Perhaps it is often from lightning struck modems?
The DFAC chips in Macintoshes tend to be closely surrounded by the electrolytic caps of the sound circuit. They tend to just roll over and die once they eat enough cap goop. It's pretty similar to the UE8 and surrounding logic chips in the SE/30, being positioned right next to the sound circuitry and its corresponding caps.
