your VRMs better cool on those laptops can make up for worse CPU temperatures. So am I going to put K5 Pro on everything? Well, the impressive part of this is that the K5 Pro is able to give us performance gains in brand new devices and brand new thermal pads. If your laptop or GPU is around two or three years old and you're already planning a repaste, I think including a tub of this stuff makes a lot of sense. I'm probably gonna order a bulk jar so that I don't have to use the stupid thermal pads that come with water blocks and cut them and stuff. Also applying it's pretty fun. Like the dirtiness of it.
