- Download the QuietMBP application. This simply gives the processor useless tasks when it's idle, and was created by a frustrated Macbook Pro owner suffering from the problem. It works well, and by dragging the program's slider, I found I could even manipulate the pitch of the whine. The only issue is that battery life might be affected, although you could always quit the app when away from main power.
- Start PhotoBooth and minimise it to the Dock. For some reason, using the iSight causes the sound to disappear until PhotoBooth is closed. (Other apps that use the iSight, such as ProScope HR or the Mirror widget, also cause the sound to vanish temporarily).
- Turn off one of the processor cores. This can be done by installing the CHUD tool from the developer directory of the Tiger install DVD. This will then add a new entry to System Preferences called Processors, and it lets you switch off one of the CPU cores on the fly. I'm not sure this is 100% safe, because you're using the chip in a way that it wasn't designed for. I also find that the fans tend to spin-up when even trivial tasks are being done, because all the CPU work is being loaded onto one core.
