00:00:00.080 --> 00:00:06.720
youtuber tech ingredients made some pretty bold claims recently saying that

00:00:04.400 --> 00:00:12.320
their homemade thermal compound can outperform commercial solutions like

00:00:09.440 --> 00:00:17.359
arctic silver so naturally immediately after that video drop we received dozens

00:00:14.480 --> 00:00:21.520
of emails asking us to test it out i mean arctic silver has silver in it

00:00:20.000 --> 00:00:26.480
could anything be more conductive than silver tech ingredients sure think so so

00:00:24.240 --> 00:00:30.000
we got our hands on it and we are going to be

00:00:27.519 --> 00:00:33.360
with full attention to all the warnings trying this

00:00:31.519 --> 00:00:38.800
out and the video is brought to you by aorus

00:00:36.239 --> 00:00:42.800
the aorus 15g features an Intel 10th gen processor with strong battery life and

00:00:40.719 --> 00:00:47.040
performance and tons of features check it out today at the link in the video

00:00:44.480 --> 00:00:47.040
description

00:00:54.160 --> 00:01:00.399
the craziest part of this is not only does tech ingredients say that this will

00:00:58.160 --> 00:01:04.799
outperform a commercial solution he also says that you can make it at home as

00:01:02.640 --> 00:01:10.080
long as you've got some dendritic copper epoxy graphene diamond and access to a

00:01:08.159 --> 00:01:14.000
high-powered ultrasound or a cell disrupter we just went ahead and paid

00:01:12.080 --> 00:01:18.240
the 20 bucks or whatever it was to have him send it over now i'm really excited

00:01:15.840 --> 00:01:22.720
to test this but there is one major caveat as is laid out in the

00:01:20.000 --> 00:01:27.439
instructions this bond is permanent meaning this is more like a thermal

00:01:24.400 --> 00:01:28.960
epoxy and less like a thermal paste so

00:01:27.439 --> 00:01:33.759
when i was putting together my test bench for today i had to consider a

00:01:31.280 --> 00:01:37.439
couple of things number one is i needed something that output enough heat that i

00:01:36.159 --> 00:01:43.840
was going to be able to tell the difference between my reference thermal solutions over here

00:01:41.360 --> 00:01:47.040
and the tech ingredients thermal epoxy and number two i needed a test bench

00:01:45.520 --> 00:01:52.960
where i wouldn't be too choked up if my CPU was permanently bonded to the bottom

00:01:49.680 --> 00:01:54.240
of my cooler so i chose an AMD fx 8150

00:01:52.960 --> 00:01:59.280
this thing was known for being an absolute inferno of a chip and

00:01:57.040 --> 00:02:01.040
not real fast and this

00:02:00.159 --> 00:02:06.000
thing this is the thermaltake black widow spin

00:02:04.159 --> 00:02:10.959
q i'm not actually sure what it's called it seems to have two names

00:02:08.399 --> 00:02:14.959
universal CPU cooler been a while since i've dragged the old crosshair four out

00:02:13.040 --> 00:02:18.319
of mothballs one thing that i went and grabbed is

00:02:16.560 --> 00:02:22.160
some of these Noctua cleaning wipes normally i'm pretty loosey-goosey about

00:02:20.319 --> 00:02:25.599
the way that i clean cpus in between thermal paste applications but because

00:02:23.920 --> 00:02:29.520
we're actually trying to measure the difference in performance between

00:02:27.120 --> 00:02:33.440
thermal pastes it's pretty important that we do a great job of cleaning our

00:02:31.520 --> 00:02:37.040
CPU here let's get some RAM installed throw a period appropriate graphics card

00:02:35.519 --> 00:02:41.519
on here we're going to start with what i'm expecting to be the least performant

00:02:39.440 --> 00:02:46.800
thermal interface this is the innovation cooling ic graphite thermal pad and to

00:02:44.640 --> 00:02:50.640
be clear i'm not saying it's bad it's just that the sales pitch for these pads

00:02:49.040 --> 00:02:54.959
is that they're reusable and they don't make a mess not that their performance

00:02:52.959 --> 00:03:00.000
is right up there with the top thermal pastes so we just plonk that on there

00:02:57.360 --> 00:03:03.760
and we're ready to mount our cooler oh i actually lied to you guys a little bit

