WEBVTT

00:00:00.719 --> 00:00:07.040
this right here is the phenomic hex 2.0

00:00:05.200 --> 00:00:11.519
CPU cooler and if you were to look at the

00:00:09.120 --> 00:00:16.240
performance claims alone you'd be forgiven for thinking there's some kind

00:00:13.440 --> 00:00:20.320
of magic going on here since it seems to be able to cool

00:00:18.000 --> 00:00:24.000
much better than its relatively small size would suggest

00:00:23.039 --> 00:00:31.519
but unfortunately for perpetual motion machine makers and this cooler alike

00:00:28.400 --> 00:00:33.520
magic is not real

00:00:31.519 --> 00:00:38.079
and thermodynamics is what makes this product special is of

00:00:35.520 --> 00:00:43.760
course its use of a peltier or thermoelectric cooler which uses

00:00:40.000 --> 00:00:46.160
electricity to move heat from one side

00:00:43.760 --> 00:00:49.440
of the device down here or up there wherever it is to the other

00:00:48.559 --> 00:00:54.079
pretty cool but what's even cooler

00:00:52.640 --> 00:00:59.199
is this what alex is holding is two aquarium

00:00:56.399 --> 00:01:05.199
coolers using a similar technology which together should be able to provide

00:01:01.640 --> 00:01:07.119
360 watts of cooling power so we're

00:01:05.199 --> 00:01:11.600
going to see how our two contraptions here manage against a 10 core

00:01:09.280 --> 00:01:15.520
overclocked processor in a new crazy cooling experiment series that we're

00:01:13.360 --> 00:01:20.040
calling bad cooling ideas

00:01:17.840 --> 00:01:24.040
yeah

00:01:25.040 --> 00:01:31.680
vincero watches is celebrating their five-year anniversary and everything on

00:01:29.040 --> 00:01:36.180
the website is on sale until august 18 2019. check them out at the link in the

00:01:33.840 --> 00:01:44.479
video description

00:01:44.479 --> 00:01:51.360
all right so tech cooling is pretty well established at this point but that

00:01:48.799 --> 00:01:56.079
doesn't prevent people from marketing it as basically magic check out this

00:01:53.759 --> 00:01:59.439
desktop cooler on kickstarter so

00:01:56.960 --> 00:02:04.560
the way apelche or tech works fundamentally is by having electrons in

00:02:02.159 --> 00:02:09.440
the form of dc current pass through two elements in one of the elements the

00:02:06.640 --> 00:02:14.480
electrons go from a low to a high energy state absorbing heat and in the other

00:02:12.239 --> 00:02:19.360
they go from a high to a low energy state releasing heat so you've got the

00:02:16.959 --> 00:02:24.560
cold side and the hot side with a maximum temperature difference of

00:02:21.360 --> 00:02:26.480
usually around 70 degrees celsius the

00:02:24.560 --> 00:02:32.480
cooling capabilities of a tech are directly proportional to the power

00:02:28.800 --> 00:02:34.560
consumption of the tech module so back

00:02:32.480 --> 00:02:39.040
to that kickstarter thing it's not magic at all and really annoyed me when i

00:02:36.400 --> 00:02:45.519
found it in my email so basically all it's doing is using the tech cooler to

00:02:42.560 --> 00:02:51.120
make the water in the back of it hotter so in the end instead of your room being

00:02:48.480 --> 00:02:54.400
cooler which like it does a bit you just end up with a container full of hot

00:02:53.440 --> 00:02:59.599
water it's branded as eco-friendly but it's

00:02:57.200 --> 00:03:05.720
using a tech cooler which are just not efficient at all so it's using heck tons

00:03:02.560 --> 00:03:09.440
of electricity and it costs

00:03:05.720 --> 00:03:10.720
350 dollars and it can only cool 60

00:03:09.440 --> 00:03:16.000
watts a similarly priced refrigerant based

00:03:12.879 --> 00:03:17.200
cooler has literally 50 times more

00:03:16.000 --> 00:03:20.400
cooling but it does have a bluetooth speaker

00:03:19.040 --> 00:03:24.319
which i don't think that's enough to save that my air conditioner doesn't have that

00:03:22.879 --> 00:03:27.840
so let's get this thing on the CPU wait a

00:03:26.879 --> 00:03:32.799
second they did what we tell everyone to do

00:03:30.159 --> 00:03:36.319
they just completely ripped off Noctua's mounting mechanism

00:03:34.480 --> 00:03:42.080
it's completely identical oh yeah yeah i saw that uh it's not

