I don't know what's worse being the sort

of madman who specializes in voiding

your customers warranties or enabling

his Reckless Behavior the way that

noctua has done here this small plastic

spacer kit for their iconic Brown

coolers is not only 100 trust me bro

guaranteed to get your RMA rejected by

AMD but it also increases the chance

that something will go wrong I mean who

in their right mind would take a cooler

this size and bolt it directly to the

fragile dies that live under amd's

protective heat spreader

20 20 degrees 20 degrees look

that's impossible

impossible to explain until I finish

this segue to our sponsor Mexico whether

you're in need of webcams or accessories

for your VR device Mexico has a great

selection of products to choose from you

can learn more about them at the link in

if it was anyone else I'm not even sure

if I would believe this but after noctua

explained it the whole thing kind of

makes sense and it starts with the

creatively named noctua NM amv15 offset

am5 mounting bars you see the thing is

when AMD designed their am5 CPUs they

put the i o die in the middle and they

put the actual compute dies the ccds

down at the bottom of the IHS this puts

the hot spots of ryzen 7000 CPUs in a

very unconventional place and you can

see in noctua's illustration here how

this hurts the performance of a typical

cooler by having the hot spot down here

you can see we are over utilizing the

heat pipes on this side and under

utilizing the ones over here

that's where the offset bar comes into

play watch this by simply Shifting the

mounting mechanism seven millimeters

downward knock to assess they can drop

the temperature on your CPU by up to

three degrees this is because of two

effects first it concentrates the

pressure over those heat generating dies

improving thermal transfer and second it

means more effective heat distribution

throughout the base of the cooler so

you're making better use of all of your

heat pipes rather than over saturating

some and under utilizing others these

results are really impressive and

reinforce what we found in water cooling

Through the Ages where we saw that from

generation to generation the performance

improvements were less about actually

just building a better water block and

more about tuning the water block better

for modern processors so while ryzen

3000 and 5000 can benefit from this

offset Mount it's not to the same degree

pun intended as ryzen 7000 because those

ones have much thinner ihs's we'll be

talking about that in a second in

typical noctua fashion it'll be

available affordably for all their

desktop class coolers going back to

2005. but Linus you might say up to

three degrees is not almost 20 degrees

what's the deal with the rest of that

that is where this comes in these small

plastic spacers allow noctua coolers to

be mounted to d-litted CPUs and they're

the result of a collaboration with their

Bauer I mean it looks like the simplest

thing in the world a little piece of

plastic how could that drop you 15

degrees except

the devil's in the details look how

thick this is ah so I haven't played

around with delighted ryzen 7000 yet but

it seems that to maintain cooler

compatibility with the lower profile LGA

socket compared to their last generation

pin CPUs AMD made the IHS much thicker

which is contributing to some of the

thermal challenges that users are seeing

the solution

well if you hate having a warranty you

can do this

step one get your hands on a d-litted

ryzen 7000 series processor given they

developed the products collaboratively

noctua recommends the one from Roman

sold under the thermal Grizzly brand

they've been doing a lot of that collab

sort of stuff lately step two install a

direct die mounting frame like this one

again from thermal Grizzly this isn't

strictly necessary but it dramatically

reduces the risk of accidentally

cracking one of these delicate dies as

you're tightening down your cooler I

wouldn't even consider mounting a cooler

direct eye these days without one of

these frames next you're going to need

some liquid metal thermal compound okay

you don't actually need it but the issue

is that the benefit of this modification

with traditional thermal paste is very

low only about two to four degrees

this is because even though amd's IHS is

too thick at least it's soldered so it's

pretty fast at moving heat from the

hottest parts of the dyes I mean it's

right in the name right it's a heat

spreader so if we use a traditional

thermal compound right on these dies it

can be somewhat overwhelmed by the

concentration of these hot spots heat

flux density is the term that noctua

used but for all but the most technical

of our viewers that's unlikely to mean

anything so finally you'll need knock to

his offset Mount that I showed you guys

before okay you don't need it but if

you're going to avoid your warranty why

settle for 10 to 17 degrees of

improvement when you can have anywhere

from 12 to 19. that is the cumulative

benefit of all of these little changes

though now that your warranty is void

there are a couple of more things to

consider die cracking that's less of a

concern thanks to the contact frame but

liquid metal on any one of these little

surface mount components would be a big

problem so I would suggest some nail

polish or conformal coating or some

protective covering for the ones that

aren't already covered and here's the

coolest part noctua isn't even forcing

you to buy this spacer if you get your

direct eye contact frame and all this

stuff from other companies they will

make literally nothing providing you the

STL files of these spacers on

printables.com but they're doing it

anyway then all you need to do is Source

slightly longer screws and they're going

to have the information about which

screws you'll need on the printables

page again this works with the vast

majority of Knoxville coolers since 2005

and is launching at the end of July but

that doesn't mean that all cooling

Innovation is down to changing the

position and avoiding your CPU warranty

meet the next gen nhd15 it's got a

whopping eight heat pipes now compared

to six on the original and that's just

the beginning the heat pipes are

optimized for better performance you

know optimizing wall thickness Wick

structure all that kind of stuff but the

big one is this fan it's finally here

after what is this eight long years of

product development their new 140

millimeter fan and thanks to its

incredible performance giving it up to

three degrees better performance

compared to their old one on a radiator

they were able to increase the surface

area of the fin stack here by 20 meaning

that this should be good for anywhere in

the neighborhood of about three to four

degrees of improvement over the already

legendary NHD 15. now of course that's

on a 300 watt heat load so you better be

running an Intel CPU got him which is

why noctua actually doesn't recommend

buying this if you have a 65 watt CPU

what they would recommend is that I do
