00:00:00.160 --> 00:00:07.480
I don't know what's worse being the sort of madman who specializes in voiding

00:00:04.720 --> 00:00:13.120
your customer's warranties or enabling his Reckless Behavior the way that

00:00:09.400 --> 00:00:14.879
Noctua has done here this small plastic

00:00:13.120 --> 00:00:21.800
spacer kit for their iconic Brown coolers is not only 100% trust me bro

00:00:19.160 --> 00:00:27.240
guaranteed to get your RMA rejected by AMD but it also increases the chance

00:00:25.160 --> 00:00:33.280
that something will go wrong I mean who in their right mind would take a cooler

00:00:30.119 --> 00:00:35.840
this size and bolt it directly to the

00:00:33.280 --> 00:00:44.160
fragile dyes that live under AMD's protective heat spreader that 20° 20 20°

00:00:41.239 --> 00:00:49.559
20° low that's impossible impossible to explain until I

00:00:47.039 --> 00:00:54.359
finished this segue to our sponsor nexigo whether you're in need of webcams

00:00:51.800 --> 00:00:57.600
or accessories for your VR device nexo has a great selection of products to

00:00:55.920 --> 00:01:04.879
choose from you can learn more about them at the link in the video description

00:01:04.879 --> 00:01:11.320
if it was anyone else I'm not even sure if I would believe this but after Noctua

00:01:09.759 --> 00:01:18.240
explained it the whole thing kind of makes sense and it starts with the

00:01:13.920 --> 00:01:21.439
creatively named Noctua NM am15 offset

00:01:18.240 --> 00:01:24.920
am5 mounting bars you see the thing is

00:01:21.439 --> 00:01:27.320
when AMD designed their am5 CPUs they

00:01:24.920 --> 00:01:34.200
put the io die in the middle and they put the actual compute dieses the CC s

00:01:30.720 --> 00:01:37.560
down at the bottom of the IHS this puts

00:01:34.200 --> 00:01:40.439
the hotpots of ryzen 7000 CPUs in a very

00:01:37.560 --> 00:01:44.799
unconventional place and you can see in noct towa's illustration here how this

00:01:42.759 --> 00:01:50.119
hurts the performance of a typical cooler by having the hot spot down here

00:01:47.600 --> 00:01:55.159
you can see we are over utilizing the heat pipes on this side and

00:01:52.159 --> 00:01:57.320
underutilizing the ones over here that's

00:01:55.159 --> 00:02:03.200
where the offset bar comes into play watch this by simply Shifting the

00:01:59.439 --> 00:02:04.759
mounting mechanism 7 mm downward Noctua

00:02:03.200 --> 00:02:12.239
says they can drop the temperature on your CPU by up to 3° this is because of

00:02:08.959 --> 00:02:14.760
two effects first it concentrates the

00:02:12.239 --> 00:02:20.560
pressure over those heat generating dyes improving thermal transfer and second it

00:02:18.080 --> 00:02:25.080
means more effective heat distribution throughout the base of the cooler so

00:02:22.480 --> 00:02:29.920
you're making better use of all of your heat pipes rather than oversaturating

00:02:27.200 --> 00:02:33.760
some and underutilizing others these are results are really impressive and

00:02:31.560 --> 00:02:38.560
reinforce what we found in water cooling Through the Ages where we saw that from

00:02:36.000 --> 00:02:43.239
generation to generation the performance improvements were less about actually

00:02:40.920 --> 00:02:48.440
just building a better water block and more about tuning the water block better

00:02:45.879 --> 00:02:54.840
for modern processors so while ryzen 3000 and 5000 can benefit from this

00:02:51.360 --> 00:02:58.239
offset Mount it's not to the same degree

00:02:54.840 --> 00:03:01.480
pun intended as ryzen 7000 because those

00:02:58.239 --> 00:03:03.480
ones have much thinner IHSS we'll be

00:03:01.480 --> 00:03:07.680
talking about that in a second in typical nocta fashion it'll be available

00:03:05.640 --> 00:03:16.280
affordably for all their desktop class coolers going back to 2005 but minus you

00:03:11.760 --> 00:03:18.000
might say up to 3° is not almost 20°

00:03:16.280 --> 00:03:24.959
what's the deal with the rest of that that is where this comes in these

00:03:22.400 --> 00:03:28.920
small plastic spacers allow noct TOA coolers to be mounted to delited CPUs

00:03:27.799 --> 00:03:32.439
and they're the result of a collaboration with their Bower I mean it

00:03:30.959 --> 00:03:36.920
looks like the simplest thing in the world a little piece of plastic how

00:03:34.720 --> 00:03:41.400
could that drop you 15°

00:03:38.439 --> 00:03:49.000
except the devil's in the details look how thick this is ah so I haven't played

00:03:45.319 --> 00:03:51.360
around with deleted ryzen 7000 yet but

00:03:49.000 --> 00:03:57.000
it seems that to maintain cooler compatibility with the lower profile LGA

00:03:54.560 --> 00:04:03.079
socket compared to their last generation pin CPUs AMD made the I CH much thicker

00:04:01.640 --> 00:04:09.519
which is contributing to some of the thermal challenges that users are seeing

00:04:06.159 --> 00:04:13.519
the solution well if you hate having a

00:04:09.519 --> 00:04:16.359
warranty you can do this step one get

00:04:13.519 --> 00:04:19.959
your hands on a delited ryzen 7,000 series processor given they developed

00:04:18.239 --> 00:04:23.600
the products collaboratively nocta recommends the one from Roman sold under

