So since we've made it past the 900 k launch and the 2700 launch, there's not really anything else coming up that I know is We can kind of get back to this because I just started getting my feet wet, huh?

No pun intended, but let me feel what I did it really wrong, but discarded started with x o.

C.

I haven't touched anything like this since I did my Ellen to over clocking video with King Pin.

Where?

Let's face it, he said everything up and I just sort of got toe pour the Ln to which was fun and all, but yeah.

So you guys saw the live stream.

Maybe you didn't accept over 150,000 replays on the Lifestream, which is crazy.

I'm gonna show you guys today kind of the process of doing dry ice cooling.

Not quite as exotic as Ellen to, in my opinion, a lot more dangerous because of condensation.

In fact, I already killed one of our ex to 99 dark motherboards.

So let's just hope that doesn't happen today.

Vengeance are to be pro DDR four memory from Corsair features optimized peak performance for both the latest Intel and a MD based DDR four motherboards.

To learn how to bring your computer memory to the next level, click the link in the description below.

So obviously, you're gonna need a motherboard.

Any processor that could be anything you want in terms of over clocking.

Obviously, we've chosen the 18 course 79 80 XY because where you're going for you obviously ripped Jen and Rip Paul and all that, So the bigger, the better.

And, yeah, you need a good motherboard designed for over clocking.

So the X to 99 dark is designed specifically for that reason.

That's why we're using that.

We're also using G skill Trident Si non RGB memory.

This is also 3600 dims because memory plays a huge part in our three D mark scores, especially when it comes to physics.

So that's why we're using gays.

But obviously you need a way to keep things cool.

Now this is the pot that I was using.

This is technically an Ellen to pot is the one team pin left behind.

If you guys haven't seen that video going, watch out trying to put a link down below.

Now the scores I recently got, he said.

Uh, hey, not bad that you got those scores on dry ice and the fact that you did it on a pot that's not designed for an 18 core.

So he just sent me his newest pot design for 18 core, and you can tell by looking at it.

It's obviously a lot bigger things.

One's a two piece to get different colors and stuff on it.

But if we look at the inside, you can see just how much more tower there is our individual chambers for cooling to kind of more control the actual base of the pot to give us a good cooling service area so you can see the whole thing is definitely designed for 18 Corp.

Which is exactly why he's like, Hey, you want this pot?

He also sent This is kingpin cooling heater plate now already killed a motherboard, like I said, and the reason why I killed it was condensation.

I let it get too warm.

Condensation formed garden into the PCB, and I believe it actually got into the socket and it killed the motherboard, but not the CPU.

It's amazing how robust the CPU is.

This CPU just keeps on tickin, so we're gonna see how far we can push it today.

But this actually goes on the back side of the motherboard.

It uses one of these giant thermal pads that he sent with this.

This is actually a thermal pad.

Look how thick that ISS that goes on there like that.

Or it can technically go like that.

And then our heater plate goes on top of it like so.

So this is a heating element that will heat up the thermal pad, which will heat up the backside of the socket, which will keep all these components warm and keep water from forming back here.

That's what killed my last motherboard was.

Water are the things you're gonna need, obviously as insulation like I mentioned, we use a lot of blue shop towels.

We use Vasselin.

As I said, this is actually for Steve because they keep eating a score, so he needs the best lean.

But I digress.

That's besides the point.

This is actually for insulating the motherboard, so it's a messy job.

When you do X o.

C, you need a way to monitor temperatures because, unfortunately, the onboard motherboard monitoring is not designed for sub zero it's not.

In fact, if you go below negative four on this motherboard, the course will show negative for the motherboard will show f f instead of a temperature readout as soon as you cross zero Celsius.

So that makes this completely necessary.

Because on the bottom of the pot right here, you can see we've got these different holes that were drilled in here, these air, different places, that we can actually monitor temperatures.

So you've got one right here at the very base of the pot, and you could monitor temperatures all around it.

So I'm I'm sure he's got this in there so that he could have probes all over it, making sure you have nice, even temperature.

But you just put a dab of thermal compound in their stick.

The probe in there bended up, tape it down, and then you get your reading at the actual base of the pot, which is what we're gonna be doing here today.

Let's see what else that appears to be.

Pretty much it.

So today, if all goes well, we will take my delighted 79 80 xy.

We're going to reapply my k p X thermal compounds, something that Vince designed specifically for sub zero cooling.

We're going to apply under the eye chest.

This is This is a delighted 79 80 XY.

It is not re glued that way I can reapply it as needed.

We also are going to be reapplying, obviously our thermal paste to our pot.

And that's that.

Motherboard also comes with this standoff, which is kind of nice, so you can keep it off the ground.

Well, just like that, it's like a little test.

Bet you could get airflow underneath it.

We will be also doing grab this card on our extreme water cooling, which is just a giant ice tank that's being pumped to the radiator, keeping our temperatures as cold as possible.

Our graphics cards will actually run under load about 12 c 13 see not bad at all.

But if we don't do that, we can't get the temperatures anywhere near we will want them.

So let's go ahead and set this all up, see how how low we can get it and whether or not we can actually get my CPU back up to 5.6, which is where my current CPU score is on three.

Mark and I want to see how far we can get up on single card today.

Okay, so this is our set up here.

We've only got one GPU because I really kind of only focus on single GPU today.

So here it is.

We are going to go ahead and we heat it up the pot and the reason why we did that because I observe Vince was pretty warm.

I observed, observed, Vince do that when he, uh, was here, he did with a torch.

