WEBVTT

00:00:00.160 --> 00:00:08.000
recent recently alex and i shot a video

00:00:04.080 --> 00:00:11.120
assembling what is the very first

00:00:08.000 --> 00:00:14.400
Linus media group manufactured

00:00:11.120 --> 00:00:17.279
CPU water block now of course our

00:00:14.400 --> 00:00:21.520
objective though in all of that was not to build a CPU water block because quite

00:00:19.680 --> 00:00:27.039
frankly we could call up our friends at alphacool ek swift basically anyone and

00:00:25.199 --> 00:00:33.120
they would do a much better job of it than we did no offense yeah not taken

00:00:29.599 --> 00:00:36.640
the objective was for us to water cool a

00:00:33.120 --> 00:00:38.640
red 8k camera but baby steps right so

00:00:36.640 --> 00:00:42.320
this was doing something pretty normal where we could basically clone a chinese

00:00:41.040 --> 00:00:46.320
design and then just put it on the cnc

00:00:44.960 --> 00:00:51.200
today we kick things up a notch with this

00:00:49.280 --> 00:00:57.760
we're gonna water cool something a little unusual our 10 gigabit 12 port

00:00:55.039 --> 00:01:04.000
network switch from netgear that was actually the first 10 gigabit piece of

00:01:01.359 --> 00:01:07.280
equipment that we got well not counting like network cards

00:01:06.400 --> 00:01:10.600
like like a switch

00:01:15.760 --> 00:01:22.960
the hot docs uses the ergodox design which keeps you comfortable typing away

00:01:20.400 --> 00:01:27.759
for long periods of time and features qmk firmware and hot swappable key

00:01:25.200 --> 00:01:30.960
switches check it out at the link below uh so this is it

00:01:29.759 --> 00:01:34.720
um they don't get

00:01:32.799 --> 00:01:38.240
their network switch anymore in the camera then yep just unplug it yep all

00:01:37.439 --> 00:01:42.159
right well oh crap we were supposed to do the sound

00:01:40.560 --> 00:01:46.000
test first that's kind of the whole point if you guys

00:01:44.240 --> 00:01:50.479
it's really loud yeah this is going to be a very inexact

00:01:48.799 --> 00:01:55.520
unscientific test here

00:01:51.920 --> 00:01:58.159
56 decibels sure on boot up okay let's

00:01:55.520 --> 00:01:58.159
water cool it

00:01:58.640 --> 00:02:02.880
how much does steve pay us for all this product placement that he gets on our

00:02:01.840 --> 00:02:06.000
channel like nothing

00:02:05.200 --> 00:02:11.280
so the reason that network switches are

00:02:08.720 --> 00:02:16.879
really loud and run really hot is not necessarily because the hardware inside

00:02:14.080 --> 00:02:21.200
them it has a ton of power draw or anything like that it's because cooling

00:02:18.959 --> 00:02:27.599
them is a real challenge most network switches even at the prosumer level are

00:02:23.920 --> 00:02:29.680
in what's called a single u which is the

00:02:27.599 --> 00:02:33.200
i don't know the universal unit that's where the u comes from

00:02:31.200 --> 00:02:38.640
i'm just kidding i made all of that up for height in a rack so that means you

00:02:36.080 --> 00:02:42.080
can only use these wimpy 40 millimeter fans

00:02:39.599 --> 00:02:46.720
and a lot of the time you also don't have a lot of ventilation holes for

00:02:44.160 --> 00:02:50.080
whatever reason what's funny i actually brought my own

00:02:48.400 --> 00:02:53.599
handle because i was using this for something

00:02:51.680 --> 00:02:57.360
before we started so i can help

00:02:56.000 --> 00:03:03.599
oh man i just stripped that bit

00:03:00.720 --> 00:03:08.480
that took a long time i'm gonna go get a bigger screwdriver

00:03:06.239 --> 00:03:13.040
oh there's the one he stripped oh

00:03:09.599 --> 00:03:13.040
bloody hell i just stripped this one too

00:03:14.080 --> 00:03:20.319
see i just had to go in straight that's what my mom always said what i'm

00:03:18.959 --> 00:03:23.599
actually really looking forward to this i have it's it's a funny thing because

00:03:22.080 --> 00:03:26.720
like computers the first thing i do with them is open them up like laptops and

