I want to dissasembly my laptop for SSD and RAM upgrade i am thinking about changing the thermal paste too. But in this video, when he is removing the heatsink, there are two thermal pads beneath it. Where i can find a information how thick they are? I have two packs of Thermal Grizzly Minus Pads, first one that contais 1mm pads and second with 2mm, but I don't know if they will fit. Model number of my Swift 3 is NU-SF314-56G-58J0.

    I can confirm now that thermal pads are 1mm thick.

    Hi @hivonzoooo

    Using a thermal pad is as same as using a thermal paste, I recommend you to use thermal paste, but if you want to use thermal pad, you have to use the 1mm thickness, on the other side, higher thickness allows it to absorb more deformations in the chip/heatsink surface, but it is worse in terms of heat transfer. Yes, thicker is worse in terms of heat transfer. Doubling the pad thickness doubles the thermal resistance, you don't want resistance, you want conduction. When it comes to the thickness, it doesn't make any difference it fitting the heatsink and the component.

    I knows the difference between thermal paste and thermal pads. In the video that i have attached you can clearly see two thermal pads near the fan. They have nothing to do with CPU and GPU as they are located at the end od the heatsink. I just wants to know how thick they are to replace them with better ones.

    The Service Guide just says: "Make sure all thermal pads for the mainboard chipsets and VRAMs are in place before replacing the thermal module." The FRU list doesn't have the pads listed, so I can't find info with their thickness. You might be able to measure the thickness when you get it apart, but that's a little late in the process to be ordering the replacements.

    Right now i have Thermal Grizzly Kryonaut and Thermal Grizzly Minus Pads 1mm and 2mm, lets hope one of them will fit.
