The fan is horribly noisy on this model. However, it will quiet down a bit on its own when temperature goes down...enabling C states and running "powerd -a adaptive -b adaptive" should help a lot...I don't recommend manual fan control as at least my i7 already runs way too hot in linux and win7 (for the 10 minutes I had it :) ). Run Lenovo bios updates as well, many complaints about post tsunami fans from Lenovo China instead of Lenovo Japan... > > What do you mean by the fan controls still work in manual and > automatic?
