Oiii!!!! OK! Linus has absolutely no idea what it is.
I am so stoked.
In this video we're going to cool a PC with fire
and then take it to Linus Tech Tips to overclock it to its limit.
So if I understand correctly, we can go to subzero with this cooler
and all it costs us
is some Hacksmith engineering and a little bit of propane fumes?
I'm in!
There's a physics phenomena that you use every single day,
and I bet you didn't even realize.
It's called evaporative cooling or enthalpy of vaporization.
Basically, heat is pulled away from a surface
when a fluid changes state from a liquid to gas.
These kinds of systems are all around us.
In fact, your body uses the same concept in an open loop system.
When you take a drink from Hacksmith.store water bottle.
When you get hot, your body releases sweat,
and as it evaporates, it cools you down.
Bogdan, what are you doing?
Evaporative cooling.
Check out the back of this refrigerator.
This is a closed loop cooling system.
The liquid refrigerant starts compressed, and as it is sent through the lines,
the pressure reduces and it becomes a cold gas.
This is what cools your fridge.
The gas then makes its way back to the compressor
where it gets compressed back into a liquid and the heat gets dissipated
across the radiator on the back, thus completing the cycle.
So what kind of fun can we have with this?
Well, I was thinking about PC cooling.
Typically it uses a fan, which means your CPU can only get down to room temperature.
And no matter how powerful a fan you have,
you're not going to get your computer below room temperature.
Linus.
Whoa, hey, whoa ho.
So I have this counter-intuitive idea.
What if we could cool a PC below freezing using fire?
Here's the plan.
I'm going to take a propane tank and turn it upside down
to release liquid propane into our PC.
When the liquid hits our warm CPU the liquid expands into gas
and cools the CPU in the process.
Instead of compressing it back into a liquid for a closed system,
we're going to dump it overboard and light it on fire.
Let's get into it.
The first thing we need for our PC is our vaporizer, or phase change cooling block.
I've gone ahead and done a bunch of math to figure out the perfect nozzle
to ensure we have lots of cooling and a long runtime.
There's also a T splitter which has a nice flat base which we can
polish and make perfectly flat to attach to our CPU.
And we've got this nozzle right here.
So what I'm going to do is we're actually solder these two together
so the cone sprays directly onto the bottom of our T fitting.
And what that'll do is make the bottom of this really cold.
Which is exactly what we want.
We've got our beautiful Ryzen... and that needs to go right there.
Look at that.
Actually, that's a beautiful cut.
It's a little hot.
Got our propane line, we've got our bracket.
That's probably sufficient.
This goes upside down.
So we're feeding liquid directly onto our CPU.
Right now it's at room temperature.
So we should have quite a bit of degrees to cool off before it goes below zero.
Ben's going to light that
so that we're not dumping propane at the atmosphere.
We've got nothing flammable above or nothing flammable around.
Ooh, it's cold. It's cold. It's cold!
It's really cold.
Currently it's 14 degrees.
We're at 12 degrees. That's a good ten degrees below room temperature.
So as we found out yesterday, this old Ryzen five, 1400
cannot handle subzero overclocking.
Overclocking is telling the processor
to run faster than it's normally meant to, and that creates a lot more heat.
So the colder we can get it, the more we can overclock.
I've gone out and I've picked up a brand new motherboard, says the Asrock X670E PG Lightning,
and a brand new Ryzen 9 7900 X
Gotta do the ol' Linus
and just drop the whole thing.
Check this out.
I am puddied up the entire CPU socket.
Should be nice and watertight and hopefully get some subzero cooling going on,
or blow up our brand new, really expensive CPU and motherboard.
I don't really know what I'm doing, so that's not out of the question.
This is so ridiculous.
I cannot wait to see Linus' reaction
when he realizes what this is.
It's not going to...
It's not going to do anything scary right?
Whoo! Nerves are high.
Whadya say? Should we subzero this thing?
I think so!
That's full cooling open.
We're dropping temperature 19, 16, 13, 10
7, 5, 2, 0!
-2 we're subzero!
-11, -12
We are literally flame throw cooling of P.C..
We are running 5.6 gigahertz reading six degrees at 115 watts
on our Ryzen 9 7900X.
You can see the coolest part of the computer is the block.
Your lines are on fire Bogdan.
What is going on?
It's frozen and on fire at the same time.
*everyone laughing*
How cold do you think we can get it?
You want to see how cold we can get this thing?
-19, -20,
-21, -23, -24 it's still dropping.
-25, I wanna just keep spewing liquid.
Those lines are fine. They're buona end they can handle a little bit of warmth
Everything is fine.
Everything is under control.
If that droplet of propane hits your skin.
You're going to first get frostbite and then you get third degree burns
Almost immediately.
And this is this is where it gets dangerous, actually.
And by dangerous,
I mean everything that is frosted over in here is now slowly starting to melt.
And I'm really hoping my Silly Putty and all my
shoved in shop towel is going to be
sufficient enough to keep this thing from getting water in it.
