Sometimes, just sometimes, the gasket between the exhaust manifold and the
exhaust system can fail in a way that results in a mechanical-type rattling
noise. Generally, however, the water pump is the prime suspect. And even if
you've tuned your fan belt to the perfect tension, these things have
relatively short lives.

When I replaced it, the noise went away. YMMV, but it's possible that
you've had your fanbelt too tight, leading to premature failure of the
pump bearing.
