Recently, with the help of one of the world's top overclockers, we built the
world's fastest gaming PC, cracking the top 20 on the 3D Mark leaderboards. And
that was all without doing anything particularly horrible to our RTX 5090,
which got us thinking, what if we did do horrible things? There it goes. See? Oh
my god. Got to say, boys, I was expecting the
wicked fast test bench. I was expecting the chunky water block. And I was
expecting the industrial chiller. What I wasn't expecting was for you to put
Blasty Dip all over this ASUS ROG Astral
GPU. Why? Sorry. Go fast.
Well, that's the thing, isn't it? If we want to go fast, we got to go cold. And
if we want to go cold, there is a very real risk of condensation forming on our
components. Now, we could insulate them, but realistically, we probably don't
need to because inside our environmental chamber, we can control not only
temperatures, but also humidity. meaning that we probably won't even need our
makeshift conformal coding. It just looks cool, just like I think it's cool
to tell you about our sponsor, Hner. Hster is based in Germany and has your
data locked down by GDPR and strict privacy laws, even at their locations in
the US and Singapore. Get $20 off a Hexner cloud server today using code
LT25 at our link in the video description. If you don't get why NVIDIA
would care about what we're doing, I don't blame you. I mean, it's our GPU,
and I'm sure that they would agree that we can paint it as we see fit. But what
NVIDIA doesn't like is when users and board partners play around with the
power targets for their cards. And this particular one is running a BIOS that
allows us to run it at over a,000 watts.
That is about double of what the excellent 12vt
2x6 power connector here is rated for.
Not only that, but even with this special hybrid liquid metal compound
that SPL provided for us, running 1,000
watts through this GPU could have a serious impact on its reliability and
being aliveness, which NVIDIA doesn't like. This is cool. I was cleaning off
the hybrid compound for a B-roll shot, and you can actually see the little
balls of metal in it. It's where my nickname comes from.
We've already done a baseline run with our card on air cooling. So, our first
step is to install this Bits Power Nebula GPU.
Wow. Damn, that's beautiful. I don't
know about you guys, but uh I'm going to need a cold shower after after seeing
these machining marks. I'm going to install this on there and then we're
going to do a non-chilled water cooling run to see if we can push things any
further than we already have. What's this block go for? It's pre-production,
so we don't really know yet. Probably around 250. enough that if you can
afford a 5090, you don't care anyway.
All right, let's see how it goes. Now, quick question for you. For your hybrid
liquid metal thermal compound to work properly, do we need to run this at an
above ambient temperature for a little bit? Let that liquid metal melt and
spread out. I would say it couldn't hurt anything. Okay, it's not
Don't show that. No, no, no. Don't show that. NVIDIA really never is going to
send us a GPU ever again. Do you want to take that GPU out? Why? Well, we're
going to take it down anyway, and you're going to spill water on it. There's a stop fitting here, right? So, should be
fine. Did you stop the other stop fitting? I did. Cool. Man, Bits Power
makes some gorgeous stuff. I still remember their OG true gold and true
silver fittings back in the day. The silver ones were brilliant, actually,
because they serve a dual purpose. They look cool and silver acts as a natural
bioside, so you don't have to worry about anything growing in your loop. Wow, these have a lot of restriction in
them. Can't say I love these fittings. Spits power. Also, the threading is not
good. These cards sag enough when you do have them screwed in at the back. This
one's on a whole other level. Like, I cannot I cannot let go of this. It will
probably break the socket off. Oh, wow. It's got all the sizes and everything.
Look at that. Comes with your own calipers. Perfect.
Alex was saying I went too short on this tube, which could be perceived as dumb.
Like a fox. Now, it's a safety net for our our poor GPU in case the SEG bracket
gets bumped. Now we theoretically open up the valves and everything is bueno.