00:03:25.280 --> 00:03:30.640
stuff but it's never occurred to me to open up

00:03:28.879 --> 00:03:35.840
our 10 gig network switch is this one that's still not oh

00:03:34.080 --> 00:03:40.640
oh there we go so up and back cool holy crap there's a

00:03:38.879 --> 00:03:45.360
lot of stuff to cool in here what is this are they ripping us off huh is

00:03:43.840 --> 00:03:48.879
there another port that they don't put on the front maybe they're just afraid

00:03:46.959 --> 00:03:53.040
of having it be 13. so here's our power supply that we're definitely not going

00:03:50.879 --> 00:03:56.879
to touch or even get close to so my intention had been to keep it 1u

00:03:55.360 --> 00:04:01.680
mountable though oh okay yeah but then just have like

00:03:59.680 --> 00:04:06.640
tubing out like quick connects or something and then like an external rad

00:04:04.319 --> 00:04:11.040
okay i mean that's one option i'm not married to it though for whatever reason

00:04:08.480 --> 00:04:15.120
in my mind i was picturing kind of like this goes on here yeah

00:04:13.120 --> 00:04:19.280
and we just like cut two holes for tubing

00:04:17.040 --> 00:04:23.440
and then mount a rad like right here

00:04:20.560 --> 00:04:27.680
like full like like engine blocks showing through the top of the hood

00:04:25.120 --> 00:04:30.639
muscle car muscle switch and then i guess if you really wanted to we could

00:04:29.040 --> 00:04:35.120
put like some t-connectors in there so you can make it a 1u have it go out the

00:04:32.320 --> 00:04:38.800
side so it looks like every one of these heat sinks

00:04:37.199 --> 00:04:42.639
is hard mounted so there's screws going in from the

00:04:40.960 --> 00:04:45.840
bottom of the pcb and this whole main board needs to come out before we're

00:04:44.000 --> 00:04:49.680
going to be able to remove any of this now to be clear this is not as

00:04:47.600 --> 00:04:53.840
expensive as a red camera but this is still today

00:04:52.000 --> 00:04:57.520
what like an 800 network switch or something like that i have no clue yeah

00:04:56.080 --> 00:05:01.840
let's be careful with it because i can't remember how much it costs either it's not cheap though i always wonder if we

00:05:00.479 --> 00:05:06.400
could just get away with putting little copper things on here sort of like you

00:05:03.600 --> 00:05:10.240
said but then run a heat pipe just straight across all of them if we used a

00:05:08.320 --> 00:05:13.199
ball nose bit that was the right size we could cut a channel

00:05:11.680 --> 00:05:18.080
right in the top of it the right size for the heat pipe yep and then just

00:05:15.440 --> 00:05:20.960
solder it on and and then we managed to spread the heat out that way okay and

00:05:19.759 --> 00:05:25.680
that way we've just got this big spreader that'll carry the heat

00:05:23.360 --> 00:05:28.560
theoretically hopefully towards our cooling yeah

00:05:27.759 --> 00:05:36.800
okay wait a minute what oh those all soldered on there's no way how

00:05:33.440 --> 00:05:36.800
could they possibly be

00:05:37.520 --> 00:05:42.960
that's gonna be a pain in the butt should i go get the soldering iron yeah

00:05:41.840 --> 00:05:48.080
all right what do you think the chances are that they're soldered on and then epoxied

00:05:45.759 --> 00:05:53.280
underneath i was just thinking oh we do have a wig how hard do you

00:05:49.440 --> 00:05:54.479
think it is just snip those

00:05:53.280 --> 00:05:56.800
oh ah

00:06:01.120 --> 00:06:06.840
there easy as pie

00:06:10.240 --> 00:06:14.880
i should have been wearing eye protection for that brandon you're wearing glasses right

00:06:14.080 --> 00:06:20.960
yeah i think we can get in there and just give her like a little snip

00:06:18.639 --> 00:06:27.360
you got to be kidding me oh you you're doing it you actually did it

00:06:23.360 --> 00:06:27.360
you actually did that works so well

00:06:27.440 --> 00:06:33.280
everybody's got eye protection on me everybody's going to be screaming so

00:06:31.360 --> 00:06:36.160
much like they got so mad when i just like hacked off the dvi connector and

