Do they have the whine to begin with or does it start over time? Also do mac stores do the replacements?
Brand new to Macs - have had my MBP (2 ghz) for 3 weeks or so.
It's had the "whine" since the beginning - which I hardly notice anymore. The only time I do is when the room is absolutely silent, and even then, I don't pay much attention to it.
It does get hot, but I downloaded one of the fan control programs (forget which one, and I'm not on it right now), which helped tremendously - even without manually setting the fans to obscene speeds.
Those are my only "complaints." So far, I love it. Of course, the fact that my previous computer was a 4 year old Compaq laptop with floppy hinges, broken keyboard/power button/headphone jack/screen, and 40 minutes of fully-charged battery life may influence my opinion somewhat... nah, it's great.
