00:00:00.400 --> 00:00:07.359
they finally did it 10 years ago i complained to Noctua that

00:00:04.640 --> 00:00:13.440
their products were great but simply too ugly to use for my own personal projects

00:00:10.559 --> 00:00:18.240
well back in 2015 we partnered with them to launch their first all black consumer

00:00:16.240 --> 00:00:22.560
fans which was a big step in the right direction and now

00:00:20.320 --> 00:00:29.039
four years later we're back at it with something even bigger

00:00:26.080 --> 00:00:38.239
not this this is ugly meat the LTT editions of Noctua's first ever

00:00:33.520 --> 00:00:40.559
lineup of all black coolers the first 5

00:00:38.239 --> 00:00:47.120
000 units of each the chromax black nhd15 and nhu 12s will have some special

00:00:44.559 --> 00:00:50.399
extras included and will help support us here at LTT

00:00:48.640 --> 00:00:55.680
so in today's video we're going to give you guys a close look at them and

00:00:53.199 --> 00:01:00.719
also make sure that they match both the excellent thermal performance and

00:00:58.480 --> 00:01:06.159
low sound levels that we have come to expect from Noctua's ugly products

00:01:04.720 --> 00:01:11.680
speaking of things you should have come to expect this segway to our sponsor glassware

00:01:09.760 --> 00:01:15.600
with glasswire you can instantly see your current and past network activity

00:01:13.520 --> 00:01:20.240
detect malware and block badly behaving apps on your pc or Android device use

00:01:18.080 --> 00:01:27.099
offer code Linus to get 25 off at the link below

00:01:30.159 --> 00:01:36.720
now it's no secret that i am a huge knock to a fan boy

00:01:37.600 --> 00:01:43.280
sorry puns aside any fandom that i have

00:01:40.880 --> 00:01:47.600
of any company is going to be out of respect not because there's like an

00:01:45.680 --> 00:01:53.439
emotional attachment and there's a reason that i hold Noctua in such high

00:01:50.399 --> 00:01:55.119
regard their secu firm 2 mounting system

00:01:53.439 --> 00:02:00.960
which by the way like the fan included and the heatsink

00:01:57.600 --> 00:02:03.439
itself is now all black down to every

00:02:00.960 --> 00:02:08.479
single mounting plate and screw is still by far my favorite solution

00:02:06.159 --> 00:02:14.239
when it comes to keeping a large heavy tower cooler firmly planted on a CPU and

00:02:12.000 --> 00:02:20.400
as we showed in our recent video their performance is on par or better than aio

00:02:18.160 --> 00:02:25.440
water coolers in the same price bracket or in some cases even higher ones and

00:02:23.440 --> 00:02:29.680
their ugly fans are the standard that other fans are measured to from a

00:02:27.520 --> 00:02:34.000
performance perspective anyway the only reason that their products have

00:02:31.599 --> 00:02:36.640
been relegated to test bench duty for me is that

00:02:35.120 --> 00:02:42.080
i confess i like a little bit of flash with my

00:02:38.879 --> 00:02:44.319
dash and until now they haven't had

00:02:42.080 --> 00:02:47.680
anything in their CPU cooler lineup that's even

00:02:45.519 --> 00:02:52.080
close enough to the visual appeal of other solutions to justify the couple

00:02:50.080 --> 00:02:55.920
degrees of better performance or few decibels of lower acoustics

00:02:54.480 --> 00:03:01.680
at least until now

00:02:58.879 --> 00:03:01.680
let's open it up

00:03:02.319 --> 00:03:09.519
it looks so good there's nothing on it

00:03:07.120 --> 00:03:14.239
that isn't black wires sleeving heat shrink connectors

00:03:12.720 --> 00:03:21.040
screws even the retainers here are black which

00:03:18.159 --> 00:03:25.519
has gotta kinda make you wonder if

00:03:22.400 --> 00:03:27.760
this was such an obvious problem

00:03:25.519 --> 00:03:30.560
and such an easy solution why didn't they hurry up and do this

00:03:29.519 --> 00:03:36.480
before well because as it turns out it's actually

00:03:34.000 --> 00:03:41.680
not an especially easy solution now there are lots of different ways to

00:03:38.799 --> 00:03:45.360
attach heat pipes to a CPU cooler's base and the heat pipes are what are

00:03:43.200 --> 00:03:49.040
responsible for quickly moving the heat away from your processor to the cooling

00:03:47.440 --> 00:03:52.319
fins which are responsible for dissipating the heat to the surrounding

00:03:50.720 --> 00:03:58.159
air but no way of attaching them is as reliant

00:03:54.879 --> 00:04:00.720
or performant as soldering them

00:03:58.159 --> 00:04:04.239
now soldering heat pipes is already a tricky matter because

