Should I make a thermal maintenance on my GPU?

You're probably fine. My used 3070 was probably running over 90C for ??? time with the previous owner before they sold it and works like champ for me after a repaste. Was there some silicon degradation in there? Maybe, but for $220 it's great and I don't run it at max except in benchmarks. The rest of the time it's chillin' at ~170W and 60C max.

Your GPU clock is super low there, looks like you may have gone overkill with the undervolt/underclock. For reference, my daily driver MHz on the 3070 is 1875MHz at 0.893V. Even with a conservative clock and UV like I like to run, you should be in that general range depending on silicon lottery. I only see you hangin' at a low ~1000 MHz in that chart.

Good catch, but I only decreased the power to %75 in MSI afterburner. Here what it looks like in full throttle:
