Hi all! Long time lurker I just upgraded from a Macbook Air 13.3 1.86 2GB 128SSD to a 13.3 2.13 4GB 256SSD, and well, I get between 10 to 15 degrees of difference in CPU Temp between the 2. Test of the 2 computers side by side: - Chrome - Gmail tab + Youtube tab Running a 5 minutes video - iTunes Macbook Air 1.86 peaking at 58 Celsius Macbook Air 2.13 peaking at 70 sometimes going to 71-72 Idle, about the same around 48. When I do some light tasks on the 1.86, will rarely reach 50, while the 2.13 will easily go near 60 degrees with iTunes playing, and browsing non-flash pages. Right now, I've my 2.13 hooked to a 27 Cinema display, 57 degrees with fan at 3008 RPM, no flash windows, VLC player streaming shoutcast with less than 2% CPU Usage. Big question is, normal behavior, should I return? Computer does heat more easily but doesn't overheat and didn't crash on me, but he definately is warmer to the touch, and it kinda bothers me after having experience a quite cold laptop that was my 1.86 2gb 128. Not sure if I'm being paranoid, it's the feel of the extra heat that led me to install stuff like istat pro and smcfancontrol.
