A330 Freighter
The new A332F Freighter recommends, pack 1 off (pack 2 remains on), then open the outflow valves, whilst descending to FL 200 and allow the cabin to climb to 20000ft. This takes time, but consider you may be 180 minutes out to sea on an ETOPS flight when this all happens. We have 180 min ETOPS with this new A3302F.
That's too far out when when the main deck is getting hot, so I would do it definitely!
