00:00:00.160 --> 00:00:07.759
As you may already know, we bought a fire truck, which can mean only one

00:00:05.440 --> 00:00:10.000
thing. We're going to cool a computer with

00:00:12.920 --> 00:00:20.160
it. Obviously, this would have worked a little better if we plumbed up some

00:00:17.199 --> 00:00:25.600
water blocks, but here's the rub. A fire truck can reach up to 200 PSI of

00:00:23.279 --> 00:00:31.840
pressure. Normal PC water cooling fittings, those are rated for about 8

00:00:28.720 --> 00:00:35.079
PSI. But if Jay's video is anything to

00:00:31.840 --> 00:00:37.840
go on, that's at 140 PSI.

00:00:35.079 --> 00:00:43.879
Oh, we think they might be able to handle a whole lot more. How much? Well,

00:00:41.760 --> 00:00:51.280
there's only one way to find out, courtesy of AMD, who sponsored this

00:00:48.120 --> 00:00:52.280
video. The Shiptorm sale event is live

00:01:03.199 --> 00:01:08.640
you've had your eye on. And we're featuring our lowest price ever on our

00:01:06.799 --> 00:01:14.080
magnetic cable management essentials bundle. Go check it out at the link down

00:01:10.560 --> 00:01:17.200
below. Woo! Yep, we bought a firetruck.

00:01:14.080 --> 00:01:20.560
All right, a pumper to be specific. But

00:01:17.200 --> 00:01:24.000
how hard does it pump? Well, we know it

00:01:20.560 --> 00:01:26.080
has an 8.3 L Cumins diesel engine, but

00:01:24.000 --> 00:01:30.479
these things came in all kinds of configurations, meaning that the exact

00:01:28.240 --> 00:01:36.400
power this engine makes, it's kind of hard to say, but somewhere between 240

00:01:33.840 --> 00:01:42.880
and 400 horsepower, which is good because under this console is a

00:01:39.799 --> 00:01:44.880
1,250 gall per minute pump, which is

00:01:42.880 --> 00:01:51.680
perfect because according to some rough maths from Alex, we need at least 240 40

00:01:49.200 --> 00:01:56.560
horsepower coming down this drive shaft to run that pump at its rated output.

00:01:54.720 --> 00:02:01.759
Now, I know what you're saying down there, typing, "Oh, my RAV 4 makes more

00:01:59.360 --> 00:02:06.640
power than that." Well, this diesel engine makes about four times the

00:02:04.000 --> 00:02:15.120
torque. Let's put into the context of a PC. A D5 pump makes about 0.03

00:02:10.479 --> 00:02:18.400
horsepower, 5.5 PSI, and is able to 6.6

00:02:15.120 --> 00:02:21.440
gall per minute. Our fire truck exceeds

00:02:18.400 --> 00:02:23.400
those numbers by anywhere from 36 times

00:02:21.440 --> 00:02:28.239
to a whopping 8,000 times, which kind of makes sense

00:02:26.879 --> 00:02:33.840
when you consider the difference in size, I guess. And as you saw in the

00:02:30.800 --> 00:02:36.400
intro, it results in a big difference in

00:02:33.840 --> 00:02:41.040
performance in the real world. With that said, as we learned when we built the

00:02:38.480 --> 00:02:45.840
maximum air flow PC, there's a law of diminishing returns when you add more

00:02:43.200 --> 00:02:51.760
coolant flow. So, we aren't actually 100% certain that our firetruck is going

00:02:48.720 --> 00:02:53.599
to meaningfully outperform our D5 here.

00:02:51.760 --> 00:02:59.040
I mean, we're pretty sure. We're just not 100% sure. We will soon, though,

00:02:56.959 --> 00:03:05.280
once I'm finished hooking this up. To adapt our fire hose to our PC, we've got

00:03:01.280 --> 00:03:07.360
this G82 BAT to 1/4in NPT adapter from

00:03:05.280 --> 00:03:12.000
Greenline. Shout out Jeff there, by the way. He had a wonderful LT store water

00:03:09.440 --> 00:03:15.680
bottle. Oh, that's pretty cool. Yeah, I just entered with a fire hose and he was

00:03:14.080 --> 00:03:19.360
like, "Please tell me you're not connecting that to a computer." And then

