00:00:00.080 --> 00:00:08.480
we're here at CES 2025 to look at this

00:00:03.760 --> 00:00:10.759
Dell Pro 14 premium now it looks pretty

00:00:08.480 --> 00:00:15.839
standard from here although if you look at it from this angle you can see that

00:00:13.120 --> 00:00:21.320
it's Slimmer than any other one that has ever been made and that is because this

00:00:18.520 --> 00:00:27.760
particular example does not have a single fan in it but it's not fanless

00:00:23.640 --> 00:00:30.160
well it is but it also has ice as in an

00:00:27.760 --> 00:00:36.320
ion cooling engine let's have a look at in this is the ventiva ice 9 and if you

00:00:33.360 --> 00:00:44.120
look really really close there is a super tiny wire right here and across it

00:00:39.760 --> 00:00:46.079
they put 5,000 volts now before we get

00:00:44.120 --> 00:00:50.840
into the science of that you might be a little bit concerned about having 5,000

00:00:48.160 --> 00:00:54.920
volts just in your laptop but don't be concerned the current limits are super

00:00:52.680 --> 00:01:00.039
super small so if you touch it you'll get a tiny bit of electric shock but it

00:00:57.440 --> 00:01:04.799
will not be harming you what that 5 th000 volts does is ionizes the air

00:01:02.719 --> 00:01:10.040
giving it a positive charge and then this area in the back is grounded which

00:01:07.520 --> 00:01:14.000
is effectively a negative charge this means you know positive attract to

00:01:12.159 --> 00:01:20.840
negative air goes out the back of your laptop and becomes nice and cool this

00:01:17.560 --> 00:01:22.880
guy right here is capable of about 8 CFM

00:01:20.840 --> 00:01:28.159
which is similar to what you would find in a typical thin and light laptop fan

00:01:26.079 --> 00:01:32.200
now I did ask them if it's possible to just throw More Voltage at the the

00:01:30.119 --> 00:01:38.360
problem and get more air flow out of it but it turns out that the limit of this

00:01:34.520 --> 00:01:40.280
is actually the breakdown of the air so

00:01:38.360 --> 00:01:45.759
at a certain point this stops becoming ionizing air and you get lightning in

00:01:43.000 --> 00:01:51.399
your laptop which is obviously not very ideal so physics kind of has them a

00:01:48.920 --> 00:01:56.719
little bit constrained but fortunately space doesn't necessarily they have a 40

00:01:54.520 --> 00:02:01.119
W solution right here because of the size of it it actually works really well

00:01:58.799 --> 00:02:07.280
with typical heat sink designs like you think of it a fin stack is always thin

00:02:04.240 --> 00:02:09.599
long that sort of a shape a fan is a

00:02:07.280 --> 00:02:14.959
square so if you can instead have a little ion driver chummy that is there

00:02:12.959 --> 00:02:20.640
instead it's much more convenient for the design of your thermal solution one

00:02:18.200 --> 00:02:29.000
problem though is that the static pressure of these is uh not not good at

00:02:24.920 --> 00:02:31.959
all it's very very bad the poor air flow

00:02:29.000 --> 00:02:37.959
though is not really vena's problem in this case it is Dell's so they have been

00:02:35.560 --> 00:02:43.159
actually working with Dell and Intel to help Design This which is incredible I

00:02:40.800 --> 00:02:47.280
cannot believe that oems are already on board with this but basically they've

00:02:45.159 --> 00:02:52.720
redesigned how the vents are put in the bottom of the laptop to optimize for

00:02:50.040 --> 00:02:57.080
very low static pressure and high air flow which allows us to have very

00:02:54.680 --> 00:03:01.760
similar performance to a laptop that has traditional fans in it and it also even

00:02:59.360 --> 00:03:05.319
means that can be thinner because you don't need the air gap that a

00:03:03.080 --> 00:03:12.239
traditional blower fan does need over top of it very cool now why would you

00:03:08.319 --> 00:03:14.640
want to do that well very simple sound a

00:03:12.239 --> 00:03:21.640
typical laptop like this might be somewhere around 28 DB around there is

00:03:19.000 --> 00:03:25.840
whereas with the ventiva ice it's able to get down to

00:03:23.319 --> 00:03:31.439
14 I can almost guarantee you that whatever room you are in right now is

00:03:28.239 --> 00:03:35.159
way louder than 14 DB for some context

00:03:31.439 --> 00:03:36.760
of how absurdly quiet 15 DB is we have

00:03:35.159 --> 00:03:43.360
put a bunch of work into creating an acoustic chamber at our office and that

