Macbook pro 2010 fan makes very loud noise
I notice when I'm working my fan starts making a louder and louder noise. When I look to see the RPM speeds on the dashboard, I can see that the Right fan speed drops below 2000 to about 100-300 (left fan speed is about 2000). The noise goes on for about 2-3 minutes then the right fan'speed jumps back up to 2000 and the noise is gone.

Id suggest that you make sure you don't have debris clogging the vent ports. Apple's vents are between the display and the lower case. They're kinda hard to see so put you monitor down as flat as it will go like 180 degrees away from the bottom case and turn it around. If its dirty you cab try to clean it with compressed air or canned air, but its best to open it up and blow it out of the machine not in. Do a youtube search if you're not aware how to take it apart, and you probably should have to take off more than the bottom cover. Good Luck!
