Sounds like a water pump going?

I am experiencing a strange noise. At about 2000-2100 rpm before the fan kicks in, I am getting an internal (towards the forward) engine sound like a shaft is spinning and a resonance occurs... rattling, maybe a bad bearing. But when the fan kicks on, that sound completely disappears and the engine is as smooth as day one. Any ideas?
