1 00:00:00,160 --> 00:00:08,360 Dude, check this out. ASRock has a 2 00:00:03,520 --> 00:00:12,320 Radeon 7900 XTX that is completely 3 00:00:08,360 --> 00:00:15,759 fanless. This is going to be great for 4 00:00:12,320 --> 00:00:18,160 about 30 seconds. Then it starts to 5 00:00:15,759 --> 00:00:22,560 thermal throttle dramatically. Are you sure you don't want something 6 00:00:19,520 --> 00:00:25,920 with a fan on? No, no, no, no. See, this 7 00:00:22,560 --> 00:00:28,400 this was part of the plan. I have always 8 00:00:25,920 --> 00:00:33,320 wanted to take one of these server oriented desktop cards with the no fans 9 00:00:31,119 --> 00:00:38,640 on them and hook it up to an air conditioner. Get it? AC PC. How in the 10 00:00:37,120 --> 00:00:42,800 hell is this going to work? I don't know. You're smart. You'll figure it 11 00:00:40,399 --> 00:00:45,840 out. Gosh, look at the time. I've got a meeting to get our way to. Oh, and uh 12 00:00:44,399 --> 00:00:51,600 one more thing. While you're at it, can you remove all the other fans from the system? I want it completely silent. Not 13 00:00:49,520 --> 00:00:54,879 so fast. If you've always wanted to try this, then you're helping out. First, 14 00:00:53,360 --> 00:00:59,920 we're going to take a closer look at the AC 516S portable smart air conditioner 15 00:00:57,600 --> 00:01:05,760 from our sponsor for this video, Drio. It's a 14,000 BTU model, which is 16 00:01:02,559 --> 00:01:08,320 designed to cool up to 450 ft. So, it 17 00:01:05,760 --> 00:01:12,159 should be plenty for a couple square ft of computer with capacity to spare, 18 00:01:10,479 --> 00:01:17,759 meaning that when we're done, we will have built the first ever gaming PC that 19 00:01:15,200 --> 00:01:21,680 actively cools your room. Well, this is nice and flat. So, I think the easiest 20 00:01:19,840 --> 00:01:25,280 way to get the air to the PC is going to be just some kind of shroud and a pipe. 21 00:01:23,759 --> 00:01:28,640 Yeah, that's great. Why don't we mock it up with this foam board? I mean, I had 22 00:01:26,799 --> 00:01:34,560 something a little prettier in mind, but Well, we got to make sure it works first, right? Okay. Oh, did someone 23 00:01:31,600 --> 00:01:37,200 already do the work for me? I did. Wow. I thought you were going to make me do 24 00:01:35,680 --> 00:01:40,640 the work today. Well, you do some of the work. Okay. Remember, kids, always cut 25 00:01:39,280 --> 00:01:46,399 toward yourself. That way, you can see what you're doing. You can't get hit by a train if you see it coming. 26 00:01:44,720 --> 00:01:52,240 Don't worry, my balls already don't work anyway. Okay, 27 00:01:48,880 --> 00:01:54,640 that's not bad. Okay. Okay. Well, she's 28 00:01:52,240 --> 00:01:58,079 not completely airtight, but she also doesn't need to be. And this should be 29 00:01:56,320 --> 00:02:05,040 good enough for us to get a quick test. Want to see if air is going to move, right? Hey, not bad. Now, this could be 30 00:02:03,040 --> 00:02:09,119 a little restrictive. In a perfect world, we might want to step down the 31 00:02:06,479 --> 00:02:13,599 exhaust to a bigger circle, then step it down to our smaller one. But again, this 32 00:02:12,000 --> 00:02:18,239 is just proof of concept. We want to know if it's kind of going to work. All right. How's that feel? Glorious. There 33 00:02:17,120 --> 00:02:21,680 you go. Is that better? Oh, that's beautiful. Where are you exhausting this 34 00:02:20,160 --> 00:02:30,120 to? I mean, normally it would be a window. The window right there. Yeah, but that window doesn't open. Why not? 35 00:02:25,640 --> 00:02:34,879 Um Oh, yeah. That's how they work. Oh 36 00:02:30,120 --> 00:02:36,480 my. Oh, not ideal. Um, okay. You're not 37 00:02:34,879 --> 00:02:41,680 really supposed to run a compressor sideways and then It was very brief. 