00:03:02.319 --> 00:03:07.280
i think this is going to be the least performant

00:03:05.519 --> 00:03:11.440
thermal interface let's try this one too this is the included thermal paste with

00:03:09.280 --> 00:03:16.400
this uh kind of cheapo cooler one thing that's nice about using an AMD CPU for

00:03:14.080 --> 00:03:20.560
this that uses the clip based hold down is we're gonna have identical mounting

00:03:18.159 --> 00:03:24.959
pressure on all of our thermal interface materials there's no real room for user

00:03:22.879 --> 00:03:27.920
error because you can't over or under tighten it to make our lives easier

00:03:26.640 --> 00:03:31.360
we're not going to bother with idle temperatures that's not really where the

00:03:29.920 --> 00:03:36.000
men get separated from the boys when it comes to thermal solutions anyway so

00:03:33.599 --> 00:03:39.760
let's go ahead and fire up a classic stress test for a classic

00:03:38.560 --> 00:03:47.120
CPU smallest fft eight threads

00:03:44.159 --> 00:03:51.120
and then we're gonna wait until the CPU temperature reaches

00:03:49.200 --> 00:03:54.080
about a stable point and we're going to go ahead and we're going to click this

00:03:52.239 --> 00:03:58.799
clock down here to reset our average values and let it run for two or three

00:03:56.080 --> 00:04:04.879
minutes 50 degrees under load qualified as a inferno of a CPU now we've got you

00:04:02.239 --> 00:04:09.959
know the Intel 10th gen i'm a little rusty on my fx overclocking

00:04:07.200 --> 00:04:15.040
but about 4.5 gigahertz with about 1.42 volts or so after some trial and

00:04:13.040 --> 00:04:20.840
error where we got reacquainted with the fx 8150s 70 degree celsius maximum

00:04:18.799 --> 00:04:27.600
temperature we settled on 1.475 volts with turbo disabled and 4

00:04:24.479 --> 00:04:30.560
gigahertz clock speed giving us about

00:04:27.600 --> 00:04:35.520
68 degrees under load with our thermal pad so now what we're gonna do is reset

00:04:32.960 --> 00:04:39.680
our timer and take an average over about two minutes after a little over two

00:04:37.199 --> 00:04:46.080
minutes we've got no thermal throttling an average temperature of 67.7 degrees

00:04:42.560 --> 00:04:48.800
celsius and a maximum of 69.1 nice

00:04:46.080 --> 00:04:51.600
now for our next thermal compound this is nice we don't have to clean it

00:04:50.080 --> 00:04:55.040
because all we had on there was one of these thermal pads but we're definitely

00:04:53.759 --> 00:04:59.520
going to have to clean it after our next attempt what do you think andy

00:04:56.960 --> 00:05:04.240
quality thermal compound or the gross included garbage

00:05:02.160 --> 00:05:07.759
let's do the included garbage baby now at this point of the game i could wait

00:05:06.000 --> 00:05:12.080
around for the temperature to reach equilibrium or

00:05:09.360 --> 00:05:17.120
i could take nature into my own hands by running the CPU at effectively what is a

00:05:14.400 --> 00:05:20.240
greater ambient temperature we can cause it to heat up to approximately where we

00:05:18.800 --> 00:05:25.280
think it's going to end up and then it should normalize a little bit

00:05:22.840 --> 00:05:29.680
sooner it's a free tech tip hey look how fast it's heating up the system works

00:05:27.759 --> 00:05:34.320
meanwhile steve over at gamer's nexus with like liquid nitrogen pots

00:05:32.240 --> 00:05:38.800
wow i knew that these thermal pads were optimized for convenience rather than

00:05:36.160 --> 00:05:44.479
performance but dang even the generic stuff included with our heatsink is that

00:05:41.039 --> 00:05:46.560
uh what's my average here 60.1 now i'm

00:05:44.479 --> 00:05:49.759
really not sure what to expect from a quality thermal paste are we gonna drop

00:05:48.400 --> 00:05:53.919
like another seven degrees

00:05:51.440 --> 00:05:59.120
kind of doubt that oh i always forget about this even though it's actually the

00:05:55.919 --> 00:06:01.280
reason i chose an AMD chip because

00:05:59.120 --> 00:06:04.880
obviously once the CPU and the heatsink are glued together i'm not going to be

