It's not as quiet as the White ones IMO. Especially when a lot of video activity or multi core activity kicks in, the fans goes much faster than on the core2duo ones. I have the idea the 9400M GPU in my 2009 is passively cooled or so. But HD4000 and 8thread machines are a lot faster! Now you have a Mini that can stand against an iMac. In de Core2Duo era, the Mini's were quite a bit behind the iMacs in power. My Radeon 2011 mini also blows pretty much during a GPU intensive game.
