MSI – GeForce RTX™ 3090 SUPRIM X 24G thermal pad sizes

Official measurements on second picture came directly from MSI support after a redditor contacted them.

It’s fairly easy to replace thermal pads on the front of the VRAMs but it seems tricky on the back. Like you can see on second attached picture there is a heatsink piece running through the VRAMs, separating them into two pieces with two different thickness. You can either get 1.5 and 2.5mm thicknesses to get it match by the factory pads or you can try with a 3mm and 2mm piece so they push up with the same amount.

Unfortunately an 80x40x2mm and an 80x40x3mm piece just not enough to cover both side of the VRAMs like on most RTX 3080 / 3090 cards.

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.
