Possible Causes

Loose fan blade, Foreign object contacting fan, Worn fan motor bearings, Loose mounting screws on fan shroud

Safety first: Turn off power and wait for the fan to stop completely before inspection.

Inspect inside cavity: Remove racks and check the rear fan cover. Remove the cover to inspect the fan blade for bent fins or foreign objects.
Tighten blade: Ensure the fan blade nut or screw is tight on the motor shaft.
Check bearings: Spin the fan by hand. If it feels rough or wobbly, replace the fan motor.
Secure shroud: Tighten any loose screws on the fan shroud or rear panel that may cause rattling.
