Sounds like a bad bearing in an idler, or one of the accessories, or a worn-out fan clutch. Don't drive it until it's fixed. The bearing could seize and cause more damage.

I'm replacing the fan clutch today to see if thats it

Be sure to examine the idler wheels and accessory bearings by spinning them, looking for noise.
