Fan should be replaced from time to time. Normally I do this when they are getting too noisy.
I work setting up CCTV systems and DVR-CCTV boxes all the time. I have tried putting some oil on fans when they become too noisy. However I find myself doing this every six month or so. Where as just replacing the fan should give me 2 years with out any hassels.
