Both the fans of my Inspiron 9300 make a lot of noise. Previously in order to reduce noise I tried to completely remove the fans and cleaned them with compressed air. At that time I found it weird that they did not make much noise when they rotated (pretty fast) because of the compressed air. The fans keep making the same amount of noise. I notice that if I apply some pressue next to the keyboard where the fans are located the noise emitted changes.
So, my question.. are the motors themselves making the noise? Or is it that the vibration caused by the motor making the fan to rattle against other parts of the laptop? If its the second I could try to fix the fans more securely. I have not been able to get any replacement fans hence this question.