00:06:35.120 --> 00:06:40.800
that's like a bunch of pins

00:06:39.039 --> 00:06:44.960
that one hit over there and then landed over there this is that is so dumb what we're doing

00:06:43.919 --> 00:06:50.800
wow yeah not bad so you got a couple challenges

00:06:48.560 --> 00:06:55.280
these look like they're up a little high so we might end up having to kind of go

00:06:52.880 --> 00:06:59.199
around them um also not all these holes came clear so we

00:06:57.280 --> 00:07:03.440
might have to either pop them back out or actually desolder them properly if we

00:07:01.280 --> 00:07:09.599
want mounting points for our block yeah your copper slab to cover it

00:07:06.800 --> 00:07:12.639
is probably the simplest way here's our main CPU block

00:07:11.199 --> 00:07:16.880
and then we do a short heat pipe here and a long

00:07:14.880 --> 00:07:20.240
heat pipe here this is actually going to be pretty difficult

00:07:18.479 --> 00:07:24.960
yeah i don't know why i wasn't thinking it would be difficult

00:07:21.599 --> 00:07:24.960
but it's going to be quite difficult

00:07:28.479 --> 00:07:33.520
can we can we do this where i actually here hold on hold on hold on can can we

00:07:32.080 --> 00:07:36.720
can we pretend that i had something to do with this and i'm like oh god what

00:07:35.199 --> 00:07:40.400
did you do okay you can do it so

00:07:38.479 --> 00:07:48.479
how did you do that over the last week or so he created this fantastic

00:07:45.440 --> 00:07:50.400
well i mean what would you call this

00:07:48.479 --> 00:07:53.039
model yeah it's just like a little model so we have the switch here all the

00:07:51.599 --> 00:07:56.160
critical measurements for our water cooling is in there and you ended up

00:07:54.720 --> 00:08:03.039
buying new calipers for that is that right uh yeah is it the big daddy

00:07:59.039 --> 00:08:03.039
caliper no it's the alex's calipers

00:08:03.120 --> 00:08:09.120
and these are really fancy because they're just very repeatable and

00:08:07.280 --> 00:08:12.879
expensive we had problems in the past where i

00:08:11.199 --> 00:08:16.560
would measure a bunch of things and error would stack up so i guess there

00:08:14.639 --> 00:08:19.039
were a couple problems that we had to solve here

00:08:17.680 --> 00:08:22.720
so the first is that i was pretty concerned that having this many heat

00:08:20.800 --> 00:08:25.599
sources on one heat pipe would cause problems

00:08:24.000 --> 00:08:30.080
so we have this paper here that sort of solved this for us which is an investigation of thermal characteristics

00:08:28.639 --> 00:08:33.919
on a centered wick heat pipe with double heat sources basically tells us you want

00:08:32.080 --> 00:08:38.640
your heat sources to be as close to the condenser as possible

00:08:35.519 --> 00:08:40.800
so our condenser is effectively this

00:08:38.640 --> 00:08:45.120
segment of the heat pipe right here where it will be thermal epoxy to this

00:08:43.360 --> 00:08:49.680
copper plate which is going to be water cooled and then i guess other things

00:08:47.440 --> 00:08:54.080
jonathan from ascend ceiling contacted us uh

00:08:50.800 --> 00:08:55.120
and we have a heck ton of o-rings like

00:08:54.080 --> 00:09:00.080
he's just he's just been raining o-rings on us

00:08:57.920 --> 00:09:04.480
so so we have better o-rings this time yeah and also his card stock is amazing

00:09:02.240 --> 00:09:10.000
like look at this it's quality yeah can we get some of this no and yeah we have

00:09:06.959 --> 00:09:11.680
new o-ring lube so basically

00:09:10.000 --> 00:09:16.320
nothing can go wrong yeah well things can go wrong but that's what we're about

00:09:13.600 --> 00:09:19.200
to get to the hard part though is that we have to actually machine this

00:09:18.240 --> 00:09:23.920
so how do you machine a rounded groove

00:09:21.760 --> 00:09:26.959
so we have a ball-nosed end mill so that's just like it's round on the

00:09:25.200 --> 00:09:30.880
end and you just kind of kind of just like that which was this

