SAPPHIRE – Radeon RX 5700 XT 8GB thermal pad sizes

We have no exact sizes for the pieces that can be seen in the video but approximately you need at last two packs of 80x40x1mm on the front side – in between the heatsink sandwich – and one pack of 80x40x2mm for the back – in between the backplate and the PCB.

Watch thermal pad replacement video
Front:1mm
Back:2mm
Suggested brand:GELID

Sizes guide

  • The scrissor sign next to a size means it can be cut out from that slice of thermal pad. It is not the actual size! Example: 80x40x2mm
  • One dimension size means it’s the thickness of that pad. Example: 1mm
  • Two or three dimension sizes – with no scrissor sign – means it’s most probably an actual size. Example 100x14x1.5mm

About sizes

Sizes you find here come from various sources. Most of them reported by my clients whom successfully replaced their GPUs’ factory thermal pads with high quality aftermarket pads – getting significant results in their temperature drop. Some of these sizes are actual measurements and others just collected from random users on such websites like Reddit, YouTube or official / unofficial forums.

Do your own research

Please note that I cannot take any responsibility for the sizes appearing here. Do your own research as well before buying and replacing anything.

Tips

  • Make sure your pads and GPU die contacts well with the heatsink.
  • Always test your graphic cards and devices in controlled environment.

    I used 3mm in the back since there is too much space when you use 2mm. Works perfect.

    I used 1.0 , 1.5 and 3.0 for my ASRock RX 5700 XT

    Teared down my 5700xt pulse, replaced all the thermal pads. Here are the exact spec:
    For the memory chips (shown in the first pic) it’s all 1mm (including the small chips at the same place).
    On the backplate there are two sizes. 2mm on the 7×7 chip. And 3mm on the long one (shown on the second pic).
    I bought 1+2mm and placed them on top of each other for the 3mm one in order to be cost effective. Worked perfect. Enjoy!

      Thank you very much for that info Jake, I followed your numbers and it’s an outstanding silent performance after that… Everyone having this GPU and having high temps, this is the way!

    On a Gigabyte RX5700XT OC Gaming, do you know the correct thicknesses to use?
