No worries about measurement, no issues with pad density requirements. Putty conforms to just about anything and in most cases has higher performance than pads. Its mostly reusable. The putty that is very messy in this video is actually a mix of a thick putty and a near paste like putty which is why it appears so goopy. I have been using putty for almost 2 years and have not looked back after maybe 75 cards or so. You see in this video that the blue putty is actually AMD factory, and I reused it for other components. Pads will have their place, but I pretty this stuff 10/10 times.
I have many opinions on cooling and cooling issues with the 7900 XTX. The 7900 XTX die size is so large that even at high wattage its thermal density in mm/sq is roughly the same as an RTX 4070. However 7900 XTX's in general do have issues with hotspot temps and I think this has mostly to do with how much pressure the cooler is pressing on the die and how flat the cooler/die is. I have noticed that all the 7900 XTX than have come my way that ran awesome temps on die/hotspot had insanely stiff spring bar mounts. And the 7900 XTX's that did not have good hotspot temps did not have high tension mounts. In the end there is so much die surface area between all the chiplets to get the heat into the cooler I think that a better solution is honestly the factory paste which on most every 7900 XTX is going to be something similar to PTM 7950 phase change material. You never know until you try though right :)
@The_Thermal_Channel that's interesting to know. Thankfully I don't have any hotspot issues on my 7900 XTX but I'm not cranking the power limit up either. I just don't think the performance gain is worth all the extra wattage and heat.
@@jinxPad What I have learned from tearing down probably a dozen or so 7900 XTX's from ASRock, MSI, Asus, XFX and a couple 7900 GRE's is if your hotspot temp delta is good just leave it be. Don't modify, change paste, take it apart. Be happy that its running nice and cool and because most all 7900 XTX's have phase change material from the factory it will not need maintenance for many years. And you are correct, if anything for raster performance these are so overkill unless you are maxing out AAA games at 4k and even then its a lot. You could probably even reduce power 10% and not notice any performance hit.
Why not use thermal pads? That paste is so messy.

so the LMTG not really worth for the 7900xtx then?