Because when you apply the thermal pace, you because you are gonna go sub zero, you don't want to sort of harden and non spread for Matt.

And, you know, as you heat a colonel paste, it tends to thin out and get a little bit wider.

And it's sort of dissipates and spreads out Maur between the materials that it's touching.

So if we went straight to sub zero, that would never spread.

So we heated that up to about 60 see 58.1 right here.

You can see it.

So that story represents very similar to what processor at stock speed would probably be doing.

So we should get some pretty good spread of that thermal paste.

It's now we're going to kind of let this cool down just a little bit here, and then we're gonna go ahead and put in our asset.

Tono used acetone 100% acid tone because it doesn't freeze at the temperatures that dry ice will get to.

If we were using Ln to well, the Ellen to itself would be our conduit in terms of dropping temperatures.

But we use acid tone because we need something for the dry ice to melt into to make cold, which the acetone has a much lower freezing point than even our dry ice, which is like negative or minus 78 C or something like that minus 80 see kind of conflicting information on the Internet.

Bottom line is, it's pretty damn far below zero, but not as cold as Ellen to which could get minus 1 50 beyond.

Then there's liquid helium, which could go all the way to like minus 2 50 something ridiculous.

But anyway, we're going let this kind of cool down here for a little bit and then we are going Thio.

See, we can get on single GPU.

I'm aiming for 5.5 at least hoping for 5.6.

Here's our ice bucket right here for a GPU.

We will be doing GPU Ellen to slash dry ice, but I'm getting a custom card for that.

So let's go ahead.

And I just wondered if that would actually lower the temps of all.

It's a 56.9.

So what you're looking for here on the initial tests as your as your cooling it down is you are looking for these temperatures and the pot temperatures to be similar to remember where the software is measuring inside the actual die, whereas the pot is measuring the actual metal touching the dye.

So if those two are very similar, then we're in a good spot because if they were very different, which I have seen before because I used bad thermal compound that wasn't meant for sub zero, then that would tell us that we were not getting a good thermal transfer between the pots and the chip, which means instability and potential damage.

All right?

No, no, that was coming out of here.

It's the display.

Stopped working, and then it starts smoking.

Look, Look, the wires.

See?

It started from inside there.

So now we have no idea.

What are Luke Temp is one.

Okay, we're gonna keep trying to get this lower, so it's gonna take a lot of energy, a lot of ice to get the acid tone temperature down where we want this to be, which is going to be close to negative 50 ish or minus 50 minus 60 causing a bit like when you first put ice in a bucket, the ice will start to melt like that is right there.

The ice will start melting as it is equalizing.

And then once it equalizes, it'll state that temp and take a lot less energy.

Or, in this case, dry ice to keep it there.

So we're using a bunch right now to bring the temp down, and then it will be a lot easier to maintain it.

Do do do do as called upon my hand on ice.

Okay, so in all fairness, this pot is not exactly meant for dry ice.

So that two piece nature of it is probably allowing some of it to get through the sides.

I meant to tape it.

I should have taped it, and I didn't.

And so what we're dealing with now is just acid tone, just everywhere.

Fortunately, acetone itself is not really conductive.

It's now like dripping under the board.

So now XO, see, over clocking is really not that much different than regular over clocking.

Now we're basically gonna just bump it up incrementally.

It's time to go straight.

The 5.2 with all the same settings we just did.

But my main job during this is actually to regulate temperature here.

And make sure that all the temperature stays well within, you know, safe zones where we want it.

All right.

11,007.

87 on the CPU getting there, That was that.

5.4 5.5.

So we're gonna go and try 5.6 a number that I had a hard time getting stable before that.

I really think I attribute Thio.

The fact that I couldn't get the temperature is quite is cold, and the pot was probably just getting a little bit overworked.

5.6 crashed, disappears 5.6 is like it's a bit of a wall for me, having a heck of a time hitting it.

I don't think we're gonna hit.

And I don't think we're getting 5.6 on this thing.

It needs to be colder to get 5657 Vince was telling the kingpin he was telling me that, you know, this might be a 5859 chip, but it's gonna be, like minus 1 50 To get there.

You'd be surprised what temperatures can actually do in terms of stability.

What?

Okay, first we're playing 18 603 So it's going to compare results online.

Yeah, I would love it.

18 603 I'm seeing one's I've smokes, smoked and inhaled so much acetone and dry ice Number seven has moved up another one.

But in a nutshell, this is what X.

O.

C.

Is like you spend a lot of time tweaking and tuning and figuring out what works and what doesn't and very little time actually running the test, at least for me learning like this.

We also got bored and started putting dry ice in here.

So such is the life of X.

O.

C.

I guess now what we have to do is we actually have to warm this up to about minus 20 C before we can shut it off.

So about minus 25 minus 20 then we shut it down and take it apart before the condensation conform and destroy our motherboard.

So, yeah, with that guys, we're gonna go ahead and shut her down.

Thanks for watching.

I just You guys seem so interested in the live stream that I did.

I thought I have to do a video about this.

And since Vince had sent me all new stuff, I figured I might as well at least tried out.

And as you guys saw a game back, like, two spots, two or three spots on single card alone.

And I think I'm gonna try right now to go ahead and just do, like, fire, strike extreme fire, strike ultra and maybe even times by, and I know we'll see.

But I'm pretty much out of acetone and stuff, so I think we're done.

And rather than prolonging how long it'll take me to shut down the system, it's gonna go ahead and just run like, uh, I'm 95 or something.

Let it warm up to warm up to minus 20 Celsius.