00:04:21.720 --> 00:04:28.280
the thermal Grizzly brand they've been doing a lot of that collab sort of stuff

00:04:25.240 --> 00:04:30.320
lately step two install a direct die

00:04:28.280 --> 00:04:36.600
mounting frame like this one again from thermal Grizzly this isn't strictly

00:04:33.560 --> 00:04:38.880
necessary but it dramatically reduces

00:04:36.600 --> 00:04:42.639
the risk of accidentally cracking one of these delicate dieses as you're

00:04:40.600 --> 00:04:46.800
tightening down your cooler I wouldn't even consider mounting a cooler direct

00:04:45.120 --> 00:04:51.880
die these days without one of these frames next you're going to need some

00:04:49.240 --> 00:04:56.440
liquid metal thermal compound okay you don't actually need it but the issue is

00:04:54.199 --> 00:05:02.759
that the benefit of this modification with traditional thermal paste is very

00:04:59.000 --> 00:05:07.080
low only about 2 to 4° this is because

00:05:02.759 --> 00:05:09.720
even though AMD's IHS is too thick at

00:05:07.080 --> 00:05:14.320
least it's soldered so it's pretty fast at moving heat from the hottest parts of

00:05:12.199 --> 00:05:20.080
the dyes I mean it's right in the name right it's a heat spreader so if we use

00:05:17.120 --> 00:05:24.240
a traditional thermal compound right on these dyes it can be somewhat

00:05:22.000 --> 00:05:30.280
overwhelmed by the concentration of these hotpots um heat flux density is

00:05:27.759 --> 00:05:34.120
the term that Noctua used but for all but the most technical of our viewers

00:05:31.800 --> 00:05:38.240
that's unlikely to mean anything so finally you'll need noct to his offset

00:05:35.960 --> 00:05:43.360
Mount that I showed you guys before okay you don't need it but if you're going to

00:05:40.360 --> 00:05:46.039
avoid your warranty why settle for 10 to

00:05:43.360 --> 00:05:52.160
17° of improvement when you can have anywhere from 12 to 19 that is the

00:05:49.520 --> 00:05:55.720
cumulative benefit of all of these little

00:05:53.039 --> 00:06:00.600
changes though now that your warranty is voided there are a couple of more things

00:05:57.360 --> 00:06:03.039
to consider die cracking that's less of

00:06:00.600 --> 00:06:08.960
a concern thanks to the contact frame but liquid metal on any one of these

00:06:06.800 --> 00:06:14.000
little surface mount components would be a big problem so I would suggest some

00:06:11.319 --> 00:06:18.160
nail polish or conformal coating or some protective covering for the ones that

00:06:15.680 --> 00:06:23.800
aren't already covered and here's the coolest part Noctua isn't even forcing

00:06:21.080 --> 00:06:27.919
you to buy this spacer if you get your direct eye contact frame and all this

00:06:25.479 --> 00:06:32.599
stuff from other companies they will make literally nothing providing you the

00:06:30.560 --> 00:06:37.680
STL files of these spacers on printable.com but they're doing it

00:06:35.160 --> 00:06:40.440
anyway then all you need to do is Source slightly longer screws and they're going

00:06:39.240 --> 00:06:47.440
to have the information about which screws you'll need on the printables page again this works with the vast

00:06:44.560 --> 00:06:51.199
majority of Noctua coolers since 2005 and is launching at the end of July but

00:06:49.759 --> 00:06:56.440
that doesn't mean that all cooling Innovation is down to changing the

00:06:53.440 --> 00:06:59.639
position and voiding your CPU warranty

00:06:56.440 --> 00:07:02.440
meet the NextGen nhd15

00:06:59.639 --> 00:07:07.319
it's got a whopping eight heat pipes now compared to six on the original and

00:07:05.360 --> 00:07:11.360
that's just the beginning the heat pipes are optimized for better performance you

00:07:09.440 --> 00:07:17.759
know optimizing wall thickness Wick structure all that kind of stuff but the

00:07:13.720 --> 00:07:21.360
big one is this fan it's finally here

00:07:17.759 --> 00:07:25.759
after what is this eight long years of

00:07:21.360 --> 00:07:28.479
product development their new 140 mm fan

00:07:25.759 --> 00:07:33.400
and thanks to its incredible performance giving it up to 3° better performance

00:07:31.120 --> 00:07:38.280
compared to their old one on a radiator they were able to increase the surface

00:07:35.479 --> 00:07:44.199
area of the fin stack here by 20% meaning that this should be good for

00:07:41.240 --> 00:07:48.400
anywhere in the neighborhood of about 3 to 4° of improvement over the already

00:07:47.080 --> 00:07:54.800
legendary nhd15 now of course that's on a 300 watt

00:07:52.720 --> 00:07:59.080
heat load so you better be running an Intel

00:07:55.879 --> 00:08:00.759
CPU got him which is why Noctua actually

00:07:59.080 --> 00:08:06.840
doesn't recommend buying this if you have a 65 wat CPU what they would

00:08:04.080 --> 00:08:10.159
recommend is that I do this segue to our sponsor if you enjoyed this video what

00:08:08.759 --> 00:08:16.440
the hey why don't you go check out our one on the development of the screwdriver which uh this actually

00:08:14.319 --> 00:08:21.199
reminds me a lot of because For Better or For Worse I take a ton of inspiration

00:08:18.840 --> 00:08:27.080
from these guys only shipping things once they are absolutely ready
