Should I re-seat my cpu cooler?

Hello,

I have a peerless assassin 120 on my 5700x3D although I am not sure if it is properly seated. When screwing it on, I overtightened it quite a bit before reading that this can damage the motherboard so then I loosened each screw haphazardly and probably not very equal.

I now worry that my cooler isn't mounted properly in that it may not be pushing down on my CPU equally. My temps are 45C degrees idle and 75C degrees running Cinebench multi core.

Is this anything to worry about or am I in the clear?

Thank you
