  My new Alienware laptop has some problem with the fan, the fan keeps turning on and off, even when I did nothing. The fan will suddenly turn on for 1 sec or 2 and immediately shut off for 3-4 sec and turn on again, repeat. the fan is not running full speed, and it is not very loud, it is just very annoying, especially when you are working beside it. I know I can turn the fan off in the AWCC, but it is annoying to keep adjusting it. Is anyone else having the same problem?