What could go wrong? We couldn't figure out why the GPU is at 0 degrees. It's
because of zero zero deg zero frequency hertz. Yeah. Frequency. That unit of
measurement that everyone uses and such. All right. This does not look any faster
than yesterday. In fact, it looks slower. Yes. You didn't overclock anything, did you? No. I knew we brought
you here for a reason. I want to make sure it's working first. Is that 58°
though? That doesn't seem right. Before we push things any further, Alex wanted
to compare this score with what we got on our stock 5090, which is
actually I don't think this is the right BIOS. But what do you mean by not the
right Oh, we hit 970 W. Okay, I'm giving
myself some credit here. Remember when I was like, "Hey, those temps seem high."
I remember that. I I remember. Do you want to go back to the normal BIOS? I
feel like now that we've skipped the regular BIOS, we've skipped it. So, we
might as well just go for it. plow forward. Yeah. So, now we could probably
make some adjustments to clock speed. Yeah, absolutely. The idea today is to
crack top 10. We haven't even pulled out the chiller yet, and we're already well,
we're not that close, but we'll get there. Just to be clear, none of what
we're doing is necessary or probably even going to result in a difference
that you would feel dayto-day. This is pretty much as fast as hardware gets as
it is. We have a Ryzen 9 9950X 3D processor, which is as fast as it gets
with eight of the cores having 3D vcash and the other eight cores to pick up, I
guess, any slack. We have 32 gigs of DDR5 6000 CL26 and that's tuned to run
at about 6200 MHz. And of course, we have an Astral RTX 5090, which according
to Splave is the best one. Yeah. Most importantly though, it's in a
Lamborghini case that'll make it go way faster. Alex, you see this carbon fiber?
That's plus like 25 FPS for sure. I'm willing to bet it doesn't even affect
the like weight of it that much. Oh, it's a really heavy game. God, it's so
heavy. I bet you could lift it easily. Maybe.
Sorry. Now that I know this thing's running a 1000 watts, I'm really impressed with this water block rather
than disappointed. That's a lot of heat. How much radiator
you got on this? Just a triple. Yep. That's a good thing we're going to be
replacing that. Bits power did not give a thermal pad. I was just checking that.
No, they didn't. I would strongly recommend Bits Power if you're watching
this or if you buy one of these and Bits Power didn't watch this. Throw a little
thermal pad right in the back by where the GPU power connector is. It might
help dissipate some heat if you ever have a loose connection. Now, that's totally cheating. You just set the
anisotropic filtering to crap mode. High performance, baby. They used to call
that cheating. Doesn't have to look good. Just has to be fast. Well, in
fairness, the reason they used to call it cheating was because ATI and NVIDIA
would change it around in their defaults in the driver settings. That's true.
It's fine if I decide I want my image quality to be a little worse. It's not
fine if you decide it should be worse. This looks pretty good. Ah, we cracked
it like 210 there. Oh, yeah. What did we even do? Uh, we just bumped the clock
speed up a little bit. Nice. This legit looks like a really good run. I don't
know about top 10, but good run. We just have to beat Jake. Oh. Easy. Whoa,
buddy. What was JC at? Yeah. 4325. I think
we're 43129. All right, we can do better. Oh, we're not there. 43250.
Let's chill it. Chill it. Yeah, let's not just break him. Let's crush him. Uh,
do you want to do a quick explainer for those who didn't watch the previous video? You know, what all these dials
and knobs mean and what order you should adjust them in. In the meantime, I'm
going to go plug in the chiller. So, the first thing you do clearly is set the
fan speed to 100%. Doesn't matter on our
card, but on yours it probably does. After that, I see you have the power
target only at 95 and have done nothing to the GPU voltage. Would you want to
play with those at all? At home, probably. If you don't have the 1000
watt BIOS, um you're you're going to run
into thermal problems before you hit 100%. At home, you would maybe even use
I think it goes up to like 104 or 105 on a normal card. You just max that out.
Then you could play with the voltage a little bit. Uh and then just I just do
25 megahertz at a time uh on the clock
and run it and if it passes go higher. Easy enough. Easy. The voltage is tricky
on 5090. It gives you a percentage. What
does that mean? I just put it at 100%. Okay. All the volts. 100% voltage. Sure.
