Transcripts

so LT or lonus Tech tips or lonus Media

Group has put out PTM

7950 I think they've done one video on

this stuff before I've touched on this

stuff many times I've done it in many

videos for handhelds and I promote it on

lots of different devices so I have a

lot of experience with PTM 7950 PTM 7950

is a phase change material it's a

thermal solution that you can put on a

heat sink for example put your cooler on

it for a CPU or a GPU and in theory just

like a thermal

paste it's going to help transfer heat

off of the chip into the cooling unit

and then basically get that heat out of

the system we have a few different

options out there we have thermal paste

obviously we have thermal pads uh

there's like different types of pads you

can buy there's liquid metal and then of

course there's PTM 7950 paste comes as

generally as a liquid type material kind

of like a paste you put it on there and

it just stays as a paste basically until

it dries out essentially and it gets the

heat out and it's kind of the de facto

it works but it you know there's better

stuff out there uh there's like pads in

that typically like this is for like

vrms and that but you can get them for

CPUs as well and uh they apparently work

okay but they're not fantastic they're

just kind of easy of course then there's

liquid metal which liquid metal probably

is the best solution right now but

however it does carry risks you can it's

conductive so you can fry your system

PTM 7950 I've covered many times on my

channel uh basically what is a phase

change material so it comes kind of like

a pad of sorts but it's also a lot more

liquid kind of you can see it there it's

between two

plastic sheets there and inside is

basically a past like material it's a

little bit thicker than paste you put it

onto your CPU or your GPU then you

basically do a bunch of heat Cycles cold

heat cold heat cold heat get those

temperatures up and over time what this

is going to do is it's going to actually

turn into a solid material and that

solid material has much more

conductivity than thermal paste in

theory so basically what's going to

happen is it's going to be more

effective than thermal paste should have

really good longevity as well so I've

been buying my PTM you can get it on a

site called e by7 that's where I've been

buying it if you go on the legion

Discord I think they recommend it there

but that's where I recommend it and it's

Honeywell PTM 7950 you can see that

there and it works it works amazingly

well much better than paste and it

appears to be authentic anytime I've

ordered it from them uh that's what that

is there this giant sheet is from them

as well but you have to order it from

China it's imported um and it takes a

little bit of time and it's just not the

most transparent selection I've had no

issues with it I've ordered it many

times but uh for some people they may

not be comfortable doing that so uh LT

has their I guess solution to that and

they're just basically selling it

themselves I'm sure they're bringing it

in it could even be from that company

I'm not sure like the reseller bringing

it in of course it does come at a huge

price premium but they do sell and it's

easy you just go to the LT website you

give them to your American

dollars which I guess they then convert

into Canadian dollars and ship from

Canada and then ship it back to me in

Canada so I'm giving them Canadian

dollars which are converted into

American then it goes back into Canadian

dollars to them and then they ship me

the Canadian product in can Canada

figure that out uh I don't know why they

don't just offer Canadian probably

because American dollars are worth more

and it's a business idea uh but anyways

this is going to be for a lot of people

an easier way noctua I can just throw

some noctua or like Arctic Silver um I

might because people don't necessarily

know what tf8 is necessarily thermore I

might just use the nocta stuff the

nth1 just cuz people know what it is and

they're like comfortable with it so I

might use that uh so I'm going to do a

test with thermal paste I'm going to do

a test with the uh honey well stuff that

I know is honey well I'm going to do a

test also with

the Linus stuff here but realistically

if the line is stuff so my results here

that I expect to be is the paste works

fine whatever then I expect that the

actual uh PTM is going to be much better

significantly better it should result in

lower temperatures potentially better

scores uh like if we're doing like Cent

or something like that you should get

better scores uh but generally speaking

just better temperatures overall so I

expect this stuff to work fantastic

because I pretty much know that it does

uh however I haven't used it on that

chip specifically and then I expect

hopefully the line of stuff to be equal

so what would happen in an ideal

scenario here is the stuff that I

imported that I know is authentic

Honeywell PTM 7950 is going to work just

as good as the lionist stuff which then

speaks good to the lonus stuff for LTT

this stuff performs as good or better

I'm just hoping for as good as the

official honey well and if it performs

as well as the honey well I can see that

they've carved out a very important

market for people who don't want to

necessarily import this stuff from a

random site overseas okay here's a look

at the internal cooling system on the

laptop again RTX 4090 and 13950 HX so

very hot CPU very hot GPU has pretty

