WEBVTT

00:00:00.160 --> 00:00:08.360
Dude, check this out. ASRock has a

00:00:03.520 --> 00:00:12.320
Radeon 7900 XTX that is completely

00:00:08.360 --> 00:00:15.759
fanless. This is going to be great for

00:00:12.320 --> 00:00:18.160
about 30 seconds. Then it starts to

00:00:15.759 --> 00:00:22.560
thermal throttle dramatically. Are you sure you don't want something

00:00:19.520 --> 00:00:25.920
with a fan on? No, no, no, no. See, this

00:00:22.560 --> 00:00:28.400
this was part of the plan. I have always

00:00:25.920 --> 00:00:33.320
wanted to take one of these server oriented desktop cards with the no fans

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

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

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

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

00:00:49.520 --> 00:00:54.879
so fast. If you've always wanted to try this, then you're helping out. First,

00:00:53.360 --> 00:00:59.920
we're going to take a closer look at the AC 516S portable smart air conditioner

00:00:57.600 --> 00:01:05.760
from our sponsor for this video, Drio. It's a 14,000 BTU model, which is

00:01:02.559 --> 00:01:08.320
designed to cool up to 450 ft. So, it

00:01:05.760 --> 00:01:12.159
should be plenty for a couple square ft of computer with capacity to spare,

00:01:10.479 --> 00:01:17.759
meaning that when we're done, we will have built the first ever gaming PC that

00:01:15.200 --> 00:01:21.680
actively cools your room. Well, this is nice and flat. So, I think the easiest

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.

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

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

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

00:01:35.680 --> 00:01:40.640
the work today. Well, you do some of the work. Okay. Remember, kids, always cut

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.

00:01:44.720 --> 00:01:52.240
Don't worry, my balls already don't work anyway. Okay,

00:01:48.880 --> 00:01:54.640
that's not bad. Okay. Okay. Well, she's

00:01:52.240 --> 00:01:58.079
not completely airtight, but she also doesn't need to be. And this should be

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

00:02:03.040 --> 00:02:09.119
a little restrictive. In a perfect world, we might want to step down the

00:02:06.479 --> 00:02:13.599
exhaust to a bigger circle, then step it down to our smaller one. But again, this

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

00:02:17.120 --> 00:02:21.680
you go. Is that better? Oh, that's beautiful. Where are you exhausting this

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?

00:02:25.640 --> 00:02:34.879
Um Oh, yeah. That's how they work. Oh

00:02:30.120 --> 00:02:36.480
my. Oh, not ideal. Um, okay. You're not

00:02:34.879 --> 00:02:41.680
really supposed to run a compressor sideways and then It was very brief.

00:02:38.959 --> 00:02:45.440
That was not the Oh my god. Did this seriously just like totally survive?

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

00:02:48.400 --> 00:02:53.120
Yeah. Go into the front here with like

00:02:51.440 --> 00:02:57.519
kind of a manifold and then we can have shrouds on the things. Oh, shrouds.

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

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

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

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

00:03:13.360 --> 00:03:19.120
works and then we can make something good. Have we done anything to make them

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.

00:03:22.319 --> 00:03:29.599
Yeah, there's been some good ones. Did it turn on? Yeah. Somehow everything

00:03:27.680 --> 00:03:32.799
still works. It's impressive how quiet the compressor is. Hey, the fans too

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

00:03:37.040 --> 00:03:43.360
reasonable for a unit of this capacity. Now, I noticed that the compressor is

00:03:40.720 --> 00:03:46.879
cycling pretty often. That's on purpose. Yeah, that makes sense for room air

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

00:03:50.080 --> 00:03:54.720
good enough?" It's not great for what we're doing where we might want 100%

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°

00:03:58.000 --> 00:04:03.760
and our GPU is at 33. Nice. Neither of them are doing anything yet, though. So,

00:04:01.920 --> 00:04:07.200
give us time. Let us cook. And the CPU is up to 32 immediately. Still cold

