The Panasonic Pyrolytic Graphite Sheet (PGS) has a staggering thermal conductivity of 1950W/(m*K) - but is it as good as the spec sheet says?

    I worked for a competing distributor and Panasonic came to our facility to give us training. In fact the people in the video were actually the ones giving the training. The particular pad you were using is really only designed for lateral thermal transfer not thermal transfer through the sheet. In fact their page specifically lists heat diffusion as the main use for this pad. They have a separate product described as Graphite-PAD is a thermal interface material (TIM) that compatibly obtained excellent thermal conductivity in thickness direction (Z-axis direction). You may want to redo with one of the z axis pads.

    Always remember what the Verge taught you: The more paste the better!
  • @alexoja2918
    Fun fact: i've got a valve in the aorta of my heart made of that stuff. Glad to figure out i can re-purpose it as a cooling pad down the line!
  • @RKSNomad
    We actually use this in Central offices. We will have panels running 40KM SFP's (Long range fiber optic lasers) and we use these to spread the heat across a mass heatsink that then gets bucks of air blown through them. it increases laser life so much. an SFP that would need replacement within 5 years would last 15. EDIT: I should note, i am talking about national infrastructures. these guys work with petabytes of information, not terabytes.

    Linus : "we spent 40 $ on this little pack?!!?! :O " Linus : "so i ordered 6 BlackMagic 12K cameras"
  • @FergyA
    Graphite tends to conduct more laterally than through its thickness. I suspect that's what you're running into.
  • @zoeyamon935
    I love that even as Linus gets older he has the spirit of an energetic teen. Always entertaining to watch.
  • @JeffBastian
    Graphenes are good when it comes to their in-plane conduction, but not so much in the out-of-plane direction. So, I'd think that it will do exceptionally good to spread the heat where heat pipes are a non-option.
  • Graphene reaches its highest thermal (and electrical) conductivity across the plane the carbon atoms are layered. In this application, you are only using a fraction of this material's capabilities
  • @XxM1G3xX
    MKBHD: I will try to do a smooth segue like linus does Linus: 360 no scope segue
  • @VoVilliaCorp
    Linus: Wait, we spent $40 on this little pad? Has mild stroke
  • @XalphYT
    2:40 "You haven't even opened this, have you?" "No." "You have no idea if this will work." "Not at all." This is the best type of video: We're going to get to watch their successes and failures as they experience them.
  • @jap00_39
    Linus mad about spending $40 on thermal pad but he just killed a i9 then bought a new one
  • @gavinh5618
    Today: “We spent 40$ on this little pad?!” Literally a few days ago: “I will pay 10,000$ to the first person who sends me this 12 year old monitor.”
  • @KingCarrotRL
    Nice to see Ting as a sponsor again, I've been using it since it was last advertised here.
  • @adamd416
    Your content keeps getting better. The beard is great and I love to see the confidence grow! Keep it up Linus and ltt team!
  • As a chemist, I always hate watching Linus do this stuff without wearing any gloves. The idea of fingerprint oil getting on that sheet is maddening!!!
  • @pepethunder
    Linus: "This pad cost $40!? Pikachu face" Also Linus "Buy my $30 dollar water bottle!"
  • Thanks for doing videos like this, always seem interesting and I know it's one of your passions. Tech is always interesting.
  • @loocheenah
    Your display is so cool and responsive to the point it's so nice even to watch it from my phone
