- Oh, God, it's so big.
Oh, that's a radiator?
That's not a radiator
that's a radiator.
We thought, look at this thing.
If it can cool a car
then surely it can cool a gaming PC, right?
We only have to solve the minor challenge
of figuring out how to put this,
in this.
Can't be that hard,
can it?
It just like
it's not that hard to tell you about our sponsor.

The thing about water cooling is that it's not magic.
You can water cool something,
that is to say, have liquid flowing
through tubes and blocks and radiators and pumps
and still have it formal throttle.
If you set it up with a water cooling system
that isn't adequate for the amount of heat output.
Unlike an air cooling solution,
you might not see the problem right away
but you can see in our system right here
where we've got a dual 120 millimeter radiator,
hooked up to,
our corei7990K and an RTX 30/90
that our thermals are starting to get away from us.
I mean, if we wanted our CPU to run at 80 plus degrees,
why wouldn't we just put a decent heat sink on it?
That's because while water is excellent
at moving heat around,
you still need something in a water cooling loop,
to take that heat,
and dissipate it to the surrounding environment.
So that's where the radiator comes in.
Now the conventional wisdom is that there's sort of
like a limit to how much radiator you need
before you start to reach the point of diminishing returns.
But I don't believe in fairytales like that
but I do actually.
But suffice to say
we're doing this anyway.
Alex, come on in.
Cause we gotta figure out a way to make this thing fly.
Alex, why don't we start with what this thing is.
- [Alex] So this is the cheapest car radiator
from Napa auto parts.
It's out of a PT cruiser, 170 bucks.
That's why I bought it
- But I'm a little confused because it's actually
got what seems to be dual loops built right into it.
So you've got an inlet and outlet here,
and then I did a quick blow test on it,
before we started,
and determined that it has a second loop.
It's got a second loop here and here.
Why would that be?
- So this is for your engine?
It goes from up to down,
and then we also have the transmission,
which goes across here.
But like, I don't quite understand
how this one cools things.
- Why don't we focus this puppy vent.
- We can also just go from here to here
and just do the whole thing and say, screw it.
- Oh, I see what you mean.
- Yeah.
- So we go in here,
out here,
into here and out of here.
- Yeah. And maybe put like a pump in the middle
just for fun.
- We won't need it.
That's a D five baby,
its a D five.
Before we do any of that however,
we of course need to flush our new radiator,
to avoid voiding the warranty.
Oh, Hey at least this confirms the flow path for us.
Oh yeah.
Doing a little pee there.
You know what, Alex, this might tell us what parts
of the radiator are like being cooled by this water.
- You're also pouring water off over the whole now.
- Yeah it's all pretty cold.
Oh, it's heavier now.
We needed a bigger sink in here.
Okay. There we go.
Perfect. Okay I'm back.
It works.
How do we want to Mount it?
- Had a couple ideas.
The one that I liked the most,
because it's kind of just the most dumbest,
is to just put it right on top like that.
- Aha. I mean, we've got these handy mounting pegs
one of which kind of, sort of fits there.
- Yeah. And then I was thinking just like
middle down here,
straight across,
and then just steel strapping onto the top of the case.
- So it's kind of like a performance Finn.
- Yeah. Like we could use this.
That would make my life a bit easier,
for attaching it to here.
Yeah. We can have it come off at an angle
and then have a flat plate on the bottom, I guess.
Okay. I should just hadn't even better idea.
So we can still use that L bracket stuff.
But then we can attach it to this good old 80/20,
create a little frame that goes on top.
And then we're able to steel strap that down.
It's going to be, it's going to say beautiful
but it's going to be something.
I just brought out this band called T slot hardware.
It looks like that.
It might've solved all of our problems.
We have a whole bunch
of these brackets that must've been leftovers
from one of Colin's projects.
And I think we're just going to use those and call it a day.
No this might actually turn out a lot better
than I expected.
Still not great, but better than I expected.
- My side is done.
It's at least hand tight.
Are we go in any tighter than hand tight?
- No hand tight's fine for now.
