For a pre-built PC or laptop, I don't think it would be unreasonable for the customer to expect the manufacture (in this case Alienware/Dell) to have taken care of all that. People shouldn't overclock or alter the hardware unless they know what they're doing, but by just using a pre-built PC for the purpose it was designed for to then have it suffer from cooling issues, that blame falls on the manufacturer, not the person using it.
