    Has anyone tried lapping down the heat sink and the IHS to promote more uniformity between contact points before using any type of ic diamond, carbonaut or this pgs? In the very least it could eliminate some amount of variation.

    My laptop thermal throttles like mad. I am going to upgrade the thermal paste because according to forums it is absolute trash, but should I also add a thermal pad onto the underside of my laptop touching the heatsink (connected to the bottom part of my laptop), or would it not be worth it?

    The best thermal interface material would be not to have to use any. Any additional component between the cpu and the cooler adds thermal resistance and therefore decreases the thermal conductivity. The problem is that surface roughness and precision of the geometry of the parts are not in a way optimal that you can have two surfaces fully touching over a large area. That is where thermal paste comes in and why you need it in reality. As a tolerance compensation. The pad probably cannot work in that way. What would be really interesting for a future video is you getting the CPU lid and cooler surface as flat as technically possible, mirror polishing it and mounting is directly to see if this way the performance is even better than with the best paste you have.

  • KrypXern

    Everyone here is talking about the thermal conductivity of the material without even once considering the thermal conductivity of the interface, which is 100% of the reason you use thermal PASTE instead of a thermal wafer.

    Gee Linus why not got to a pawn shop and buy an old silver dime or quarter and sand it smooth and polish it to see if it transfers heat better? Though I doubt you would find a diamond wafer.

    but doesnt the adhesive get in the way. why not try a piece that doesnt have adhesive so that both side contact and spread heat through. and also does it move heat only one way or is it to just repel heat

    Why don't you try spreading thermal paste on the cpu then applying the sheet?

  • TimeBandit

    Like im a dumbass so prolly dont wanna listen to me but like what if you used the graphite on the heatsink panels themselves? like take the heatsink apart and put a layer on either side of each metal fin to distribute the heat over the entire surface meaning more cooling?

    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.

    What people need to understand is: Why do we need something between the dissipator and the CPU? It is to "fill" the imperfection on both surfaces. You don't fill imperfections on a solid surface.... with another solid.

    • MrCh0o

      Well, you could, if it can deform enough under pressure, e.g. a soft metal foil with heavy screw pressure could make contact with the edges of a convex surface or center of a concave one, which is really the more important part. And some larger cavities could also be filled that way

    It might take a while for this to happen, but I think they should try making an entire heat sink out of that material.

  • LeonG

    of course graphene is electricity conductive. The first thin layer on showing contact with only part of the CPU lid .. its not the area of the "Die" (chip) that is relevant..the heat is spread out to the entire metal lid.. so you need contact with the entire lid to take the heat from it... one reason the graphene its not naturally sticking to metal, thats not assistting with removing the air bubble, the air bubbles just move around as a result of the nonstickyness.. and you know what, the extreme thermal conductivity of the graphene is of no benefit if the glue is less thermally conductive.. and of similar thickness... you get no great benefit.. you could just use the glue with no graphene ! You only want some other material if you can save money by not wasting your expensive glue on filling the gap.. its not terrible to have graphene inside a thermal pad, but its not glue and its always going to be the glue stuff that is critical.. to remove the air bubbles ...

    The only way this would be beneficial would be if thermal paste had a much lower conductivity than the two surfaces it is squished between. You could have a thermal paste with 1 million times the thermal conductivity, and it wouldn't make much of a difference because the bottleneck would be every other material involved in heat transfer and heat exchange.

    I wonder if the adhesive is a bottleneck? Like, the graphite is conductive, but theres still a layer of adhesive heat needs to go through. Maybe folding the graphene would yield a better result?

    Isn't the point of thermal paste and pads not just transferring heat, but filling gaps/voids? Something this thin fails that goal - you'd be just as well bolting the heat sink directly to the CPU's surface without any thermal intermediate - right?

  • JanuszKowalski79

    You need to remember that this carbon sheet is very very thin. The thing is Linus was using his fingers to put this piece of sheet onto cooler. I would expect a lot of grease which will 100% affect performance.

    The reason this doesn't work is because all thermal paste is doing is smoothing out tiny imperfections on both contact surfaces to eliminate air gaps. Thermal Conductivity is just a bonus.

    00:37: bs then... goodbye :)


    TIM only exists in this application to displace air. The thickness is so thin that virtually anything will do - and we see that in the 1-2 degree spread in coolers The pad fails because it doesn't fill air gaps. most pads fail because they're too thick and.or leave air gaps Try it again after lapping your surfaces (or using something to fill the surfaces)

    Panasonic's own test data shows only comparable performance to average grease. Most likely applications: where electrical conductivity is critical to function in addition to heat transfer, where viscous materials would cause potential pump out/reliability issues, or high temperature applications that could negatively impact performance of grease. Also, aligned graphite material such as this has highly isentropic qualities, the resultant in-plane thermal performance is quite high (1200 or more), while the normal plane (the direction straight through the sheet) is considerably less (perhaps only 20-40). Also, a very significant component of total resistance of a typical CPU to heat sink thermal interface assembly isn't the bulk thermal conductivity of the thermal interface material. The is contact resistance, or how well the adjoining solid surfaces couple heat through to the bulk thermal interface material. This is where flatness, roughness, pressure, and the particular mechanical qualities of the thermal interface mixture, which is typically a combination of liquids and solids come into play. This is also where liquid carrier materials such as greases can have an advantage over solid materials as they are simply better able to fill out any voids and gaps.

    Apply to both heatsink and CPU...BUT, still apply liquid metal between the pad layers! Also coat the heat sink fins with these pads!
