There's probably comparatively little energy actually going into sound,
considering that typical cheap-ass PC speakers putting out 3 or 4 watts
per channel will comfortably drown out all but the noisiest fans.  And
yeah, the air movement from those fans probably becomes waste heat in
fairly short order, and does so mostly outside the case, but I doubt
there's a lot of it.  I would expect it's negligible compared to the
heat carried out of the case *by* that heated air.
