When you increase speed sound becomes more frequent or louder?

Make sure nothing is touching the fan blades.

Have you tried running the fan outside of the case and holding it in your hand?

If that's the case, contact either the store or Noctua for a replacement.

Ask? 

One more thing I forgot to check on:

What are you using to power the fan?

Is it the cpu_fan header? It will usually offer the best pwm signal.

The fan might just be defective then and asking for a replacement would be a good idea.