00:04:02.319 --> 00:04:09.200
think about it for a second these are sealed tubes with fluid inside that are

00:04:06.959 --> 00:04:13.360
designed to transfer heat away from where it's being applied so doing it

00:04:11.120 --> 00:04:16.959
safely without them exploding isn't as simple as whipping out a torch and just

00:04:15.680 --> 00:04:22.079
going for it so then wait

00:04:19.440 --> 00:04:28.080
you want to put a coating on these things adding yet another layer of

00:04:24.479 --> 00:04:30.320
complexity for what just for looks are

00:04:28.080 --> 00:04:33.199
you crazy that's a very knock to a way of thinking

00:04:32.160 --> 00:04:38.960
but i and the thousands of other enthusiasts

00:04:35.919 --> 00:04:41.840
who sadly do care about these things

00:04:38.960 --> 00:04:46.240
finally got through to them so much of the r d for this product went into

00:04:43.759 --> 00:04:51.840
finding a way to manufacture the chromax black lineup with the same performance

00:04:48.800 --> 00:04:54.160
and consistency as the regular versions

00:04:51.840 --> 00:05:01.120
that don't have to deal with that added layer of complexity here and

00:04:57.199 --> 00:05:04.000
Noctua claims that they did it so to

00:05:01.120 --> 00:05:09.840
validate their claims we have both the big boy nhd15 dual tower cooler and for

00:05:08.000 --> 00:05:15.120
the more space conscious of you we also have the nhu 12s with a single 120

00:05:13.120 --> 00:05:21.280
millimeter fan and a heck and ton of clearance for your pci slots and your

00:05:18.320 --> 00:05:26.320
RAM there's an extra little note in the box a little letter from LTT as well as

00:05:24.400 --> 00:05:29.680
some LTT stickers for the hubs of your fans or you can throw them on your case

00:05:27.680 --> 00:05:34.160
if you want and these sexy orange rubber

00:05:32.240 --> 00:05:39.199
anti-vibration pads of course the original black ones are also included in

00:05:36.560 --> 00:05:42.400
the box there's also an nhd9i but there's no LTT edition of that one

00:05:41.680 --> 00:05:47.440
so that was some movie magic right there we have replaced the stock black pads with

00:05:46.000 --> 00:05:51.280
the orange ones so you can see what they're going to look like in their LTT

00:05:49.520 --> 00:05:55.600
edition goodness now let's head over to the workshop and

00:05:53.919 --> 00:05:59.039
make sure they're actually worth buying compared to the originals so step one of

00:05:57.600 --> 00:06:02.960
putting these things through their paces is building up a test bench that is

00:06:01.039 --> 00:06:08.840
really going to challenge them so this right here is Intel's furnace of a CPU

00:06:07.120 --> 00:06:13.600
the extreme edition 9980xe18 core and we're going to be

00:06:11.039 --> 00:06:18.319
using ida 64's stress test to compare both the

00:06:15.080 --> 00:06:19.039
ognhd15 and u12s

00:06:18.319 --> 00:06:24.960
to their new all black counterparts

00:06:22.400 --> 00:06:30.560
so for the sake of simplicity we actually tested our

00:06:27.520 --> 00:06:33.440
products as they came in the box so that

00:06:30.560 --> 00:06:36.800
is with only one fan installed and no low noise adapters

00:06:35.199 --> 00:06:42.479
this way we can also have a look at how much benefit there is to having two

00:06:38.960 --> 00:06:43.360
cooling towers versus just a single one

00:06:42.479 --> 00:06:50.160
all right so now it's time for the results guys first up thermals each of our coolers

00:06:48.160 --> 00:06:55.039
was allowed to run for 10 minutes to hit thermal equilibrium and we repeated the

00:06:52.240 --> 00:06:59.120
tests three times remounting the coolers between each run

00:06:56.560 --> 00:07:03.840
so between the two u12 s's our black cooler actually came out on top with an

00:07:01.360 --> 00:07:09.120
average temperature 1.7 degrees cooler than the raw version with the nhd15s

00:07:06.800 --> 00:07:14.080
however we saw the opposite with the raw cooler beating out the black version by

00:07:11.280 --> 00:07:17.360
about 1.3 degrees now here's the thing guys

00:07:14.880 --> 00:07:21.919
considering the 20 variability in RPM from one knock to a

00:07:20.400 --> 00:07:27.199
fan to the next that's their manufacturing tolerance and the variance

00:07:24.400 --> 00:07:32.400
that we saw from run to run particularly on our nhd15s we think it's safe to say

00:07:30.160 --> 00:07:37.039
at this point that buying black versus raw is not going to yield a performance

00:07:34.639 --> 00:07:41.840
difference one way or the other but that doesn't answer the question of

