welcome back to the workshop last time we were here testing something I believe
0:03
it was how many case fans do you need and in what position today we're going
0:07
to be doing another cooling investigation video this one is going to
0:10
be based on cable management so we're going to look into uh how much it
0:14
actually affects your cooling now there's a little bit of a problem here
0:19
which is where most cases these days are actually pretty damn good and have a lot
0:23
of space behind the motherboard and have like very clear ways that you're
0:26
supposed to Route the cables which isn't in places that would affect the cooler
0:31
so you're probably fine but this is more
0:34
of an investigation as a whole sometimes you'll see comments online where someone
0:37
will be like your cooling's going to be terrible cuz you left a few cables going
0:42
in front of those fans so we're going to check that out I don't know the answer
0:46
yet let's test everything
0:57
live Intel brings ddr4 to the main stream with their new core i76700 K and
1:02
core i56600k processors check out the
1:05
link in the video description to learn more okay so test one is going to be uh
1:11
well pretty good in terms of cable management like this should be our
1:14
Benchmark for clean Cable Management it's not the best that has ever been
1:19
done but it's at the point where I think it's not going to affect the cooling in
1:23
any way so this is pretty bare in terms of setup for cooling we have a hyper 212
1:27
Evo finally I'm not putting it in a T4 and pretending it's a 212 Evo thank you
1:32
atmt grimes5 on Twitter for sending this
1:35
to me by the way emailed that to me directly cuz he was tired of me
1:39
complaining about not having one so there's one fan on there there's one 140
1:43
mm fan in the front there's a 140 mm fan
1:46
in the back and there's two 120 mm fans
1:50
in the top so this will be our base
1:53
Benchmark for how this computer is able
1:56
to perform with pretty good Cable Management we we will then record its
2:01
numbers and then I'll start messing with the cables more and making it Messier
2:04
and Messier and just see how far the rabbit hole goes so I've got the case
2:08
all closed up and now I'm doing some testing so this is going to be run for
2:12
about 10 minutes total I'm running furmark on the GPU and recording
2:16
temperatures of the GPU using MSI After Burner and then I'm doing a system
2:20
stability test with ID to 64 in order to push the CPU so this should heat
2:25
everything up and get us to a relatively hopefully High number
2:30
um although this isn't a particularly hot graphics card and the hyper 212 Evo
2:36
is probably going to do fine because nothing's actually overclocked and then
2:41
uh we'll start throwing more cables in there and messing around okay so results
2:45
of the first tests are in again this is more just a benchmark for the rest of
2:50
the benchmarks this is where like okay there's no real cable obstructions going
2:54
on so our CPU is at about 50° and our
2:58
GPU is at about
3:02
82° so we're going to document that make the cables a little bit worse and move
3:06
on okay so I've added some cables I haven't added an insane amount of cables
3:10
I have three big thick ones going across
3:13
the front I have one going kind of through the middle and then I have one
3:18
placed as a pseudo not very well-managed eight pin going like across over the
3:23
power supply by the back of the CPU Cooler and then up to where the eight
3:27
pin placement would be I don't expect this is going to fect much but I haven't
3:31
tried it yet so let's figure it out okay so this one's good to go well okay let's
3:36
be clear if you're building your own system don't leave your cable management
3:40
that crappy but it's good to go for this test for what I need it to do right now
3:45
so walking over to this screen I'm now
3:48
going to set the test back up so yet again fur Mark for the GPU stress test
3:54
and then starting Ida 64 for the CPU
3:58
another 10 minutes we'll record the numbers and see how it did see if it
4:02
actually affected anything I'm kind of thinking it won't or at least not very
4:07
much so that did absolutely nothing 50° on the CPU still
4:14
82° on the GPU we're going to have to make this Cable Management a lot worse
4:19
that's going to be the next step I'm going to add like maybe most of
4:25
this and we'll see what happens side
4:28
panel's on fur Mark is set up Ida 64 is
4:31
already running this test is a go I know I've said this a few times already but
4:36
if this doesn't produce a result there's probably not a ton that I can even do to
4:40
be completely honest and one of the results from this video might be if you
4:43
have a standard kind of Tower and cable management probably isn't that important
4:47
if you have something like a no 202 or you have that bomb that I built for the
4:50
Fallout build check that video up here then it probably matters because if
4:54
you're completely blocking off all of the air inputs that'll be an issue but
4:57
on a big case like this there's enough just open areas that the air is probably
5:02
going to flow um but who knows we'll see soon
5:08
10-minute test okay so no change at all CPUs at 50
5:14
graphics cards at 82 so yeah seems like if you have a mid
5:20
Tower you're probably fine in terms of K management so we're just going to have
