Noisy fan on Ubuntu 14 04 ATI Radeon 7000 series [closed]
Solution 1:
Consider the possibility that there is a hardware issue with the noisy fan and therefore the problem is not a bug or reproducible as a software issue.
If a computer fan is making an annoying noise, it is often also the case that the computer is running hotter than it needs to run due to a mechanical problem with a worn out fan. Replacing the fan not only eliminates the noise, but may also lower your computer's temperatures because the replacement fan may also run faster in addition to running more quietly.1
