Gainward – GeForce RTX™ 3080 Phoenix thermal pad sizes

Watch thermal pad replacement video
VRAM front:80x40x1mm
Front of PCB:1mm

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.

    Dados da vram estão incorretos

  2. Thickness is 1mm all over on the front side. Post has been fixed, sorry for the mistake.

    Короче у кого такие карты с черной подложкой между радиатором и памятью. С ОБОИХ сторон на подложке на память нужно ставить 0.5мм. 1мм МНОГО! ГПУ не достает до охлада. И юзайте мягкие термопрокладки типа Одиссеев

    In short, who has such cards with a black subplate between the heatsink and the memory. On BOTH sides on the subplate for memory, you need to put 0.5mm. 1mm is a LOT! The GPU doesn’t get cold enough. And use soft thermal pads like Odyssey

    In video, the thickness of the pads is about 2.0mm. What is the correct thickness??

      Vram thickness 0,5mm is correct. At least for “card with black subplate between the heatsink and the memory”, as was written above. Same for gw 3080 phantom.