00:03:39.000 --> 00:03:46.400
is able to get about like an 18 D noise

00:03:43.360 --> 00:03:49.000
floor meaning that even with as much

00:03:46.400 --> 00:03:54.200
isolation as we can put into that little room we still would not be able to hear

00:03:51.519 --> 00:03:58.720
this thing it is so quiet only the air moving through the fins creates a noise

00:03:57.000 --> 00:04:04.640
two problems though if they want to make this an actual product first of all

00:04:01.360 --> 00:04:06.640
powering the thing it's 5,000 Vols so

00:04:04.640 --> 00:04:11.519
that can be an issue and the second is it might be a bit toxic we'll get to

00:04:08.799 --> 00:04:16.840
that in a bit first of all the power so this right here is a pretty typical

00:04:14.280 --> 00:04:23.000
stepup converter basically you go from 5 Vols to 5,000 using just a whole bunch

00:04:19.799 --> 00:04:26.880
of little Electronics in there this one

00:04:23.000 --> 00:04:28.960
as it stands is about 60% efficient and

00:04:26.880 --> 00:04:34.560
that Nets you compared to a normal fan something like minus 20% efficiency now

00:04:32.360 --> 00:04:38.600
Dell says currently that's about a wash for power because since it is smaller

00:04:37.000 --> 00:04:42.759
than a traditional fan they can add in more battery but at the same time

00:04:41.000 --> 00:04:47.759
theoretically this could be more what like 80 to 90% efficient and they do

00:04:45.680 --> 00:04:52.039
think that they can get up to around there which would bring it just about

00:04:49.639 --> 00:04:58.160
even with the efficiency of a typical computer fan the second problem toxicity

00:04:55.720 --> 00:05:02.880
and speaking of which dbrand is very toxic on Twitter that's the segue to our

00:05:00.560 --> 00:05:07.160
sponsor spot our CES coverage is sponsored by D Brand's new ghost case

00:05:04.759 --> 00:05:11.440
2.0 have you ever owned a clear case that looked like this well with the

00:05:09.160 --> 00:05:15.160
ghost case 2.0 that's literally impossible dbrands words not mine in

00:05:13.759 --> 00:05:18.759
fact they're so confident about their zero yelling guarantee that they'll

00:05:17.039 --> 00:05:23.160
literally give you a free replacement for life if it ever turns yellow now you

00:05:21.280 --> 00:05:27.280
may have heard that clear cases can scratch pretty easily in fact dbrand had

00:05:25.759 --> 00:05:30.919
that exact problem with their original 1.0 version of the ghost not anymore

00:05:29.479 --> 00:05:34.919
though they have spent over a year developing an allnew scratch resistant

00:05:32.759 --> 00:05:39.120
coding and replacing every single ghost 1.0 customer for free that's how we got

00:05:37.479 --> 00:05:43.120
this one right here so if you want to get the Holy Grail of clear cases from a

00:05:41.240 --> 00:05:47.560

00:05:49.120 --> 00:05:56.479
sponsoring this video okay back to the toxicity thing now when we are ionizing

00:05:54.639 --> 00:06:00.960
air one of the things that is in air quite an important part of it is oxygen

00:05:58.520 --> 00:06:05.319
and oxygen is two oxygen molecules that are together you ionize it boom they go

00:06:03.479 --> 00:06:11.639
apart now you have oxygen and another oxygen just o1 the problem is is that

00:06:08.919 --> 00:06:16.960
sometimes it likes to create o03 which is Ozone and which is not particularly

00:06:14.680 --> 00:06:21.280
good for you now in higher quantities ozone can be toxic you could never

00:06:19.199 --> 00:06:27.240
create a toxic amount of it out of one of these guys but at the same time it

00:06:24.199 --> 00:06:29.599
smells you only need a very tiny bit of

00:06:27.240 --> 00:06:34.520
it for it to be smelly cuz our noses are excellent at their job to combat the

00:06:32.000 --> 00:06:39.280
ozone they have actually coated the fins in the heat sink with maganese dioxide

00:06:37.639 --> 00:06:43.919
that acts kind of like a catalytic verter in your car which takes the ozone

00:06:41.639 --> 00:06:49.360
and allows it to easily go back into the O2 that it wants to be even if you just

00:06:46.880 --> 00:06:54.560
have ozone normally in your house it will break down in 25 minutes or so that

