Solving the GPU Airflow Problem | Bouncing Air in the HAVN HS 360
344 segments
Okay, we have one of the most
complicated cases for Computex. This is
the HS 360. This is from Haven. So, what
Haven's done is actually amusing, I
guess. I It should work pretty well, but
basically, there's another glass sheet
up here. Now, this sits on top of the
GPU. You can see that rubber sort of
bumper at the end that's uh allowing it
to almost directly contact the GPU. And
then if you look at the bottom front of
the video card, it's directly contacting
that glass sheet. So what's happening is
if we spin to this uh CFD simulation,
this computational fluid dynamic
simulation, it it all makes sense. This
is really fun. Like this is just it's
kind of fun science where basically what
you have is uh without the glass flow
separator here. So that's that new
piece. This is the one that previously
existed on the BF3 or the HS420, the
original HS420. Uh, and that's present
here as well, but you can see they've
added the glass separator. And then this
is the same thing, no glass separator,
still has that HS420 style uh,
deflection. And then this is with the
glass separator. So basically what
you're seeing is at least in simulation
we'll you know this is going to depend
kind of build to build um and we'll test
it but in simulation the uh for this the
hot air if you're at 100% GPU fan speed
which is very uncommon but good for kind
of a demo uh it's shooting all the air
up and out or out the bottom because the
fins are oriented vertically and then
that is getting pulled back into the
fans at that 100% speed without a flow
separator. This makes sense. This is not
like new. This isn't, you know,
revolutionary science. This is just how
it normally works. Uh, with a 55% speed,
it's kind of a different problem where
for this, still hot air exhausting top
and bottom, but the fans on the GPU are
lower speed. So, they're less likely to
pull that air in and recirculate it. And
instead, it's it's going up and out. So,
this is just a difference of positive
versus negative pressure setup for the
case, or at least for this region of the
case. And the end result is the cool air
coming in from the bottom for this one
is sometimes circumventing the GPU is
not getting pulled in. We talk about
this a lot in our testing. So you can
see this stuff in data like in thermal
data with results and we show that uh
but the simulation helps make clear kind
of what's happening. And what'll be
interesting for us to test is with this
flow separator in the two different
conditions, you when you have the
problem of the hot air getting
recirculated, this will block that
obviously cuz looking back at the card,
you these fins, they're set back towards
the CPU cooler. They're oriented
vertically. Most fins are on GPUs these
days. And uh they it's just it's not
going to be able to get back down
because there's a piece of glass
blocking it. Um other than maybe a
little bit at the back or something. And
then under the the lower flow uh
situation where it's like 55% speed
which is pretty typical for most GPUs.
Um I think we set ours to that for our
case testing in that condition. It's uh
the difference of where the the cool air
here is actually just getting blocked so
it's not going up and out and it's more
forced into the card. Pretty cool stuff.
I just I thought it was neat to see the
simulation of it. Uh we'll do the
testing of course, but that is the big
thing that Havens tried to do moving
from the HS420, which is a much larger
version of this case, uh to the HS360.
It was basically like instead of getting
rid of the concept in its entirely
entirety, let's double down and put
another piece of glass in the case. So
now we can have the full curved glass
front, the glass deflector, and the
glass separator. uh they are really
determined to make this idea work. So,
I'm looking forward to testing it, but
that's the big change. Um there's a
bunch of others, too. We'll go through
them all. Before that, this video is
brought to you by Arctic and their MX7
thermal paste. Arctic's new MX7 is a
higher viscosity paste with Arctic
claiming that the increase in viscosity
from filler content and the texture
benefit improve its performance while
reducing the risk of the pumpout effect
over time. MX7 is intended for longer
endurance applications and to be left
and used for extended service life.
Arctic also now has a counterfeit paste
checking website because believe it or
not, knockoff paste from non- firstparty
sources is actually relatively common
for the big brands to experience. So,
they have a site to check the validity
of it. Get a tube of Arctic's MX7
thermal paste at the link in the
description below. All right, so the HS
360 is a relatively difficult case for
me to memorize and go over at a show uh
because there's a lot going on with it,
which is a good thing. But the Haven
series cases, we've overall been
positive on the BF360 and the HS420 both
overall tested pretty well. We did
obviously have various criticisms of
them like every case. One of them was on
the HS420 it was a I think the technical
term is gigantic pain in the ass to deal
with the fan in the back of the case and
they have fixed that. So, this is just a
fan mount or bracket that goes in the
back here. And, uh, rather than having
to, uh, be careful about what order you
install the rear fans in, now you just
access it from the backside. So, that's
a lot better. They're still doing the
thing that they did with the previous
cases, which is putting rubber at
basically every single contact point of
the case, where metal might touch metal.
There's rubber all over the place. So,
that's something we've been positive on.
We've liked with the Haven cases. It's a
really small touch. Um I don't know,
maybe like sometimes it might help with
vibrational noise. It's more of just
kind of a nice uh attention to detail
thing though. And then some other
improvements and changes. Um so the was
it over here on the So we did talk, this
is on the previous uh case that we
reviewed, but I did just want to give an
update for everyone. Previously
we did talk about the recommended uh
cable paths and they have fixed that. So
so Haven has just been working really
hard at improving everything that we've
criticized from from spelling to the
mechanical design. Um some other
interesting stuff with this. So for the
new case, this is their attempt at
trying to solve the fact that anyone who
supports both a back connect board and a
standard board uh ends up creating a
cheese grater motherboard tray. And uh
basically you can see the kind of the
holes for both here. So this is what
everyone's shipping when they try to
support both. Looks kind of ugly. And
they're just doing a separable plate.