00:03:17.680 --> 00:03:23.120
sold me all the stuff to connect it to a computer. Nice. What a guy. It's easy to

00:03:21.840 --> 00:03:26.440
be a good mood when you're always refreshed and

00:03:24.840 --> 00:03:30.959
hydrated. ltstore.com. We're ready to go. Well,

00:03:29.120 --> 00:03:34.319
pressure gauge. We want to know how much we're actually putting into these

00:03:32.319 --> 00:03:39.360
things, right? Oh, and there is one other thing. AMD, our sponsor who made

00:03:36.720 --> 00:03:46.799
this video possible, kindly requested that we not unal alive any of their

00:03:41.680 --> 00:03:48.640
hardware. So, are we Oh, Oh, but

00:03:46.799 --> 00:03:52.799
on the first run, all this stuff is dead anyway.

00:03:50.120 --> 00:03:58.799
So, yeah, we'll find out how badly it's going to go here. Hey, AMD, great stuff

00:03:55.440 --> 00:04:01.760
though. Shout out AMD. Oh, yeah. Okay.

00:03:58.799 --> 00:04:05.360
This is terrifying. I mean, should we should we fire it out of this just to

00:04:03.200 --> 00:04:10.159
see what happens before we do that? Okay, that's a regular PC water cooling

00:04:08.000 --> 00:04:14.159
pump then. Now for the truck. Oh god, where are my glasses? On the subject of

00:04:12.159 --> 00:04:18.639
safety, never do what we did in our last video where we were quickly opening and

00:04:16.400 --> 00:04:22.639
closing the shut off valve. The sudden stoppage of flow can cause the pressure

00:04:20.239 --> 00:04:27.919
to spike potentially over 10 times the working pressure. Uh this can be helped

00:04:25.440 --> 00:04:31.440
with relief valves, but we don't have them. And also in firefighting

00:04:29.919 --> 00:04:35.440
situations, they normally don't bother with them because it takes too long to

00:04:33.520 --> 00:04:43.759
put it on. Also, we're going to get a bunch of electronics wet. So, we have a

00:04:37.840 --> 00:04:43.759
GFCI plug. Yeah. Good job, everyone.

00:04:44.600 --> 00:04:55.040
Woo. Okay. Okay. What's the pressure like? Okay. We have about like 70 PSI

00:04:51.840 --> 00:04:58.000
coming out of this hose.

00:04:55.040 --> 00:05:02.320
Okay. Another safety thing. Note that I like approached with caution. Really

00:05:00.560 --> 00:05:07.280
high water pressure can like rip your skin off. 80 PSI probably not so much,

00:05:05.120 --> 00:05:12.800
but still. Man, this thing wants to go. She's getting right snaky. Snaky? Yeah.

00:05:10.720 --> 00:05:19.520
What would happen if you let go? Do you want me to let go? I don't know. Sure.

00:05:15.120 --> 00:05:21.199
It's getting warm. Oh jeez.

00:05:19.520 --> 00:05:28.080
Wow. That's pretty funny. It's a good sprinkler system. Why is this water so

00:05:23.639 --> 00:05:30.000
hot? Are you noticing this? Feel this.

00:05:28.080 --> 00:05:34.720
Oh, wow. Okay, give her more. You want more?

00:05:32.720 --> 00:05:40.479
Yeah, I want more. I mean, what are we even here for if we don't do more?

00:05:37.759 --> 00:05:48.000
125. Okay, it's going up to like 150 nearly. Okay. Okay. 150. Okay. So,

00:05:44.639 --> 00:05:51.840
that's 150. Okay. Well, that's great.

00:05:48.000 --> 00:05:53.520
Okay. So, I'm going to close the valve.

00:05:51.840 --> 00:05:58.080
Okay. It's all fine. Okay. All right. Drop her down. Okay. Should we have face

00:05:55.759 --> 00:06:03.360
shields for this? I think it's fine. 200 PSI is a lot in computer, but hydraulic

00:06:01.680 --> 00:06:07.680
lines are like 3,000. That's when it starts actually getting scary. Okay. I'm

00:06:05.360 --> 00:06:11.680
just going to be out of line of sight of a fitting. I don't want a fitting in the

00:06:09.840 --> 00:06:15.039
teeth, you know. Okay. So, are we at about what the pump was doing before

00:06:13.280 --> 00:06:18.400
now? No, it's way more. Oh, that's way more. Okay. So, that's about that's

00:06:16.639 --> 00:06:22.880
probably about the pump. Oh my god. Yeah. Nears makes no difference. Zero.