00:06:02.800 --> 00:06:07.919
able to get at the release mechanism so i wanted something that worst case

00:06:06.479 --> 00:06:12.160
scenario i could just yank out of the socket you gotta you gotta twist ladies

00:06:10.000 --> 00:06:15.120
and gentlemen there that's better let's get this bad boy cleaned up he's

00:06:13.520 --> 00:06:20.319
knocked to a cleaning cloth or the next level that is a clean

00:06:17.440 --> 00:06:24.960
fx CPU ladies and gentlemen no harm no foul do we really need to use two like

00:06:22.639 --> 00:06:30.160
high quality thermal pastes i think just one is fine uh do you want Noctua or mx4

00:06:28.960 --> 00:06:34.319
all right so i want a very similar amount but i'm

00:06:32.400 --> 00:06:39.280
also going to make sure that i spread it out man it's weird seeing the old green

00:06:36.960 --> 00:06:43.120
AMD logo here on the desktop the shortcut is the old green logo i like

00:06:40.960 --> 00:06:46.240
totally forgot it used to be green and then they started competing in graphics

00:06:44.479 --> 00:06:53.919
and it's like oh well we can't have team green and team green bang on andy

00:06:49.800 --> 00:06:55.280
59.1 you nailed it one degree better

00:06:53.919 --> 00:07:00.560
before using this product you might want to review some principles of using thermal interface materials demonstrated

00:06:58.319 --> 00:07:05.440
in our tech ingredients video wear gloves protect your work surface

00:07:02.000 --> 00:07:05.440
with some disposable plastic film

00:07:06.240 --> 00:07:10.960
contact with epoxy can irritate the skin got it

00:07:09.759 --> 00:07:14.479
after preparing and cleaning the surfaces remove the caps on the syringes

00:07:12.800 --> 00:07:18.639
and eject the quantity you plan to use the mixing ratio is three parts large

00:07:16.400 --> 00:07:22.639
orange syringe and one part small black syringe watch out the orange syringe is

00:07:21.039 --> 00:07:26.319
more viscous so uh

00:07:24.160 --> 00:07:29.680
we'll need to be a little bit careful to get the right quantities here

00:07:28.639 --> 00:07:33.599
too much dang it they even warned me i knew this

00:07:32.000 --> 00:07:37.039
was gonna happen does that look about twice the size of

00:07:35.360 --> 00:07:39.919
my orange ones what do you think

00:07:38.400 --> 00:07:42.800
yeah okay we'll do three more orange ones

00:07:42.840 --> 00:07:48.240
good i love science-y instructions written

00:07:46.240 --> 00:07:52.160
for scientists stir the components thoroughly until the color is a

00:07:49.440 --> 00:07:57.120
completely homogeneous dark brown and then mix for another 30 seconds

00:07:54.560 --> 00:08:02.479
i'm going to use this plastic mcdonald's knife homogeneous dark brown

00:08:00.800 --> 00:08:06.960
wow it's kind of grainy which i guess makes sense given that it's made of like

00:08:05.199 --> 00:08:11.120
little grains of diamond graphite and

00:08:09.120 --> 00:08:15.520
indirect copper okay we've got to mix it for another 30 seconds though i'm very

00:08:13.199 --> 00:08:19.599
specific about that i am going to follow instructions for

00:08:17.520 --> 00:08:24.800
once in my life because this stuff seems like serious science shiz here

00:08:22.479 --> 00:08:28.479
all right wow it really starts to thicken up a bit there

00:08:26.879 --> 00:08:32.880
interesting okay that seems like about 30 seconds

00:08:31.360 --> 00:08:37.839
more of mixing wow all right cool apparently we've got about 45

00:08:36.159 --> 00:08:44.560
minutes before we can't work with it anymore now we need to put a thin layer

00:08:40.399 --> 00:08:45.440
of this stuff on each of our surfaces

00:08:44.560 --> 00:08:51.200
this is not the best spready spreading tool

00:08:49.279 --> 00:08:54.720
um you know what i'm just going to use my glove so those are on there now get

00:08:53.279 --> 00:09:00.800
this there's an element to the instructions that i actually didn't read until now

00:08:59.120 --> 00:09:04.880
once they're on there you're going to want to grab a

