Most likely the fan is out of balance (most likely from having a loose screw). I had the same problem with me but it was worse cause I stuck a screwdriver (a thick one I might add) into the fan while it was spinning (cause I was curious lol) and it took off one of the blades >_<.

wait.. is this the processor fan above the CPU heatsink (dont use scotch tape here)? or the case fans?

check the RPM of the fans in Bios's Hardware monitor or other monitoring app, and also the temps and voltages as well..

clean out any dust especialy those dust grills on the pc with an air compressor or vacum cleaner..

on very rare occasion, a ball bearing in the fan may be cracked. it won't cost much to get a new one (fan). just make sure it fits ur heatsink

one of the blade maybe heavier and causing the vibration, can check for balance by using a penknife to scrape a little material off to balance or put a tape.