00:06:20.319 --> 00:06:27.680
That's like five PSI. So, let's have a look at what would be double computer

00:06:25.520 --> 00:06:33.680
pressure. Okay. Yeah. Fine. About like so. Yeah. Doing great. Okay. Let's

00:06:30.000 --> 00:06:37.440
double that. Whoa. She's at about 40.

00:06:33.680 --> 00:06:40.160
All right. Okay. Okay. She's uh she's

00:06:37.440 --> 00:06:47.199
holding. She's holding steady. She's steady, boys. All right. Alex, give me

00:06:43.319 --> 00:06:48.960
100. 80.

00:06:47.199 --> 00:06:55.800
Wow. Okay, I'm going to start standing back. 90. I'm honestly surprised it still is

00:06:52.880 --> 00:07:02.440
just fine. 100. Is she going still? Yeah, it's

00:06:58.479 --> 00:07:05.080
fine. It's

00:07:02.440 --> 00:07:09.759
working. 125. Okay, we've been up to 125. And

00:07:08.160 --> 00:07:13.919
what would you be expecting to show signs of wear here? At this point, I was

00:07:11.919 --> 00:07:17.360
expecting the radiator to maybe bulging a bit or some of the fittings to be

00:07:15.440 --> 00:07:22.400
leaking. But well, on Jay's system, the reservoir detached from the pump. It was

00:07:19.360 --> 00:07:25.840
those acrylic uh threads that went, but

00:07:22.400 --> 00:07:28.479
this all seems to be fine. Yeah, besides

00:07:25.840 --> 00:07:32.960
all of it just shaking. Well, yeah. Aside from that, full

00:07:33.080 --> 00:07:39.919
150. I mean, this tube is a little bit.

00:07:36.880 --> 00:07:42.560
And she's rock hard, boys.

00:07:39.919 --> 00:07:48.240
The tubes are definitely a bit engorged. I was expecting this to let go by now.

00:07:44.560 --> 00:07:51.479
What the hell? Does it have more? has a

00:07:48.240 --> 00:07:51.479
lot more.

00:07:52.360 --> 00:08:03.759
170 175 200 PSI. Oh man, the fan spinning.

00:08:00.000 --> 00:08:05.840
What do you think that is from the pump?

00:08:03.759 --> 00:08:11.120
What? The pump I think is generating a bunch of electricity and powering the

00:08:08.479 --> 00:08:14.680
fan. What the? They're connected to the same molec.

00:08:13.120 --> 00:08:21.319
What the pump's plugged in here? Yeah, it's

00:08:17.759 --> 00:08:24.319
powering the pan.

00:08:21.319 --> 00:08:24.319
Okay.

00:08:31.000 --> 00:08:36.880
Jesus. Right at me. I knew we needed a

00:08:34.959 --> 00:08:39.880
blast. Oh, you got it, too. Yeah, I got it.

00:08:39.919 --> 00:08:50.000
One of these old bits power compression fittings finally partially let go. Now,

00:08:46.880 --> 00:08:51.680
one tricky thing is I didn't anticipate

00:08:50.000 --> 00:08:56.560
what this pressure was going to do to the water's temperature. It's getting

00:08:54.000 --> 00:09:00.080
hot. Water cooling with the fire hose. Feel it.

