You all in the MBP world may not be aware but there is quite a riot going on in the MBA world regarding fan speeds. Just wondering, what does iStat show the MBP fan speeds are under light load (say surfing, writing) and under moderate load (say 30% steady CPU utilization like watching a video stream or installing an application)? How about with gaming (although the MBA doesn't really game)? The MBA is 2500 rpm/50C and inaudible when it is behaving and 6200/70C+ and loud when it is not behaving. What's it like in your world? PS Penryn models in particular.
