Apple could use water-cooled PPC to boost MHz

Apple/IBM could soon been shipping to boost clock frequencies without putting extra strain on notebook, desktop and server heat management systems, courtesy of a new technique developed by Stanford University spin-off company Cooligy, according to The Register: "Cooligy's approach - called Active Micro-Channel Cooling (AMC) - involves scoring hundreds of tiny channels into a silicon layer placed on the upper surface of the chip package. Water - or any other fluid, for that matter - circulates through the channels drawing heat away from the core. The company claims AMC can cool a CPU by up to 1000W per square cm. The best a passive system can manage, it says, is 250W per square cm."

    Check the water level in that laptop.

    Uh...

    Where does the excess heat go?

    It's a hack ...

    ... and bad editing. The company hasn't signed an agreement with anyone, and could easily make this technique for Intel/AMD instead of or in addition to Apple/IBM.

    I'd be VERY leery of overclocking a chip and then relying on a water-based cooling process until it had been THOROUGHLY tested by independent sources. About 1/4th of the dead computers my local repair depot see are PCs where the owner attempted to overclock (with any number of bizarre methods to cool the machine).

    Simple

    Here is what they are doing. They score the top of the traditional chip package. Attach their patented water chamber and micro pumps to it to give the chip an effectively larger surface area so that traditional fan/air methods work off their water radiator.

    The CPU up till now has been air cooled like WWI airplanes. Now they are trying to get something that can move heat closer to the heat source - Just like a car.

    The heat has to go somewhere and it is most likely still into your lap. Only now the system can move more heat.

    The Register...

    The Register is widely known as a rumor site (about as bad as mosr). This is hardly news.

    Like Car Radiator...

    Will we need to add antifreeze for freezing/corosion?
