Hi people, I have a C2D MBP 2.33 (15 months old, according to coconutBattery). A few days ago I've started to notice a sort of whining noise coming from the machine. At the time, I didn't give it much thought, and assumed it was a HD-related noise, which I hadn't noticed before (I usually use an external keyboard, so the computer is at some distance from me). Today, however, I've decided to check whether it's the 'whining' issue which had plagued Rev A MBP's. I've opened the terminal and did 'yes > /dev/null' as recommended at the time and the whining disappeared. Has someone else encountered similar problems? This is somewhat puzzling and quite annoying.
