My MBP is in for repairs. No problem, I'm thinking, since I've done a Time Machine backup and I have my backup MacBook (2 GHz, 4 GB RAM). I wipe the drive, load up Lion on it and then restore my MBP's system on the MacBook. No issue, except for the fact the fan runs at full blast 6200 RPM when I'm BROWSING THE WEB. No crazy flash video, either. I can run full-screen video and not a peep out of the fans. At first I was pretty sure it was Spotlight indexing, but that's come and gone. I have my RSS in the background, Mail, and maybe a few other apps open, but full blast continues unabated. CPU load barely, maybe 40% at peak. Running at 65 C Have reset SMC, PRAM, and run a full system diagnostic. Nothing. This is clearly related to loading Lion on this machine, since I was running this machine with no fan issues before on 10.6.8. Should NOT have spent the $30 again...any ideas?
