There are several reasons why your fan may be noisy. For one thing, you may be running too many processes in the background, which causes your laptop to overheat, thus making the fan work extremely hard. You can close some processes to lower the heat generated. Another reason is that there may be dust in the fan. What you can do is get a can of compressed air and indirectly spray it at the fan to blow the dust out.