00:09:28.720 --> 00:09:35.279
was like surprisingly hard to get to work properly

00:09:32.240 --> 00:09:36.560
so big shout out to cj from autodesk he

00:09:35.279 --> 00:09:42.000
really it's going to be like half a sketchy one

00:09:39.200 --> 00:09:46.320
because we can't go any lower than 78 000 RPM

00:09:43.440 --> 00:09:49.680
on our cnc router so really we should be using a mil for this we should be using

00:09:48.160 --> 00:09:53.920
a mil for this but we don't have a mill because they're expensive yes when

00:09:52.000 --> 00:09:56.480
you're going to cut metal you need to make sure that every single time that

00:09:55.200 --> 00:10:00.160
the tooth comes around you're actually like cutting out a chunk of metal or

00:09:58.399 --> 00:10:04.480
it's just going to rub and it's going to burn it out really fast so since we

00:10:02.160 --> 00:10:08.240
can't make the tool spin slower we need to run it faster

00:10:06.160 --> 00:10:11.920
we're being safe right yep i don't want people yelling at us about our cnc

00:10:10.640 --> 00:10:16.959
yeah do you want to plug in the air compressor yeah i'd love to we do have

00:10:14.240 --> 00:10:20.720
actual mist cooling now so everyone that's saying you should have cooling we

00:10:19.040 --> 00:10:24.079
already have to blanket well you can definitely see the shmoo

00:10:22.720 --> 00:10:30.959
here so is this just getting like more and more legit every time we do a video yeah

00:10:27.760 --> 00:10:32.640
basically this is leaking

00:10:30.959 --> 00:10:37.680
yeah it got dropped so we're ready yep can i press go

00:10:35.440 --> 00:10:37.680
uh

00:10:38.959 --> 00:10:46.519
i like to feel like i'm helping and that's the tool that we have so yeah

00:10:47.839 --> 00:10:51.839
that is not that clean looking no

00:10:56.000 --> 00:11:02.399
no and we're done so what happened there

00:11:00.480 --> 00:11:07.120
was the piece of copper that we're trying to cut

00:11:03.839 --> 00:11:09.519
shifted which means that

00:11:07.120 --> 00:11:14.720
the entire tool path that alex laid out is now offset by

00:11:11.680 --> 00:11:16.720
about three quarters of a centimeter so

00:11:14.720 --> 00:11:19.360
it's possible that we would have ended up with

00:11:17.839 --> 00:11:24.320
something usable but our thermal transfer is not going to be great

00:11:22.320 --> 00:11:28.240
i mean if it had held down we would have something here anyway

00:11:26.640 --> 00:11:33.680
i could that's really bad for the tool and we

00:11:30.640 --> 00:11:33.680
have to make four of them

00:11:36.000 --> 00:11:40.240
and we're back this time with a bit of a new plan

00:11:39.360 --> 00:11:47.200
so now we have bolted

00:11:42.480 --> 00:11:47.200
our copper plate down to the bed

00:11:47.680 --> 00:11:53.200
we have also made some canadian engineering repairs to our reservoir

00:11:51.200 --> 00:11:58.720
down here it no longer leaks thanks to some hand mix epoxy and uh we have done

00:11:56.240 --> 00:12:04.240
away with our plan to make rounded grooves because we don't have a mill we

00:12:01.839 --> 00:12:07.200
only have a router so why don't we just let the work speak for itself instead of

00:12:06.079 --> 00:12:12.880
telling them what's gonna happen i can press go now right um

00:12:11.360 --> 00:12:25.720
hey hey

00:12:26.560 --> 00:12:32.000
let's see the finished product so this is going to be the top of one of our

00:12:31.040 --> 00:12:37.200
blocks this is going to be the top of one of our other more different blocks

00:12:35.440 --> 00:12:41.920
this is the block we made last time which is still here again for some reason we're using the bottom of it oh

00:12:40.000 --> 00:12:45.600
we're just reusing it yeah i mean why dull your bits when you don't have to oh

00:12:43.839 --> 00:12:49.920
is this it yeah so this is

00:12:46.959 --> 00:12:55.839
the moment of truth right now oh perfect it really is actually

00:12:52.560 --> 00:12:57.440
yeah it's 0.1 of a millimeter oversized

00:12:55.839 --> 00:13:00.959
good work i'm happy with that

00:12:59.200 --> 00:13:04.160
um i guess we just need to clean these off and

00:13:03.120 --> 00:13:11.279
tap them look at that it just looks so good underneath completely see-through we