- All right, cool.
- So now bolts and these things.
Very, very loose.
This should just go on right down here,
yeah.
Oh, you're a piece of crap.
- I mean, if it's a piece of crap,
shouldn't we look to the craftsman.
- I'm not saying it's good,
- Or should I say craftsman.
- I'm gonna blame 80/20 for all of my problems from now on.
- Which 80/20,
like 80/20 aluminum?
Or the 80/20 rule.
20% of the effort that gets you 80% of the result.
- Okay. Yeah, we are definitely going low effort on this.
We're all about reduce, reuse, recycle here today.
This is our most testing robot.
So well not a robot or most tester.
Hammer goes,
turns on the lights that you know exactly when
the most started moving,
but it's outlived its usefulness.
and I'm just going to use parts of it for this.
So this is the basic thought,
skills across here.
I have no clue if this should be wider or not
but I think it'll be fine.
Okay. This should be,
oh my God
Oh, it's even peeing on me.
This is so stupid.
- Not bad at all.
Now all we need to do is,
get some fans on it.
- Implement.
- Oh fortunately,
we have an easy plan for at least one of those things.
We're going to take these zip ties,
and run them through our fans
light cell.
See that?
- Two zip ties per fan?
- Oh yeah. more than that was never an option.
- Yeah. We have kind of outdone ourselves here.
- I mean, if it's stupid then it works,
it's not stupid.
- So there's a couple ideas,
of how to do the tubing,
for the transmission one it's easy.
We have just adaptors.
- Perfect - work.
- Love it.
- For the bigger ones,
I have a really terrible idea.
- I love it.
- So we have a bike and our tube here,
I don't know why,
but we do.
The basic thought,
was to cut this,
stretch it,
around those right there,
use that as a reducer
and then just cover it in tuck tape,
probably duct tape,
then maybe a towel,
to soak up the stuff that gets through that,
and then wrap it in tuck tape again.
- Okay. I don't have a better idea right now.
- I hope this works.
Cause that was a bike tire that has destroyed.
That must be kind of sad.
- Did you kill it already?
- Oh yeah. It's dead.
Super dead.
- I was hoping to give it a little bit
of thought before you destroyed it.
- Not so bad.
- I've seen dumber stuff under this roof.
Maybe more zip ties
- And then let's go,
nice long piece of tube to go on there.
- You can always tell when it's a Friday,
and I'm supposed to be hosting when show
because things get a little,
- A little this.
- This.
- This is a bad one.
- Yes. And also, no, this isn't even that stupid.
Now that I see it.
- Yeah. A couple of big boys,
and then a couple of small ones to the pinch.
- Yeah I got it.
I'm coming.
I see the vision here, Alex.
This might actually freaking work.
I'm sorry Alex,
I didn't have the right amount of faith in you,
and I should have.
- Oh this is what's going to be doing the transmission
cooler loop.
So it was Clint might be too big
but I guess we'll find out in a second.
Once I tighten it down a bit
or like actually not very far off.
- Wonderful. And just one more.
- I can hear the why's coming from around the world.
Is there any leak tests?
Like we're basically assuming it's gonna leak aren't we?
this is pretty drippy
for a case that has an open hole on the top of it.
You can't get me a piece
of plexi or something or a plywood even.
- I guess that would be more smart.
- Don't mind me.
I'll just hold this here.
- I'll rag.
- Alex come on.
- I have a better idea.
- Arms are getting tired.
- I have a different idea.
So what we do, you place it on top,
and then we just put a parts trainer neath it.
- No, because it's going to drip
from lots of different places Alex.
For better, for worse,
this is a thing that exists now.
So am I just, am I just disconnecting this thing?
Like why not right?
- I guess so yeah.
- Okay I mean it's near the top of the loop.
How much water could leak, right?
- Quite a bit I would say.
- And there's only one way to know for sure.
No, no, actually I think none is going to leak.
here we go you ready?
- Sure. - Boom none.
See that?
- Damn.
- Yeah. - Not bad
- Just going to ratchet strap this down here.
You know, gotta be nice and secure.
