Bad fan motor... Did you get a warranty?
If so, take the computer back and ask for a new fan.
If not, then buy a new fan as soon as possible, and do not leave the machine powered on when you are not sitting right there. If that fan stops, your CPU may be completely destroyed in seconds. New fan: ~ $7.00. New CPU: ~ $350.00. And that's assuming that no other damage is done...