5:23
some fun I'm going to put a Snoopy in there a twitch t-shirt a roll of tape an
5:28
iron a Santa hat and maybe that'll do
5:34
something
5:39
God oops I don't know where I'm going to put
5:43
all this
5:47
stuff now if your cable management is so
5:50
bad that you put a Snoopy of Santa hat and iron and a twitch t-shirt in your
5:56
case we'll see how much that'll affect your airf flow system stability oh I
6:02
forgot the tape it's okay while the tests are running I'm going to add the
6:07
last part that I forgot to add which was
6:10
the roll of tape I'm sure lonus is totally okay with all the things I'm
6:14
doing right
6:17
now nice um I don't know where I can put
6:27
it that's probably fine
6:31
that's okay that's probably okay now
6:35
we're rocking roller tape Snoopy iron
6:38
Santa hat twitch t-shirt let's do this
6:42
tests are currently running let's see how they're going the CPU is currently
6:47
at 50° and the GPU is currently at
6:54
74 what the hell what
7:01
okay okay so it's actually doing fine
7:05
right now which is really
7:09
concerning uh I guess we're going to
7:12
leave it for 10 minutes and then we'll be back 50° on the
7:16
CPU 82° on the GPU I put a shirt a Santa hat a Snoopy
7:22
an iron and a giant roll of tape along with every single cable that came with a
7:26
1200i into a case and it didn't affect anything
7:30
thing next up is boxes I'm going to take all this stuff out maybe put some of it
7:35
back in but use a lot of solid boxes to try to completely block off airflow
7:42
Pathways I want some numbers to go
7:47
up okay so we used the box for the CPU
7:52
Cooler and we used boxes for a bunch of
7:55
water coolers there's one under here or water blocks there's one under here
7:59
there's one to support that and keep it where it is there's one blocking the top
8:03
fans there's one blocking the black back fans so basically every single fan has a
8:07
box currently trying to stop it from being able to work properly except for I
8:12
guess this one there now there's a Santa
8:16
hat screwing with that one now that we've done all this I'm going to put the
8:21
case panel back wait hold up hold up
8:24
hold up can move that out of the way all right I'm going to put the case panel
8:28
back on I'm going to close this up I'm already
8:33
running the tests I didn't even stop them because nothing's changed this
8:36
whole freaking time so we're currently running furmark and currently running
8:41
Ida 64 I'm going to come over here and see if there's been any immediate
8:48
changes the GPU has not increased in temperature despite having a shirt
8:52
shoved into it and a box under it but it looks like we have a slight in
8:59
increase in CPU temperatures oh good we'll check back in
9:05
10 minutes we did it by adding four boxes
9:09
for water blocks one box for hyper 212
9:13
Evo a T-shirt and a Santa hat
9:16
effectively putting crap directly in front of every single fan there is we
9:21
have gotten the CPU to about
9:24
77° and we've gotten the GPU to 86°
9:30
done so yes in the end it took four
9:34
boxes for water blocks it took one box for a CP cooler it took a t-shirt a
9:39
Santa hat and all of these
9:42
cables in addition to the cables that were already inside which totals a pile
9:48
that looks something like this placed
9:51
into the computer in addition to the required components to heat it up so
9:56
your bad cable management in your mid Tower is probably fine this didn't
9:59
include tests for things like really really small cases or very specific
10:04
builds like the bomb we have or something like a node 202 or like an
10:08
rvz01 from Silverstone but yeah it's probably fine if your C
10:13
management is bad but like I don't know how to word this because don't just use
10:19
that as an excuse to have bad kill management we don't want ugly computers
10:23
it's not a good idea don't post a build log on the Forum and go like lol Luke
10:27
told me it was okay to have terrible Cable Management because it's not going
10:30
to increase my thermals very
10:33
much just do it properly everything will be fine apacer is giving away five
10:39
apacer as 330 Panther 240 GB ssds for a
10:45
chance to win check out the link in the video description Down Below on the lineus tech tips Forum also they' like
10:50
me to call it their nox ddr4 sodm memory design for gaming Enthusiast Graphics
10:55
designers and business users they're energy efficient consuming 1.2 volts and
10:59
it can go up to 64 GB in their total kit
11:03
capacity also they want me to call it the as720 SSD it's dual interface so you
11:08
use it internally or externally it's at 120 GB or 240 GB that's USB type c or
11:14
SATA internally if you want to do it that way thanks for watching this video
11:19
it didn't really come out as I expected and I don't think the conclusion or what
11:23
I had to do to get to the conclusion was necessarily what anyone expected but I
11:27
hope you like watching consider supporting like the video if you liked it dislike if
11:31
you disliked it um get subscribed
11:36
consider supporting us through Amazon he's an affiliate code buy an awesome
11:39
t-shirt or uh sweater wherever I ended
11:43
up putting that and yeah we have other
11:47
videos if you want to see the previous video which was how many case fans do you need click that it's up there and
11:52
I'll see you next time
