I recently had some issues from overheating , crashing, artifacts etc… i changed thermal paste but had some issues with the pads. After searching online it would seem that the pads should be 1mm but after installing the pads i saw that they are not making contact with the back plate the ones near the gpu core were pretty close . The outer ones were way off. I ended up putting double pads since i threw the olds ones and did not have a different size. The problem now is that i see a bend all around the gpu core. Outer ones are fine. I leads me to think the inner ones are 1.5mm and the outer ones are 2.0mm. These pads were really expensive and this process was neeve racking and tome consuming (not my kind of fun). Is there a way to know for sure about the thickness i need before i order a new batch and open my card for the third time? Im providing a picture of the old pads for reference

Measure with a ruler, best option!

How did you get on? making a template can help!

i had the case of a bend card but it was working fine
