It's crap man. It's faked. That mobo has a hole cut in the back with a firecracker up in it.
The fan on the HSF isn't running and if you look at the pics after it's over you'll notice that the core is still intact aside from being chipped up a bit. If it had been running ay 4+Vcore and violently burnt up the core would've atomized upon him removing the 'sink.