And you can see that doesn't really affect much. It caps itself out. They
don't really want you to increase voltage on the card when power limit is
kind of the limiting factor. Makes sense. So we're kind of controlling
power only through power target. So you
can use VF curve to to lower voltage
but the performance is worse. I just avoid messing with voltages and just
play with power target and your core clock. So if it becomes unstable when
you go a tiny bit higher in the boost, you increase the power until you max it
out. Yeah. So say I have increased the
GPU boost clock by 200 MHz and this
failed. So you could try like 95% power
target and see if you pass.
And if you pass, that's about all you get. Would you ever
turn down the power target and try again and see if it was a thermal issue? Uh,
you could turn down power target, but then it's just going to take away your
clock cuz you'll hit the power target cuz Jake says he backed off voltage and
that was how he beat us yesterday. We run the air conditioner
so we would by the end of the run it was the card was really warm whereas here
we're taking the heat away and it's not really going up after we've started the
bench. I see. So, by the end of the bench, we were failing maybe in the last
2 seconds. So, we just really need like 3° to be able to pass. Okay. I got a lot
more than 3° for you. Our chiller's ready. All right. Let's do it. All right. Let's do it. Did you have kind of
a a thought on exactly how we're plumbing this up? I was going to close
these and then just remove a couple of
PCIe brackets, throw them at the back. Oh, okay. Do they just go to the back or
they could just go here? They just go right there, too.
I don't think we need the reservoir on the loop either. I was just going to plum around it. I was basically just
going to go to like here. Oh yeah, we can just totally delete the whole
radiator if you want. What do you need a radiator for? Radiators are for chumps.
Yeah, we've got a much bigger one. Hey, there's a display for coolant temperature in there. Is that what that
is? Yeah. Oh, sick. Does it go sub-zero? We don't know yet. Oh, neat. Okay, we'll
find out. Cool. The last thing that I want to do is drain this reservoir
because if we go and we put this in a sub-zero chamber and it freezes, it will
break. It's about to get real, Alex. Oh, Jesus.
There it goes. See, that's the fastest way to drain a thing. This is really
nice how Le and Lee did this. You just push on that. Full thing comes out,
buddy. That's awesome. It's full of water. Don't forget. Yeah, I know. Cool. Okay.
I'm just making sure, you know, before you like, you know, spill water. I'd hate for any of that to happen on this
shoot. It's been a really tidy, clean shoot with my spilled water so far.
There it goes. Professionals. All right, let's fire up this chiller. All right.
All right. Let's go.
Woo! She stopped pumping. I'm just going to give her the old power cycle here.
Also, that poor pump sounds like it is dying. She moved a little bit of
coolant. And then she stopped. That seems to be full of coolant. Yeah, we
must try again. Okay, we're just trying again. Not going
to lie, little scared. That sounds pretty bad. We might need to prime the
pump, Alex. We shouldn't have to. I mean, I know we shouldn't have to, but
we might want to do it. That is super weird. Why? What are you adjusting?
Oh, this is the pressure. Oh, Jesus.
I got shelled.
I was going to say we should put some hose clamps on those and then I totally forgot. I brought them over. Oh my god,
it's a mess. Is deer toxic? Um, it's all
over me. It's probably not great for my pants, that's for sure.
We're supposed to cool the computer, Alex, not the people. Look at the
screen. Oh no. And this video had so many fun moments
that we couldn't fit them all in this video. So the extras are all on float
plane. Go check it out. Oh, he doesn't see me. He doesn't see me. He doesn't seem No, no, no, no. Come on. First you
call me small balls. Then you say you don't believe in my ability to install a
water block. Alex, were we reading it wrong? Yeah, we're just really dumb. Oh,
this is peak cinema. Fortunately, the
glass panel in the front of this computer took the brunt of it. I don't
think we hit the GPU or motherboard. One drop right there. We hit our screen in
the back, but I think she's pretty clean. Okay, so she was clearly moving
it. Yeah. So, that was awesome. This was
air log. Yeah. Is there a valve shut off
somewhere else? because it seemed like it was pushing against.
