Vlad As I said on Discord as well, I wouldn't worry about my fans. GitHub's homepage in Orion now has the same effect on fan noise as Chrome, Safari. I also edited my comment to say "spin faster" instead of "go crazy" to better describe it 😅.
This is on an almost 10 year old MacBook Pro. I didn't mention fan noise as a complaint. As far as I'm concerned this issue is fixed in the last RC.