00:03:39.200 --> 00:03:44.959
quite identical it's like a bit worse yeah the back plate is like an

00:03:43.440 --> 00:03:49.760
all-in-one instead of having separate ones for AMD and Intel

00:03:46.959 --> 00:03:52.640
but yeah it's pretty solid yeah good for them

00:03:50.879 --> 00:03:59.360
at least they got one thing right so now that we know tech cooling is not in

00:03:56.239 --> 00:04:03.040
fact magic let's investigate this cooler

00:03:59.360 --> 00:04:05.200
a little bit more closely so phononic is

00:04:03.040 --> 00:04:11.040
not actually the first to attempt to build a peltier into a CPU heatsink

00:04:08.000 --> 00:04:14.720
monsoon coolant and swift tech all did

00:04:11.040 --> 00:04:16.639
it way back in 2007. and there may even

00:04:14.720 --> 00:04:22.800
be earlier instances why didn't it catch on i don't know

00:04:18.959 --> 00:04:25.360
maybe it just wasn't mature enough so uh

00:04:22.800 --> 00:04:31.199
let's take a closer look at this more recent attempt here

00:04:28.720 --> 00:04:35.040
how does this go in it just sits there uh yeah you need to put the

00:04:33.759 --> 00:04:38.400
like that or it doesn't really go back together no that's stupid

00:04:37.520 --> 00:04:46.320
all right and then this goes here and just kind of

00:04:43.919 --> 00:04:48.960
really let's squeeze this together i spent a fair bit of time figuring out

00:04:47.840 --> 00:04:53.600
how to get it back together while you were gone

00:04:50.880 --> 00:04:53.600
yeah hey

00:04:55.360 --> 00:05:01.680
does that screw it all the way down yeah does that mean is that mounting pressure so right oh

00:04:59.759 --> 00:05:06.560
you put it on upside down now the good news is that our uh

00:05:04.240 --> 00:05:11.039
contact looks great between the heatsink and CPU oh yeah so you've got

00:05:08.400 --> 00:05:16.080
pre-testing done on an nhu 12 va right yep now to be clear this is a much

00:05:13.840 --> 00:05:19.440
larger heat sink with almost twice as many heat pipes

00:05:18.560 --> 00:05:23.199
but it's 50 bucks cheaper so

00:05:21.680 --> 00:05:28.080
these things got to find a way to be competitive yeah

00:05:26.160 --> 00:05:32.720
you've got a second power supply just for our heatsink here

00:05:30.320 --> 00:05:37.120
yeah so if you were installing this in a regular computer you would do this

00:05:35.280 --> 00:05:40.479
we are just using a second power supply so we can find out just how much power

00:05:38.880 --> 00:05:44.560
this thing is drawing because of course for a tech to work you

00:05:42.639 --> 00:05:49.120
do need a power source for the palchie module itself which in the case of this

00:05:46.800 --> 00:05:54.080
cooler is embedded in the base between the heatsink fins and heat pipes up here

00:05:51.120 --> 00:05:57.039
and then another piece of copper now theoretically the bottom of this thing

00:05:55.600 --> 00:06:01.199
should be quite chilly it's hard to feel it though i don't know

00:05:59.680 --> 00:06:05.520
right now it's only drawing four watts so

00:06:02.960 --> 00:06:09.840
it might need some input from the fan header to really turn on

00:06:07.759 --> 00:06:14.560
interesting i'm having fun are you guys having fun

00:06:12.560 --> 00:06:18.160
this is probably the coolest thing hey

00:06:16.560 --> 00:06:22.160
i love that merch product placement was that you or david

00:06:20.639 --> 00:06:25.680
i don't know is that just andy's water bottle oh it could be

00:06:25.759 --> 00:06:29.440
uh yeah andy just left his water bottle

00:06:29.759 --> 00:06:34.360
we all have the same water bottle so like

00:06:35.280 --> 00:06:41.440
so we're just doing the good old blender bmw seeing what the max

00:06:39.440 --> 00:06:47.039
temperature is at the end of it we're idling at around 30 low

00:06:45.680 --> 00:06:51.520
30 maybe yeah cool 30 low to 30 min so what we're

00:06:49.759 --> 00:06:58.720
trying to beat is a maximum core temperature of 68 degrees and an overall

00:06:54.400 --> 00:07:00.400
average across all 10 cores of 64.9

00:06:58.720 --> 00:07:06.800
okay you think we're gonna think we're gonna do it no

