00:00:00.240 --> 00:00:07.200
this video was supposed to be so simple how much better is it to go from a solid

00:00:05.040 --> 00:00:12.960
front panel to a mesh front panel when you've got high-end power-hungry hot

00:00:10.240 --> 00:00:17.760
components but then we got some really anomalous data

00:00:14.400 --> 00:00:20.400
how could adding knock to a fans all

00:00:17.760 --> 00:00:27.199
over our mesh case possibly put it in a position where our GPU is running at the

00:00:22.800 --> 00:00:29.599
same temperatures as this here hotbox

00:00:27.199 --> 00:00:34.800
the only way to find out is to use our new smoke machine hit me

00:00:31.679 --> 00:00:34.800
with the smoke poof

00:00:36.320 --> 00:00:41.520
smoke me that is weak

00:00:43.040 --> 00:00:49.600
that's all it's got i told you guys to get the good smoke machine we did the other one

00:00:51.039 --> 00:00:55.840
well anyway there's a dead spot

00:00:54.160 --> 00:00:58.719
you can see it we'll get you more details in a minute

00:00:57.440 --> 00:01:03.440
and this video is brought to you by microcenter who sells of course both

00:01:00.960 --> 00:01:07.280
solid front panel cases and mesh ones so ultimately i guess they don't care which

00:01:04.799 --> 00:01:10.280
one wins which is good no conflict of interest

00:01:17.360 --> 00:01:25.119
to kick off our intended video mash versus solid front panels we turned to

00:01:21.680 --> 00:01:27.840
the nzxt h510 a case that was notorious

00:01:25.119 --> 00:01:31.600
for looking great but having very poor ventilation

00:01:28.960 --> 00:01:36.960
now to their credit nzxt did listen and gave us the h510 flow which is the exact

00:01:34.799 --> 00:01:40.560
same case just with a mesh front panel which means

00:01:38.640 --> 00:01:46.159
should be fine right just drill some sweet speed holes and bang

00:01:43.119 --> 00:01:48.479
boom you're off to the races

00:01:46.159 --> 00:01:55.200
well yes but actually no as you can see despite the flow's

00:01:50.960 --> 00:01:57.840
improved flow of air our core i9 12900k

00:01:55.200 --> 00:02:03.840
hits a hundred degrees on the package with the stock fans and even the mighty

00:02:00.320 --> 00:02:05.840
nhd15 cooler couldn't tame this 250 watt

00:02:03.840 --> 00:02:09.280
beast without us resorting to drastic measures

00:02:07.040 --> 00:02:12.720
we then swapped out the stock fans thinking maybe they were the problem for

00:02:10.959 --> 00:02:17.599
some knock to us which brought us down to 97 degrees which

00:02:15.280 --> 00:02:21.040
well it isn't exactly amazing but it did at least stop the thermal throttling

00:02:19.280 --> 00:02:25.360
that we experienced before unlocking the maximum performance potential of our CPU

00:02:23.360 --> 00:02:29.599
and demonstrating once and for all that mesh front panels are indisputably

00:02:27.200 --> 00:02:33.200
better than solid ones which don't allow any air through them no matter how many

00:02:31.280 --> 00:02:38.959
Noctua fans you install so why is this video only one third over

00:02:36.239 --> 00:02:43.920
let's talk about our GPU yeah we've got one it's an rtx 3090 and it did run a

00:02:42.400 --> 00:02:50.319
little cooler when we switched over to the flow but only by a few degrees

00:02:47.840 --> 00:02:55.360
then our 20 minute furmark soak saw temps rise steadily to roughly 79

00:02:53.120 --> 00:03:00.319
degrees on the stock fans with the solid panel and then 84 degrees with the

00:02:58.480 --> 00:03:02.640
Noctua fans and the wait

00:03:03.120 --> 00:03:08.159
i know what you're thinking that can't be right

00:03:06.159 --> 00:03:14.879
but we triple checked in both cases while the Noctua fans

00:03:11.599 --> 00:03:18.239
markedly improved our CPU thermals they

00:03:14.879 --> 00:03:20.959
actively hindered our GPU thermals and

00:03:18.239 --> 00:03:24.319
there's nothing wrong with our nfa-12s they're great fans and available at your

00:03:22.640 --> 00:03:29.120
local microcenter by the way don't forget they sponsored this video

00:03:26.480 --> 00:03:32.720
so what the devil is going on here to start our investigation we're gonna

00:03:30.959 --> 00:03:38.319
dial things back a little and use a gaming rather than a synthetic load for

00:03:35.120 --> 00:03:41.040
our test we looped our f1 2021 benchmark

00:03:38.319 --> 00:03:46.400
for 30 minutes and we got better results seeing a drop of 6 degrees on the flow

00:03:43.120 --> 00:03:49.040
on our CPU and 7 degrees on the GPU

00:03:46.400 --> 00:03:54.000
so that's a solid improvement going from solid to mesh

00:03:50.879 --> 00:03:57.760
but then again we swap to our noc to a

00:03:54.000 --> 00:03:59.439
fans and the CPU improves while the GPU

00:03:57.760 --> 00:04:03.280
heats up though at least our mesh case still did

00:04:01.680 --> 00:04:08.080
manage to see better numbers than our solid front panel

