So, now we're at Lean Lee's Mad

Scientist Lab. Jameson, CEO, is here as

well, and he's going to help show some

of this just like last year. But the

quick run through of what they have. So,

this is the Lanquil 207 XL where this

has a basically it's like a double

barrel shotgun uh of cross flow fans.

So, this is something it's very

interesting. This sockets into the

bottom of the case,

sits here, shoots air straight into the

GPU. So, you've seen cross flow fans on

cases like the Flow where they just kind

of slap it on the side. I'm very curious

to see if this one actually has an

impact. We'll talk more about that in a

second, though. But, it's two 170 by30s

in the front, 140 rear, these two in the

bottom, $110 price point. Uh, and

they're going for like basically as

cheap as possible performance kind of

like the past like 207 217 series. For

this case, we'll be talking about

there's this separate chambered

intake for the liquid cooler. So,

they've got this completely blocked in

where there's a glass sheet on the

inside in front of it. Uh, air only

comes in through here, goes out through

there. Uh, similar to one of Corsair's

cases we looked at last year in terms of

just separating out the cooler. This is

the UX100 we talked about. This is a

floating case. So, we saw one of these

at Monttec that was implemented

differently, but um basically the front

edge here floats. The intake for the GPU

is in the bottom and then they've

shifted the motherboard tray. The

Lancool 4 also makes a reappearance. So,

this is $130. Lean was showing this, I

think it was last year with the fans and

glass that we showed. Um and now it's it

should actually be done. So, uh, the big

change from last year is this bottom

chamber where now it's kind of like a

separately compartmentalized chamber.

And so, you see all these metal pieces

on the table in front of the case. Those

can be added in. Turns it into this

basically. And, uh, and then the options

are just where you want to point the

air. So, these are kind of the main ones

that are interesting. There's also a

V2000 we're going to talk about. This to

me is primarily interesting because of

this front mesh style, which we'll talk

about. And then this thing is very

strange. Uh,

>> which we'll

>> You mean cool, right?

>> Yes. Let's do a a really quick teaser.

Can you just

>> for the curved screen that you always

wanted to find like a good angles,

right? That's why we make you rotate.

And you see how close it is to the GPU.

Um, but don't worry about it because we

can make it higher.

>> So, this is this is a it's like

hydraulics for your car except for your

liquid cooler. There's a lot to talk

about today. uh for Lean Le's stuff for

Computex. Let's start with the XL.

Before that, this video is brought to

you by ID Cooling and the Frozen A720

cooler. The A720 air cooler performed

well in our testing last year. The A720

is a relatively high-end dual 140mm air

cooler with seven heat pipes. We found

the use of larger fans can be beneficial

to acoustic performance given the

thermals, although you'll want to check

your case for compatibility given the

taller nature of the cooler and its

fans. ID Cooling uses an all black look

for its A720 and includes mounting

hardware for all modern sockets. Learn

more at the link in the description

below. All right, so 207 XL. The reason

this is interesting to me is because of

the cross flow style. This has been

tried a few times in cases we reviewed.

We worked on a miniITX case called the

meshless AIO, which they later renamed.

It kind of started the more recent trend

of popping this up. It worked okay. Like

that case was designed ground up around

a cross flow fan, so it kind of worked.

the trikes fla they shoved the cross

flow fan into an ATX case didn't really

work wasn't a good use of these the

reason cross flow fans exist so you'll

see these in like standing I don't know

air purifier type setups uh but what

they do best is it's it's also known as

a transverse fan where basically the air

will come in and deflect at almost like

a it's like a perpendicular to the axis

angle for the air and so what it does is

it creates a curtain of air that's very

laminer so if you were to imagine the

air coming out this way. Uh all along

the blade here, it's going to be

basically laminer flow, low pressure, uh

but you get like a really clean sort of

sheet of air in a very predictable

pattern as opposed to something like an

axial fan that's that's more wide. And

so they're socketing this into the

bottom. Basically, these shoot air

straight up into the GPU. This is all 3D

printed right now. All this stuff is is

mockup which uh Jameson will talk about

in a second. But um that goes on the

side and it's just meant to be kind of

like a a flow guide to direct the air

where it's supposed to go. So I was

asking we were just talking about this

where you know the question I had for

you was okay so

crossto fans half the time they're like

a gimmick. Uh the question was have you

done any AB testing of if you do like

two 120s here? Yeah.