00:07:02.960 --> 00:07:06.800
oh oh wrong window active

00:07:06.880 --> 00:07:09.440
here we go

00:07:10.240 --> 00:07:14.479
how's our power driver over there three watts right now

00:07:13.440 --> 00:07:19.120
14. 30 oh so it kicked in

00:07:19.199 --> 00:07:24.960
interesting so that's fairly sophisticated it keeps the

00:07:22.880 --> 00:07:29.599
tech idle unless there's an actual heat load which

00:07:27.440 --> 00:07:33.039
is really good because otherwise you would actually end up with your CPU

00:07:31.120 --> 00:07:38.800
reaching sub-ambient temperatures which could cause condensation and shorting

00:07:37.280 --> 00:07:42.160
yeah up to 40 watts 42 is the highest that i've

00:07:40.880 --> 00:07:46.000
seen one of my cores is at 65 already

00:07:45.199 --> 00:07:49.919
okay that's not too bad though okay we're

00:07:48.240 --> 00:07:55.680
almost done so our maximum core managed to reach 70

00:07:53.440 --> 00:08:01.199
degrees we've got another one at 69 another one at 68 68 67

00:07:59.520 --> 00:08:04.960
yeah i mean he's coming back with his trusty

00:08:03.039 --> 00:08:08.400
calculator but i think i've already determined that we're higher science

00:08:06.639 --> 00:08:12.400
says it's worse yep two and a half degrees worse yep bummer

00:08:10.800 --> 00:08:15.759
this situation could only get better though right should we turn on the overclock

00:08:14.800 --> 00:08:20.800
yes so one of the special things about techs

00:08:18.319 --> 00:08:26.400
is that from my understanding if you overwhelm them so you have like

00:08:25.039 --> 00:08:29.680
too much heat they actually eventually become an

00:08:28.240 --> 00:08:32.800
insulator i'm hoping that doesn't happen but uh

00:08:31.440 --> 00:08:36.080
what do our CPU temps look like now we're 104 right now

00:08:37.200 --> 00:08:44.880
106. hey it's trying hard yeah i wonder

00:08:41.839 --> 00:08:44.880
how it's looking there

00:08:45.920 --> 00:08:50.880
um i don't know if this is accurate because i don't know

00:08:49.360 --> 00:08:55.120
if it's just bouncing around but that looks like 50 degrees on top of the

00:08:53.440 --> 00:08:57.920
CPU there oh we're at a hunt oh

00:08:56.959 --> 00:09:01.839
it's it's hit the thermal max i'm guessing

00:09:00.080 --> 00:09:06.240
that it's down clock now oh it hasn't yet yeah it's down clocking now

00:09:03.680 --> 00:09:11.120
everything's at like 110 degrees um fortunately

00:09:07.680 --> 00:09:11.120
we always had a backup plan

00:09:11.279 --> 00:09:14.880
just shutting it down

00:09:14.880 --> 00:09:20.880
okay so while we were removing this this is

00:09:18.480 --> 00:09:24.959
absolutely fascinating now what i was expecting

00:09:22.399 --> 00:09:29.600
was for all of our heat sinks and heat pipes over here to be cooling the hot

00:09:27.279 --> 00:09:32.480
side of the tech but alex pointed out that it actually works a little bit

00:09:30.720 --> 00:09:36.800
differently than that yeah it looks like this entire side

00:09:34.800 --> 00:09:41.760
is just working like a regular air cooler and whatever's left over

00:09:39.519 --> 00:09:44.640
after those heat pipes is then being cooled

00:09:42.880 --> 00:09:49.040
by the tech which is putting all that heat into the other

00:09:46.240 --> 00:09:51.440
side right so our tech is actually sitting in between

00:09:50.560 --> 00:09:57.760
two quad heat pipe single tower coolers

00:09:54.959 --> 00:10:03.279
so effectively this one is cooling the hot side of our tech and this one is

00:10:00.399 --> 00:10:08.000
just cooling the CPU directly with the cold side of the tech also cooling this

00:10:05.920 --> 00:10:10.800
plate from right here in the middle yeah i feel like they were just concerned

00:10:09.120 --> 00:10:13.760
that your average CPU would overwhelm the tech which makes sense because it's

00:10:12.399 --> 00:10:17.120
only 40 watts right and

00:10:15.440 --> 00:10:22.720
that would explain why it didn't just completely blow up yeah

00:10:19.440 --> 00:10:25.360
and movie magic everything is different

00:10:22.720 --> 00:10:29.600
so we have a whole water cooling loop just on the table here 360 rad costs

