BMW X5 Fan Noise

I have this very annoying noise coming from my A/C and have no idea what is causing it.

Here is a video showing the noise.

Does any one know what could be causing this? Thanks

One likely culprit is the blower motor -- they had to replace my blower motor due to noise a few months ago at around 37,000 miles. Does the frequency of the noise change with the blower speed?

Yea I think the frequency does change when I increase the blower speed.

Does this mean I need to replace the blower motor? Also any idea of what this would cost since I am out of warranty? Thanks

I had to have the blower housing replaced. Was blowing hard after the engine shit down.
