Thanks, peter. The one thing I didn't do was to clean the actual fan blades. I will do that immediately.
The noise doesn't appear to be a "whine" that I normally associate with bearing wear, but seems to be more of a noticeable "whirring". If additional cleaning doesn't improve the situation, I'll start looking for a replacement fan.
