Where on the GPU is the reading for GPU Memory Junction Temperature located?

My brother has a 3080 ti strix, and I'm interested in learning where the reading for GPU Memory Junction Temperature is located—is it on the front side where the GPU die is located or is on the back of the GPU?

This is the hottest internal temperature (inside silicon) among all GPU memory chips.

Thanks for the reply. I changed thermal pads on both sides of my brother's GPU, and I saw GPU memory Junction Temperature go up. Can you please look at the picture and let me know which side affects GPU memory junction temperature? Is it the front (1) or back (2)? I'm trying to figure out which thermal pads to replace.
