So the basic premise of today's cooling experiments
with Alex, I super don't know why this is here,
is that the MacBook Pro 2018 does a pretty subpar job
of keeping its Core i9 CPU cool,
if you opted for the tricked-out Core i9 model.
Well, we think we can fix that
using the same cooling principles
as we were able to fix the Razer Phone
and its throttling while gaming with.
That is to say, liquid metal cooling.
But then there's also like a radiator and a reservoir
and some laptop stands and some water blocks,
so I have no idea what the is going on today.
Why don't we all find out together?
CableMod's configurator now includes
a customizable RGB backplate
that can enhance the look of your GPUs and SSDs.
It's compatible with RSync, RGB Fusion, Mystic Light Sync,
or CableMod's own kit.
Find out more at the link below.
You pulled out all the stops,
like there's two iFixit kits.
Yeah.
What are we doing?
Oh, I actually just had a difficult time getting it open,
so I thought that I might've stripped one of the screws,
but it's actually just the P's and not the T's,
so I was just an idiot.
So step one of any cooling project is,
wasn't me, rip open the device you're trying to cool.
So I will take you up on one of these kits.
These things are kind of nerve-wracking to open.
Cause they're, how much is this one?
Five grand?
Six grand?
Yeah, five grand-ish.
You could like that.
It looks so much easier in iFixit's video.
How do they do that?
Are you free?
Yes.
There we go.
Beautiful.
You can really tell what gives it the rigidity though.
Yeah, that's pretty nice.
Yes.
Can I make a computer case
out of a solid block of aluminum?
Gorgeous.
How many bits would you go through?
So do you want to know my really bad idea
that probably won't work?
Sure.
You want to water cool it.
Yeah.
I really don't know
if this is a very good idea.
I don't even see how the heat pipe comes off
to be perfectly honest with you.
Usually it's more apparent.
You have to take the whole board off
and the screws are on the other side.
Okay, so what are we taking off?
Track pad first, I think.
Track pad out?
How are we keeping track of all of this?
I've been placing them in here.
I will be back.
So lower are these ones.
Track pad upper are these ones.
Track pad clippy chums.
Also there's T4s and T5s in here.
Yeah, that's fine.
Let's draw the fans on there.
There, is that pretty self-explanatory?
Yep.
It's got a bigger head.
Ugh.
Where'd those two come out of?
It was right here and right here.
Okay.
What was the purpose of this screw being shorter?
There's plenty of room for it to go further if it needed to.
Oh, they're just a different screw.
Yeah, different screw.
I think you're drunk.
I don't know how you're not getting it with the T4.
It's T3.
Do all of these have to come out?
Yes.
Oh my God.
Yeah.
Right?
Oh my God.
Is this yet?
This is yet another different screw.
Holy ballsack.
So that's top left.
And there's more screws underneath that.
Oh wow.
So this little thing hooks on a little thing here,
then goes down.
Why you do this?
Perfection, Linus.
I think this whole thing is a mistake.
That's what I think.
Now I just kind of want it to go back together and work.
I think we're close.
I'm starting to think we need to do away
with the grand plans of water cooling
and whatever this is though.
But it would be so fun.
Fun?
Fun, yes.
Are you having fun?
How many types of screws does it take to get to the fun?
16.
I think we're just gonna have to peel off the adhesive.
Uh.
Something's holding.
Oh, there must be a ribbon under there.
Yeah. Are you for real?
Yeah.
Look.
There's a ribbon right here.
I just missed it because it's super small.
There we go.
Now we can probably lift it up this way.
That's it.
This is a royal pain in the ass.
I actually feel legitimately very bad
for people whose job is to fix MacBooks all day.
That's their cooling solution?
Yeah.
No wonder the thing thermal throttles.
How much does it even weigh?
I actually want to know.
Okay, nevermind why I have this thing.
For your drugs?
53.
54-ish grams.
By contrast, a desktop processor would get a cooling solution
that weighs in the neighborhood of 1.2 kilos.
That's a pretty excessive cooler, bud.
Yeah, okay, that's true.
I don't even think liquid metal is gonna solve this.
No, it'll help.
Like, that looks like some not great thermal paste.
Well, we have to try.
I mean, we don't have to try, but like, actually.
We're Linus Tech Picks.
We have to try?
Yeah.
So it's conformal coating time, then.
Oh, wow, that's a lot.
Can I help pick some of that up, or?
Yeah, let's just spread that around.
No components are dying here today.
You can say with a straight face that they're not dying
because they're dead already, or?
We might want to get the heat gun out
to have that dry a bit faster, though.
Well, look at it this way.
MG Chemicals says that you're supposed to do three coats,
but we'll probably be fine with one.
Really not how painting things on works.
That moment when people are watching a video on YouTube,
and they are literally watching us watch paint dry.
So this is it. Liquid metal time.
Yeah. Do you want to do it?
Sure. I don't have a liquid metal.
Hell yeah, brother.
I'm gonna prime it.
You wanna give them-
I made that mistake last week.
Why are you doing that over the board?
You don't have a lot of time for this.
It's like a ball of it.
Oh, that's kind of sketch.
Yeah. There we go.
Okay, we're good.
Oh, there's some there.
We should get that.
I think you could use a touch of water.
I don't think so.
All right, fine.
Maybe just try spreading it around.
Fade is fade.
Actually, that's maybe even too much.
Wow.