00:13:07.760 --> 00:13:13.040
didn't bother facing it this time

00:13:11.279 --> 00:13:16.480
that should go there yeah that goes right and then we'll have the three that

00:13:15.040 --> 00:13:18.800
go down the middle here

00:13:18.839 --> 00:13:24.079
whoa that's a lot of copper

00:13:22.079 --> 00:13:27.839
now you told me pro mode was gonna have the heat pipe on the bottom so that we

00:13:25.839 --> 00:13:32.320
were like heat pipe direct touch cooling yeah are we doing that with this one no not

00:13:30.959 --> 00:13:36.320
with this one no that's gonna be version two what do you

00:13:34.240 --> 00:13:41.839
mean version two we need to get this done because ed's mad they don't have

00:13:38.720 --> 00:13:42.880
a switch for their ingest crap

00:13:41.839 --> 00:13:47.680
but just crap yeah ingest crap we don't we

00:13:45.600 --> 00:13:53.120
don't need these videos but yeah we're going to have to redesign

00:13:49.600 --> 00:13:55.440
this guy and alphacool is coming up with

00:13:53.120 --> 00:13:58.720
those like the server-sized heatsinks so those are going to like go

00:13:57.199 --> 00:14:02.399
in the side and it's going to look super legit but until then we're just going to

00:14:00.320 --> 00:14:08.399
like have it Linus tech 2 style just like below the ingest station

00:14:05.360 --> 00:14:08.399
do these screws go through

00:14:08.560 --> 00:14:15.600
not quite we don't have to widen the holes in the

00:14:12.720 --> 00:14:18.480
pcb do we are you kidding me

00:14:18.959 --> 00:14:25.120
well it's potentially going to be the quietest and coolest switch on

00:14:22.959 --> 00:14:30.279
like everywhere arguably a switch that doesn't power on anymore is very quiet

00:14:26.959 --> 00:14:30.279
and very cool

00:14:32.639 --> 00:14:38.720
ah this bit might actually be too small that went super well nope we're good

00:14:36.639 --> 00:14:43.480
what that was it yep that's that's all we needed oh

00:14:40.480 --> 00:14:43.480
nice

00:14:50.800 --> 00:14:57.560
we should probably give this a little dusty here yeah

00:14:54.560 --> 00:14:57.560
something

00:14:58.880 --> 00:15:04.800
yeah this is pretty bad yeah it was definitely one of the worser

00:15:02.959 --> 00:15:08.000
ideas i've ever seen like am i just going at it with this i like

00:15:06.320 --> 00:15:12.399
legitimately straight up forget how to do it um what about this time we just

00:15:10.000 --> 00:15:16.800
like clamp it like this yeah off the table yeah

00:15:15.120 --> 00:15:21.120
you can just kind of get this on the side like like so and blame obama okay

00:15:20.079 --> 00:15:27.440
there are a lot of people that were really mad last time that we didn't use the drill press to do this so it would

00:15:24.399 --> 00:15:28.959
go down perfectly straight oh yeah that

00:15:27.440 --> 00:15:33.920
would be smart wouldn't it yeah it really would you guys want to do that

00:15:31.199 --> 00:15:33.920
nope nope

00:15:36.079 --> 00:15:42.160
wait what the crap is this crap is what this hole

00:15:40.880 --> 00:15:45.680
doesn't go all the way straight through the drill press had an issue

00:15:44.079 --> 00:15:49.040
yeah it's good okay this is the really bad one i don't know

00:15:47.279 --> 00:15:52.279
about that well you'll be able to tell from the bottom

00:15:54.000 --> 00:16:02.000
oh jeez what did you just do that is that's pure carnage right there

00:15:59.199 --> 00:16:02.000
oh god

00:16:04.560 --> 00:16:09.000
that's a lot of acrylic on the floor

00:16:11.440 --> 00:16:16.800
yeah uh these don't quite line up well like

00:16:14.720 --> 00:16:21.759
do you want to tap those holes again oh they're all the way over here

