For those of you that frequently use an external monitor with your MBA (revision D), do you have a lot of fan noise just by running the monitor? - Also, do you have a lot of fan noise in general? I had a first gen MBA and OH did the fan run all the stinkin time. ALL the time. Youtube video? Fry my lap and blow me over the fan got so windy. It was incredibly annoying. So for those of us that either snatch up a current model, or the refresh, do we have anything to worry about? ... (point of ref: -my previous gen.1 MBA had largely inferior specs, ran fan all the time and choked. -my current 2009 15"MBP w/ 2.53C2D, 9400m, 4gigs, never has a problem like this and never ramps up the fan. However I do understand the MBP chassis disappates heat better than the smaller MBA). Thanks.
