hey guys, sadly i think i'm forced to return my 3 day old mba. rev b, hdd. i was willing to accept the "chirping issue" coming from my hd that was deemed "normal" by a series of Mac Genius'. However, the fans are kicking in very loudly when I watch a Youtube video's in standard def or a trailer at the Apple trailers site. The last time I watch a Youtube video (with mail, firefox, and tweetdeck open), my fan went to 6204 rpm's via istat pro. I can't have handle my fans revving up when I'm doing such basic tasks like watching a video on youtube. (Photo of Istat Pro attached) . Curious to know if current MBA owners have the same experience with Youtube use, etc. Really a shame because I love this screen and the light weight is amazing.