good cooling two fan setup nice thick

fans there heat pipe heat pipe with a

vapor chamber so overall it it actually

is a very uh well cooled system overall

it doesn't run at full wattage though

the GPU is not going to be you know like

170 watt variant but again it's still

hot components here so that's what that

looks like I'm going to take these off

here and you can see what it looks like

inside and then we'll basically show you

then I'm going to basically show you

what it is like to apply PTM 7950 it's

different than thermal paste you know

just spread it on it's a little bit

different but let's take this off and

have a look okay and here's the thermal

paste application you can see there it's

just a nice spread you can see the

difference in thermal paste it's just

kind of like a like it's paste right uh

and when it stays in until it dries out

like which is a bad thing on thermal

past you don't want it to dry out it'll

stay with this type of semi kind of

thick consistency and then eventually

it'll dry out and become less effective

but realistically this is kind of how

the paste should stay like basically as

a paste with the PTM obviously it's

going to harden into a hard material

like a solid so that's the application

there pretty good I'll just make sure

that I didn't miss anything let's open

this up here and I'll show you how to do

it so what you do basically is you cut

it so I need to get my little slice see

this is a huge a massive sheet of the

stuff here so uh basically what you do

is you cut it to the shape of your uh

chips you don't really want to go over

much it's not conductive so it's not

going to cause damage but you don't want

to go just like way over uh for one it's

pretty expensive but also it just makes

it a bit of a pain when you're peeling

it off so the way I do it is I kind of

get it just slightly over make a little

Mark there and then I'll make a little

Mark there the actual plastic on this is

a different m material than the official

honey well or so I can tell official

honey well uh it can be a little bit of

a pain now because you have to actually

peel it off at least the other stuff is

I don't know if this is easier the

plastic on the outside appears to be a

different

material so you basically peel it off

like that like that there of course when

it gets on your hands it never comes off

doesn't exactly stain it it just like

literally gets into your clothing I'll

cut a little piece piece of it off later

and we'll do a comparison Head to Head

put it on like that uh you want to give

it some pressure so it sticks to the

chip you don't have to like press super

hard just a little bit of pressure uh

and then you peel it off which can be

this is the hard part because you don't

want to peel it right back off of the

actual chip that a terrible this is why

I go a little bit over and that's the

side that I pull from and then you have

to be careful because it will be prone

to basically peeling off of the

chip okay not bad that's actually a

pretty good application there yeah so

other than the blue hue on the LTT

plastic like physically the plastic you

can see there it's got a blue hue to it

can't really probably see on camera the

actual little pad is the same color

appears to

be

and this is the honey

well again it's a different type plastic

underneath that's the LTT they do feel

the same and the thickness to my eye

it's very very very thin

right luckily I'm

nearsighted so I have good up close

Vision but I do not have the best far

Vision they seem to be the same to be

honest okay and there we go it's applied

nice and flat goes over a little bit

doesn't matter it's not uh it's not

thermally conductive so it doesn't

matter that it goes over slightly you

don't really want to touch it when you

put the uh actual thermal solution back

on you don't want to move it around a

lot because it's going to mess it up

basically you want to put your thermal

back on just basically set it on push it

down screw it in you don't want to move

it around it's not like a past that can

squeeze out or anything like that so you

really want to kind of oneshot this on

you want to tear it and mess it up uh so

there you go that's how it's going to

look there and we'll put this back

together and we'll start uh cooking it

and I'll show you kind of the process of

that as well this is the LTT stuff so

when you first apply the PTM 7950 you

may actually find your benchmark scores

go down what you need to do is

essentially turn that liquidlike

material into a solid and I call that

basically cooking the PTM so what you do

is you're going to run a bunch of

benchmarks what I typically do if it's

just you know an APU you can just run C

bench if it's a CPU and GPU system what

you want to do is basically slam it with

a bunch of heat so I loaded up cin bench

a bit and also Boulder's Gate and just

basically let it sit there at full load

getting that PTM nice and hot so I do a

cycle of that for about 10 minutes then

I cool it down let the game kind of just

shut off let the chip cool down then I

do it again I heat it up cool it down

heat it up cool it down I do that

usually five six times maybe seven times

and then typically what I do is I just

play a game for a little while like

maybe half an hour or something like

that then when I'm done I shut down the

system and I leave it overnight when I

come back in the morning typically what

happens is those scores are going to go

way up because the PTM has turned into a

