Gigabyte RTX 3080 Gaming OC thermal pads replacement (20 W/m-K) - same for Eagle/Vision 3080Ti/3090

Walkthrough video showing the process of opening a Gigabyte 3080 Gaming OC to replace the thermal pads with custom-size, high conductivity, thermal pads.

Procedure is the same for the all of the (9) following models:
Gigabyte Gaming/Vision/Eagle RTX 3080/3080Ti/3090 -- all share the same PCB layout

You can now get the GPU custom thermal pad set (and various other pads in 20 W/mK) from there:

Material used:
Cleaning: Paper towel + 99% isopropyl alcohol
Thermal pads: pre-cut, custom set , 20 W/m-K.
Thermal paste: SYY 15.7 W/m-K paste

Results:
Included in the video at the very end
Memory temperature drop of ~6°C under max load (OEM pads were brand new and somewhat decent -- gain would be a lot more significant from "used up" pads)
GPU core temperature mostly unchanged (good!)