00:09:02.839 --> 00:09:09.200
fingernail-sized piece of medium sandpaper

00:09:06.240 --> 00:09:14.800
and abrade the epoxy mixture for a few seconds into each surface before placing

00:09:12.080 --> 00:09:19.120
them into contact oh yeah here's some 400 grit sandpaper which i guess is

00:09:17.200 --> 00:09:22.800
medium-ish this hurts me so much we're going

00:09:20.959 --> 00:09:26.880
heavier guys i made the mistake of following the written instructions

00:09:24.640 --> 00:09:32.880
without looking carefully at the video instructions and it seems like he put it

00:09:29.040 --> 00:09:34.000
on much much heavier than i expected so

00:09:32.880 --> 00:09:37.519
i'm just going to go ahead i'm going to mix up a whole bunch more and we're

00:09:36.160 --> 00:09:40.720
going to try and get this on there before it cures so we're going heavier

00:09:39.760 --> 00:09:44.720
here we're going heavier here we go

00:09:46.480 --> 00:09:51.839
i guess this is the part of the video where i acknowledge that we shot this

00:09:49.920 --> 00:09:56.399
over a couple of days because of that whole issue with the

00:09:53.440 --> 00:10:01.680
69 degree thermal limit so i'm putting this on as far as i can

00:09:59.360 --> 00:10:06.160
tell correctly from tech ingredients video obviously

00:10:03.760 --> 00:10:09.680
he didn't apply it to a CPU but hey that's what you guys need me for

00:10:07.680 --> 00:10:11.920
it's definitely on there andy what's going to happen

00:10:10.880 --> 00:10:15.600
no no what's actually going to happen do you think it's going to outperform the

00:10:14.320 --> 00:10:21.279
paste it's glue it's thermal glue dendritic copper

00:10:19.360 --> 00:10:24.720
diamond now i hate this when you've got one

00:10:23.200 --> 00:10:28.079
dirty finger from what you were doing before and you got to wash your whole

00:10:26.240 --> 00:10:33.120
hand you know i'm just going to take it to 59 because then we're going to see

00:10:30.320 --> 00:10:36.720
whether it keeps going up or goes down this is interesting it's a good thing we

00:10:34.959 --> 00:10:40.720
left a little bit of headroom between the thermal pad and the 70 degree

00:10:38.480 --> 00:10:43.600
thermal throttling limit because you can see here

00:10:41.760 --> 00:10:47.680
we are actually in between pad performance and that 70 degree limit

00:10:46.160 --> 00:10:50.800
with the epoxy fortunately we're not throttling so this

00:10:49.519 --> 00:10:55.920
should be the same amount of thermal output and our result should still be valid

00:10:53.839 --> 00:11:00.320
i spoke too soon during our two minute run we thermal throttled you can see all

00:10:58.000 --> 00:11:05.279
these cores dropped down to 1.4 gigahertz they ramped back up you can

00:11:02.480 --> 00:11:08.079
see we're running at full speed now but

00:11:06.079 --> 00:11:12.480
it clearly was outperformed by every other solution

00:11:10.160 --> 00:11:15.519
we tested now i kind of feel bad about the way i

00:11:13.600 --> 00:11:19.600
presented the intro because i had intended to like seem skeptical but i

00:11:17.519 --> 00:11:22.480
actually thought that this was gonna outperform it i didn't mean for this to

00:11:21.279 --> 00:11:29.519
just be like dunking on their thermal compound it's the next day

00:11:27.040 --> 00:11:34.880
it occurs to me that maybe our thermal epoxy doesn't perform at peak efficiency

00:11:32.240 --> 00:11:38.079
until it's actually hardened so we're gonna fire the machine back up i let it

00:11:37.200 --> 00:11:44.079
sit not running because i i wasn't sure how

00:11:41.120 --> 00:11:47.360
having it be hot would affect the curing and we're going to take one more crack

00:11:45.839 --> 00:11:52.720
at it here just checking the numbers from yesterday i think it's going to perform quite well compared to them want

00:11:50.880 --> 00:11:56.880
to see a nice flat line before we start our two-minute run though it starts out

00:11:54.720 --> 00:12:00.320
high from our heat gun shortcut then comes back down

00:11:58.480 --> 00:12:04.240
and now it's creeping its way back up again i'm trying to wrap my brain around

00:12:02.320 --> 00:12:08.800
this behavior how can you have the same thermal interface material in there that

