The i9 is a warm chip, so I’d expect the fans to spin up a bit 
I’m glad to hear that the temperature is better than the Wine version. The Native Mac Client is much more optimised when it comes to resource use!
Ensuring v-sync is on is by far one of the best ways to keep heat / fan management under control. I strongly recommend leaving it on.
We did a pass of shortcuts since the last update, so I’m glad to see it got noticed so quickly 
. The client should also match OS shortcuts for moving between words by using the alt/opt key. We have a few more minor changes to make, but most people won’t notice them
