What problems are going to arise if I turn down my Macbook Pro fans?

My new Macbook Pro 16" is hella noisy. What should I do?

I've just replaced a 2012 Macbook Air with a new Macbook Pro 16". 64 GB RAM; 2.3 GHz 8-Core Intel Core i9.

It's great (I guess, only used it for a few hours) except:

I'm using it in clamshell mode with a Thunderbolt display (Thunderbolt 2 to Thunderbolt 3 adapter), and the fans are NOISY.

Like - distractingingly noisy. So noisy. Noisy enough I'm thinking of sending back a computer I've waited three weeks to get delivered.

(There's no CPU load at all; Outlook is using about 130%, but overall running 82% idle).

According to Macs Fan Control, the fans are running at about 4100 rpm (out of about 5400 rpm max).

If, using that, I turn the fans down to (say) 2700 rpm, then everything is fine again.

However, my CPU core temps are at about 70-80 degrees (SSD 31, everything else low)

Is turning down the fans going to cause issues long term (like, at what temp will a CPU fry?)

If so - do I have any other options other than a) wear headphones b) don't use an external monitor c) return it and move back to using PCs?

(e.g.would another, newer, monitor be better? Is it likely that returning and swapping the laptop would make a difference?)
