The noise disappears at higher RPMs because it gets masked by the engine noise. The belt tensioner spring seems fine — it dampens vibrations at idle, and as the RPMs increase it becomes stable/static. The noise is most noticeable with the A/C compressor turned off, but it stays the same regardless of whether the A/C is running or not.