00:04:04.799 --> 00:04:10.720
guys we are running exactly the same

00:04:08.080 --> 00:04:15.360
components in all of our tests yes we built and rebuilt these pcs

00:04:13.120 --> 00:04:19.919
enough times to need some refreshing ice cold water ltteststore.com and we double

00:04:18.639 --> 00:04:22.880
checked our compatibility with microcenter's custom pc builder tool

00:04:21.840 --> 00:04:27.280
we're gonna have everything in an affiliate link down below

00:04:25.440 --> 00:04:32.880
so what is going on here let's take a look at our smoke test

00:04:29.600 --> 00:04:34.400
with our stock fan setup it's not so bad

00:04:32.880 --> 00:04:38.160
air gets pulled in wafts all around our components with a

00:04:36.400 --> 00:04:43.360
good chunk getting pulled into our CPU cooler and some circulating around our

00:04:40.160 --> 00:04:45.440
GPU then it gets exhausted out the back

00:04:43.360 --> 00:04:50.479
it's clear now though that part of our problem is this huge graphics card in

00:04:48.000 --> 00:04:54.400
such a small case it's almost right up against our fans and you can see that

00:04:52.240 --> 00:04:58.880
the air gets pulled in and hits a wall causing turbulence when we swapped to

00:04:56.560 --> 00:05:02.800
our noctuas we thought wow these things are so quiet we could spin them faster

00:05:00.880 --> 00:05:08.160
while maintaining the same noise level but get this at such a high RPM the

00:05:05.520 --> 00:05:12.560
turbulence becomes even worse and we got small pockets of air in front of and

00:05:10.479 --> 00:05:17.280
underneath the GPU that were just recirculating being heated up multiple

00:05:15.039 --> 00:05:21.440
times before going anywhere you can see our CPU cooler is still

00:05:18.880 --> 00:05:25.680
getting plenty of fresh air so it's fine better than before even but it's pushed

00:05:23.600 --> 00:05:30.240
right up against our 30-90 not quite touching but not much of a gap for air

00:05:27.520 --> 00:05:34.320
to pass through either so almost nothing is able to circulate around the GPU's

00:05:32.080 --> 00:05:38.479
back plate more fans more better though right

00:05:35.520 --> 00:05:43.280
we certainly thought so but since now we have all this air intake but no extra

00:05:40.960 --> 00:05:46.880
exhaust there's only one spot for a fan on the top of the h510 and good luck

00:05:45.440 --> 00:05:52.960
getting a regular thickness one up there with our motherboard all this extra front fan ends up doing

00:05:50.720 --> 00:05:55.680
is putting even more pressure on the top stream

00:05:53.919 --> 00:05:59.680
and since it's blowing too fast for our CPU cooler to keep up with we also get

00:05:58.000 --> 00:06:03.759
some turbulence at the top front of the case where air cycles around for a bit

00:06:01.919 --> 00:06:08.080
before it can be vented out anything trying to come up from the

00:06:05.280 --> 00:06:10.720
bottom is instead constantly pushed toward the back

00:06:10.000 --> 00:06:16.000
so in a nutshell you can pull in all the

00:06:13.280 --> 00:06:20.720
air you want but if it can't leave or if it passes over a hot tower cooler before

00:06:18.479 --> 00:06:24.720
getting pushed down into your GPU you're gonna have a pretty bad time as the air

00:06:22.880 --> 00:06:29.039
heats up inside your case obviously there are a ton of other fan

00:06:26.639 --> 00:06:33.039
configurations cases and hardware to examine so make sure to get subscribed

00:06:31.199 --> 00:06:37.120
so you don't miss our upcoming LTT Labs content where we'll be exploring this in

00:06:34.720 --> 00:06:41.120
much more depth all of the side questing out of the way though it's time to

00:06:38.479 --> 00:06:45.440
revisit our original question mesh or non-mesh

00:06:43.360 --> 00:06:50.880
we chose a bit of an extreme example as the h510 only has this tiny strip on the

00:06:48.319 --> 00:06:54.240
side for airflow but it really was a huge difference

00:06:52.319 --> 00:06:58.080
look how little air we suck in through these side vents even with our intake

00:06:56.479 --> 00:07:01.759
heavy configuration even when we blasted our fogger more

00:06:59.840 --> 00:07:05.840
directly at the side vent it hardly helped so a mesh front panel at this

00:07:03.759 --> 00:07:10.160
point seems pretty obvious but pc building is often about balance

00:07:08.319 --> 00:07:14.160
and your own personal preference the more power you're after for work or

00:07:12.319 --> 00:07:18.560
gaming the stronger the components need to be and the hotter they might get so

00:07:16.639 --> 00:07:22.000
the better cooling solution is obviously going to be the best on the other hand

00:07:20.479 --> 00:07:25.759
if you've got a pc with integrated graphics that's meant for light office

00:07:23.680 --> 00:07:28.960
work or light gaming you probably don't even need to think about what kind of

00:07:27.280 --> 00:07:32.960
case and cooler you buy whatever you need though you can find it

00:07:30.560 --> 00:07:36.800
at today's sponsor micro center if their online builder tool isn't enough just

00:07:35.039 --> 00:07:40.720
head inside and ask for help from any of their knowledgeable staff members their

00:07:38.560 --> 00:07:43.919
