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.