38 00:02:38,959 --> 00:02:45,440 That was not the Oh my god. Did this seriously just like totally survive? 39 00:02:43,760 --> 00:02:51,440 It's our best design ever, man. Let me tell you. Okay. So, what I'm thinking 40 00:02:48,400 --> 00:02:53,120 Yeah. Go into the front here with like 41 00:02:51,440 --> 00:02:57,519 kind of a manifold and then we can have shrouds on the things. Oh, shrouds. 42 00:02:55,200 --> 00:03:01,120 Okay. Like duct mod kind of idea. Sure. So, we have one over the CPU. Yeah. Cuz 43 00:02:59,680 --> 00:03:06,319 you don't like this fan apparently. Well, I kind of think we should start with the CPU fan being the CPU fan cuz 44 00:03:04,959 --> 00:03:11,519 this really doesn't feel like much. I pulled it out. So, you know. So, we're putting this on the front. Let's do this 45 00:03:09,040 --> 00:03:14,879 for now. See if it works. Oh my god. Fired up. We just have to prove that it 46 00:03:13,360 --> 00:03:19,120 works and then we can make something good. Have we done anything to make them 47 00:03:17,840 --> 00:03:24,800 believe that we will make something good? I mean, we've done a lot of videos. They must believe something. 48 00:03:22,319 --> 00:03:29,599 Yeah, there's been some good ones. Did it turn on? Yeah. Somehow everything 49 00:03:27,680 --> 00:03:32,799 still works. It's impressive how quiet the compressor is. Hey, the fans too 50 00:03:31,599 --> 00:03:38,959 actually are pretty silent. I'm surprised even after dropping it. They claim it runs at 46 dB, which is pretty 51 00:03:37,040 --> 00:03:43,360 reasonable for a unit of this capacity. Now, I noticed that the compressor is 52 00:03:40,720 --> 00:03:46,879 cycling pretty often. That's on purpose. Yeah, that makes sense for room air 53 00:03:45,599 --> 00:03:51,680 conditioning because you got your thermal sensor going into the unit and it's going, "Okay, do is our temperature 54 00:03:50,080 --> 00:03:54,720 good enough?" It's not great for what we're doing where we might want 100% 55 00:03:53,440 --> 00:04:00,560 output all the time. We'll have to figure that out. Wow, our CPU is at 16° 56 00:03:58,000 --> 00:04:03,760 and our GPU is at 33. Nice. Neither of them are doing anything yet, though. So, 57 00:04:01,920 --> 00:04:07,200 give us time. Let us cook. And the CPU is up to 32 immediately. Still cold 58 00:04:05,519 --> 00:04:13,280 exhaust. You know what's the craziest part of this is that the cost of buying 59 00:04:10,400 --> 00:04:16,959 a window AC unit actually not that far off like getting a custom water block 60 00:04:15,280 --> 00:04:22,240 system. Like should we just be ducting chilled air into our systems? Maybe. Not 61 00:04:19,320 --> 00:04:26,160 necessarily. Spoiler. Condensation can be a major issue when you are plumbing 62 00:04:24,240 --> 00:04:28,960 cold air directly into a warm environment, but we'll get to that 63 00:04:27,360 --> 00:04:33,840 later. So, we're back to running smooth again. For how long? I don't know. That 64 00:04:31,120 --> 00:04:39,040 coil wine though is Wow. Okay. GPU is getting pretty warm. It's only at around 65 00:04:35,840 --> 00:04:41,199 70° still. Okay. The CPU is sitting at 66 00:04:39,040 --> 00:04:47,040 27 though, which is perfectly reasonable for a gaming load. Hold on. It just 67 00:04:42,880 --> 