00:04:05.519 --> 00:04:13.280
exhaust. You know what's the craziest part of this is that the cost of buying

00:04:10.400 --> 00:04:16.959
a window AC unit actually not that far off like getting a custom water block

00:04:15.280 --> 00:04:22.240
system. Like should we just be ducting chilled air into our systems? Maybe. Not

00:04:19.320 --> 00:04:26.160
necessarily. Spoiler. Condensation can be a major issue when you are plumbing

00:04:24.240 --> 00:04:28.960
cold air directly into a warm environment, but we'll get to that

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

00:04:31.120 --> 00:04:39.040
coil wine though is Wow. Okay. GPU is getting pretty warm. It's only at around

00:04:35.840 --> 00:04:41.199
70° still. Okay. The CPU is sitting at

00:04:39.040 --> 00:04:47.040
27 though, which is perfectly reasonable for a gaming load. Hold on. It just

00:04:42.880 --> 00:04:51.680
dropped to 2050, 2020, 2000. Oh, no.

00:04:47.040 --> 00:04:53.199
1990. What did I do? Good year.

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,

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

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

00:05:03.280 --> 00:05:10.720
degrees on the GPU, which is obviously not ideal, but we're at 1500 MHz. So,

00:05:08.880 --> 00:05:16.560
while we're at the same temperature, we are running at 4x 5x the clock speed.

00:05:14.479 --> 00:05:20.680
Yeah, that's a pretty big deal. We're settling in around 1400. And you can

00:05:18.479 --> 00:05:24.320
actually see a difference in the smoothness with the cool ducted air

00:05:22.880 --> 00:05:27.520
heading toward it. And that's not even blowing right through the heat sink yet.

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

00:05:29.039 --> 00:05:37.520
going to switch over to the other AC unit that we did bad things to. Okay.

00:05:34.039 --> 00:05:39.520
Ah, dots for 3D scanning. Exactly. We 3D

00:05:37.520 --> 00:05:43.039
scanned the surface here. Wicked smart. And that's to get a better seal against

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

00:05:45.360 --> 00:05:51.039
this one. We took the thermister, which usually lives inside the evaporator. If

00:05:49.600 --> 00:05:54.400
that gets too cold, it turns off the compressor, but we don't want that. No,

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

00:05:56.479 --> 00:06:02.000
it'll just run forever now. Okay. So, we might get some condensation on the back,

00:06:00.560 --> 00:06:05.520
but we can deal with that later. Yeah. Normally, this is like a condensation

00:06:03.759 --> 00:06:09.319
free unit, right? Yeah. They capture the liquid internally and recycle it and

00:06:07.360 --> 00:06:14.919
evaporate it. Ooh, that's fancy. Don't eat that. I

00:06:12.960 --> 00:06:19.039
wasn't going to eat it. Is there a reason we wanted it

00:06:17.120 --> 00:06:23.280
pointing down? Uh, because of the way the baffles work in there. They're kind

00:06:21.120 --> 00:06:27.120
of aiming this way. Got it. Makes sense. The main issue with our mockup though

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

00:06:29.199 --> 00:06:36.720
plumbed up to our components. So that is

00:06:32.560 --> 00:06:39.680
where these shrouds come in. Uh so this

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

00:06:41.840 --> 00:06:47.840
get into the components through those. It's funny cuz I've used air

00:06:45.520 --> 00:06:52.080
conditioners to cool PCs lots of times. It's just always been to chill coolant

00:06:50.319 --> 00:06:57.280
that I then pump through a water cooling system. I've never really just chilled

00:06:54.800 --> 00:07:01.680
an air cooled computer. Well, I shouldn't say never. Like, I took that

00:06:59.039 --> 00:07:07.039
one outside to the NCX parking lot 17 years ago or whatever. But see, how

00:07:03.360 --> 00:07:07.039
great is that low back force?

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?