Oh look just like I planned,
We're adding the feature of having a shutoff valve,
so that you have a shutoff over here.
- Yeah. Just like your plans.
- Yes.
- Thank goodness we have the 40 ouncers.
I'm so ready.
You only live once Alex come on,
hook me up.
- Okay.
- Here we go you ready?
The fans aren't turning on
are they supposed to?
- They're not plugged in yet.
- Hello?
- Hello Mister pump.
- [Andy] Its leaking on top.
- Oh yeah. It's leaking pretty good.
Okay. We need more absorbent materials.
Do we have anything reusable?
Well no I need it on this side.
Oh yeah.
Okay. There we go.
Now we're talking.
- It's so bad.
- Well, yeah
We never ever thought at any
point that this was not going to be bad.
Hey, you turned off the power supply.
- Yeah, because it was leaking on the top of the computer.
- I mean, that's why we've got wood on there,
instead of scraps of rag,
like you were going to put there.
- We've also got scraps of rag.
- We do have both that's redundancy right there.
It's protection.
- I can't tell if it's leaking lesser.
If it's all just going into that rag.
- Oh, it's all going into the rag.
It's leaking lot.
Wait, am I just filling to like compensate
for leaks right now?
No, I have it actually like this pump to go at full speed.
I'm going to disconnect the PWM controller (mumbles)
- Oh my God it's so much.
Okay. I have a different idea.
- He goes, Whoa.
Hey ho.
How you doing there buddy?
Oh God.
It's so big.
Oh, (beep) we have a problem.
Did you take off your tape?
- Yes should I kill it?
- No, no, no, no, no.
That will be worse.
We just need more absorbency.
- Okay well just a second.
I'm coming with a fix.
- [Andy] Oh it's on the graphics card.
- Oh it's Hey, stop.
Stop. Stop.
You need to stop?
Can I get another small zip tie?
Alex can you hold this?
Someone?
Do you have the zip tie by any chance?
- A water boss.
- Now I feel like I'm working on like a field wound.
- Okay. Do you want to move?
- It's a little dumps - Running dry.
- Well, I'm working on aren't I?
I can't wait for this stupid slow funnel.
- My God, this is so bad.
- What do you have?
It's aquarium puddy.
- Wait, you had aquarium puddy this whole time?
Why am I just finding out about this now?
I don't actually know
that there's any water in the CPU block Alex.
- Doesn't really look like it.
We need more stuff.
That's not helping at all.
Why did we put it on top?
- That was your idea.
- It was Andy's idea.
- It was not Andy's idea.
- [Andy] Now you blame me? - Don't you blame this
on gentle Andy
In response to our earth earlier query
as to whether it's just losing water at this rate.
I think it might be.
We can't get the water up there.
You might've been right about the head pressure.
I was so sure that the D5 would come through.
Its a D5.
One thing we can do is we can tip it.
Once it's full,
the head pressure issue becomes a non issue.
We can also try power cycling it again.
Don't hit the computer though.
I'm just going to do the pump real fast.
Real fast.
Real quick.
- Go back on pump.
- No, see it's got bubbles in it.
- Yeah.
- That's why it's not able to do it.
Oh, it's full.
- Oh wait. Yeah.
- Those trips are big and coming from very high.
They're hitting this tube,
which could put the graphics card in jeopardy,
but that's good.
I mean the graphics card being in jeopardy is not good,
but the,
- The CPU getting water's good.
- Yeah. Is the CPU getting water?
- It looks like it yeah.
I had a joke in my head before this
that I was going to call it a success,
if we didn't kill any hardware,
and it's become a much more real thing than I expected.
- Holy crap laws we have flow.
Where's my sweater.
lttstore.com.
Okay? Made of the finest french Terry
stealth hoodie.
LTT store.
I'm starting the stress test.
So CPU burner,
we were doing 16 threads, right?
Alex? - Yes.
Oh my God.
- And wait.
- There's so much water.
- Alex. Help me out here.
The resolution is 2560 by 1920, right?
- Yes.
