When it comes to computer processors, the advantages of a die-shrink are undeniable. For chip makers – and overclockers – a processor manufactured at a smaller process can open up more headroom for faster clock speeds, or decrease power consumption and cooling requirements. A die-shrink is a much-lauded happening in the computer world. For consoles, however, a die-shrink usually occurs without much fanfare – except in the case of the Xbox 360. Gamers have been waiting for months for the arrival of 65nm Xbox 360 chips, with the hope that the cooler-running processor would mean more stable hardware.

Microsoft’s latest console may be home to some of the best software, but in terms of hardware, the Xbox 360 is commonly thought to be unreliable. DailyTech uncovered in July a defect rate as high as 33 percent for all Xbox 360 consoles. Just days after the report’s release, Microsoft extended its warranty coverage of the Red Ring of Death defect to three years.

Although Microsoft refuses to tell the public what the main cause is of the failing hardware, but most point to inadequate cooling of the 90nm graphics processor. Evidence of this came when users reported of receiving both new and repaired machines that featured a new heatsink design intended to better cool the GPU.

Aside from introducing improved cooling, Microsoft was also in the process of moving its 90nm chips to the 65nm process. The first hardware revision to implement a 65nm chip was codenamed “Falcon,” and consoles featuring the new design are hitting store shelves now, according to consumer discussion on the official Xbox forums.

A brave individual with the Gamertag “JWSpeed” dissected his new Halo 3 Special Edition console to discover inside a new, simplified heatsink design. Upon further inspection and the removal of the heatsink, a new CPU branded with a “CANADA” label rests on the motherboard.

The new heatsink design does away with the heatpipe, indicating that the cooling requirements of the new chip are less intense than of the old design. For reference, the console examined to have the new hardware was built on August 24, 2007 from team “FDOU” and lot number 734. Those interested in learning how to tell if an Xbox 360 console features the new chip without voiding the warranty should refer to a guide from the Xbox forums.

Strangely, the chip that makes the move to 65nm in “Falcon” affects only the CPU, rather than the trouble-causing GPU. Of course, making the CPU at 65nm is also a cost-cutting measure for Microsoft, as the chip will be smaller and 50 percent less expensive to manufacture. Without moving the GPU to 65nm, however, it is impossible to know if the new “Falcon” models are still at risk of the Red Ring of Death.

How many months till it would reach premium SKUs?

Also would it run noticeably cooler? Cause my 360 pretty much heats up my TV room in the basement. Temperature goes up like 5C after an hour.

LOL,
I don't know if your intentionally trying to be funny, but your TV takes far more power than the Xbox.

His TV might draw more power but that doesn't mean it outputs more heat.

My Xbox doesn't run really hot but it does heat up my living room a little. Sometimes I'll turn the fan on high. But other than that I don't have to do anything. Once it gets colder it'll be a feature, not a problem. ;)

And where do you think that TV power goes?

Electronic devices convert almost all of thier drawn energy into heat. TV's do convert some energy into light, but the vast majority is wasted.

Still, you'll find that most TV's (especially CRT's) take more power, and hence emit more heat.
