Intel chips get hotter

Some choice articles from the enquirer...

Apparently, the new dual core Montecito chips from Intel are going to be a bit toasty - like 150 W. Looks like the stock heatsink is going to come with a couple of large peltiers - only way to keep the thing from burning up apparently.

That doesn't make sense to me. The peltiers will just pull a whole lot more power themselves. That doesn't sound like a viable solution.
 
I read somewhere in the dual opteron will be incredebly similar to the single core in terms of power output. AMD claim it will still come under the 89w (i think) limit they set on the whole A64 line. Which is a good thing.

Yep, seems unlikely. The CPU + dual 100W pelts would be over 500W assuming ~60% efficiency. Perhaps they plan on having two of THESE blowing across that radiator...

sweet fans. i like how the noise column is blank. the peltiers don't make sense. they said the problem was there being a lot of heat produced in a confined space, which means you upgrade the cooling system, not add more heat as the peltiers do. the peltiers will double the heat produced, not get rid of it so that crappy heatsink will work...
you would probably have to watercool the hot side of those peltiers to keep them reasonably cool, or just put a monster heatsink and 4 highspeed fans in push-pull.
 
I remember seeing some type of micropiped water cooling solution Intel was investing heavily in. It would need only a very small amount of water and a small heatsink and little power, but could cool like 200w+ since it propelled the water through these tiny pipes in the heatsink and it was voltage driven somehow.
 
Apple's cooling on the new G5s is NOT liquid cooling like your thinking. Its more of a heat pipe, like what can be found in most SFF PC's and many laptops.

Wrong. The Cooling on the Apple G5s absolutely is a conventional 'liquid cooling' system using a water/propylene glycol based coolant which is pumped around with an electric pump. To minimize noise, the OS controls the speed of the fan and the pump, slowing them down when maximum performance is not required.

It is not at all similar to a heatpipe cooler.
