an we make DIY Thermal Paste?? #Helpful Post

ot totally sure how many people

would recommend this but uh all of us PC

building tech dudes already know about

thermal paste okay aka the hot stuff aka

the gray goo aka Grammys old sandwich

spread what but what if you're outta

thermal paste yeah you could just go

order more picks them up from NCI X or

you could make your own

- actually got an email from a fan

suggesting we do this so in this video

we are going back to chemistry class and

finding out whether any of these

materials can work as a thermal paste

substitute because Linus isn't here and

he can't stop us but I do have Alex here

to make sure that I don't blow up this

PC with Nutella because that that's a

real possibility what

the hex gears impulse mechanical

keyboard has RGB lighting a variety of

different key switches and IP 56 water

resistance so it can survive some of

your worst spills use offer code LTT to

save $10 at the link below as Alex could

tell you but I will instead there's two

main things fuck guys I'm not Linus till

we get there sadly okay so the main

purpose of thermal paste is to assist

the heat transfer between the CPU and

the heatsink when you put them together

because you put them together but

there's still a little bit of gaps in

between so what do we need thermal paste

to do what are the two main

qualifications we're looking for so I

guess the first one is that needs to be

really easily spreadable so like you

have all this little dips and stuff and

you want to just fill those in you don't

want to be creating like a layer between

your CPU and your heatsink right and the

other thing is that it has to be really

good thermally conductive so you don't

have just like a bunch of resistance

between the two hmm you want that heat

to be transferred yeah okay so with

those qualifications there are a large

number of materials that we could

potentially use with varying

efficiencies so what do we have here

okay so some of you might be familiar

with this toothpaste a lot of people

have tried it and we're not gonna try it

by itself today because it's been tried

a lot but it's actually a surprisingly

effective substitute the problem is that

it's got fluoride in it and that means

it's slightly corrosive and it also

tends to dry out very easily so what

we're gonna mix it with thanks to some

tips on the Internet is petroleum jelly

aka Vaseline but this is the no-name

brand you can really bad stuff why is

bad it's chunky oh that's true

but if we mix it together I don't know I

mean this is a smooth type of toothpaste

because the main thing when you're using

toothpaste you don't want the the gritty

kind with like the little beads in it or

whatever I'll just do it we just do it

yeah I wanted to do it okay you could oh

dear yes maybe

I feel like that's slightly dangerous

what you're a monster Alex what CPU is

this also

that's a 79 80 XE so maybe we don't want

to get toothpaste a like a $2,000

process you're supposed to rein me in

I'm not supposed to rein you in what are

we doing here ah I don't know it seems

to be working okay like I don't think

it's the way that you thought that we

are true well I think we're about good

like okay yeah you want to try it like

that yep the wrong way all right well

you've made your bed and now we're gonna

lie in it I guess so I'm guessing that

you've already done the testing I ran a

baseline with real thermal paste and I

also ran it

bareback as they say did you find a

board that doesn't have a power button

on it

no it has a power button ready whoa it's

on it works yes so we just got a boot it

up and then run I to 60 for a little bit

and stress test it and see whether the

computer will explode that's how we know

right yeah yeah all right I had a 64 um

where do we have the weight it should

come up automatically because I'm a

prime a programmer I'm a big big tech

hacker look at that oh jeez Oh fancy

see that's what the toothpaste does oh

that's pretty good

like 20 degrees idling very nice

what was our baseline head over to

documents they're back in baseline so

baseline we're looking at a max of about

65 degrees package go up to 70 hottest

for 65 bareback we are looking at

hundred and four degrees yep that's not

good yeah when I did the bareback it

just shot right up it past a hundred so

so let's see here toothpaste and

Vaseline

looking actually not bad with CPU

package is already at 68 hottest core

okay so we're at 65 already so we're not

beating thermal paste that is for sure

things go real slow in your stress test

in the CPU that's what I learned and

which I already know it's only like five

degrees over like actual thermal paste

those so it's a way better option than

just not having anything that's very

true so if you're like really in a bind

you're like I gotta get my old my dad's

old Dell from when I was a small child

up and running immediately right now not

bad not horrible one of them got up to

79 that's too hot

I wouldn't go outside if it was that hot

so that one was kind of a joke all right

guys but this next one actually might

work as a real substitute because what

we're using is silicon grease Thorne

Lube it's wet Oh ring Lube it's a ring

loop and that's not something dirty it's

just things that you use for o-rings

yeah yeah so we're actually combining

silicon grease with drum roll please

Diamond powder

cool I didn't even know that was a thing

but it is so we're basically using the

diamond as the thermal conductor and the

silicon grease as the medium for that

material we're not just throwing this on

okay we're gonna mix it properly this is

a science this is a science laboratory

and I won't stand for your nonsense so

before if you're gonna deal with diamond

powder at all guys we need masks alright

and I'm really glad that Alex brought

that up yeah let's do that I would have

remembered about the masks okay yeah