more solid material and you may find

that slowly over the next few days as

well you might find that you're getting

a little bit better results overall as

that PTM turns liquid into a solid okay

so now let's look at some results here

so first runs I did cinch I did two runs

of cin bench logged it in Hardware info

you can see here that the noctua pace

the average temperature throughout run

was about 100° on the two ptms it was

considerably lower the honey well was

93.8 so basically 94 and the Linus was

94.1 so basically 94 so interchangeable

and a considerable drop from the average

on the nocta paste you can see here that

the average that the actual temperature

max is a little bit lower as well 100

105 dropped down about 100 or so so a

little bit of a temperature drop on the

max basically you're getting Peaks here

and that it's throttling and I can say

that because the average Watts on the

past is only about 80 where it's 93 on

the PTM and 100 on the Linus so I mean

regardless of which Pace you use and

regardless of which PTM you use it looks

like the PTM is going to have a profound

effect on cooling where the CPU is able

to just basically boost more and run at

a higher wattage which would give you

higher scores obviously because you're

basically getting higher Watts overall

because of lower temperatures so you can

see here that the pace is having a

really hard time of keeping the CPU cool

which is then just resulting in

throttling and you can also see that

here in the clock so

2685 average clocks on the nocta pace

versus 29 and 3,000 on the lineus PTM so

these ptms are making a big difference

on clocks and they're pretty close to

one another uh it could just come down

to you know how good of a job I did

applying them and that so I would call

these relatively interchangeable

although the average watts is quite nice

there a little bit more on the line of

stuff there uh noise levels were a

little bit louder on the uh paste but

not much it basically was just

throttling rather than the fan getting

noisier it's probably Peak fan

realistically on this laptop so it just

went up and then it just throttled down

on the pace because it wasn't able to

keep it

cool and that did result in higher

scores so the first run on the paste and

the second run on the pace and I gave

these a few minutes to cool down between

around 20 21,000 22,000 so it's okay but

you can see a pretty big jump there when

we went to the PTM we went to 24.5 and

around 24.3 so big jump in performance

there overall and the line of stuff was

around the same the first run was

slightly higher you can see here uh and

then the second run was more normal so

basically the same as that so relatively

interchangeable between these two ptms

here showing that the line of stuff is

doing the same as the honeywall that I

had to import which is good and both of

them are making a huge difference over

standard pace and this is good Pace this

knct door paste then I did some Boulders

gate I just left the game to run for

about 10 minutes or so and I just wanted

to compare the paste to the uh PTM

because I mean obviously the honey well

is doing the same stuff as the line of

stuff here so you can see here that the

average temperature on the CPU was 81 on

the pace almost 82 and then it was about

76 on the uh line of stuff so that's

going to be about 6° cooler on the line

of stuff if not 7 degre cooler so that's

good that's what you'd expect uh

temperature max is the same so it's just

throttling basically average watts are

also higher on the line of stuff so it's

running cooler despite the fact that it

has more watts going in interesting The

Clocks Were averaging higher on the uh

uh paste but it didn't really make a big

difference you'll see the FPS are

basically the same uh GPU now the

average watts are also the same 130 on

the knct pace 130 on the line of stuff

now one thing is this is not the highest

watt version of this system it's you

know has highend components 13950 HX RTX

490 but they're both set to a relatively

low temperature threshold uh you know

this and watt threshold so you can see

here you know this GPU is actually not

really ready to even go that high let

alone you supposed to be about 115 Watts

let alone 130 watt so that's definitely

just a power Peak on this system here if

you had a hotter system a thicker system

something like you know a Lenovo Legion

or an MSI larger laptop or an Asus

larger laptop that was allowing more

watts to go into the GPU let's say 150

watts 160 Watts 170 Watts you'd probably

see even a more pronounced effect

between the two of them here but I just

wanted to clear that up slightly that

this is just basically a wattage

limitation here and you would see

probably increasing the Watts even more

even a more pronounced effect GP

temperature was higher on the paste here

lower on the line of stuff here remember

Junction temperature was higher on the

paste lower on the line of stuff here

hotspot temperature was higher on the on

the paste lower on the PTM GPU clocks

were close to one another uh memory

clocks were close to one another and

video clocks were relatively close to

one another and uh basically FPS was

interchangeable so what you're basically

seeing here is that the PTM works so PTM

in general will see a fairly profound

effect especially on CPU uh the GPU here

is just not the hottest iteration of a

4090 uh but on the CPU here you can

really notice that PTM in general is

going to lower CPU temperatures which

