5:14 It literally surpases the best thermal paste and liquid metal….doesn't keep up…what….? Your entire video on that showed that it performed amazingly. Why are you now all of a sudden saying "it's good enough" ??? Wtf?
at least that's what I remember as the clear take away from the video you did two years ago.
#1, application competence is lacking. Peeling away the protective layer and waving it around while touching it with your fingerprints, etc. #2, Some sanding of the contact surfaces would improve contact performance. #3, If you can not use the scientific method to demonstrate something when you are trying to compare something scientificly, then don't do it and say you did.
PGS Are good at conducting heat in the x-y plane, but very poorly in the z plane. You are also missing the point of a thermal compound. Thermal compound fills in the minute gaps between two solids for effective conduction. The solid PGS cant do that, since it is a solid material itself. You are just slapping an insulator in a heatsink that already has no thermal compound, so it can only do worse.
SIR. Pyrolytic Graphite conducts heat excellent along the x-y plane, almost as good as diamond. But it doesnt do well in the z plane. This pad wont perform very well transferring heat through it as you are using it to do. There is vertically oriented PG that can do it well.
Do they make thicker sheets, like 0.1mm at least? And not $10000?
I think for this micron thickness you would need to 1000 grit sandpaper both surfaces first. And also plane them. So start with flat mirror finish essentially.
It didn't work for you because NH-D15 bottom is concave to hold thermal paste, leaving a big hole of air and CPU IHS is convex. Same why IG Graphite didn't.
One thing I always enjoy about your channel is you folks are always trying new things that you find. I’ve learned so much just from you all messing around and experimenting, thank you for that.
Any chance of trying again with lapped components? The conductivity could be a million but it wouldn't matter if there were air in between. Also, the spec sheet says that the quoted conductivity applies in plane; perpendicular numbers are between 10 and 26 (which, because it's a lot thicker than thermal paste interfaces, makes it a lot WORSE than thermal paste).
Hey anyone wanna put down the stuff he said in the intro in simple terms it sounds super interesting i just dont understand it all that well, thank you
how would it be to wrap that thing around the ihs and add liquid metal or other product normally? or stick it on heatsink finns so heat blow over them and let them "flap in the wind" should be a great way to increase the area of the heatsink.
A high school student tried a bunch of tests with various heat pastes, and showed that even a drop a water will work – until it evaporates. His conclusion was it's all about wetting the surface.
What if you put a layer of thermal paste between the graphite and the IC/Heat sink? at that point, sure, you've defeated the point of using the pad, but it'll probably get better results due to filling in all the gaps that a very, very flat material will leave on a very not flat material.

What monitor is that??

It's so annoying watching you not be careful with things. You have the finesse of a drunk blind person.

2:31 ……. "nice" … rips bong
Lol 98deg. How many of your staff are old enough to get that reference?

Carbon nanotubes have a thermal conductivity of about 3500W / (M*K).
Linus: or sponsor ting
cpu in the bcak : am burning!!!
9:23 Linus has a Heartattack about the Price…
Hey Sasquatch get a shave… 😀 😀 😀
Now we need some Liquid nitrogen. Then were overclocking ready
Why not try the thicker variants? Or fold it over itself multiple times on the cooler? I'd like to see results of proper full tests. Would be great.
Do you guys have enough thickness?
Graphene is cool, we should use graphX
Me: *When LTT uploads a video finally he has not made a video in 2 days
Linus: * I just uploaded recently
Actual tests beats the specification, ask a World of Tanks player!
Just got the notification that you uploaded
I wonder if this would work well as an undercoating for cookware? Cold spots in frying pans on electric stovetops are a problem.
Great, you got it dirty with greasy hands and put it on the cpu, congratulations …
I wonder if they take the material and make a radiator would it work then?
You've already showed these off in the past. You held one while blasting it with a torch and burned yourself in the conference room.

I really love your video's guys keep it up godbless and godspeed
ااااا

@05:10 holy crap that look like linus from 10 year ago not 2018

…it's over the heads of the linus team? Well I guess that means it's well over mine
10:25 linus showing off he's an alien…
12:17 98° band pun i see you Linus.

Would lapping help? Since the material doesn’t fill gaps, maybe polishing both surfaces flat might help
Only folks from the 90s would have understood that joke 🤣
How does he check the temperature of his cpu?
LTT the only people whose test bench has more bling than most peoples home setups.
They should sell a version without adhesive, it may be a bottoeneck.
My mother's Nissan has a heated steering wheel but I doubt I would find that stuff in there.
There is a curve on the top of processor IHS to flat it u have to sand it off with sandpaper until u see copper surface
So, mayonnaise actually works better?