Yeah, because that's the out. Oh man. Dude, I am super confused. Oh my god, I
figured it out. Oh, we're idiots. The
shut off. We had the valve closed on the
CPU block. We're lucky we didn't blow up that GPU block. Yeah, it would have been
fine. We They're good for over 200 PSI. That's true. We do. Well, not that one
specifically, but pump only does like 100 PSI. Our Canadian healthcare doesn't
cover your chemical brand. I'm sorry. Yeah, I probably have better coverage here than I do at home. Okay, let's do
this thing. You ready?
I guess it's Oh my god. Oh my god.
All right, we did it. Is there overclocking always this as exciting?
Not as explosive as this usually. What do we think is safe to set the chiller
at? Right now it's at 23. Yeah, lower. I bet we could do like probably 12 or so.
Yeah, I was going to say 12. All right, give her a sec. She's chilling. She's just chilling, you know, jumping right
into a benchmark. Already, I think we're what, 5 degrees cooler than we were when
we were relying on ambient air to cool our loop down. Exactly. And did you
change any settings or anything or we just hoping it's going to more clocks?
Okay. We're still on the 1000 watt BIOS. Hey. Yeah. And we're at 43°. Yeah. Wow.
So, it was really heating up that water before. Well, I think the bigger thing
now is that the pump just is ripping compared to the 85.
43810. There we go. All right. Wa,
buddy. Okay, let's submit that, buddy. LT right here. Let's go. Number 17. Take
that, Jake. Honestly, though, um, Alex, she's struggling to pull down. Yeah.
What's on the go? Well, 1,000 watts of GPU. Oh, that that is a thing. Like,
does this not have 1,000 W of capacity? It has 5,000 watts. Oh, well, on the one
hand, we're pretty upset about our industrial chiller not working. We think
maybe there's been a gas leak of some sort cuz she's pulling down. The
compressor is running, but the condenser
is not hot and it's not pulling down to
the temperature quickly and it's actually going up while we run our benchmark. The good news is that we just
hit 44,000. So, is that still 17th
place? 16th. Oh, wait. We We took your
own spot. Ah, normally I'd be thinking, okay,
we'll just get an HVAC technician to come out and fix our system. But the
problem is that Allan's got a flight to catch. So, if we want to go very, very
subzero, we're going to have to come up with some ideas. Hey, look. I found an
idea. Oh, yeah. Now, that's a radiator.
We throw this with a bunch of high-speed fans inside the environmental chamber,
and we can chill the loop down that way. Ooh. Ooh, that's pretty fast. spicy.
Even though the chiller isn't chilling quite as well as we hoped, the pump in
it is still fantastic, and our scores just keep on going up. I'm trying to
find 3,000 RPM fans, but they're all mixed in together with the 2,000 RPM
fans. Hello.
Huh. Yeah, that'll do nicely. Here's
what I'm kind of vibing, huh? All right, I got a plan.
What are you doing? I am making a shroud. Why? Because if we just put the
fan against the radiator, we're going to miss out on probably a solid 60% of the
actual cooling capacity of that radiator. Dude, this is going to be
awesome. Heck yeah. Oh, dude. See this?
This is what I'm talking about. Okay, so we get the fan off of the fins. Boom.
We're making use of all that airflow. Boom. Oh, I wish I'd centered it. Well,
it's done now. So, this is going to be sketchy.
Shield your virgin eyes.
Gorgeous. All right. So, now theoretically
all the airflow will go through the radiator. We have a
cooling solution. Side quest complete. You have obtained this freaking thing.
Okay, here we go, boys. Oh my god. What the hell is that? That Oh my god, my
friend is a radiator and a fan. Whoa,
buddy. Oh, that's fast. We're working. We're working over here. I was working.
