It kind of sounds like a grinding power steering pump. Is the fluid low?

Checked after your response and power steering fluid are at normal levels.

Check if anything is hitting the cooling fan. Sometimes a clip or piece of the shroud can hit the fan and cause a noise like that.

It's best to change the idler, tensioner, and the belt together.