00:16:19.040 --> 00:16:26.639
oh crap okay so we're just kind of doing the

00:16:23.360 --> 00:16:26.639
same thing as last time then yep

00:16:27.680 --> 00:16:37.240
acrylate me extra cyano on the side

00:16:32.959 --> 00:16:37.240
and theoretically it will seal

00:16:39.759 --> 00:16:45.440
we're asking for a lot of tight tolerances to

00:16:43.279 --> 00:16:48.079
line up here yep we're gonna put

00:16:46.800 --> 00:16:51.680
that through a plastic washer

00:16:50.800 --> 00:16:56.720
okay so that goes there then we do another plastic washer i'm

00:16:54.880 --> 00:16:59.279
assuming um yeah

00:16:58.320 --> 00:17:04.240
okay can we do a nut yup not me

00:17:02.160 --> 00:17:07.039
there so i've realized something really

00:17:05.600 --> 00:17:10.559
unfortunate where this right here screws in i

00:17:09.120 --> 00:17:15.039
thought that it was just like nuts on the back that came up

00:17:12.240 --> 00:17:19.199
yeah but it's actually screwed right into the chassis

00:17:16.640 --> 00:17:21.520
yeah i don't know if these can come off oh

00:17:23.120 --> 00:17:30.320
i can't believe that you got all these holes to mostly sort of line up

00:17:28.160 --> 00:17:34.880
i measured it are you guys as excited as we are to see

00:17:32.320 --> 00:17:37.200
if this thing is still gonna work i am

00:17:37.200 --> 00:17:42.320
i'm amped assuming that we didn't kill it

00:17:40.960 --> 00:17:46.480
it's gonna work pretty well i mean we didn't do anything that bad to it

00:17:45.600 --> 00:17:50.320
not really we're not gonna actually power on the

00:17:49.440 --> 00:17:56.400
switch we're just gonna power this pump and then make sure that nothing leaks

00:17:54.240 --> 00:18:00.880
did you fart yeah but like a couple minutes ago

00:17:58.559 --> 00:18:04.799
it's really lingering oh well i'm sorry about that

00:18:03.280 --> 00:18:10.480
it's awkward all right well given that our system here has

00:18:08.000 --> 00:18:15.679
passed our exhaustive three-minute uh stress test

00:18:12.880 --> 00:18:20.000
would you say we're ready to power it on yeah

00:18:17.600 --> 00:18:26.720
there's a light david oh it's green identifying it's green

00:18:22.720 --> 00:18:29.919
that means 10 gig link oh yeah test

00:18:26.720 --> 00:18:31.440
and there it goes indeed

00:18:29.919 --> 00:18:35.840
boom okay so now what no now we we actually

00:18:33.760 --> 00:18:38.799
get to put it together yeah i guess so okay

00:18:37.760 --> 00:18:45.200
damn i have screen cap going so you don't need to come over here

00:18:43.520 --> 00:18:49.600
there is one more test though it's possible that we're not making good

00:18:47.120 --> 00:18:52.400
contact with uh anything like we actually don't know that just because

00:18:50.799 --> 00:18:55.919
it's working that means it's working well i love that our fans just say

00:18:54.240 --> 00:19:02.240
failure because they're not they're not plugged in question for you though yeah uh did you

00:18:59.520 --> 00:19:06.160
get new like quieter 40 millimeter fans to replace these well i guess if it's

00:19:04.000 --> 00:19:10.799
just open can we just stick like a 140 on top or something

00:19:09.520 --> 00:19:15.120
yes yes we can all right

00:19:13.280 --> 00:19:19.039
yeah so what we can do is we can take this puppy

00:19:17.520 --> 00:19:23.600
put it on do a 140 millimeter cutout

00:19:21.440 --> 00:19:27.600
mount the radiator to that so that nothing could slip through put

00:19:25.360 --> 00:19:30.480
the fan on top and put a fan grill on disassemble this

00:19:29.120 --> 00:19:34.640
and put it in and i'll get a hole in here sure cool are you gonna measure

00:19:32.400 --> 00:19:38.799
where the hole goes yep so i think we're almost done here

00:19:37.200 --> 00:19:42.799
um okay

00:19:40.559 --> 00:19:45.919
speak for yourself because we need to power the pump

