I could almost see this happening for light to moderate use (email, web, light graphics, music). As I mentioned before.. takes some time for my 1st stage fan to come on at all.. Been working for 3 hours this morning already and haven't heard a peep. HD is getting noisier these days though.. I think this all has a little to do with the fact that 550 owners got jipped out of the L3 cache.. Just a little less to cool? I don't know actually. I will happily trade my mint condition extremely quiet desk queen 550/combo for a 867/Ghz machine! hahahaha.. I am sure someone will chuckle at that.
