Precision 7520 CPU Fan Grinding Noise

The CPU fan on this mobile workstation has started making a loud, grinding noise.  Aside from the noise, the loud fan causes no other issues: no errors, no slowness, etc.


The Dell diagnostic tests completed successfully and passed.  I updated the BIOS to version 1.15.1. 


How can I obtain a replacement CPU fan for this mobile workstation?

It would be cheaper if you could get the part number off the fan.

Then search eBay and Amazon for a replacement.

If not you could replace the whole heatsink.