00:07:39.680 --> 00:07:45.759
how they compare acoustically the problem is we have no way of testing

00:07:43.919 --> 00:07:50.800
that here i mean even somewhere like this empty workshop has you know this

00:07:48.800 --> 00:07:55.360
transformer you hear that buzzing that is so much

00:07:53.199 --> 00:07:59.280
louder than these coolers that we would have no way of getting an accurate

00:07:56.879 --> 00:08:03.360
measurement of them fortunately we've got friends in high places and our

00:08:00.879 --> 00:08:08.400
buddies over at simon fraser university graciously gave us access to their world

00:08:05.840 --> 00:08:13.280
class satomo antenna testing chamber this chamber is normally used to map the

00:08:10.960 --> 00:08:18.400
transmission patterns of antenna designs for all types of devices from tiny iot

00:08:16.080 --> 00:08:23.039
things all the way up to satellites and it's actually a happy little accident

00:08:20.479 --> 00:08:27.360
that it happens to work so well for acoustic testing as it's designed to

00:08:25.520 --> 00:08:31.120
prevent radio waves from reflecting around the room as well as preventing

00:08:29.199 --> 00:08:37.279
any from entering from the outside it's actually one big faraday cage so we're

00:08:34.080 --> 00:08:39.039
back and the data is really interesting

00:08:37.279 --> 00:08:42.479
so once again there is a difference between our silver and our black

00:08:41.360 --> 00:08:48.000
heatsinks but this time the superior performance

00:08:45.920 --> 00:08:52.720
actually goes completely the other way around which appears to validate our

00:08:50.560 --> 00:08:57.120
previous theory that the temperature differences that we observed yesterday

00:08:55.360 --> 00:09:00.959
pretty much came down to the fans spinning a little slower or a little

00:08:58.880 --> 00:09:03.600
faster depending on the manufacturing tolerances

00:09:02.160 --> 00:09:08.240
so then bottom line they're as good as they're

00:09:05.440 --> 00:09:11.760
supposed to be so how do you get one great question

00:09:09.519 --> 00:09:16.880
the first couple batches of units out of Noctua's manufacturing facilities are

00:09:14.080 --> 00:09:20.720
all going to be LTT edition with the extra stickers the orange mounting pads

00:09:19.200 --> 00:09:25.680
and all that good stuff and these will exclusively be available on Noctua's

00:09:23.120 --> 00:09:29.519
official amazon stores while supplies last

00:09:26.640 --> 00:09:34.399
after october 22nd 2019 knoxville will begin shipping regular ones that are

00:09:31.839 --> 00:09:39.279
just all black and those may end up being mixed in with the LTT edition ones

00:09:37.120 --> 00:09:42.160
at the amazon warehouse after that time you'll need to check Noctua's ebay store

00:09:41.120 --> 00:09:46.399
where they're going to try and keep a few of these around even after that date

00:09:44.480 --> 00:09:49.839
for anyone who's a little late to the game

00:09:47.680 --> 00:09:53.760
speaking of late to the game i'm never late to the segway game

00:09:52.080 --> 00:09:57.279
make your walls look awesome with our sponsor for today's video display

00:09:55.839 --> 00:10:02.000
they're posters made out of metal they're three millimeters thick they've got bent edges so that you don't

00:10:00.240 --> 00:10:05.360
accidentally slice open your fingers and they've got a matte finish that looks

00:10:03.440 --> 00:10:08.959
absolutely fantastic the best thing about disc plate though is the mounting

00:10:07.360 --> 00:10:12.480
system they use a magnetic mounting system that makes it easy to swap out

00:10:10.800 --> 00:10:16.399
the art in your place make small adjustments if something you know could

00:10:14.560 --> 00:10:21.839
stand to be shifted to the left or adjust it a bit and this is really cool

00:10:19.360 --> 00:10:26.240
they've got over 15 000 artists who have contributed to over a quarter million

00:10:24.240 --> 00:10:29.760
different designs for each disc plate sold they will plant 10 trees they offer

00:10:28.079 --> 00:10:34.720
hassle-free returns they're pre-gift wrapped and they've actually partnered

00:10:31.760 --> 00:10:40.640
with cyberpunk 2077 to do a collection of cyberpunk themed artwork so go check

00:10:37.040 --> 00:10:42.320
it out and use code LTT to save 15 at

00:10:40.640 --> 00:10:45.600
the link in the video description so thanks for watching guys i hope you're

00:10:43.680 --> 00:10:48.800
as excited about the LTT edition coolers as we are if you're looking for another

00:10:47.040 --> 00:10:53.600
video to watch maybe check out the one where we actually compared the raw

00:10:50.720 --> 00:10:57.519
versions against water coolers with some pretty surprising results