00:08:58.320 --> 00:09:05.440
Oh, yeah. It's pretty warm. May not be that effective, sir. But that won't stop

00:09:02.880 --> 00:09:09.600
us from trying it. Just like AMD won't stop making the world's best gaming

00:09:07.200 --> 00:09:14.880
CPUs, now it's time to kick things up a notch with our fully armed and

00:09:11.920 --> 00:09:20.240
operational gaming battle station. This thing has a 5800X in it. So very

00:09:17.920 --> 00:09:24.880
capable. Not the most modern thing, but yeah, what he said. And we really don't

00:09:22.240 --> 00:09:29.440
want to kill it, do we? No. That other system was very successful. But do you

00:09:27.519 --> 00:09:33.920
think these more modern, very fancy fittings will hold up the same? See, I

00:09:32.160 --> 00:09:39.120
actually have a theory that these more modern fittings might not hold up as

00:09:36.080 --> 00:09:40.560
well. Yeah, same. A, this tubing, while

00:09:39.120 --> 00:09:45.600
it's really good for preventing evaporation, is actually a little bit

00:09:42.399 --> 00:09:47.120
more slick on the outside. And B, I feel

00:09:45.600 --> 00:09:51.200
like a lot of water cooling manufacturers have gone away from those

00:09:49.360 --> 00:09:55.040
old school bits powers that were just raw, rugged clamping force, and they're

00:09:53.279 --> 00:09:58.959
more about the looks. Like, I don't know if this reservoir is going to hold

00:09:56.720 --> 00:10:03.200
Corsair. How's that even attached? Here's the thing. Just because our

00:10:00.800 --> 00:10:07.600
pressure gauge goes up to 200 PSI doesn't mean that that's where our fire

00:10:04.800 --> 00:10:15.320
truck stops. Alex, what'll she do? I think it'll go up to 400. Let me check.

00:10:11.600 --> 00:10:18.680
So, we're putting a blast shield in

00:10:15.320 --> 00:10:21.279
place. Well, it is

00:10:18.680 --> 00:10:25.040
bright. It's just that the blacks are also

00:10:22.440 --> 00:10:30.880
bright. Like probably brighter than most other monitors that we use.

00:10:27.440 --> 00:10:34.560
We're getting about 46 to 47° on the GPU

00:10:30.880 --> 00:10:36.320
and about 6263 on the CPU. Let's see

00:10:34.560 --> 00:10:40.079
what happens when we dramatically increase our water flow. This may be the

00:10:38.480 --> 00:10:43.839
most pointless thing we've ever done. Are we just leaving this system running

00:10:41.600 --> 00:10:47.040
and just swapping the coolant live? I guess so. I mean, the valve is closed on

00:10:45.680 --> 00:10:51.240
this. So, theoretically, you just open her and we're good to go for the beans.

00:10:51.760 --> 00:10:59.760
Woo! Give me 150. You want one? You want to start at 150? Yeah, cuz I can adjust

00:10:57.440 --> 00:11:05.000
it with the valve. How's our tent? Okay. Very high. Oh,

00:11:01.480 --> 00:11:10.640
god. Okay, here comes some water,

00:11:05.000 --> 00:11:12.880
boys. Okay. All right. We're now at 36°.

00:11:10.640 --> 00:11:18.079
Okay. So, temps are good. Okay. So, here's pretty typical water cooling, you

00:11:15.519 --> 00:11:25.440
know, flow. Uh well, this is a little on the high side. We're at about uh 10

00:11:21.640 --> 00:11:26.880
PSI. Oh my god, why am I back here?

00:11:25.440 --> 00:11:32.640
Literally, what is the point of a blast shield if I am behind

00:11:29.000 --> 00:11:34.399
it? Okay. All right. There's 50. Oh

00:11:32.640 --> 00:11:38.480
jeez. She's leaking. Can I get a zip tie? She's leaking. She's What? She's

00:11:36.399 --> 00:11:44.240
leaking. What do you mean she's leaking already? Yeah. What a piece of crap.

00:11:42.720 --> 00:11:47.279
Okay, that's at least partially our fault for leaving a plastic fitting in

00:11:45.760 --> 00:11:53.839
here. Is that where it leaked? Yeah, from there. Oh, this piece piece of

00:11:50.720 --> 00:11:55.360
first gen Corsair water blocks. I

00:11:53.839 --> 00:12:00.240
remember calling them out on this and they were like, "No, no, it's really good." And I was like, "No, it's not."

00:11:58.959 --> 00:12:06.839
And they were like, "We felt you were very unfair." And I was like, "No, I wasn't. Let's go get the emergency just

00:12:04.240 --> 00:12:10.600
in case we need a more hardcore machine machine." We'll let this thing dry out.