00:10:27.680 --> 00:10:33.600
about the same as our two peltier units it's already been pre-tested we have a

00:10:30.959 --> 00:10:39.760
new overclock that pushes this to its limits nice and it's all tested uh so

00:10:37.839 --> 00:10:44.000
that's the same price as this which means that these two have to keep up

00:10:41.839 --> 00:10:49.040
with that correct and like the RGB is included in the price so yeah the first

00:10:46.720 --> 00:10:53.200
thing i notice about these is that while they are fairly pre-done as a solution

00:10:51.920 --> 00:10:58.480
for the user um they don't have connectors on them

00:10:57.200 --> 00:11:05.120
beautiful okay snip me like my doctor did it

00:11:02.800 --> 00:11:10.480
okay we need we need to rethink this everyone's just shocked that

00:11:07.600 --> 00:11:13.600
doing things the correct way is easier i'm shocked

00:11:12.000 --> 00:11:18.399
yeah this is you know after the crap you gave me about my soldering that is really not a lot better

00:11:16.560 --> 00:11:21.760
yeah it's not heating up the way that i would like it to want some electrical

00:11:20.480 --> 00:11:27.040
tape yep i mean once you wrap it in enough electrical tape no one can tell

00:11:25.200 --> 00:11:30.800
you're soldering job okay in all seriousness though guys yes

00:11:29.120 --> 00:11:36.160
this is really jank and no neither alex nor i would ever

00:11:33.440 --> 00:11:41.200
deploy something like this in like a 24 7 application but this will run for

00:11:39.120 --> 00:11:46.399
quite literally five to ten minutes and we have a fire extinguisher right there

00:11:44.079 --> 00:11:51.920
okay wow that immediately got really cold

00:11:49.519 --> 00:11:58.240
wow eighteen fifteen thirteen eleven that's absolutely

00:11:55.760 --> 00:12:04.640
that's really cold we're gonna be below zero very soon

00:12:00.800 --> 00:12:06.560
uh yep we're below zero degrees

00:12:04.640 --> 00:12:08.839
so this could be a bad idea to keep my finger on here yeah what's it like on

00:12:08.240 --> 00:12:15.200
the bottom uh 60 60 70 something like that not bad it

00:12:13.200 --> 00:12:19.040
feels fine so guys what we're looking at here is a much more powerful peltier

00:12:16.959 --> 00:12:22.160
module you can see it has just larger gauge wires going into it it does seem

00:12:20.800 --> 00:12:26.079
to be a bit bigger than the one that was built into the heatsink and what it's

00:12:24.079 --> 00:12:30.560
doing is it's got its hot side over here which is being cooled by this double

00:12:27.680 --> 00:12:34.399
tower cooler with 392 millimeter fans and then it's got its cold side over

00:12:32.399 --> 00:12:39.600
here with just this rudimentary water block that is really quite frosty you

00:12:37.279 --> 00:12:42.560
can actually see there's frost forming on it and i'm leaving fingerprints

00:12:40.959 --> 00:12:47.040
behind so that's going to chill our water and this is going to dissipate the

00:12:44.639 --> 00:12:52.240
heat of our peltier module and our CPU to the surrounding air also it's

00:12:48.720 --> 00:12:53.839
currently drawing 301 watts not bad yeah

00:12:52.240 --> 00:12:57.839
instead of necessarily trying to have it at the highest point and like minimize

00:12:55.680 --> 00:13:02.000
water loss that way what if we just

00:12:59.200 --> 00:13:05.519
cut the tube and then i just jam this on there

00:13:02.720 --> 00:13:09.120
um this is a quick connection sure okay so actually oh pinch it pinch it

00:13:08.000 --> 00:13:13.440
wait wait wait wait don't don't lift that up not too high this is not half

00:13:11.200 --> 00:13:16.800
inch tubing okay

00:13:14.720 --> 00:13:22.160
okay let's keep that oh wow

00:13:18.240 --> 00:13:24.959
that is not coming off so here's an idea

00:13:22.160 --> 00:13:28.959
yeah should we just get this out of here um

00:13:26.320 --> 00:13:34.240
what's attached okay now that looked really jank but

00:13:30.720 --> 00:13:37.200
that's how much water we lost

00:13:34.240 --> 00:13:37.200
yeah we're basically pros

00:13:38.079 --> 00:13:44.639
but that was intentional so how proud are we right now we

