The snazzy new Xbox 360 250GB SKU went on sale in the UK today, and TechRadar has been giving it the once-over for the last week or so. You can see the results over at our new Xbox 360 review.

One of the main complaints about the original 360 models was that to watch a DVD or play a game off a disc, you had to contend with tortuous levels of white noise.

You know the story - overheating components meant the cheap cooling fans went into overdrive, and the noise of the DVD drive itself could drown out a Chinook.

Has there ever been a more iconic sound in the gaming industry than the noise of an Xbox 360 firing up its DVD drive in the heat of summer? We think not.
