Hi all, This is my very first post here. Great forum. Just got the Time Capsule yesterday, left the MBA all night to finish the initial backup. Everything went just fine. In the morning at the office, turned on the MBA and the fan stayed at 0 RPM. Ran some apps just to make the temperature go up a bit, no luck, the fan is still off. Then ran the hardware test and it returned an error with the fan. Took the laptop to a Genius, once turned the laptop on, the fan was fully operational @ 2500 RPM. I was like WTH, it was off all day. Anyway, so far, the fan has been running properly since the incident. It used to kick in (6200rpm) at 62C. Now, it does so only at +80C. The MBA is so quite now! Love it even more! Not sure what happened today, but I'm sure it is WAY better! The fan stays at 2500 almost all the time. Long live !