allows more watts to go into it which

allows a better score okay so what do I

think of the Linus paste or Linus PTM uh

it works it seems to be authentic when

compared to the stuff that I imported

the you know most likely authentic PTM

7950 honey well that I imported overseas

and I've been using on and off for years

basically and a lot of people have

bought off these same buyers uh I mean

it seems to be performing identically

basically potentially better but it's

hard to say you know it's probably just

margin of user a how well I applied it

in the first place but it performs at

least as well as the stuff that I'm

bringing in from overseas which is

fantastic because PTM 7950 if you've

watched any my videos and I've shown it

in many different devices it works

considerably better than thermal paste

even really good thermal paste I have

different types of pastes here you can

see all these here and paste can be good

and it's easy to use it's really really

cheap but when it comes down to it the

PTM stuff works better I especially find

this true on devices that have limited

cooling so laptops handheld devices

because there's only so much heat sink

that you can get in there only so much

fan you can get in there you know if you

have some desktop with a giant massive

fan on it and 17 heat pipes coming off

of it and liquid cooling and I mean it's

probably still going to be fine with

past realistically Because the actual

cooling solution is massive however when

you have limited space you're looking at

something like a laptop something like a

handheld PTM 7950 does work better than

paste you're going to basically get

lower temperatures which is going to

potentially reduce fan noise it's going

to reduce wear and tear on those devices

and most importantly by having lower

temperatures you may experience higher

wattages going into those gpus into

those CPUs which gives better

performance that's especially true if

you have thinner chassis like say you

know if you're looking at a thin and

light laptop with a lot of beefed up

components inside you're going to be

able to get that heat out a little bit

better on those devices that are a

little bit thermally constrained or if

you just have some Behemoth that has you

know an I9 processor that's just going

to be an absolute hot box in there and

then 4090 and unlike my 4090 that you

know really just is supposed to be at

about 115 but boost up to 130 maybe your

4090 is at 150 and boost up to 170 or

something like that that's a lot more

Heat going to that GPU and a lot more

overhead for watts and therefore for

performance so if you're able to keep

that GPU cool and that CPU cool you're

going to get better performance on those

parts you're going to potentially get

less fan noise which is good because

then it's less annoying you're also

going to potentially reduce wear and

tear on those GPU and CPU if you're

putting money into your device and you

want to be getting the best performance

out of it and you're comfortable taking

off that Cooling solution and putting on

something like this and it's not in your

country every country is different it's

not going to avoid your warranty here in

Canada it will not avoid the warranty

but in some countries it could so just

be aware of that PTM 7950 Works amazing

I do also recommend I mean if you can

pick this stuff up so easily now from LT

from lonus uh I mean why not throw it in

your desktop I probably will honestly

it's just so easy to get and you get

nice big sheets there it will outperform

a paste in a desktop as well it's just

that I typically find that's more

pronounced in smaller devices but I mean

if I can get Giant sheets of this stuff

like that for I mean I wouldn't call it

cheap right this stuff is not cheap by

any means uh but for the number of

applications you get out of it right

this stuff lasts for a long time unlike

paste so I mean put in your bunch of CPU

dieses in here unless you're like an

like a benchmarker or something you're

swapping out devices all the time you

know something like this could last you

for years just one of them I of course

picked up three of them because I just

wanted to get the free shipping but I

mean you could buy some other stuff off

of them whatever uh but realistically I

mean just one of these is going to last

me for quite a long time I I do laptop

reviews and benchmarks so I'm going to

be swapping this stuff a lot so for me

you know it's not going to last that

long but for you something like this

would actually last a really long time

realistically so yeah I mean if you're

looking to pick this stuff up it seems

to be good uh so good job to lionist and

team I mean they're not making this

stuff but they're bringing it in they

obviously found a source for this stuff

that is legit uh the price I would

consider Fair considering it's coming

from you know North America they're

importing it from whatever country

getting it in here packaging it up

wherever they package it up uh it's in

North America and you know this stuff's

a little bit hard to buy overseas and so

now we have access to it and it's going

to last you for a long time I think it's

pretty fair and the most important thing

is it works just as well if not slightly

better but I would say at least as well

as the authentic honey well PTM 7950 and

that means that it's going to work a lot

better than thermal paste so yeah good

job guys it works well and it seems to

be authentic that's the test