>> Right. And the same same everything just

120 is roughly the same noise versus

cross flow. You're saying you're seeing

an improvement.

>> Yes. So uh actually um when we do the

207 XL um our our initial idea was to to

do 2140 the bottom and we

>> use that to compare to the original uh

207 which has 2120 there

>> but we don't actually see the

performance gain right. So, and once we

actually implement this cross flow

inside, we see um around three uh

degrees improvements um

>> on the GPU

>> on the GPU side.

>> And also um because when you do the um

air cooler setup,

>> um the drawback of having a bottom fan

underneath the GPU is that you will uh

also shoot out the heat upward

>> and then get recirculate by the air

cooler.

>> Yeah. Uh and then but this type of

design because it was so focused on the

GPU,

>> it doesn't spray as much.

>> It doesn't spray as much. Yeah. Yeah.

>> Right. Yeah. So 3 degrees is in our

testing that would be a lot like the the

top to bottom range for a GPU is not

that big. Right. So

>> 3° is kind of a lot. the 207. Part of

the reason it performed well in our

testing was Lean Lee sunk this down, put

the fans in the bottom, move the power

supply to the front, kind of gets it out

of the way, and then you're getting the

the fans basically as close to the

intake in the quarter panel as possible.

Um, one thing you and I were talking

about though is I guess with cross flow,

uh, since the air is going to be coming

in straight through the side like this

and then up rather than having axial

fans here, in theory they should do

better with drives that are mounted in

the bottom because they're going to be

less sensitive to the resistance.

>> Yes. So, um, because like when you do

normal fan, right, so the air direction

is, uh, straight. Mhm.

>> So it will requires um a lot of the um

having no resistance underneath the

normal flow fan whereas this because

it's uh

>> straight in from the side.

>> Yeah. Straight from the side.

>> You said you just started working on

this like two months ago.

>> Yes. uh like I told you like we it's

always uh in our pipeline that we wanted

to create the uh the best air um you

know out of box thermal performer uh

type of case but well I think we are

kind of reaching

>> the

>> the limit

>> the limits where if you just use their

standard flow

>> I mean obviously you can uh make the fan

size bigger and bigger and bigger

>> but it's started to make me feel like uh

it just without I think without doing

too many of the drastic change, it's

hard to mix the actual improvements.

>> This I'm not going to spend a lot of

time on cuz really the main thing I want

to point out, there's two aspects, but

one is uh this currently has got a

filter on it. Can be glass or filter.

That's a glass one right there. Um and

basically it's just an option of if you

want to chamber out the cooler in the

side to totally isolate it from the rest

of the system, then you put in this

filter option. uh glass goes in front of

the cooler and then the air just goes in

and out the back isolates the probably

CPU liquid cooler if that's what you're

using it for. The biggest challenge for

something like this is going to be one

half of this chamber space is kind of

taken up by the fan itself, the fan

frame. Uh and then the other one is just

sitting the fan inward. Obviously

there's reduced access to air from the

outside and so this is why Le has angled

it. Yes. So it gave us a directional

Yeah. to because it's negative pressure.

>> Did you try this in other angles or

>> Yeah, it was originally flat but because

the well if it's a cross flow work,

right? But if it's because the fan

nature is like they try to pull in air

from just one direction,

>> right?

>> And then

>> cross flow seems like it would have

pressure issues with the radiator.

>> Oh yeah, I think it's the area.

>> Area definitely makes sense. Yeah. Yeah.

Yeah.

>> So what what was the difference like

going flat versus angling it a little

bit? Oh, huge, huge, huge.

>> Yeah. Yeah. If you do like smoking test,

Yeah. you can obviously see that. Yeah.

>> Yeah.

