5700 XT Sapphire

SAPPHIRE – Radeon RX 5700 XT Nitro+ 8GB thermal pad sizes

Approximately, you will need at least one package of 80x40x1mm to cover all the VRAMs on the front side.

With another package of the 1.5mm thickness, you can cover the rest of the front side. And thus, a stripe of 3mm is required to replace the backplate stripe.

If you have some thermal pads left, you may can put some additional on the backplate, such as areas that are contacting the back of the VRAMs to reach better heat dissipation.

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.


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