after you started coughing

so this is what 0 to 100

don't open it yet 0 to 1 micron diamond

powder I guess this is traditionally

used for like polishing mirrors no it's

25 carat 25 carat oh okay

so the ratio we're supposed to use is

around 60/40 whatever that means I'm

just gonna eyeball it them yep

papa Alex so is this kind of just like

making icy diamond like icy diamond has

diamonds in it right yeah and it kind of

looks like it - do you think we need

more grease in there yeah maybe a bit

should I be wearing gloves it's probably

got some icy diamond for comparison oh

wow that's dark yeah this is a lot

thicker than other thermal pastes

so how much did this diamond powder cost

for that package it was like 15 bucks or

something oh this is also a super weird

application well you're taking your mask

off yeah what are you doing the dust

isn't around anymore we're good oh no

science class is not in session anymore

well except for the science for doing

this yeah except for the except for this

yeah we do what we must because we can

that is a proverb and a half right there

all right so idle looking like 30

degrees that feels like it's higher than

what it was last time but uh the diamond

powder and the silicon grease is uh

there's a little bit more of a practical

alternative you're not just like trying

to get something up and running right

away you're like you know what screw the

system I'm making my own thermal paste

I'm growing my own tomatoes in my

backyard that's that's what that's who

this is for yeah but it's working really

bad this is like when you when you try

and make tomatoes in your backyard and

then you know the deers eat them and

yeah and it ends up that you weren't

even growing tomatoes the whole time

they were like you'll actually weed yeah

all right so this here is my idea I've

got some rapid tap you want to use rapid

tap instead of silicon grease yeah okay

well if the problem also could be that

our diamonds are just too big and we

need smaller ones

ever be too big did you imagine just

having a great big diamond I also don't

know if rapid tap is electrically

conductive it probably is so we

definitely will not want to be getting

this on anywhere that's not the CPU okay

I guess we're about good to go for this

thing cool for your your my Lou Beacon

culture this was not endorsed by my

internet sources so no guarantees that

it will perform as well as our homemade

diamond paste I think it's gonna be

better this is actually like how you

would use this normally you'd like

combine it with an oil and then spread

it out on like a surface plate and

polish something speaking of which do

you want to do that after I do what I'm

seeing 67 77 I think your diamond faces

like it's worse than toothpaste and

petroleum jelly by quite a bit yes good

so don't go up by in diamonds just use

your freaking toothpaste

you know diamonds are kind of useless

like they cost a lot and they don't

really do anything except look pretty I

thought this would be one functional

application bye see you later see you

later

I think mustard is going to destroy this

oh my gosh you know you put your faith

in something and then it just lets you

down yeah and then you go all the way

down hit rock bottom and try it mustard

there we go starting the test

I see 47 52 57 58 we're still living

better than the diamond at this point 63

so basically condiments are way better

than diamond powder well okay we just

had 74 but it's like this is usable this

is an 18 core processor you know what

this means we got to build a

liquid-cooled PC just using condiments

well it works so great with concrete so

yeah I think we can call that basically

a win for mustard all right well so it

seems like anything besides diamond

paste as far as last-minute things go

not the worst surprisingly okay let's

move on so the thing about Nutella it's

the only stuff here that I kind of want

to eat so that's actually not coming off

how do you get mustard off any nice soap

we've cooked the mustard on to the metal

now we're gonna now we're in a bit of a

pickle what okay well hold on hold on

hold on it's wet dude it's dripping yeah

exactly because we need to get it off

but what about this so let's just kind

of pack that around the CPU ah alex is

supposed to keep me in check for this

video I have find myself stress look if

we wreck this board it's your fault oh

that's fine I think it's all good it's

only like a little bit of water that's

around there now and it's basically all

gone so yes this is what we thought

would do better than mustard I'm not so

confident

anymore you know being a cameraman is

hard work I understand I here you go

David yeah yeah there you go

how's that that was weird

in a university while I was studying for

exams one time I just like downed a

whole bottle of Nutella much like I had

it there just like with the spoon and

then I'm threw up violently and I didn't

need Nutella for like six or so years

after that you do weird things

Nutella addiction is a scourge a skirt

it's no joke

let's see if Nutella is really gets

results that are just as nutty as it is

okay so we're looking already at 52

degrees up to 60 I see 63 65 71 okay

this is nothing he's good at custard so

I wasn't really joking when I said we

might blow up the PC with Nutella

no it might be worse than diamond paste

everything is terrible I guess sugar and

fat content isn't everything maybe we

should just put a frere roche just like

right in the middle there's the point

okay now actually I'm expecting this to

maybe do okay because it's 40% zinc

oxide is that good which is the main

ingredient in some thermal pastes and I

don't know why

zinc oxide would be helpful to baby bums

but it might be helpful to this baby bum

right here all right

okay

16900 not not worse than mustard mustard

we're one degree off from mustard though