What are you implying? I made this. That's beautiful. Oh, wait. Did I ever
get a pump? Okay. Well, I found a reservoir. So, we have that. Well, what
I was thinking was we still use the chiller even though it's not chilling too good. That pump in it is insane.
Okay. So, we put the chiller back. Are we going to lose a lot of our cooling,
though? Maybe use the res pump thing we were using in here or No.
Yeah, we could just use that one. We could do that. Yeah. So, wait, wait,
wait, wait, wait. Where does this put us? Oh, dude. Let's go. Let's go. We're
top 10, baby. Let's go. Not even cold yet, right? In terms of raw actual
numbers, we're not even that far off some of these scores. Yeah. Do you think
she's got more left to give? I think she does. All right. I'm excited.
She's still spooling. Wow. That is So, I think she's going to cool your uh your
GPU there. Uh I think we're good. So, we're just going to use this and we're
just going to set it up in there. Woo! She's chilly, boys. She's chilly. So,
it's blows out here. I feel like we could do that.
Okay, I'm going to run the power out to Alex.
All right. How we feeling about this? Uh, mid. We call that a Canadian W.
Feeling mid. Okay. Here we go. Wait, should we take the tempered glass off?
No, I just throw it in. Okay. Oh, yeah, bud. No problem, bud. Okay, so we got
the radiator here. Love the O1 case.
It's designed so you can reach right through it when you want to get to your
janky subzero water cooling radiator in
your environmental chamber like that. See, bud? She goes into the radiator, up
the top of the radiator, down to the GPU. These are stoppered. Uh, then we
got this here. Uh, there's some tubing.
And then if you want to give me like a cable tie or something, then we can come
off it here. Never grow up. You just get better toys. Let's get some windshield
deicers. We don't have a funnel by any chance, do we? Man, I really hope that
this doesn't le That's good. We're going to need another bag, I think. All right,
Alex, you want to power cycle it? Dude, the coolant said 16 and that's with the
door open. Reese, are you hitting the fan? Yeah, go for it. And this is how
you set records, I guess. Well, depends. We haven't gotten there yet. Hey, we got
a great view of all the displays and everything. So, our coolant is at 8° and
our GPU is at 12. That actually checks out. That sounds about right that at
idle, our GPU would be a few degrees above our coolant temperature. We're
gonna see that delta grow once we're actually running benchmarks and stuff.
But, uh, this is a very good starting point. You know which delta I'm actually
most impressed by how close our coolant
is to the chamber temperature. Yeah, it is really close. 2° off. That's how much
air we're moving through that radiator. Fear it. How's them temps? You like them
temps? Temps. They seem okay. We're at minus.5 and our loop's at 4°. GPU
sitting chilly at six. This worked surprisingly well given that our chiller
stopped chilling. I can't believe we pulled this solution out of our butts.
Okay, so we're at 30C on our GPU right now. She's running pretty smooth right
now. Eh, 45 349.
We're in seventh. Seventh. That is a
whole gigahertz over the base of like a founders edition. And it didn't even
take very much work, did it? Just for
me. Whoa. This is going to be a pretty nice
run, I think. So, yeah, we haven't even failed yet. Really? Oh. Oh, shouldn't
have said anything. Why did you say that? Did you see that? Why did you say
that? We've been finding that the 50 series does this really weird thing
where when the load drops, like you're not hitting it 100%. The frequency just
goes to the moon for some reason and then it crashes. 45 354. That is a touch
higher, isn't it? Five points. Yeah. Okay. Hey, look, I'll take it. So, you
don't think that giving the CPU anymore will get us any more score? Probably
not. Um, Intel actually scores a lot higher on
this 1400 series for some reason. Oh,
did we? So, we if we would have used one, it would probably
Sorry. This is what we get for building a computer that's actually for gaming
instead of for getting higher benchmark scores. Exactly. Oh,
that is fast. Oh, six. We're going for
number six. Let's go, baby. Let's go. Top five. Actually, we're the top AMD
result now. Top AMD. Top Canadian. Let's go. All right. How much is this drawing?