00:04:51,680 dropped to 2050, 2020, 2000. Oh, no. 68 00:04:47,040 --> 00:04:53,199 1990. What did I do? Good year. 69 00:04:51,680 --> 00:04:57,520 So, it's not perfect, but we weren't expecting it to be. What we have found, 70 00:04:55,120 --> 00:05:01,600 though, is that it's not dropping as low or as fast as when we were running 71 00:04:59,840 --> 00:05:05,199 without the duct. I want to see what we're going to land at. We're at 100 72 00:05:03,280 --> 00:05:10,720 degrees on the GPU, which is obviously not ideal, but we're at 1500 MHz. So, 73 00:05:08,880 --> 00:05:16,560 while we're at the same temperature, we are running at 4x 5x the clock speed. 74 00:05:14,479 --> 00:05:20,680 Yeah, that's a pretty big deal. We're settling in around 1400. And you can 75 00:05:18,479 --> 00:05:24,320 actually see a difference in the smoothness with the cool ducted air 76 00:05:22,880 --> 00:05:27,520 heading toward it. And that's not even blowing right through the heat sink yet. 77 00:05:25,919 --> 00:05:30,639 I think this is pretty promising. Let's put some more work into it. Now we're 78 00:05:29,039 --> 00:05:37,520 going to switch over to the other AC unit that we did bad things to. Okay. 79 00:05:34,039 --> 00:05:39,520 Ah, dots for 3D scanning. Exactly. We 3D 80 00:05:37,520 --> 00:05:43,039 scanned the surface here. Wicked smart. And that's to get a better seal against 81 00:05:40,960 --> 00:05:47,360 it, I assume. Exactly. Okay. Let's have a look. We also made a little tweak to 82 00:05:45,360 --> 00:05:51,039 this one. We took the thermister, which usually lives inside the evaporator. If 83 00:05:49,600 --> 00:05:54,400 that gets too cold, it turns off the compressor, but we don't want that. No, 84 00:05:52,960 --> 00:05:59,360 we want it to just keep running. So, we just kind of stuck it out of the way and 85 00:05:56,479 --> 00:06:02,000 it'll just run forever now. Okay. So, we might get some condensation on the back, 86 00:06:00,560 --> 00:06:05,520 but we can deal with that later. Yeah. Normally, this is like a condensation 87 00:06:03,759 --> 00:06:09,319 free unit, right? Yeah. They capture the liquid internally and recycle it and 88 00:06:07,360 --> 00:06:14,919 evaporate it. Ooh, that's fancy. Don't eat that. I 89 00:06:12,960 --> 00:06:19,039 wasn't going to eat it. Is there a reason we wanted it 90 00:06:17,120 --> 00:06:23,280 pointing down? Uh, because of the way the baffles work in there. They're kind 91 00:06:21,120 --> 00:06:27,120 of aiming this way. Got it. Makes sense. The main issue with our mockup though 92 00:06:24,880 --> 00:06:32,560 was not getting the cold air off of the AC unit. It was getting that cold air 93 00:06:29,199 --> 00:06:36,720 plumbed up to our components. So that is 94 00:06:32,560 --> 00:06:39,680 where these shrouds come in. Uh so this 95 00:06:36,720 --> 00:06:44,319 goes on the outside. Yes. Air goes in. Okay. Air comes out of them and we'll 96 00:06:41,840 --> 00:06:47,840 get into the components through those. It's funny cuz I've used air 97 00:06:45,520 --> 00:06:52,080 conditioners to cool PCs lots of times. It's just always been to chill coolant 98 00:06:50,319 --> 00:06:57,280 that I then pump through a water cooling system. I've never really just chilled 99 00:06:54,800 --> 00:07:01,680 an air cooled computer. Well, I shouldn't say never. Like, I took that 100 00:06:59,039 --> 00:07:07,039 one outside to the NCX parking lot 17 years ago or whatever. But see, how 101 00:07:03,360 --> 00:07:07,039 great is that low back force? 