Tiny Bubbles Key to Cooling Crazy Hot CPUs
Smaz writes "With future CPUs expected to generate as much as four times the heat of today's processors, wicking away that heat remains one of the biggest engineering hurdles in the biz. Researchers at Purdue have developed a pumpless liquid-cooling system that removes nearly six times more heat than existing systems. The trick, it seems, is in the tiny bubbles. From the Science Blog."

Laptop burns boffin's penis
November 22 2002
Doctors are warning that laptop computers may inflict a burn even through clothed skin, after the bizarre case of a Swedish scientist who scorched his penis and testicles while writing a report in his armchair.
The unnamed 50-year-old father of two had balanced the computer on his lap while he wrote the report at home, taking about an hour to do it, according to a letter published in the next issue of the British medical weekly The Lancet.
The following day, he started to develop painful blisters on his foreskin and scrotum, which became infected but eventually cleared up without the need for antibiotics.
Laptop manuals usually advise users not to use the computer while its base is resting directly on exposed skin, as heat can build up if the device is left on for a long time.
In this case, however, the patient had been wearing trousers and underpants.
The tale "should be taken as a serious warning against use of a laptop computer, in a literal sense," said the letter's author, Claes-Goran Ostenson of the department of molecular medicine at Stockholm's Karolinska Institute.

imagining a Lava Lamp mounted to your CPU?
you will hard boil an egg rather then fry it on your P12 256bit quad CPU.
darn, all have to get a new recipe book.
Tiny Bubbles
Running WINE
Make me happy
Make my PC feel fine.
Tiny Bubbles
Make me warm no longer
With a feeling that I'm going to cool you
Till the end of time
So here's to the Boilermakers
And here's to Purdue
But mostly here's to a cooler CPU

Happiness is like peeing yourself. Everybody can see it but only you can feel its warmth.
Bubbles? Bubbles of nothing?

They mention bubbles in this article - well, it's common knowledge that bubbles in Guinness defy gravity !
So maybe these chips will be served with a Guinness cooling agent ?
A 500 year old cooling method can't be wrong !
I love my chips with Guinness !
Hic, arrrr
A slashdotting - you get the stick first and then the carrot !
... Microchannel was the way to go.
VAPORware!
yeah, had to say it and couldnt find it said with 1 sec search.

Try this special secret Flash advertisement blocking technique:
# rm /usr/lib/mozilla/plugins/libflashplayer.so
I have found it is capable of stopping all flash advertisements before they even load.
Remeber, it is a secret. So please don't tell anyone.
Money I owe, money-iy-ay
It will be interesting to see if the shock waves from the cavitation (the sudden formation of the tiny bubbles) affects the operation of the chip or erodes the surface, limiting the life.
No, no! It won't be the shock waves that reduces the life of the chip...rather, it will be the hard radiation from the resulting sonoluminescence and nuclear fusion that will undoubtedly occur.
I looked away as I glanced at the first line and read it as "With future CPUs expected to generate as much as four times the heat of the sun..."
:)
I was going to agree... my t-bird 1.3ghz gets daamn hot.
So the heat from the CPU creates bubbles in the liquid... Certainly sounds like a Boilermaker to me!

I'm going to hold out until the inevitable integration with the advanced chemistry found in my Scrubbing Bubbles(r) Bathroom Cleaner.
Then my PC will be heat AND dust free! Less work for Mom!
Today's computers use fans and heat sinks containing fins to help cool circuitry.
That's the problem with today's technology. We keep using Fish in our hardware. No wonder the experts predicted that the smaller the channel, the less heat that would be dissipated (paraphrasing). The fish they were using would not be able to fit though the small channels, thus causing the channel to be blocked!
It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.
This explains why the Star Trek control panels are always exploding. It's not that they routed main power through a switch on the panel, it's that the fancy-assed graphical display needed a terahertz-class processor to render the warp field display in real-time. That last Romulan disruptor blast just dislodged the heatsink for a few milliseconds and {poof}.
Let me guess: they'll sell these high-end servers for only $50. The catch is that they'll constantly consume cooling fluid from insanely priced single-use proprietary HP cartridges. What's worse, the server will come only with a half-filled cartridge.

Oh, and I apologize for my horendous spelling but you don't have to spell to run a nuclear reactor.
Very true, Homer. Very true.
Finally! A dedicated random number generator coprocessor.
Great, now sell me a DIY kit so I can tame this Athlon T-Bird block heater. 50 degrees idle with a 7000-rpm fan.. it's insane!
