Hi all, a question popped up in my head today connected with the PSU fan grill. I was wondering, since a large number of cases has the PSU bottom mounted facing the floor, do a PSU need a grill? Will it be quieter or cooler without it? Put the warranty issue away for a second. I ask hypothetically. I searched the Net, but no consistent results showed up. It's like one of those topics for example: how to install thermal probes from a fan controller (there is no recent and decent guide for this one). But my point is, is it possible that manufacturers release a PSU without a fan grill? What do you think about it?
