I'm trying to get a realistic idea of how loud a desktop PC is. Online jokes make it seem like every computer sounds like a generator, but is that actually true? What would a normal PC sound like while idle and while gaming or under heavy load?

It varies a lot with the parts and the build. The case, number and size of fans, graphics card cooler, CPU cooler, and fan settings all affect the noise. A quiet build may sound like a soft breeze, while a compact or high-performance machine can get surprisingly loud under sustained load.
Most of the time, a typical desktop is somewhere around a quiet room or refrigerator in terms of volume. Roughly 25–40 dB is a reasonable ballpark, though measurements depend heavily on distance and the environment. The changing pitch of fans can be more noticeable than a steady background hum.
