My original PS3 that I got on release only had 2 fan settings: off and the other is still waiting for the World Meteorological Organization to give it a name.
Slim has been a dream. I mainly run from HDD so it is a bit of fan noise (very quiet) or the odd whirr of the hard drive. The disk is another thing entirely. That chunks and whines like some sort of dockside crane machinery. It *isn't* bad in the grand scheme of themes, but it does ruin late night low volume gaming/video. However, in the world of PSN+, 90% of my stuff is now HDD based.
Slimmy slim, no idea of this thing. The cheap looking casing doesn't give me hope though. I have no urge to upgrade.