00:12:09.040 --> 00:12:18.440
It should be fine, by the way. Should be fine. Meet Big Bertha. Oh god, we used a

00:12:14.560 --> 00:12:21.120
Corsair block again. Oh jeez, we

00:12:18.440 --> 00:12:25.440
did. That might be bad. You can really see that other than that Corsair block,

00:12:23.519 --> 00:12:29.760
uh, which might be better. It is a newer one.

00:12:26.600 --> 00:12:32.079
Um, this is pretty robust. We're using

00:12:29.760 --> 00:12:35.839
pressure rated hose this time. We're using server barbs that are generally

00:12:34.079 --> 00:12:39.680
designed to have hose clamps on them. And then we're using Yeah, there you go.

00:12:37.760 --> 00:12:43.440
And we're using worm drive hose clamps because working with these ones is kind

00:12:41.680 --> 00:12:47.920
of a pain. The best thing about this system, though, is probably going to be

00:12:45.200 --> 00:12:54.399
that flow meter. That thing's gonna be

00:12:50.920 --> 00:12:58.160
going. There's the new one. And that

00:12:54.399 --> 00:13:00.600
looks a fair bit more robust. Oh, my

00:12:58.160 --> 00:13:06.680
confidence level just went up 100 PSI. Hey, let me know when you're

00:13:04.600 --> 00:13:10.000
ready. We're ready to

00:13:10.120 --> 00:13:14.720
slow. This scares me every time. We

00:13:13.200 --> 00:13:18.560
pulled out the radiator. Had a little issue there, but now we're good to go.

00:13:16.560 --> 00:13:22.000
Oh, we got our flow meter and let's get our screen cap set up and get this thing

00:13:20.160 --> 00:13:26.720
running. I feel good about this. On the CPU, we've got an all metal block. So,

00:13:25.279 --> 00:13:30.639
that means the screws on the underside are threaded right into metal. And on

00:13:28.560 --> 00:13:35.200
the GPU, we've got an acrylic block. But man, this is one of the thuggest looking

00:13:33.360 --> 00:13:38.200
acrylic blocks I've ever seen. It's so thick.

00:13:40.800 --> 00:13:47.519
We have a different GPU now, so it's not an applesto apples comparison, but this

00:13:44.880 --> 00:13:56.800
is a 450 watt GPU, and it's currently running at uh about 60°.

00:13:51.959 --> 00:13:59.440
Okay, 100 PSI. Oh my goodness. You can't

00:13:56.800 --> 00:14:07.600
even see the blades moving in this flow monitor. It's just a blur. We're at

00:14:03.440 --> 00:14:10.399
freaking 35° on the GPU. See, the die on

00:14:07.600 --> 00:14:16.320
the GPU is so big that your bottleneck for thermal transfer actually is the

00:14:13.760 --> 00:14:20.880
block to the coolant rather than the die to the block. Like you see the CPU

00:14:18.079 --> 00:14:25.959
stopped going down. We're at 42. I mean, it went down a little, but we can bring

00:14:23.279 --> 00:14:32.519
this GPU down to damn near the ambient temperature just by hooking our PC up to

00:14:28.720 --> 00:14:37.480
a truck. That's all you had to do.

00:14:32.519 --> 00:14:42.399
Wow, it seems so obvious now.

00:14:37.480 --> 00:14:46.880
Woo! Let's go. All right. 150. How we

00:14:42.399 --> 00:14:49.320
doing, brother? Is our GPU at 26°?

00:14:46.880 --> 00:14:54.880
I had Alex put some fresh water in the tank. This may have thrown our results

00:14:51.920 --> 00:14:59.839
off a little bit, but my god, it's working good. And yet, the CPU is still

00:14:57.920 --> 00:15:04.320
locked. 33° is not what I would consider lock.

00:15:02.639 --> 00:15:07.920
Oh, I mean, yeah, that's fair. That's fair.

00:15:05.760 --> 00:15:12.720
Whoa. Is the tubing starting to bulge? Are things leaking? Holy crap. I think

00:15:10.320 --> 00:15:18.240
things are leaking. It's like dripping. Where is it leaking?

00:15:15.360 --> 00:15:26.120
Oh crap. The GPU block is leaking. Wait, the GPU block?

