Had fan noise from both left and right fans. It was driving me crazy all the time.
The repair was straightforward, easy to do. I was a bit nervous the moment I turned on the machine, but no need to worry! The machine was quiet and ran smooth. The quiet is a real blessing! Thanks, Ifix it for your true help!
Keep careful track of the screws as you take the case apart.