00:19:44.960 --> 00:19:51.960
oh i think what we have to do is plug in

00:19:48.400 --> 00:19:56.720
the power supply and start probing

00:19:56.720 --> 00:20:01.760
it's in panic mode and i put it in the ammeter oh

00:20:00.640 --> 00:20:08.240
all right well let's see if anything still works

00:20:09.120 --> 00:20:18.559
12 volts yay wow it's a christmas friggin miracle okay

00:20:16.160 --> 00:20:23.919
so that is

00:20:21.039 --> 00:20:29.840
ground and 12 volt look here

00:20:25.919 --> 00:20:31.760
so ground is the far left 12 volt is the

00:20:29.840 --> 00:20:36.320
third theoretically orange is ground what

00:20:35.200 --> 00:20:41.360
the black is positive 12 volt and yes Jake

00:20:39.840 --> 00:20:45.280
it matters okay i have good news though

00:20:44.559 --> 00:20:52.000
look what i found what in the bowls is that this is a six

00:20:49.360 --> 00:20:57.120
pin pci express adapter see these two pins it's a six to eight pin adapter we

00:20:54.320 --> 00:21:02.400
can use these two wires to find our 12 volt power and then splice that onto the

00:21:00.080 --> 00:21:06.320
power connector for the pump so then as long as we get the right two

00:21:03.919 --> 00:21:10.720
pins then we're good okay so what did i say orange was ground

00:21:08.000 --> 00:21:14.640
black was 12 volt yup neat theoretically

00:21:12.720 --> 00:21:18.240
when i plug in the switch it will turn on with no sparks

00:21:23.440 --> 00:21:26.400
power leds lit

00:21:27.520 --> 00:21:32.880
and theoretically okay more sanity check

00:21:31.280 --> 00:21:37.840
time i have 12 volts here

00:21:35.600 --> 00:21:41.200
oh huzzah

00:21:39.679 --> 00:21:47.760
what a nightmare yeah now it just needs to get connected to this yeah

00:21:44.960 --> 00:21:51.440
other than the hole in beginning this is actually surprisingly like sort

00:21:50.159 --> 00:21:55.679
of properly done yeah like sort of properly

00:21:54.400 --> 00:22:01.280
i mean there's no proper way to do something that's stupid yeah like i guess if we could get a

00:21:58.480 --> 00:22:05.360
couple zip ties in there like yeah 100 pro

00:22:03.919 --> 00:22:12.080
all right a couple LTT cable ties get that

00:22:08.720 --> 00:22:15.039
shilling in there oh yeah um a bit

00:22:12.080 --> 00:22:19.120
concerned about putting this on how come we have to kind of go over the tubes

00:22:17.840 --> 00:22:22.240
and just not slice them

00:22:20.880 --> 00:22:27.480
well but can you get your hand in there when it's like that uh yeah i have small

00:22:24.480 --> 00:22:27.480
hands

00:22:27.679 --> 00:22:32.400
here if you let go here i can help you align this side

00:22:31.039 --> 00:22:36.890
we might as well well have these ones kind of come up similarly you know

00:22:35.200 --> 00:22:41.250
okay

00:22:43.360 --> 00:22:49.360
the best part is that like it looks so good on the inside like it's pretty like

00:22:48.080 --> 00:22:56.480
pro like all machine and stuff and on the outside it's just like straight like ghetto like

00:22:54.320 --> 00:23:00.960
not even the same color tubes hot rodded like

00:22:58.080 --> 00:23:05.280
it's not very space efficient it's very

00:23:01.919 --> 00:23:06.400
heat efficient yeah does it work faster

00:23:05.280 --> 00:23:12.640
no it's a lot quieter yeah did you see how quiet it is i don't

00:23:10.640 --> 00:23:16.960
think i ever actually heard it so that didn't seem like an issue to me but uh

00:23:15.360 --> 00:23:20.799
it was like yeah it was pretty loud

00:23:18.720 --> 00:23:25.440
it's still working temperatures are actually lower but we have a fan running

00:23:23.280 --> 00:23:29.360
on the radiator now so that's an improvement yeah we're looking at 27 and

00:23:27.600 --> 00:23:34.400
28 degrees compared to like 51 and 42 before it's

00:23:32.400 --> 00:23:40.400
dead silent and let's do a quick file transfer here

00:23:37.679 --> 00:23:40.400
here we go

00:23:40.720 --> 00:23:43.360
