I've had my Alienware Aurora for just over a month. However recently (in the last days) has begun to make a strong enough noise / buzzing noise. It sounds almost like a kind of small appliances. The noise appears to come from the back of the machine where the fan or liquid cooling system is. Noise does not always but most of the time. It's really annoying and quite annoying. Does anybody have any idea what possibly will be causing this noise and how to fix it?