I think that we might find out that

mustard is your best bet like mustard is

probably better than some budget thermal

pastes so this is officially worse than

mustard for like a few minutes for

diaper rash cream yeah true

it is diaper rash cream and it's not

gonna dry out we're only six degrees up

yeah six degrees isn't too bad I really

did not think any of this

Hey what is that you want to whoa that

right there is a lapping plate this is

so heavy

what are we gonna do with this oh let's

steal so take it right on top well what

like the whole point of thermal paste is

to fill in the gaps but what if there

were no gaps yeah much like should be

tender dates everywhere we are going to

just try and do it with no thermal paste

and I didn't say that quite right yeah

whenever I go on dates and they don't

have thermal paste man I'm just gone

yeah we need just a little bit of this

polishing compound polishing compound is

that like diamond powder

yeah diamond powder actually is a

polishing compound of sorts gonna just

throw some rapid tap in here

Kabam do a little stir yeah now we just

have to put it on lock and plate and go

him very rhythmic you're essentially

grinding down the surface of the

heatsink block yes so that it's smooth

as a baby's bottom

smooth air even if you want to get the

CPU uh-oh

so wait you're gonna drag the CPU across

that yep that's that's the plan I didn't

know that

adding Alex to this video would make it

more off the walls

Wow that's turning into just call for

now all of the protective coating is

just leaving so I'm going to need to

step up to a lower grip but higher

cutting power

I have never done CPU laughing before it

is a thing that lots of people do to

improve performance we aren't doing this

to improve performance but we're doing

it to prove that protection is for the

weak yeah people please don't have that

bigger takeaway here

I don't feel amazing about this

things weren't quite as flat as I

thought that they were at the beginning

so we've had to take off a lot more

material than I thought I'm afraid that

were still quite a ways off of being

flat so like you can see kind of like

here we haven't even touched it with the

surface plate yet and right there as

well

so that means that there are really big

high spots there and there so kind of

like around the edges here and in the

center was a lot higher than like

because we'll be contacting the silicon

around here and then read around the die

it was higher I'm a bit concerned about

how much crap I got all over the CPU we

run like these little resistors here I'm

not sure how I'm gonna get that out on

the other edge there's like it's just

kind of all over the place I'm not

totally sure what to do I think that

Riley brought me in so that things

wouldn't be dying like geez this is um

I'm not totally sure how many people

would recommend this but uh I certainly

we and we haven't even told Linus we're

doing this so hopefully the other thing

is that when you use water and you like

put it all over a processor the water

can kind of stick around so you want to

just dunk it in alcohol first and then

that that was shows it away and we

should be good to go

definitely do that I have no doubts that

this will work flawlessly good me too

some time to play with a $2,000

processor hopefully you didn't break it

here we go was this worth all the

killing the processor we we will find in

questionable for sure but wasn't worth

it for the views though if we get them

yeah everyone's gone we got into the

BIOS yep didn't kill it

excellent boo-boo so we're idling at

about twenty twenty eight degrees or so

which is about the same as last time so

we might be able to actually beat like

Nutella or diamond paste using though

being ATO that's that's climbing fast

right that's bombing really fast o beat

the diamond paste eighty nine we still

have a little bit of room still a little

bit ninety it's a really similar

trajectory to the diamond paste

ninety-three C but that's what's that's

so surprising like why was the diamond

paste so bad I don't know because this

is bareback and it's it's doing very

similar this is nothing and it's doing

very similarly so it's back down to like

ninety three degrees so okay flattening

it did help a bit it seems to be better

than the diamonds but uh so if you want

to keep under load you know you want to

keep it in a nice frosty ninety four

then flattening is yeah it's great good

to go but I guess if you actually want

to keep the cool toothpaste in petroleum

jelly excellent option yeah diaper rash

cream also pretty good if you have it

around not horrible

mustard surprising winner but also don't

toast it and surprisingly diamond powder

with anything not as good as we thought

so I see diamond must have some sort of

like secret you know secret recipe or

something yeah or it's just way finer

than what we had

I don't know at the end of the day you

know we found that some materials can

actually work for a hot minute or

minutes but on the whole you probably

want to use thermal paste so if you're

if you're really desperate you might

turn to something else but for the most

part just go to the store pick up some

thermal paste order some thermal paste

like 15 bucks on crime probably it's not

bad guys something else you might want

to pick up is the sound core infini Pro

buy anchor the infinii Pro is a 2.1

channel sound bar with Dolby Atmos an

immersive 3d audio technology that

doesn't just pump sound at you but above

and around you the infinite Pro uses two

built-in subwoofers with base up

technology to produce booming lows then

fills out the sound with two full range

speakers and two tweeters and with the

ability to pass 4k HDR signals through

to your TV and wirelessly stream audio

from your phone or tablet the infinite

Pro is one of the best value dolby atmos

speakers conceived by humankind so check