00:12:07.040 --> 00:12:11.600
performs differently over time

00:12:10.720 --> 00:12:15.279
it seems to be very clearly doing that

00:12:13.760 --> 00:12:19.120
though maybe tech ingredients could do a follow-up explaining this i'd love to

00:12:16.880 --> 00:12:22.920
know like is it expanding how long should it take to reach equilibrium

00:12:24.800 --> 00:12:30.240
i'm disappointed i was ready to come in this morning and say

00:12:28.639 --> 00:12:35.200
well stupid me i shouldn't have been testing it before it was cured anyway

00:12:32.959 --> 00:12:39.120
but we're actually seeing pretty much the same behavior at this point we just

00:12:36.959 --> 00:12:43.040
touched 68 degrees for the first time a little while back there and you can see

00:12:41.200 --> 00:12:47.279
we've got a pretty consistent trend upward right as i was saying that it

00:12:45.519 --> 00:12:52.399
thermal throttled so two of our cores dropped down to 1.4 gigahertz

00:12:50.079 --> 00:12:57.440
that we can't give it a temperature score at that point that's a just a fail

00:12:55.600 --> 00:13:01.600
with thermal performance worse than even our graphite pad it's safe to say i

00:12:59.760 --> 00:13:06.399
won't be recommending tech ingredients as thermal epoxy for your CPU any time

00:13:04.320 --> 00:13:11.120
soon but it's also safe to say that they never recommended it for that either

00:13:08.720 --> 00:13:15.440
it's for situations where you cannot use a higher performance thermal grease and

00:13:13.519 --> 00:13:20.320
you know what i think my expectations were probably a bit unreasonable here

00:13:17.760 --> 00:13:24.959
but given that the only reference that i had for its relatively high performance

00:13:23.200 --> 00:13:28.880
was a competing thermal epoxy that nobody in their right mind would put on

00:13:26.639 --> 00:13:32.399
a CPU i just didn't really have a frame of reference and neither did you so i

00:13:30.480 --> 00:13:38.480
can understand what you guys wanted me to test it for all i can hope now is

00:13:35.440 --> 00:13:40.160
that its performance as an epoxy

00:13:38.480 --> 00:13:46.160
is disappointing and at least i can get my CPU back oh

00:13:42.800 --> 00:13:47.440
okay i think it's glued but as we've

00:13:46.160 --> 00:13:52.000
seen before it should still be possible to pull the CPU out of the socket yeah here we go so

00:13:50.800 --> 00:13:56.000
it looks like a we definitely had enough to cover the

00:13:54.320 --> 00:13:59.680
entire ihs because we've got that seepage all the way around the edge and

00:13:58.880 --> 00:14:04.800
b we've obviously got a fair amount of mounting pressure on here because

00:14:02.959 --> 00:14:08.480
otherwise why would it seep out from around the edges there remember how i

00:14:06.560 --> 00:14:14.160
was able to twist off the old thermal paste well the epoxy component works

00:14:12.399 --> 00:14:17.839
shucks ah oh my goodness

00:14:15.600 --> 00:14:21.120
like look how durable this stuff is i'm scratching at it with a knife and it's

00:14:19.120 --> 00:14:26.440
not even entirely coming off i know sometimes blunt force can be better for

00:14:23.040 --> 00:14:26.440
cracking epoxy

00:14:30.959 --> 00:14:37.360
so we have no choice but to keep going enter

00:14:34.320 --> 00:14:37.360
the power fist

00:14:41.279 --> 00:14:46.800
wow i think it's kind of a

00:14:44.480 --> 00:14:51.600
30 chance this thing still works after what just happened to it but what

00:14:48.320 --> 00:14:55.199
happens now if i just put like a

00:14:51.600 --> 00:14:58.560
thermal pad on it oh wow

00:14:55.199 --> 00:15:00.720
that's bent i'm not even gonna try to

00:14:58.560 --> 00:15:06.079
mount it properly and like i'm just gonna see if it you know posts well the

00:15:03.519 --> 00:15:09.839
CPU still works i mean we can never you know use it for certain kinds of testing

00:15:08.000 --> 00:15:14.000
anymore because it's covered in epoxy but at least i can give it back to the

00:15:11.440 --> 00:15:18.880
inventory guys knowing that my inventory checkout sheet is clear
