Very High CPU Temps
It says right in the video that the temperatures were taken in a room with 21C ambient temps. So 7-11C lower than your situation. If you add that to the 71C Steve got, you get average temps comparable to yours: 78-82C
If you look at 4:50, you can see Cinebench temps shown as ~65C. So again, if you account for the temperature difference, it's in line with your stock result.
As for why your 3900XT ran cooler, if I recall correctly, the XT chips have better silicon than the originals. AMD said they were the result of optimizing the 7nm process, and they typically ran with lower voltages than the originals, which means lower power consumption and thus better thermals.
And every chip has some variance. There's a chance that you really won the silicon lottery on your particular 3900XT, and it can run cooler than usual, while maybe you weren't as lucky with your 5900X. Although again, when you look at Steve's numbers, yours are comparable.
My 5900X cooled with a Scythe Fuma 2 runs about 55C over ambient in a productivity workload like Cinebench, so in your heat, that's 83-88C. Your AIO is doing 8C better, which is a solid result in line with what I'd expect for a 360mm.
