How can I fix my laptop?

Make sure that the air vents are clear of any dust and any other obstruction. It looks like there is something loose in the air vents that may, or may not, interfere with the air circulation. The movement and vibrations of transport can cause an object to move in and out of the air flow.

At least, that's how I interpret the intermitent nature of your problem. When the air flow in blocked, the temperature controll causes the fan to run at full speed, causing a high noise level.

You should still check your fan, as it's been put under a lot of needless stress.