102 00:07:07,240 --> 00:07:12,960 Huh? What? It's a good product. We just can't stop you from shilling, can we? 103 00:07:11,520 --> 00:07:16,800 It's not shilling if it's a good product that you believe in. What the heck 104 00:07:14,800 --> 00:07:20,639 happened to this? Okay, so we thought that this little guy here Yeah. was the 105 00:07:19,120 --> 00:07:24,960 temperature sensor, right? That makes sense. So, we were blowing a hot air gun 106 00:07:22,560 --> 00:07:29,120 at it to try to make the thing run constantly, right? Turns out that's the 107 00:07:27,039 --> 00:07:34,800 humidity sensor, right? And also, that's kind of melty, right? Wo, that's 108 00:07:32,759 --> 00:07:39,199 awesome. We're going to put that cold air right down the fins. That' be 109 00:07:36,720 --> 00:07:44,800 perfect. I am a little concerned that the fin density on the GPU is a little 110 00:07:42,240 --> 00:07:47,840 bit higher than on the CPU, so there might be more back pressure and 111 00:07:46,240 --> 00:07:52,800 therefore we might get Oh my god, it's still really hot. We might get less flow 112 00:07:50,479 --> 00:07:56,240 through the GPU, but we're going to have to see how it goes. We would never 113 00:07:54,560 --> 00:07:59,680 recommend putting this much strain on a 12vt high power connector. What could 114 00:07:58,240 --> 00:08:04,800 possibly go wrong with these connectors, though? Yeah, maybe just wrap it. Yeah, 115 00:08:02,560 --> 00:08:09,199 there we go. If you have an AC in your room anyway, what is a good reason not 116 00:08:07,360 --> 00:08:13,199 to do this? I mean, this thing is what, 14,000 BTUs? Yeah, that's what 4,000 117 00:08:12,000 --> 00:08:18,000 watts, something like that. Yeah, something like that. So, we can we can do way more cooling than we're going to 118 00:08:16,080 --> 00:08:21,919 put out here, which means if our components get too cold and then warm up 119 00:08:20,000 --> 00:08:26,319 in the warm air and water can form on them and then everything's bad. But it's 120 00:08:24,160 --> 00:08:32,159 possible, and we haven't tried this yet, it's possible that the system will work 121 00:08:29,680 --> 00:08:36,000 even when the AC is not running. True. So, we could just have like potentially 122 00:08:34,240 --> 00:08:39,599 you could configure a system so that you have just normal operation and it just 123 00:08:38,000 --> 00:08:44,000 works off of your room's temperature like any other air conditioner would. 124 00:08:41,760 --> 00:08:47,600 But you could have like like turbo mode and run the AC continuously if you want 125 00:08:45,839 --> 00:08:51,600 to like, you know, I don't know, overclock. Oh, dude, I can smell the 126 00:08:49,519 --> 00:08:55,200 flawless victory from here. We could use an insulated hose here to try to keep a 127 00:08:53,519 --> 00:08:59,839 little bit more of the cool air in, but I think this is going to work pretty well as it is. Yeah, I think we're going 128 00:08:57,839 --> 00:09:05,120 to be fine. And when we consider that the area we're trying to cool ultimately 129 00:09:02,640 --> 00:09:09,360 is the room, we don't really care if we have any losses of coolness into the 130 00:09:07,920 --> 00:09:15,200 room around us anyway. As long as there's enough going to the PC, we're 131 00:09:11,440 --> 00:09:17,519 fine. Yeah, there she goes. Not going to 132 00:09:15,200 --> 00:09:22,480 lie, I'm still not feeling much out of that GPU. Dude, we may need to put some 133 00:09:20,640 --> 00:09:25,560 kind of baffle or something in to make sure that we're not sending all of the 134 00:09:24,160 --> 00:09:30,000 air flow to the