The bios lets me set fan speed based on temp and it generally runs quiet even watching 4K video. If I compile code on all 8 threads for over a minute it will speed up. The CPU should be the hottest part, and one of the bottom vents is near the SSD, which is on the bottom of the board I've got. The air coming out on any side is not generally very warm.
I think a good update could reduce the overall height by 5-6mm (10 percent). Being able to relocate the fan hole is critical to support different PCBs since CPU location is not standard.
