This would be an interesting move. Didn't Intel also look into this cooling solution for their upcoming SB-E chips?
At present AMD is looking at something like Antec Kühler H2O 620 self-contained liquid cooling system. The solution consists of a CPU water block with copper base, large 151x120mm heat-exchanger as well as 120mm cooling fan with 1450 - 2000rpm speed. The product - which was developed in tandem with well-known LCS specialist Asetek - can be easily installed into almost any modern computer just like any other cooler and the only condition is presence of a place to install a 120mm fan. The Kühler H2O 620 is claimed to be 20% more efficient compared to stock coolers. Naturally, AMD may order a different LCS or customize the 620 model.
Inexpensive sealed liquid coolers cost from around $60 to around $70 in the U.S. retail, which means that it is completely possible to bundle it with chips that cost $300, $400 or more. Such microprocessors are usually bought by enthusiasts who usually overclock their chips and included LCS allows to do it easier and safer. Furthermore, bundling self-contained liquid cooler with a CPU will attract attention to this CPU and the brand. On the other hand, inclusion of such unusual cooling solution may indirectly indicate that AMD needs something extraordinary in order to attract attention and boost competitive advantages of its FX-series chips code-named Zambezi.
AMD itself believes that its multi-core Zambezi FX CPUs will allow it to compete head-to-head with Intel's high-end Core i-series "Sandy Bridge" processors that can sell for as much as $300 and more per chip.