>> I think it's a similar uh idea of like

we angle the the fan on the bottom.

>> So, we if you if you just make it flat,

>> flat on flat on this would be pretty

bad, right? Like cuz it's so low. So,

making it angled makes sense. Yeah.

>> Making an angle. So like we can tell uh

if I we have like a piece of paper here,

you'll get stuck in all the way,

>> right?

>> It's because this is on the angles. So

you get the intake have uh directional

effect.

>> Right. Right. UX100 also just a top

level. This this is a $100 case. Lean

was originally planning to do some kind

of like OEM SI type of thing. They ended

up liking it enough to try and sell it

as a standalone DIY part. So you can see

the cut across section here. This is a

lot different from the Montek one where

like that's that's

pretty strong I feel like. Do you have

steel in here?

>> Yeah.

>> Yeah.

>> Yeah.

>> So the Monte one we were looking at they

have a socketable name plate as like a

wedge to help support it because it it

was kind of wobbly. So um so anyway, I

think this this seems to be like a meta

that we're going to see pop up this year

at Computex. the side plate uh light

panel is not included. That's an option

they're doing. And then otherwise the

sort of main aspects of the case are

moving the motherboard tray in such a

way that it pushes the GPU forward more

in the glass so that you can see it from

this third angle here and uh and then

getting it right up against the bottom

fan intake. So the the power supply is

also rotate uh 90°. The reason being is

that uh we want to clear out the entire

front for air intakes and then we don't

want the cable to stick out because

otherwise like you wouldn't looks good

in the front. Right.

>> Right. So the power supply is purposely

re rotate. That's why we need uh another

um you know cut out here just to have

the power supply to exhaust air.

>> The Land Cool 4 I really liked. Uh did

you first show it one year ago or two?

>> Uh I think one year ago. I think you

first show it at complex you know the um

>> cuz I think that the design well design

is very

>> it's very bold you know cuz you uh stuff

in the fan in the middle of the glass

and then it's we try different iteration

because

>> uh when we create products we want as

many people to like it. So this time uh

we make some adjustment on the PSU

shroud. Uh this is the design that we

show at CES.

>> Uh some like some does not. That's why

like we

>> we did this separate compartment I

guess.

>> Yes.

>> Yeah. So this design when I was looking

at it earlier basically this lower fan

when it's oriented with the lower

chamber like this, it's there's like no

real way to to move the air up into the

case. So what they're doing is they're

shooting this air into kind of like a

duct. I guess it's right here. You can

see it easier. So, this is at the front

of the case. Uh, air is going to shoot

in there from that lower fan and the

glass. And then as that travels in, it's

going to get pushed up through the fans

mounted to the shroud top and into the

GPU. So, that's kind of the layout. Um,

this is supposed to come with three

front fans. These are 140s. Technically,

they're circular, but and then a 140 in

the back. Um, Ly also wants to include

$130. We should It's worth maybe briefly

talk about this again. We did this last

year, but the the challenge with putting

fans inside of glass, I would assume, is

that glass breaks?

>> No, not so much a glass break. It's the

>> it's the after service, you know.

>> Oh, yeah. Okay.

>> Yeah, cuz we have to keep uh supplying

this because this is a non-standard fan,

>> right?

>> Cuz uh the normal standard fan would

looks really bad on this. Well, we

>> do. You have to use thicker glass to

accommodate this without problems? Uh,

not really. It's the it because if it's

too thick,

>> you wouldn't be able to bend like this.

>> Oh, right.

>> Yeah. And also, I think the the key the

key tricks is that when they need to cut

holes and bend at the same time, they

have to make sure there are some safety

distance between each holes, right?

>> Otherwise, you wouldn't be able to make

it, you know. Yeah. Like you said, like

if you make it the two holes were too

close to each other, this glass will

easily break.

>> So, then user serviceability.

Did you end up getting this to a point

where it's easy for the end user to just

remove it and replace on their own? I

guess

>> uh

>> like if they have one die or something.

>> I mean if we this if this is ending up

at the markets then we will like having

this give you the longer warranty.