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

00:07:14.800 --> 00:07:20.639
happened to this? Okay, so we thought that this little guy here Yeah. was the

00:07:19.120 --> 00:07:24.960
temperature sensor, right? That makes sense. So, we were blowing a hot air gun

00:07:22.560 --> 00:07:29.120
at it to try to make the thing run constantly, right? Turns out that's the

00:07:27.039 --> 00:07:34.800
humidity sensor, right? And also, that's kind of melty, right? Wo, that's

00:07:32.759 --> 00:07:39.199
awesome. We're going to put that cold air right down the fins. That' be

00:07:36.720 --> 00:07:44.800
perfect. I am a little concerned that the fin density on the GPU is a little

00:07:42.240 --> 00:07:47.840
bit higher than on the CPU, so there might be more back pressure and

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

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

00:07:54.560 --> 00:07:59.680
recommend putting this much strain on a 12vt high power connector. What could

00:07:58.240 --> 00:08:04.800
possibly go wrong with these connectors, though? Yeah, maybe just wrap it. Yeah,

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

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

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

00:08:16.080 --> 00:08:21.919
put out here, which means if our components get too cold and then warm up

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

00:08:24.160 --> 00:08:32.159
possible, and we haven't tried this yet, it's possible that the system will work

00:08:29.680 --> 00:08:36.000
even when the AC is not running. True. So, we could just have like potentially

00:08:34.240 --> 00:08:39.599
you could configure a system so that you have just normal operation and it just

00:08:38.000 --> 00:08:44.000
works off of your room's temperature like any other air conditioner would.

00:08:41.760 --> 00:08:47.600
But you could have like like turbo mode and run the AC continuously if you want

00:08:45.839 --> 00:08:51.600
to like, you know, I don't know, overclock. Oh, dude, I can smell the

00:08:49.519 --> 00:08:55.200
flawless victory from here. We could use an insulated hose here to try to keep a

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

00:08:57.839 --> 00:09:05.120
to be fine. And when we consider that the area we're trying to cool ultimately

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

00:09:07.920 --> 00:09:15.200
room around us anyway. As long as there's enough going to the PC, we're

00:09:11.440 --> 00:09:17.519
fine. Yeah, there she goes. Not going to

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

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

00:09:24.160 --> 00:09:30.000
air flow to the CPU. What Jordan's trying to demonstrate

00:09:28.080 --> 00:09:33.279
is that obviously if you were to set something like this up at home, which

00:09:31.360 --> 00:09:37.120
we're not necessarily recommending, you would want to have the AC unit itself

00:09:35.279 --> 00:09:40.240
farther away so that you get a noise benefit. And that's where something like

00:09:38.480 --> 00:09:43.839
an insulated duct would come in to make sure that it's still running at optimal

00:09:41.680 --> 00:09:49.279
efficiency while giving you that sweet, sweet silence. Of course, none of that's

00:09:46.480 --> 00:09:56.880
going to be very useful if it doesn't work. Oh no, Jordan. Yeah, buddy. Our

00:09:53.519 --> 00:10:00.640
CPU is at 17°. That seems a little cool.

00:09:56.880 --> 00:10:02.560
But our GPU is at 90. Okay, I think we

00:10:00.640 --> 00:10:08.399
need to put more baffel in. Yeah, the CPU needs like nothing. Interesting.

00:10:06.160 --> 00:10:12.080
Oh, this is so nice. Sorry, computer. I need this more than you right now. Now,

00:10:10.480 --> 00:10:17.600
you might have noticed something. We have the hot side blowing at the

00:10:14.279 --> 00:10:20.399
evaporator. That is to maybe hopefully

00:10:17.600 --> 00:10:23.360
help keep ice from forming on it. Yeah, cuz we overrode the whole no

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

00:10:26.399 --> 00:10:35.920
82. Oh, dude, I'm starting to get excited now. Okay, now this is getting

00:10:31.079 --> 00:10:38.640
cool. 80. We're at 80 now. 76. Dude,

00:10:35.920 --> 00:10:43.600
every single tiny gap that I plug, we are getting extra performance. Dude, she

00:10:40.959 --> 00:10:48.079
works awesome. And what's really cool is we're still throwing all this cold air

00:10:45.760 --> 00:10:52.079
out into our room. The air coming off the GPU is actually pretty toasty.

