New cooling system, processors coming to next-gen Macs at Macworld 2009 or later?

According to sources related with the Taiwanese companies that produce Apple’s Macs, the next-gen iMac due early next year will include a new cooling module. Although there isn’t much evidence of this, an article published this Monday stated that Foxconn Precision Components and Auras Technology would supply “the PC’s cooling module” for the new “magnesium-aluminum alloy chassis.” The Mac currently uses a fan based cooling system that may need to be beefed up a little more if Apple does, in fact, plan to include a new quad-core chip into their machines.

Wait, what’s going on with these new chips?
