Processor cooling innovation may eliminate computer fans and save billions

Principal is much like air cooling heatsinks we have now, with a coolant known as "Fluorinert FC-72"

Passive cooling
Another interesting piece of the puzzle is that the entire system is passive -- no electricity is used to cool the processor in the test computer. Passive cooling is possible because of the excellent heat-transfer characteristics of Fluorinert FC-72. The following steps explain how the processor is cooled using FC-72.

1. Heat from the computer processor vaporizes the Fluorinert liquid.
2. The vapor being lighter moves upward to the heat exchanger.
3. The FC-72 transfers its heat load to the exchanger, which in turn transfers the heat to the surrounding air.
4. Removing heat causes the FC-72 to condense into a liquid that flows into the holding tank below the heat exchanger.
5. From the holding tank, the liquid FC-72 travels to the processor where the cycle is repeated.

The system has successfully cooled Intel Pentium 4 and Core i3 processors.

The Principal is Exactly the Same as Current Heat pipe Coolers
They only need fans to extract excess heat to make them cooling efficient

Old Tech refreshed with no doubt a high price premium

this is nothing new ... 3M demoed novec several years ago
its very expensive ... like 100.00 a liter
and woohoo it cools a pentium 4 and a i3
not impressed

I'm Sat here looking at a Ati Radon X1650 heat pipe Silent edition graphics card and there i am wondering where is the cooling Fan

Am i Missing something

Oh look Fan less Cooling from 2007

Cool. I'd use one once a commercial product is produced.

please don't post anything related to that scamida non-sense the less publicity these ass-hats have the better

I do have my doubts, as this is the same principal that heat pipes operate under now. Something still has to remove the heat that has been transferred to the fins. That's what the cpu cooler fan is for. There has to be phenomenal airflow if you're going to depend on a passive heatsink for a high end cpu. Otherwise, all that heast just stays pooled around the heatsink.
