Xbox "phase-change interface material"?

post #1 of 6
Thread Starter 
This quote from a Wired review of the new xbox caught my attention. I haven't found anything else referencing how this cooling system works, does anyone know?

As PC gamers know, though, the more horsepower you’ve got under the hood, the more heat you generate; the more heat you generate, the more airflow you’re going to need to dissipate that heat. Usually, that is going to come from fans, but the engineering team kept things quiet by shrinking a number of internal components for better airflow within the console. Allow me a few sentences of total geek-out on this: A new 500-GB hard drive was designed in-house, likewise a custom-built Blu-ray–capable optical drive. A single 40-nanometer chip contains both the CPU and GPU rather than the two dedicated 90-nm chips needed in the 360. In fact, a custom SOC (system on a chip) module made by AMD contains the CPU/GPU chip, the memory, the controller logic, the DRAM, and the audio processors, and connects directly to the heat sink via a phase-change interface material. Whew.

It's definitely a heat pipe, not a huge deal to your high end PC coolers, but compared to most console heatsinks that's a pretty big step up.

The last refresh of the 360 had a heatpipe equipped heatsink

Could also be a vapor chamber heatspreader. Such as the ones found in Sapphire Vapor-X coolers.
