How hot yall getting your cooktops for salmon?

I like to cook and watch Michelin star chefs on how they do things and try to replicate it. My mom likes salmon so I want make her some next time I fire up the BS. Fish has never been one I have done much with since I personally am not a fan. I found one video I want to replicate from a pair of chefs I watch but they never say how hot they get their cook tops/pans. They just say "nice and hot". If I am doing steak, I am getting that thing up there to get a good sear, but I thought fish was a bit more delicate. So I am curious, what temp should I be aiming for my cooktop?