CPU. What Jordan's trying to demonstrate 135 00:09:28,080 --> 00:09:33,279 is that obviously if you were to set something like this up at home, which 136 00:09:31,360 --> 00:09:37,120 we're not necessarily recommending, you would want to have the AC unit itself 137 00:09:35,279 --> 00:09:40,240 farther away so that you get a noise benefit. And that's where something like 138 00:09:38,480 --> 00:09:43,839 an insulated duct would come in to make sure that it's still running at optimal 139 00:09:41,680 --> 00:09:49,279 efficiency while giving you that sweet, sweet silence. Of course, none of that's 140 00:09:46,480 --> 00:09:56,880 going to be very useful if it doesn't work. Oh no, Jordan. Yeah, buddy. Our 141 00:09:53,519 --> 00:10:00,640 CPU is at 17°. That seems a little cool. 142 00:09:56,880 --> 00:10:02,560 But our GPU is at 90. Okay, I think we 143 00:10:00,640 --> 00:10:08,399 need to put more baffel in. Yeah, the CPU needs like nothing. Interesting. 144 00:10:06,160 --> 00:10:12,080 Oh, this is so nice. Sorry, computer. I need this more than you right now. Now, 145 00:10:10,480 --> 00:10:17,600 you might have noticed something. We have the hot side blowing at the 146 00:10:14,279 --> 00:10:20,399 evaporator. That is to maybe hopefully 147 00:10:17,600 --> 00:10:23,360 help keep ice from forming on it. Yeah, cuz we overrode the whole no 148 00:10:21,920 --> 00:10:28,320 condensation thing. Remember that? I don't know if it's going to work or not, but it's here. Oh, dude, we're down to 149 00:10:26,399 --> 00:10:35,920 82. Oh, dude, I'm starting to get excited now. Okay, now this is getting 150 00:10:31,079 --> 00:10:38,640 cool. 80. We're at 80 now. 76. Dude, 151 00:10:35,920 --> 00:10:43,600 every single tiny gap that I plug, we are getting extra performance. Dude, she 152 00:10:40,959 --> 00:10:48,079 works awesome. And what's really cool is we're still throwing all this cold air 153 00:10:45,760 --> 00:10:52,079 out into our room. The air coming off the GPU is actually pretty toasty. 154 00:10:50,560 --> 00:10:57,120 Little warm. I think we would need, like you said, to tweak the baffle system a 155 00:10:54,160 --> 00:11:02,399 little bit or create a less turbulent path for the air into the GPU to try to 156 00:10:59,920 --> 00:11:05,600 focus it down there or even use a GPU that doesn't have such a tiny little 157 00:11:03,600 --> 00:11:09,040 heat sink on it. But overall, we're still getting cold air off of the back 158 00:11:07,360 --> 00:11:12,720 of the system. Yeah. Everything that's coming through the CPU is like freaking 159 00:11:10,800 --> 00:11:17,519 cold. That's great. Yeah. So, we're cooling our room and our PC and we have 160 00:11:15,200 --> 00:11:21,040 no fans in this thing. Well, power supply. Okay. Power supply fan. Somebody 161 00:11:19,600 --> 00:11:25,680 stole somebody stole the only good power supply with fanless. Stupid question. 162 00:11:23,519 --> 00:11:30,079 Yeah. Turn the computer this way. Yes. Make this go straight. I was about to We 163 00:11:28,320 --> 00:11:34,399 were on the same wavelength, Jordan. Same wavelength. Let's see if we can 164 00:11:32,000 --> 00:11:39,120 reduce our losses here a little bit. 76 didn't really make a difference. What 165 00:11:36,000 --> 00:11:42,800 about moving it up? Let's get our path 166 00:11:39,120 --> 00:11:44,800 as direct as possible here. Okay. I can 167 00:11:42,800 --> 00:11:49,600 No, I can feel more air flow off the GPU for sure. There's a hand in my way. Oh, 168 00:11:46,640 --> 00:11:54,480 sorry. Yep. It's still hot. But it's a lot