3070 Gainward

Gainward – GeForce RTX™ 3070 Phoenix thermal pad sizes

According to one of our user, Gainward RTX 3070 PNY (3070 XLR8) share the exact same cooler design, so the following sizes apply to both model.

All pads are 1mm thick and approximately, you will need at least two package of 80x40mm the cover all required parts.

Picture is from Gainward, however Pad A (11) and Pad B (10) sizes look wrong. They both should be between 40x15mm – 50x15mm.

  • Pad A (11) 73.7×5.2x1mm (probably wrong should be between 40x15mm – 50x15mm)
  • Pad B (10) 82.1×5.2x1mm (probably wrong should be between 40x15mm – 50x15mm)
  • Pad C (12) 27.1×14.2x1mm
  • Pad D (1) 61×5.5x1mm
  • Pad D (7) 9.5×9.5x1mm
  • Pad D (3, 4, 5, 6) 7x7x1mm
  • Pad D (2) 62x7x1mm
  • Pad D (8, 9) 20x7x1mm

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.

    Just the one package of 80x40mm will cover all required parts in the diagram. I just finished refurbishing this exact model.

      I have a question about the pads. Which thermal conductivity should they have? Is 11W/mK enough? I hope you can help me.
