I have tried that watering with ice cubes once with one of my Phals, but I timed it when our temps are just sizzling hot, like triple digit outdoors and indoors going mid 70's, with our ceiling fan running. But will never do it during the cold weather season. But for newbies, will not really recommend it, I feel they should know the orchid and understand its basic cultural needs, before attempting short cuts.
As with any of my orchids indoors or outdoors, Phalaenopsis or otherwise, apart from good drainage, people often forget providing good air circulation. These plants enjoy it a lot.
