Kinda hard to tell, but doesn't look like there's any fan at the base where the PSU is. So one big fan at the top sucking air in and blowing it down and out of those exhaust holes at the rear? They wouldn't pull air in through the PSU from the base first would they? It's always been through the console and heat sinks first and then past the PSU before the hot air exits. You don't really want hot PSU air being used to cool the APU heat sink.