00:06:52.520 --> 00:06:59.000
is the halflife so you don't really have to worry about it but you don't want

00:06:56.360 --> 00:07:03.400
your laptop to be smelly one other thing that I was a little bit curious about

00:07:01.120 --> 00:07:08.199
though is dust it seems like that if you have just this tiny little wire in there

00:07:06.520 --> 00:07:13.680
it could be very prone to getting clogged up and of course it is not

00:07:10.199 --> 00:07:16.360
impervious to dust but interestingly it

00:07:13.680 --> 00:07:20.599
can also detect dust now they won't tell me exactly how it works trade secret

00:07:18.800 --> 00:07:25.759
crap but apparently the electrical characteristics of this wire will change

00:07:23.720 --> 00:07:31.120
as dust gets attached to it and they can actually create a report of how much

00:07:27.800 --> 00:07:33.479
dust your laptop has in intake and also

00:07:31.120 --> 00:07:38.639
Dell apparently will just not make a laptop if it gets dusty and stops

00:07:36.479 --> 00:07:43.160
working I asked them about how they do it and I guess they have just a chamber

00:07:40.520 --> 00:07:47.599
that is filled with cat hair and dust and they just shake a laptop around in

00:07:45.240 --> 00:07:51.960
it for quite a while and if it stops working they don't sell you that laptop

00:07:50.120 --> 00:07:55.400
makes a lot of sense another thing you might be concerned about is

00:07:53.199 --> 00:07:58.879
upgradeability but fortunately that's very simple there's a screw right here

00:07:57.120 --> 00:08:03.199
and a screw right there and then you pull on this and it doesn't come off cuz

00:08:00.840 --> 00:08:07.479
it's glued down in this prototype but in theory you could just take this top

00:08:04.720 --> 00:08:12.319
cover off swap out this component right here and then boom you have a working

00:08:09.759 --> 00:08:18.280
not fan fan once again and another thing is just the cost now of course they are

00:08:15.639 --> 00:08:22.319
absolutely nowhere near the economies of scale that you have with fans fans have

00:08:20.560 --> 00:08:26.720
been around for a very long time and unsurprisingly people have gotten very

00:08:24.400 --> 00:08:32.080
good at making them for cheap but that said these right here are very uncom

00:08:29.479 --> 00:08:36.360
licated it is a wire and a little bit of stamped metal so this portion right here

00:08:34.519 --> 00:08:41.360
should be quite cheap although that said you do still need a PCB and a bunch of

00:08:38.800 --> 00:08:46.519
electronics to get it up to 5,000 volts so they don't expect it to ever get

00:08:44.080 --> 00:08:53.399
below the cost of a fan but it should be able to get pretty darn close and again

00:08:50.160 --> 00:08:56.000
I just want to talk about how absolutely

00:08:53.399 --> 00:09:00.640
stoked I am about this not just cuz I have a cool engineering sample thing

00:08:58.320 --> 00:09:04.760
here I've seen loads of weird engineering samples and again the thing

00:09:02.880 --> 00:09:09.160
that makes me the most excited about this is the fact that ventiva aren't the

00:09:06.800 --> 00:09:14.040
only ones that are excited about it this is a real proof of concept that was made

00:09:11.320 --> 00:09:18.200
in collaboration with Dell and Intel has also been putting a lot of engineering

00:09:15.760 --> 00:09:23.120
behind getting it integrated and just generally testing it with their designs

00:09:20.880 --> 00:09:27.000
that means that it isn't just them looking for it but there's a good chance

00:09:25.560 --> 00:09:33.399
that you might actually have a Dell laptop in the future that has no stands

00:09:30.399 --> 00:09:35.720
but still has forced induction what

00:09:33.399 --> 00:09:40.680
would you call it but still has air flow still has air flow sure we'll call it

00:09:38.000 --> 00:09:46.160
that now one final thing here you guys get to decide who is correct the Dell

00:09:43.120 --> 00:09:47.760
inventiva Engineers have been arguing of

00:09:46.160 --> 00:09:52.399
what they should call this phenomenon there's a couple names so we can either

00:09:49.399 --> 00:09:55.839
go with kulic Force electrohydrodynamic

00:09:52.399 --> 00:09:57.600
flow ion drag or Corona wind put down in

00:09:55.839 --> 00:10:01.519
the comments below which one you think should win just like you should have a

00:09:59.880 --> 00:10:07.040
great old day huge thanks for watching this video hit like get subscribed and

00:10:03.760 --> 00:10:07.040
I'll see you later