- Okay. Where's the CPU burner?
Hold on what were you using to monitor HW info?
- Yeah. What's our (mumbles) looking like?
- I'm checking.
I'm checking.
I'm on it.
Hold on we're running out of water here, boys.
Good. God, we losing a lot of water.
Are the fans even running Alex?
- No.
- Well, why not?
What have you been doing
this whole time? - Can you go grab some
elastic standers?
I've been making sure that we don't kill the system.
- Yeah. Well that's gone great isn't it?
- It is. Its not dead yet.
- Does this have molex on it?
'cause we could use this one.
- Oh yeah, that works.
Oh wow.
This is stripping more than I thought.
- Andy, do you have footage of this?
- Yeah, this is all for nothing.
If we don't capture it on video.
Oh crap the pump's about to run dry.
- Do we have fan spins?
- [Andy] No.
- What? No fans are spinning?
Oh crap.
There's a lot of what's going on here?
- I think the pump is not pumping.
Shoot it's it's overflowing.
Come on pump.
Come on baby.
Oh, she's leaking water.
We're getting almost no flow to the CPU.
- Jumper fans on?
Fans not on.
- The power supply is not connected
to the test bench
- Oh I'll do it.
- We have flow to the CPU.
CPU tamps are holding,
our maximum is 77 degrees.
- Okay. That's good than before.
- That was when it wasn't flowing.
We are at 67 max right now.
- A couple of fans.
- We got four,
we got four fans spinning.
I just got to add some more water.
- Why are the other ones not spinning?
- Ah, they could not be hooked up.
I don't know.
I just started checking stuff.
- Oh my God this Molex connector
is just absolutely gone though.
- At what point do we just rip the pins out,
and check it in?
- Okay. I'm going to find which rags are not wet
and move them into spots where rags are wet.
- I've got more fans spinning now.
- Good news our CPU is only 63 degrees.
GPU is at 42,
so that's also way lower than before.
- Okay. All right.
We've got six fans spinning.
Where's the rest of my fan connectors here?
Alex. Did you bring enough fan connectors?
Oh, come on.
Oh my God do you have side cutters?
This is a three pin.
The fans for pin Alex.
Yeah, that's better.
- Oh geez. We have another leak.
Okay. So that needs to go. - I can't see anything.
This also needs to go.
- Yeah. Am I spinning another one?
It's got the paper towel in it Alex.
Wait, hold on.
That's an industrial.
Alex. We're going top up the water.
- Just a second.
it's going to get all over the table
if we don't top up the water.
- So the good news is 4.9 gigahertz,
on what is that?
Eight Cores are currently at 65 degrees on the CPU.
45 degrees on the GPU.
Way better than before.
This is clearly a win.
- You know, Alex.
I think that it's going to be very hard
for us to evaluate the efficacy of the radiator
when what's actually happening is we are just
completely replacing the water with cool tap water.
Every, you know, probably 10 to 15 minutes.
- This is PC gaming
at its best. - I have another spin,
I got another spin.
- The good news is the transmission ones aren't leaking.
- That is good news actually.
- Oh geez the paper towels become saturated.
- Hold on I need one more extension.
Hey, why are you not spinning?
Is it spinning now?
- [Andy] No.
- How about now?
- I don't know how much longer we can keep this running.
So we're going to have to conclude it now.
We are at maximum turbo on our CPU,
4.9 gigahertz on all cores effectively,
cause those threads that we're not using
for the CPU burn test are being used by
from arc for the GPU.
We are maxed out,
so our hottest core,
is at just 63 degrees that compares,
to over 80 degrees,
with our wimpy dual radiator.
Okay. So that's a big 20 degree improvement,
as for our GPU,
let's fire up full Mark here,
we are sitting right pretty at about 35 degrees.
What were we at 40 before?
- [Alex] 60.
- 60.
Wow. We've dropped 25 degrees on our GPU
and all it cost us was Holy crap.
I don't have any water Alex.
We're going to have to top this up in just a second here.
And in terms of like acoustics,
and convenience factor,
it's pretty low.