00:10:50.560 --> 00:10:57.120
Little warm. I think we would need, like you said, to tweak the baffle system a

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

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

00:11:03.600 --> 00:11:09.040
heat sink on it. But overall, we're still getting cold air off of the back

00:11:07.360 --> 00:11:12.720
of the system. Yeah. Everything that's coming through the CPU is like freaking

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

00:11:15.200 --> 00:11:21.040
no fans in this thing. Well, power supply. Okay. Power supply fan. Somebody

00:11:19.600 --> 00:11:25.680
stole somebody stole the only good power supply with fanless. Stupid question.

00:11:23.519 --> 00:11:30.079
Yeah. Turn the computer this way. Yes. Make this go straight. I was about to We

00:11:28.320 --> 00:11:34.399
were on the same wavelength, Jordan. Same wavelength. Let's see if we can

00:11:32.000 --> 00:11:39.120
reduce our losses here a little bit. 76 didn't really make a difference. What

00:11:36.000 --> 00:11:42.800
about moving it up? Let's get our path

00:11:39.120 --> 00:11:44.800
as direct as possible here. Okay. I can

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,

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

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

00:11:55.760 --> 00:12:01.760
out of it here. This is getting a little damp now. Double wall. So, you'd

00:12:00.079 --> 00:12:05.839
probably want to insulate the whole shebang. Actually, this especially,

00:12:04.480 --> 00:12:09.920
yeah, where you're going to get like condensation dripping off this in the

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

00:12:11.680 --> 00:12:17.279
interesting thought. So you'd want insulated lines and then you'd probably

00:12:15.279 --> 00:12:20.800
want like an accelerator fan at a midpoint just in order to increase the

00:12:19.200 --> 00:12:24.079
pressure cuz this is not designed for high static pressure. No, not at all.

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

00:12:25.680 --> 00:12:31.120
room. Yeah. So in order to overcome the losses from the tubing and from the

00:12:29.440 --> 00:12:34.959
fins, you'd probably want to add like an accelerator fan that's somewhat balanced

00:12:33.279 --> 00:12:41.440
with the output of this. But there's a ton of potential. Final temperature, a

00:12:37.440 --> 00:12:43.680
nice 69° under load in Valheim. And all

00:12:41.440 --> 00:12:47.600
it cost us was the risk of condensation forming, which is going to happen

00:12:45.519 --> 00:12:51.600
anytime you have a cold surface and warm air. So, if we were to deploy something

00:12:49.839 --> 00:12:56.240
like this longer term, we would want to put some kind of insulation on

00:12:53.519 --> 00:13:00.480
everything from our ducting to any 3D printed components and especially on

00:12:58.560 --> 00:13:06.480
anywhere inside the system where cold air is going to be. But with that said,

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

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

00:13:13.120 --> 00:13:19.480
anywhere from 11 to 14° in games. And

00:13:16.480 --> 00:13:22.639
this is what What do we have in here? A

00:13:19.480 --> 00:13:24.480
12700K. That is flipping awesome. You

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

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,

00:13:30.320 --> 00:13:37.920
massive shout out to them for sponsoring this video and letting us uh gently

00:13:35.440 --> 00:13:41.680
abuse their machines, maybe. Yeah, not so gently. They also sent over this room

00:13:39.920 --> 00:13:45.040
fan, which actually I was kind of impressed by. It's super quiet, and I

00:13:43.360 --> 00:13:48.880
like the way that it can oscillate in all kinds of different directions. We're

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

00:13:50.959 --> 00:13:56.000
limited time discount, so you can find all the details down there. If you guys

00:13:54.560 --> 00:14:00.079
enjoyed this video, oh, why don't you check out the playlist? We have a janky

00:13:57.920 --> 00:14:05.120
cooling playlist. With all the times we've done bizarre stuff like this, this

00:14:02.480 --> 00:14:05.120
is one of them.