00:15:21.160 --> 00:15:29.519
Yeah. Is it Bode? I think it's Bow,

00:15:26.120 --> 00:15:31.360
Alex. Whoa, buddy. Yeah, you can see it.

00:15:29.519 --> 00:15:35.920
Yeah, it's bode. I mean, I guess that's what 150 PSI will do for you. At this

00:15:34.560 --> 00:15:42.000
point, do you just turn off the system and see what you'll take?

00:15:38.680 --> 00:15:46.160
No. The people came here to see it run.

00:15:42.000 --> 00:15:50.800
Let's see what temps we can get. 200.

00:15:46.160 --> 00:15:53.279
200. It's at 200, boys. Oh my god. The

00:15:50.800 --> 00:15:58.240
GPU looks okay now. Wait, it didn't even go down anymore.

00:15:55.680 --> 00:16:02.480
At 30C. Yeah, that's probably just the temperature of the water. Yeah, the

00:16:00.079 --> 00:16:07.199
temperature is going up. Also, the GPU blocking might have something to do with

00:16:04.639 --> 00:16:12.000
it. Oh, I wonder if it's not flowing through the fins as much.

00:16:10.079 --> 00:16:15.880
It's probably shortcutting this impinchment jet. That makes sense, dude.

00:16:15.040 --> 00:16:19.920
That's crazy. 250. Let's

00:16:20.360 --> 00:16:28.320
go. My gauge only goes to 200,

00:16:25.639 --> 00:16:34.680
so I'm just going to open her up. Alex says it's at 250. I'm gonna hope this

00:16:30.800 --> 00:16:34.680
gauge doesn't blow up.

00:16:36.160 --> 00:16:44.040
Oh, it's leaking a lot. What?

00:16:40.240 --> 00:16:44.040
Oh

00:16:52.880 --> 00:17:00.880
Did you kill the computer? Woo.

00:16:57.199 --> 00:17:03.440
Oh wow, she failed hard. Okay, to be

00:17:00.880 --> 00:17:08.079
clear, we're not criticizing EK. Not for this anyway. I mean, we were well over

00:17:05.360 --> 00:17:11.360
200 PSI. Probably like 230, 235. I didn't have it open all the way yet. And

00:17:09.760 --> 00:17:14.559
also like our gauge doesn't go that high anyway. Yeah. So, we're guessing. We're

00:17:12.959 --> 00:17:18.079
guessing. We're flying blind. I guess bottom line, it's just a matter of the

00:17:16.000 --> 00:17:21.280
materials and surface area, which you know what? That other one that had like

00:17:19.679 --> 00:17:28.000
twice as thick acrylic probably would have done better. The issue was just that that car ended up not working. So,

00:17:25.600 --> 00:17:33.880
dude, and the metal CPU block didn't give any cares. And this thicker acrylic

00:17:30.799 --> 00:17:36.400
flow meter, dude, this thing cared about

00:17:33.880 --> 00:17:41.039
nothing. I think part of it is that the screws on this one are secured into

00:17:38.160 --> 00:17:46.000
metal into a metal face plate. So, that probably helps quite a lot. Just like it

00:17:43.840 --> 00:17:54.160
helps to tell you about our sponsor. I mean, AMD. Oh, yeah. Right. AMD. Hey.

00:17:49.360 --> 00:17:56.080
Hey. The AMD CPU did fine and survived

00:17:54.160 --> 00:18:00.080
probably. If you guys enjoyed the vibe of this video, you might like the one

00:17:57.440 --> 00:18:05.440
where we hooked up an array of uh lithium polymer batteries to this like

00:18:02.480 --> 00:18:10.559
bizarre turbine fan. And you might also enjoy checking out our sponsor AMD. Uh

00:18:08.080 --> 00:18:17.120
Alex actually, I know, right? Just switched over to the Ryzen AI Max. What

00:18:12.960 --> 00:18:20.799
is it? The 395. Max Plus Pro 395. This

00:18:17.120 --> 00:18:22.880
thing is sick. It's insane. Like

00:18:20.799 --> 00:18:29.919
investment disclosure and framework, but damn, this ebook. Damn, it's so good. Go

00:18:27.520 --> 00:18:29.919
AMD.
