your fan probably has a liquid bearing. if it is constantly noisy when it runs the bearing is dried out. you should take the fan out of your laptop and use some silicone spray on the bearing to make it wet again.

if taking away the dust only makes the fan work les often, but doesnt help with the noise it makes when it runs, your fan probably has a liquid bearing. if it is constantly noisy when it runs the bearing is dried out. you should take the fan out of your laptop and use some silicone spray on the bearing to make it wet again.