>> Mhm.

>> Yeah. So whenever it's go bad and then

we just help to replace.

>> Any idea what the warranty might be?

>> I don't know like 3 years.

>> Okay. Yeah. For a case. Yeah. Not bad.

>> Yeah.

>> Yeah. Cool.

>> Um yeah. Yeah. So that that kind of

wraps up the Lancole 4 and we covered it

last year in relative depth, but I guess

>> the main differences are the the way the

chamber's laid out. The screen is not

included.

>> Yeah.

>> So last one on the case side we'll kind

of talk about is the V2000, which this

is on the more expensive side of cases

this year for them. So $240. Um really

the interesting part is this panel. Does

this just pull? Yeah. Okay. So this

panel is an interesting mesh where it's

like basically woven steel. So you look

kind of closely. It's over under over

under the repeating. Um and when we were

talking about the manufacturing earlier,

this as I understand it is made in one

gigantic sheet and then the factory cuts

it to the size that that you would use

as the the buyer. Yeah.

>> Um I I asked you where does this type of

weave normally get used? Like what kind

of cuz I don't think I've seen this in a

computer case before.

>> It was probably used in the um like

someone's house. They wanted to do like

um uh security shielding for the window

or something.

>> Uhhuh. It's funny. Yeah.

>> And this is just a steel.

>> Yeah.

>> Um so gives massive holes for intake. So

really most resistance is going to come

from the filter rather than a double

stack like mesh and filter.

>> Yeah.

>> So So that was kind of interesting just

because it's like a new I I have not

personally seen this on a computer case.

>> Um these are not 5 and a quarter drives.

I thought they were.

>> Yeah. These are the covers. Uh they're

>> just covers.

>> There are covers because you can modify

this to uh full 120.

>> Uhhuh. So and then obviously that would

be u that would be extending out uh to

top and bottoms and this would help to

covers up so that the help with the air

flow when you do that prevents back

circulation right uh and then the last

thing interested on this case I mean

it's it's just it's a big workstation

box you know it's got the GPS support

and all that stuff like I'm not as

interested in that but uh this is like a

I don't know what's this is like a

semi-transparent aluminum or something

>> yeah they have to you know if I do some

sectional laser edging. Okay.

>> To make the the section very thin so the

lights can travels

>> and then we put like a digital display

right behind it. Yeah.

>> So are they lasering the aluminum just

where the display is going to be

basically?

>> Yeah.

>> And then it's a digital display I guess

behind it.

>> Yeah.

>> That's funny.

>> Is this a pain in the ass to make?

>> Yeah, it is. We still looking to see how

well the um the technique can work out

because right now like it it's not as

clear as we want it to be.

>> So we definitely need to go back and uh

check with the manufacturer to see if

this is possible to make it even thinner

so that the light can

>> u shines a bit better.

>> Uhhuh.

>> Yeah. But the idea is that um because

this display like someone needs it,

someone doesn't. Uh, so

>> so if it's off, it just looks like

aluminum. Exactly. Okay. Yeah, that

makes sense.

>> Yeah.

>> Yeah, that's kind of fun.

>> All right, show me your magic tricks.

You Every year you have magic tricks.

Last year it was wireless fans.

>> Yeah,

>> that you I asked you why why would you

need a wireless fan with a battery and

you said the flex on people.

>> Oh yeah.

>> So this year, let's let's do this one

first. What's going on with Walk me

through

>> Yeah. Uh

>> so this is a motorized uh AIO pump head.

So basically uh a curve screen is um is

a new trend for an AIO. Uh LCD is quite

adopted and then now for higher end

audience

>> they will want something that is unique.

But the problem with the curb screen is

that uh you always feel it at this

default angles

and if you do have this default angles

sometimes it's hard for example for me

to look at this angle I only see like

40% of the screen right but

>> was this was this your idea or someone

else on the team I'm just curious

>> it's my idea but they helped to figure

it out

>> yeah my engineer asked me

>> why don't you just make it you know um

you know hand rot able,

>> right? Uhhuh.