What the actual ?
Okay, we're not gonna get-
And we're done.
I really want to hear an ASMR cover of Chopped Cimino.
This is such a surprisingly stressful operation.
Yeah.
I was expecting it to be more like-
A normal laptop?
Yeah, all of the other laptops that are taken apart,
which has been like, boom,
and like five minutes later, you're done.
I'd like to think you go a little more carefully
than, boom, but pretty much.
It's no wonder Rossman didn't think the iMac Pro
would be a big deal.
Like compared to tooling around with these all the time,
it's nothing.
So we are now liquid metaled,
and now we have to put this back together.
Yeah.
Do you remember where the screws go?
There was one that went on the bottom, right?
So we need-
No, that was on the top.
It was just really hidden.
It's possible that there's like,
this is similar to,
no, I'm like quite sure.
Okay, so there's nothing that goes in on the bottom.
Not without permission anyway.
Right, we can put all the connectors back on.
Yeah, don't go gently.
Is that like a Dylan Thomas reference?
Who's Dylan Thomas?
Poet.
You don't get to quote a poem if you don't know who it's by.
That's like actually a rule.
It's a screw that goes into a screw.
It's screw-ception.
No wonder we couldn't figure that one out.
Holy crap.
Can you imagine if we had tried to do this
without the project mat?
We would have been so screwed.
Wow, that's really obnoxious.
Like you have to have this whole thing on.
What is this?
That goes on this little peg here.
So you sort of get it in position,
and then give her a push.
Fun.
So unnecessary.
Everything about this is unnecessary.
It could just sit on there,
and you could just screw it in.
Oh, we probably shouldn't do that quite yet.
I wanna see it.
Fan spin!
You don't think that we like need these, do you?
I doubt it, but let's put them in anyway.
Like it's not hard.
And it wasn't.
It is!
Ah!
Ha ha!
Oh goodness.
Wow, that was stressful.
That moment when the delay
was just a moment too long for comfort.
So, you need screws in the MacBook for it to turn on.
We know that now.
What the hell, Apple?
Why?
That needs to be a gift, that moment when you can just-
How does it just turn off?
Yeah.
Okay.
Maybe it was just unhappy
because it tried to resume from sleep,
and actually it was like unplugged for a while.
Hold on, let me try and log in here.
Okay, track pad's working.
Shall we get some after results?
Yes.
I know if our operation was worth the stress and time.
So not cool.
Get it?
Because it's about the MacBook Pro.
All right.
So we're looking for 1083.
1083 is what we had before.
Okay.
Didn't we get like 1600 in the ASUS?
Yeah, but that was with low-emotrons, fair.
Yeah, it doesn't totally count.
The fans haven't even ramped up yet.
Are they working?
Great question.
1068.
Okay, that's within margin of error.
Should we just hit it again and-
Sure.
No, it's ramping, I think.
Yeah, yeah, it's ramping really slowly.
Interesting.
Does it normally take that long to ramp up?
Yeah, I think they're pretty on the go
by the end of the Cinebench run.
I wonder if the liquid metal is helping us with that.
1086, so-
So exactly the same.
So, okay.
Performance.
The same.
But now let's try the longer test.
Normally use the F keys, but-
What, you don't like the touch bar?
I really hate it.
Bitch, cry some more.
The Blender BMW test stock took six minutes and 11 seconds,
and with the liquid metal,
it was six minutes and seven seconds.
So basically the same.
So a big fat waste of time.
And the Classroom took 22 minutes and 58 seconds stock,
and took 19 minutes and 26 seconds with liquid metal.
No!
So that's actually pretty good.
That's like 13% faster or something like that.
That's actually like a pretty big improvement.
So there was a point to doing this.
Yeah.
And then how loud was it
towards the end of that second test there?
Like spooky quiet almost.
Well, that's fantastic.
So once again,
liquid metal saves the day.
And once again,
we are not recommending that you try this at home.
this actually comes in the box of the liquid metal we don't recommend doing this because
the risk of damaging your hardware during the disassembly the application of the liquid metal
and the reassembly is quite high not to mention that we have definitely voided the warranty on
this machine in the process and the uh the benefit is maybe 10 to 15 faster renders which is actually
pretty sick but over time liquid metal does actually need to be periodically reapplied
and that's not a great user experience no no it's not i'm just really sad that we can't put blowing
the trons on the bottom yeah me too we'd have to like actually cut holes in it because of the whole
case extrusion stuff intrusion stuff mass drop is back with another deal this time on the sennheiser
open backed hd58x jubilee headphones these were tuned by
asterisk.com
axle grell of sennheiser and mass drop based on feedback from the community they feature new 150
ohm drivers and a colorway inspired by the hd580s they're clear fast with a dynamic sound profile
and they've got a glossy black headband elliptical ear cups and replaceable soft velour ear pads
they've got a detachable six foot cable and you can get yours today at the link in the video
description so thanks for watching guys if you disliked this video then you probably work at
apple.com
but if you liked it and you like our fix for the macbook pro and it's thermal issues you can
hit that like button get subscribed and maybe consider checking out where to buy the stuff
we featured at the link below so we'll maybe what we'll have a macbook down there we'll have
some thermal grizzly down there octoon and all of that oh it's also surface laptop in there too
throw that down there yeah why not uh while you're down there we'll also have a link to our
merch store which has cool shirts like this one and our community forum which you should totally