00:13:41.200 --> 00:13:46.079
basically invented a cool it boreous

00:13:44.639 --> 00:13:51.040
not very now our idle temps are looking pretty

00:13:48.160 --> 00:13:55.120
fine 26 27 27. so actually it is lower now it's 23. oh

00:13:54.240 --> 00:13:59.760
wow actually it's dropping really fast yeah

00:13:57.440 --> 00:14:04.240
our lowest core is at 22 already all right f12

00:14:01.440 --> 00:14:04.240
yep here it goes

00:14:04.480 --> 00:14:11.040
so we're looking at a maximum temperature of 84 to beat

00:14:08.320 --> 00:14:15.040
80.7 is our average on all cores remember there's two chillers in series

00:14:12.720 --> 00:14:19.839
here so we want this one versus this one so this one's like

00:14:17.600 --> 00:14:22.480
26. and this guy

00:14:23.279 --> 00:14:31.199
come on it's like

00:14:27.199 --> 00:14:33.040
it's like 26 also

00:14:31.199 --> 00:14:37.600
well it's trying they're trying there bud oh our render's

00:14:35.199 --> 00:14:43.680
done oh so our maximum on the hottest core was 80. however

00:14:41.199 --> 00:14:46.800
that doesn't tell the whole story because

00:14:44.399 --> 00:14:51.519
we actually started with our water chilled to sub-ambient

00:14:49.040 --> 00:14:55.199
and we could see as the test ran that it was definitely heating up so we need to

00:14:53.199 --> 00:15:00.639
do a longer test yeah so how'd we do

00:14:56.880 --> 00:15:03.680
oh yeah we had to beat 84 degrees

00:15:00.639 --> 00:15:06.000
and we hit what

00:15:03.680 --> 00:15:10.720
94 that's so that's not great so all that's

00:15:08.639 --> 00:15:14.639
left after of course zipping up my stealth hoodie and telling you guys it's

00:15:12.160 --> 00:15:18.240
available on lttstore.com is to walk through

00:15:16.240 --> 00:15:22.800
why this is a bad idea so there's a couple of things number one

00:15:20.000 --> 00:15:26.959
it actually isn't any more compact even though the peltier module itself is

00:15:24.880 --> 00:15:32.560
quite small because you've got to cool all that extra heat number two is the

00:15:29.519 --> 00:15:35.199
extra heat and therefore noise number

00:15:32.560 --> 00:15:40.000
three is the cost for the same price we were able to get this radiator along

00:15:37.199 --> 00:15:45.440
with like RGB fans and stuff and number four is of course the power consumption

00:15:42.800 --> 00:15:50.800
this at full blast consumes about 10 watts while this consumes about

00:15:48.759 --> 00:15:54.399
300 watts so the thing with tex is that yeah it's

00:15:52.399 --> 00:15:58.079
cool that you can reach sub-ambient temperatures as long as there's not much

00:15:55.839 --> 00:16:02.000
heat load but if as soon as you fire up something intensive like a render your

00:16:00.320 --> 00:16:06.000
temperatures go higher than just with a traditional water cooling radiator then

00:16:04.160 --> 00:16:10.480
that's kind of a bummer but guys make sure you're subscribed so you

00:16:08.639 --> 00:16:16.399
don't miss this video because that doesn't mean that peltiers are

00:16:13.040 --> 00:16:18.480
necessarily a bad idea the way that they

00:16:16.399 --> 00:16:23.199
were in this video now the way we used to do it in the old days was we'd take a

00:16:20.639 --> 00:16:28.240
peltier and put it directly between the CPU block and the CPU taking the cooling

00:16:26.399 --> 00:16:33.279
right where it's needed now the problem was that cpus outpaced peltiers in terms

00:16:31.680 --> 00:16:38.399
of how much heat they were outputting and what kind of peltiers you could get

00:16:35.120 --> 00:16:39.360
so it became just impractical but alex

00:16:38.399 --> 00:16:44.720
found oh yeah we found one that's 545 watts

00:16:42.480 --> 00:16:49.279
and draws 32 amps so that's on its way from ebay that's

00:16:46.720 --> 00:16:53.279
going to be a future video subscribe hit that bell so you don't miss it and we

00:16:50.720 --> 00:16:58.320
will see you there in maybe bad cooling ideas episode two

00:16:56.320 --> 00:17:03.759
yeah that might be a good idea and maybe soon and maybe not because ebay shipping

00:17:02.000 --> 00:17:08.079
speaking of ebay shipping i'm bringing this sponsor segway right

00:17:05.919 --> 00:17:11.280
to you right now faster than ebay shipping