>> But it's like

>> what was your answer?

>> Well, me personally, I think the

interaction between the machines, you

know, should be um not touched by hand,

but you can uh touch few button and it

moves, you know, it's like that to me is

an interaction with the machines, you

know.

>> Yeah.

>> Yeah.

>> So, if it's just like

>> if it just like you have to open the

panel all the time to find the angles,

then you wouldn't want it to use it

later on. But if I can make it, you

know, controlled by software or button

or something, then you can play around

later on, you know.

>> How how good is the endurance on the

motor and the gears?

>> I mean, we will make sure like uh it's

we can you can do it like few thousand

times. Yeah. Yeah.

>> You have to use I guess you use like a

steel or something for the teeth or do

you know yet? Not sure yet. For the

material I mean internally.

>> Um so basically for the up and down

>> Mhm. Um you there is like air the

there's like um guides, metal guides. Um

so you see two sides, right? So that's

that's handles the lateral movement,

>> right?

>> Yeah. And then there's I don't know if

we can see it on camera, but there are

gears in there.

>> Yeah.

>> Uh up in the top it's like a white color

gear.

>> Mhm.

>> So I guess that handles the movement,

but that's fun. Okay.

>> Yeah. And then also um you see let me

show you a default position will be

around

>> here.

>> Okay.

>> And then see it almost touch the GPU.

>> Yeah.

>> And then everything it was so down there

and then it becomes a little bit empty

on top. That's why like this vertical

movement also would help you

change the look of your PC. Right. you

had um software to see the data transfer

through hubs and things like that,

right? Like through a hub like this uh

USB hub.

>> Yeah. Yeah. So,

>> so if we just look at the maybe the just

the transfer speed I guess was

interesting.

>> Yeah. So basically now this is the the

the ports that you plug in to your

motherboard and that you can consider

that as a total speed

>> but then you get transfer between each

ports on the hub

>> right

>> and then if I plug in more stuff this

windows will show basically it mean it

means like how much bandwidth you're

currently using

>> right right

>> and how much data is being sent

>> you know what would be interesting is

the USB discussion so there's There's a

USB stack, a hierarch protocol, right,

of

>> Yeah.

>> Um, who gets priority?

>> Yeah.

>> Do you want to walk me through that

again for people?

>> Yeah. So, basically, uh, most of the

time we were plugging the, uh, 2.0 or n

pin headers into the motherboard but but

because like uh those are also part of

the USB control on the motherboard but

it sits a very uh mid to low uh tier on

performance and and priority right

>> um of the entire USB tree right but if

you want like a direct access from the

CPU it's the 3.0 that is uh having that

uh possibility that's why like for the

new hub we also that user plug the 3.0

so we have a split splitter so because

the case also come in uh the 3.0 headers

right so 3.0 headers will plug to the

splitter and then we use that uh so we

occupy one of the 3.0

>> let's get a shot of it the

splitter you're talking about the pass

through

>> so basically this is a splitter so this

is your 3.0 0 headers from the case. You

plug in this and then this goes to the

case 3.0 headers and then that to the

hub,

>> right? So, you still get your front

panel USB, I guess.

>> Yes. It doesn't really interfere even if

you try to plug something uh onto your

front.

>> And then that that elevates uh in the

USB

>> priority priority. Okay, cool.

>> Um let's look at one last thing, which

is the you can lead the way to your fan

room. Every year I feel like you're

you've gone total mad scientist with

trying out new fans.

>> Yeah. Well,

>> so what what is it? Why do you

>> what makes them so interesting for you?

>> Um I think solving problem actually.

Yeah. Cuz you know I think RGB is

you know it becomes a lifestyle almost.

>> What are you loving?

>> That is that is a

>> it's um

>> a wonderful Yeah. It's a lifestyle

thing.

>> Lifestyle. Yeah.

