There is a slight whirring sound from inside my laptop. However I realized that even if I unplugged the fan, the sound would still exist. I also have a ssd. Is there any non moving part that could generate this sound?

providing the model of laptop might help – Keltari May 4 '13 at 5:08
Could be an extra fan, perhaps on the GPU, or a faulty MB, or some warming/cooling issue - you did not provide enough information to assist... – Traveling Tech Guy May 4 '13 at 6:33

There are some components that can make nose even when they shouldn't:

  • small transformer (like the one in display that create high voltage)
  • relay - they can clicking
  • coil - they can vibrate

But it could be also broken CD-ROM.