Oh, it's it's not too crazy. 900 watts
at the moment. Okay. 1,028. 1,000 and a
bit. That's about what we expect. That's what we were doing before. Here we go. I
believe. Come on. We're just shy of minus 20 on the chamber. We don't want
to go too much lower than that. Once you start hitting minus30, um things don't
likey. That's what like the juice in the capacitors of your power supply just
starts turning into solid not juice.
She's artifacting. Nah, she's artifacting.
That's a fun one. Oh wow, we're starting to get some really weird reported
numbers there. Well, our RAM's on the sun, so that's probably going to be a
problem. You ever feel like if you don't move, it'll pass? Yeah.
No, she us. I kind of almost just want
to restart the computer and see if that helps it. Okay. It seems to be a bit
confused. I like it. What makes this a Hail Mary
run exactly? Uh, I don't even know what I said, so we'll just see if it works.
What do we need? Like 50 points, something like that. Yeah. Yeah. Not
much. Always the last 50. We're at our full minus 25 now. So, there's nothing
more we're going to get from more cooling. Like, we've kind of been changing multiple variables as we've
gone here because we've been adding more cooling capacity as we've been tuning
it. Kind of building the train as it's flying down the rails. Come on. Oh,
is that enough, boys? Wa. Now, that's a Hail Mary if I've ever seen one. Is that
her name? The astronaut. Mary. What? Katy Perry. No, it's Mary. 45. Fourth.
Number four. We're top five. Let's go. Let's go, Canada. Let's go. Damn. And
these are LN2 scores. Really? Yeah. We went faster than Len. Yeah, man. Why
were we able to beat an LN2 rig? Yeah.
With a processor that really is not as optimized for this benchmark. What did
we do right? So, what could the people do? They're using a D2. I think is maybe
slightly less performance. Got it. But I
think the cards might shut off at like minus 40. So we're almost there, I
guess, cooling wise. Understood. That makes sense. So do you think if we
had a 14900 in here that we would have a shot at top three podium finish? That's
500 more points. That's a lot. Uh so I
talked to Safe Disc and he said he tested it and you it was about a
thousand more points. So, we maybe would
have been up top here. I'm sorry.
I'll go home and do that. Okay. Okay. I'll send you the chamber. Yeah.
That's a nice card you've got yourself there. Not bad. She seems She seems
pretty binned. It looks like you might have a shot at number one with that thing. Are we happy with this? I'm
really happy. Yeah, that was great. Like, we're as we're as high as we're going to get. We squeakaked past Ralph.
Squeakaked past. It's a really fast computer. Should we game on it? Be kind
of silly if we didn't. What's the cost of the system plus the chiller?
That's not a bad title. 50k gaming PC.
Yeah. How fast is a $50,000 gaming PC? Never mind that most of it is not the
PC. I can't believe we hit top five. Let's go. Never doubted it.
Just we were getting ready to pack up. That's
why he's so big, cuz he's full of
Can I win Counter Strike now? Oh yeah, there we go. There we go. Oh. Oh, now
we're going. We're going fast, boys. Got him. Got him. Look how fast that kill
was.
Damn it. Wait, our FPS isn't even that good. Oh, wait. We're at 1440p.
Yeah, she doesn't look that bad. Let's go. Head shot. Boom.
Damn it.
Oh, how can I miss all three of those shots? And he ain't even a pro. Maybe
his computer's in a giant freezer, too.
That's probably it. He probably out freezered me.
Hopeless. God, I missed that. Come on. Good
movement. Good movement. All right. Come on.
I give up. Uh, Oblivion Remastered. Here we go, boys. Okay, we're running at a
casual 560 frames per second.
Oh, no, no, no, no. She's good. She's good. No, I don't think it's good. Oh,
she's not good. Uh, she's not good. She Oh, she's bad. That's a wrap.