>> Everyone wants the Everyone Everyone

wants, you know, their own colors, their

own content on the screen and just to

show

>> your personality. I mean, PC is not just

about having it to run games,

>> but also it's

>> reflects you. Exactly. Yes. And then uh

we always wanted to, you know, create

something that people can um create

their own, you know. So and through that

process through that process then we

have feedback about what is the things

that people don't like and then what is

the people likes and then we just keep

improving improving improving. Yeah.

>> Right.

>> So this was kind of interesting. I know

you have a lot more here but we'll focus

on this one. Um walk me back through I

guess the demo you were given earlier.

>> Yeah. So um throughout the experience of

selling this um LCD fans, we found out a

lot of the users that um even though

like they bought the LCD fan, they just

use our preset you know the preset that

was originally from the software

>> meaning they don't upload their own

>> they don't upload their own you know at

least like cuz some of the people would

buy at least uh two groups of fan and

then that's about like six screen but

>> uh at least half of the screen they will

just use the preset to have the

temperature sensor and then the

background that we already made on the

software.

>> So that's why like uh this idea comes to

my mind like

>> um we can figure out ways to use the

features that they use to use but

>> uh to but decrease the amount of cable

they need to plug.

>> So this right now you see uh it's only

plugged into the power

>> but it's just PWM.

>> It's just PWM. Yeah,

>> but I can still

goes in here.

>> So basically what you're getting at is

there's no USB, right?

>> Yeah, there's no USB.

>> Okay. So there's no data connection.

>> So you see how I still can

So you see how many presets that

>> Yeah.

>> He has.

>> So these are built into the software.

Okay. So how So is it

>> So this is not built in the software.

This is built in because this presets

Oh,

>> is it built into the fan?

>> It's built into the fan.

>> Okay. So, the fan has flash storage.

>> Yeah, a storage has flash storage. So,

>> okay.

>> So, about like 30 templates?

>> Yeah,

>> 30 templates. It's already inside uh

>> in the in the fan. In the fan. So, is

the is the flash does each fan have its

own flash? I guess in the hub area.

>> Yes.

>> Okay. How much flash is it?

>> I think it's uh 512 megabytes or

something. Okay.

>> Yeah. Funny. So, okay. So, then

for data without USB, is it wireless?

>> It's wireless control. So, it's the

controller right here.

>> Uhhuh.

>> Yeah. There's a controller right here

that it uh still sends the uh

temperature readout,

>> right?

>> To the receiver and the receiver will

show.

>> Okay. And I guess does the factory just

uh just write the data to the flash as

they're manufacturing it? So you send

the factory the files that you want to

be on the flash and they

>> and then the interesting aspect is like

um later on we can still send out you

know a firmware file and the user can

use the USB to flash the firmware

>> so that they the content that they don't

want they can replace with different

files.

>> Okay.

>> Yeah.

>> Right.

>> Obviously you can still go with the USB

do customization on their own

>> but this is just an example where we try

to solve problems you know.

>> Yeah. Yeah. That's cool. What about if

if

>> in the bootup process, you're probably

not initialized yet, right? On the

wireless

>> Yeah.

>> transmitter receiver. So,

>> let me change to the theme that has uh

temperature.

>> Okay.

>> Yeah. So, that because that was a clock.

>> Yeah.

>> Okay.

>> So, you're changing the screens to be

temperature. Okay.

>> Because all the templates it's already

inside the flash.

>> Mhm. And then once I hit the com I set

up the comments, it remembers it. But

because uh like you said during the

brute process, the the wireless control

will not be

>> initialized

>> visualize. So you will not have the

temperature readout, but instead

it reads the RPM.

>> Okay.

>> Of the screen.

>> Got it.

>> Yeah. See that one?

>> Yeah. Okay. Over here. Uh-huh.

>> Yeah.

>> Yeah. Cool.

That's neat. Yeah,

>> it's a surprising amount of engineering

that goes into

>> Yeah.

>> fans, right? That's pretty cool.

>> Awesome.

>> I think that walks us through pretty

much uh everything I wanted to cover.

You I know you have a lot more, but

every year it's there's a lot of the

Lee. So, um yeah, that'll be uh we've

got a ton coming up for the show for

Comput text. So, check back as always