Now this is currently done with a bunch
of screws. I would love to see this
implemented in a way where there's a a
simple mechanism either it's you know
plastic clips or metal socket and ball
or whatever um to get it to be a little
quicker to pull out. Now you should
probably only be doing this once as an
end user but uh it would be nicer.
They're going to ship this in a standard
configuration by default. And then if
you want a back connect, you would
basically pull it out, flip it like
we're doing here, and then that would
give you the the whole pattern without
having holes through the entire
motherboard tray. Um, and then there are
the grommets that we've also come to
expect from Haven. So, they've got kind
of the stringy kind where you can run
the cables through them and separate
them. Uh, those can go in if it's
standard layout. If it's back connect,
you probably don't want that for obvious
reasons. Um, but those come out with
back connect and then they also have
these cable combs that uh that go in the
case, too. So, a lot of really small
like attention to detail touches.
Pricing on these is supposed to be $150
for base and then $230 for the vertical
GPU model. Uh, and then there, this is a
different case. is this HS420, but um
this is also going to be in the uh uh
upper 200s for the technically not
Mercedes I guess a AMG Patronis Formula
1 team. I've been told in no uncertain
terms that I am not to say that this is
a Mercedes collaboration. This is not a
Mercedes case.
This case with that logo is not a
Mercedes case. It is an AMG Patronis
Formula 1 team case. I hope we are all
clear that this is not a Mercedes case,
especially the lawyers at Mercedes.
Okay. All right. So, another thing that
Haven's working on is on the mechanical
design where uh this corner, they wanted
to strengthen that. And if you look
internally at the older HS420 here, the
main thing to notice is that this is
just kind of a flat bar for this top
corner. Um there's been some changes to
the way the panel secures, too. on the
new HS360.
This is a far more complicated uh set of
steel here. So you can see it kind of
bends and this like punched out section.
Uh all of this is intentional where they
say it's basically meant to improve the
structural strength. So Haven ran these
simulations as well where this is a
force application scenario. So this is 5
kg uh of force pushing down on that
front edge without a glass panel
underneath it. So without any support
under that front corner. Um, and then
what you're looking at is deformation.
So this is in millimeters deformation.
This is pretty cool, uh, from a software
standpoint. So they're seeing like
almost.5 millimeters of deformation on
the old design with the HS420. And then
the H360, which is the new design that's
got that reinforced
uh, piece underneath the uh, the fan
tray panel. There's, you know, 0.3 mm
deformation max. So pretty cool stuff.
It's like this is what we liked with the
BF360 announcement last year at Computex
was having some actual data available.
We can go through some of the other
stuff. So on this one where they were
doing the simulation of flow, uh the big
thing to notice on the right side for
the GPU fans at 55%. The GPU temperature
is 60.2° without the flow separator,
52.7 with it. So that's pretty big
difference. It's like 7 degrees is a
gigantic difference for a GPU. At the
100% fan speed, they're not really
seeing any difference, which I would
expect just because uh when you're
blasting the fans that much, you're kind
of overpowering a lot of the um more
nuanced differences anyway. And then on
this one, so this is a liquid cooler in
the HS 360 with a VGPU
and uh I've seen a couple degrees of
performance or one almost two degrees of
performance improvement. noise
normalized on the left image with the uh
with and without the flow separator. And
then for the HS420, they also did
testing with the flow separator, even
though the focus today is on the 360,
but see it added here. That improvement
is pretty big. Then Haven says they are
planning to do a flow separator as a
separate component for the HS420s in the
future. So this is Haven's uh
competitive analysis chart. These are
not necessarily the cases I would choose
to compare against. The Corsair 3500X
sucks. Uh the Lean Lee 011 is old and
the NZXTH9 is from NZXT. Um so we would
compare against probably different
cases, but at least versus this Eclectic
mix, they you know they're showing well.
We'll we'll test that in our own
benchmarking of course, more noise
stuff, but anyway, that's kind of some
of the basics on the data. Um the plan
for Haven is they want to launch around
September for the HS360
and uh pricing as I said is 150 base no
fans um or 230 for the VGPU option which
uh we tested both the VGPU and the base
models for the HS420 if you're curious
how that kind of all looks and works.
But the general design, I guess, look is
very similar to the uh the past cases
where they're still doing these really
large um slats. And on on the past Haven
cases we've looked at, the spacing for
the uh supports has typically been
pretty good in terms of especially on
the side panel in terms of minimizing
how much overlap you have for the
support on top of the fan blades. So,
that's been one of Haven's strong points
is trying to align like on the side
panel the supports with the fan hub
where the hub is a dead zone for fans.
You're not going to get really any air
going through there. Um, and that's all
been kept with the newer case. So,
mostly just updates and refinement for a
smaller uh HS series case that they are
taking some some learnings from and
improving on. I think we've kind of
covered most of it. The rest of this
stuff is I mean it's like the same as
the past with the uh drive cages that
can mount on the side versus a a cooler
fan. So, um I think that pretty much
covers this stuff and otherwise we're
looking forward to getting the 360 in
for testing. Uh there's going to be a
lot of AB testing to do with the
separator and the glass. I think that
pretty much covers it though. So far, we
haven't seen a ton of cases yet, but out
of the ones I've seen, this is the most
interesting one to me. So, we'll see how
the rest of the show goes and check back
for more. As always, uh subscribe for
the rest of the news. will be here all
week and we'll see you all next
Ask follow-up questions or revisit key timestamps.
The video highlights the new Haven HS360 PC case, focusing on its innovative design choices, particularly the inclusion of a 'glass separator' meant to improve thermal efficiency by preventing hot air recirculation within the GPU region. The host details various mechanical refinements over previous models, such as improved rear fan access, increased structural strength, and modular motherboard tray designs. The case is scheduled for a September release with pricing starting at $150.