There's a few things we need.
Obviously me manually controlling the valve by hand is kind of not ideal,
and then we need to make some kind of radiator.
So when the liquid does come out of the other
end, it's not spewing all over the hoses.
I think the biggest difference is going to be making this thing
a little more reliable and easier to use and making a little bit safer,
whatever that means.
To make the release of propane computer controlled, I'm going to be
designing a PCB in Altium Designer with the Altium OctoPart integration.
It's super easy to find and add components to your projects.
The circuit takes the signal from the CPU fan head
and switches this solenoid valve on and off to control
how much propane gets vaporized.
If you want to see the full schematic diagram, check out the project on Maker.io.
All right.
Electronics are good to go.
Hey, Charles, think fast.
There's never been a dull moment at Hacksmith Industries
since we got sponsored by Gel Blaster.
Gel Blaster is the gift of the holiday season.
This revolutionary toy.
Blasts water based gelatin that are all natural and nontoxic.
That means no stain, no mess, and no cleanup.
Use my code HACK10 to get 10% off the order
of the Gel Blaster Surge XL. Link in the description.
I think I can honestly say that this is the most fun or most fun I've had.
Filming a sponsorship.
They don't really hurt because they have a bit of a sting to them.
So they.
It's still fun.
Oh, shoot.
Honestly, I'm going to take one of these home with me.
All right, Charles, get back to work.
So, as I was saying, the electronics are done,
Let's see how Bogdan's doing on the flame expander.
In order to make sure that we can actually make this out of sheet metal.
I need to double check to make sure our holes
are far enough from the edge so that they don't deform.
So we're not going to be using 16 the sheet metal.
And that's 0.0625.
That's going to be 6.35. We are 8.2 millimeters away from the edge.
So I think this design will work quite well.
We have our two logos in the position of the fans
and they'll make sure that we can distribute
that propane nice
and evenly, have a nice large flame and no liquid propane in our computer.
And that is ready for laser cutting.
Well we've figured out is our cooling system works really well.
But we have no clue how to overclock a computer properly,
Oh it just crashed.
Especially not to the power limits of this thing is capable of.
So I think we need to call in an expert.
And I think I know just the guy.
That is cold!
I mean, if it's stupid and it works, it's not stupid.
CPU temps are holding.
Un-freaking-believable.
Linus has absolutely no idea what it is.
I am so stoked.
Do you want to see this? I think so.
As long as it's not too dangerous.
I mean, those guys.
Oh, I was joking.
But you guys don't sound like you're joking that much.
Okay.
Okay I'm doing it.
Yes. Fire.
Yes. That's exactly what we're doing.
Is this an actual product?
Oh. Okay.
Don't drop.
Don't get hit by the flames and don't die.
The warnings seem appropriate, but if it's on fire, everything's okay.
And if you're confused, call Hacksmith.store.
But what I don't know is what exactly it is that I'm looking at
and how this could possibly have anything to do with cooling anything with fire.
There's nothing in this.
This is just a flame expander to make sure that we don't get liquid propane
on the computer. Ah flame expander.
Oh no.
So, if I understand correctly, we can go to subzero with this cooler,
and all it costs us
is some Hacksmith engineering and a little bit of propane fumes?
I'm in!
You want to light it up?
I mean, we've come this far.
Let's goooooooo!
Oii! Hey. Oh!
Just a bit further away.
Oh, that's so nice. Yeah, that is very nice.
What kind of specs we got on this computer here Boggy?
I believe this is running a Intel i9 13900K
with over 800 watts of propane cooling.
So it should be able to get this thing nice and cold and nice and fast.
We're at -10 Celsius so far. -11.
And this is with restraint.
This is with the regulator going, yeah, this is about 10% flow.
This is just enough to keep the flame lit.
Okay, let's start overclocking, though.
Let's give her the beans.
Should we just give her the beam?
See what happens?
All right.
We are now de-regulated
Who needs regulations??
I can hear the liquid propane shooting into the flame expanders.
Oh, my goodness.
Our poor case is coming apart at the seams.
6.1 GHz
Not too bad...and delicious!
4.5 on all the efficiency cores.
This thing is actually ripping.
We're almost at 42,000 points.
Damn, Daniel.
This thing is actually overclocking like a beast.
There's no doubt about it.
Hacksmith Industries may be the world's biggest, absolute mad labs.
By the way, I love your portable marshmallow roaster.
Wow. The front of this case
is looking pretty gnarly.
Warping a little.
Havin fun out here Boggy?
Oh, yeah, totally.
I'm just glad it's not my monitor.
Oh. Oh, no.
Well boys, did we succeed?
Oh, yeah.
CPU got up to 6.3 GHz.
42,000 Cinebench.
Beautiful.
This thing absolutely rips.
Nice work, boys.
Also tasty, too.
Well, this doesn't prove that you can cool a PC with fire.
I don't know what is.
Make sure to check out the video Linus made to see how this PC was built.
Thanks for watching.