more. We're down to 74. And 169 00:11:52,000 --> 00:11:58,240 remember, we settled in around 76. So, let's see if we get a little bit more 170 00:11:55,760 --> 00:12:01,760 out of it here. This is getting a little damp now. Double wall. So, you'd 171 00:12:00,079 --> 00:12:05,839 probably want to insulate the whole shebang. Actually, this especially, 172 00:12:04,480 --> 00:12:09,920 yeah, where you're going to get like condensation dripping off this in the 173 00:12:07,760 --> 00:12:12,959 longer term. 71. That's the lowest temp we've seen so far, though. So, that's an 174 00:12:11,680 --> 00:12:17,279 interesting thought. So you'd want insulated lines and then you'd probably 175 00:12:15,279 --> 00:12:20,800 want like an accelerator fan at a midpoint just in order to increase the 176 00:12:19,200 --> 00:12:24,079 pressure cuz this is not designed for high static pressure. No, not at all. 177 00:12:22,560 --> 00:12:27,600 This is designed to just throw cold air out into the room. Blast of fuel in the 178 00:12:25,680 --> 00:12:31,120 room. Yeah. So in order to overcome the losses from the tubing and from the 179 00:12:29,440 --> 00:12:34,959 fins, you'd probably want to add like an accelerator fan that's somewhat balanced 180 00:12:33,279 --> 00:12:41,440 with the output of this. But there's a ton of potential. Final temperature, a 181 00:12:37,440 --> 00:12:43,680 nice 69° under load in Valheim. And all 182 00:12:41,440 --> 00:12:47,600 it cost us was the risk of condensation forming, which is going to happen 183 00:12:45,519 --> 00:12:51,600 anytime you have a cold surface and warm air. So, if we were to deploy something 184 00:12:49,839 --> 00:12:56,240 like this longer term, we would want to put some kind of insulation on 185 00:12:53,519 --> 00:13:00,480 everything from our ducting to any 3D printed components and especially on 186 00:12:58,560 --> 00:13:06,480 anywhere inside the system where cold air is going to be. But with that said, 187 00:13:03,920 --> 00:13:10,800 I don't think this is actually that wild of a concept for someone to do at home 188 00:13:08,880 --> 00:13:16,480 if you're going to have the AC. Anyway, look at these CPU temps. It's sitting at 189 00:13:13,120 --> 00:13:19,480 anywhere from 11 to 14° in games. And 190 00:13:16,480 --> 00:13:22,639 this is what What do we have in here? A 191 00:13:19,480 --> 00:13:24,480 12700K. That is flipping awesome. You 192 00:13:22,639 --> 00:13:28,399 don't have to use a Drio AC for this kind of shenanigans. In fact, I'm sure 193 00:13:26,800 --> 00:13:32,000 they'd probably prefer if you don't. You just use it to clean your room. But hey, 194 00:13:30,320 --> 00:13:37,920 massive shout out to them for sponsoring this video and letting us uh gently 195 00:13:35,440 --> 00:13:41,680 abuse their machines, maybe. Yeah, not so gently. They also sent over this room 196 00:13:39,920 --> 00:13:45,040 fan, which actually I was kind of impressed by. It's super quiet, and I 197 00:13:43,360 --> 00:13:48,880 like the way that it can oscillate in all kinds of different directions. We're 198 00:13:46,800 --> 00:13:52,560 going to have it and the AC unit linked in the video description, as well as a 199 00:13:50,959 --> 00:13:56,000 limited time discount, so you can find all the details down there. If you guys 200 00:13:54,560 --> 00:14:00,079 enjoyed this video, oh, why don't you check out the playlist? We have a janky 201 00:13:57,920 --> 00:14:05,120 cooling playlist. With all the times we've done bizarre stuff like this, this 202 00:14:02,480 --> 00:14:05,120 is one of them.
