I am on my 5th MBP now and this one still has issues. Since installing upgrading the firmware and installing bootcamp the latest one has the fan on constant. I'm sure after doing this on the others I have had the fan would only cut in when it was needed. Does anyone else notice if the fan is on all the time? I have also found that this MBP has the mooing problem. When it gets hot I hear a fan try to kick in on the left hand side it strains for about a second and then stops. It does this every 10-20 seconds. I also have the whining issue but I am prepared to put up with that. I don't want to have to take this one back but it is quite annoying.
