Mine has been having the same problems everyonce in a while. It seems to be a temp problem with the fans and, like mentioned earlier, the power cord not being properly seated on the intercooler. After about 5 minutes of running the fans stop making all the noise and are pretty quiet. I've had mine for about 3 months and it started all the noise within the last month. I really don't think it is causing any real problems and like what poeticpyro said, it really helps out when playing oblivion for extended periods of time. Without it I usually freeze up within about 2-3 hours of gameplay.
