Several questions about GPU overclock

[Lubberkin]

Hello, recently I decided to overclock my Gigabyte GT 1030 OC Edition GPU to reach 60 frames in a game, because it was my first time doing overclock I have several questions.

1: I used this configuration (pic related) in Aorus Engine, then click Apply and start playing, is there something wrong with this configuration? Should I increase the core voltage?
2: When I click Apply on Aorus Engine and then run a game, there are times when the screen turns black or the game crashes, it only happens the first time, if I open the game for the second time everything runs normal and Overclock took effect, is this normal?
3: When the GPU is in full load it reaches between 69-74 degrees of temperature (Overclocked) with fans at 68-70% speed, the strange thing is that the gpu reaches these temperatures also when it is without overclock (under full load too), why does this happen? -This temperature shortens the useful life of my GPU?
4: Whenever I finish playing, I change in Aorus Engine to my profile 1 (default settings without overclock) then I click Apply and close (I do this to return normal values to the GPU), should I always do this when I finish? or just close the program and go?

Just leave the voltage as is

no.. Try a different software after removing this current one, say MSI Afterburner

because power limit is not changed, which means it's still drawing the same amount of power and producing the same amount of heat

No need to remove the overclock when you're done, it automatically drops the frequency back down when you dont use the power

Thank you very much for your answers! I have one last question regarding overclocking ... This will reduce the useful life of my GPU if I keep it in the values shown in the image? I will not increase them more. I cannot afford to buy another GPU because my country is going through a complicated economic situation.
