Announcement probably in June. EDIT: added Dow Jones newswire piece... Fuscaldo Of DOW JONES NEWSWIRES NEW YORK (Dow Jones)Shares of Advanced Micro Devices Inc. (AMD) rose 10% Tuesday after Eric Ross, an analyst at Thomas Weisel Partners, said the chip maker will announce Dell Computer Corp. (DELL) as a customer for its new Athlon 4 chip unveiled Monday. In a research note Tuesday, Ross said AMD will make the announcement in June during Computex Taipei, a computer trade show in Taiwan. AMD spokesman Ward Tisbale said the company does not comment on "speculation and rumors." Dell spokesman Mike Maher also said the company doesn't comment on speculation. He did note that Intel Corp. (INTC) has "met our needs" and that Dell will continue to do business with suppliers whom customers are requesting. Shares of AMD, Sunnyvale, Calif., were recently up $2.80 to $30 on volume of 6.2 million, compared with average daily volume of 9 million. (MORE) DOW JONES NEWS 051501 03:22 PM

Liquid cooling for CPUs with Fluorinert baths Jozef Halada writes: "Anyway, since I am still 40C below max die temperature, even when the CPU is heavily loaded, I don't see a reason to use higher performance CPU fan (and get more noise as a result)." I'm surprised no vendor is making the jump to liquid cooling, especially for multiprocessor systems where each CPU is a high-watter. No, this _doesn't_ have to be water-cooling. Liquid flourocarbons, e.g., the Fluorinert variants like FC-77, are non-corrosive and can contact the CPUs and even the entire boards. (We used to do our thermal shock testing with Fluorinerts, made at that time by 3M, and even did some burn-in testing of running memory boards inside Fluorinert baths; these may even be standard by today for all I know of current practice.) The Cray 2 supercomputer uses a Fluorinert bath to cool the processor(s). Very exotic-looking, the one I once saw at Lawrence Livermore. The CPUs in a bubbling bath of shimmering liquid. How might a vendor do this? Making a bath large enough to support the entire machine is possible, but would interfere with "other uses" :-). Could only the motherboard be immersed? Not with current designs, obviously. A potential downside is the weight of the immersion cooling bath. Depending on how much fluid is used, could make a machine 20 pounds heavier. Not a concern for certain servers, big concern for laptops, obviously. A way to amortize the entire weight, and design, issue might be with the "blades" approach now gaining favor. The thin blade plug-ins, resembling the old CAMAC crates of the 70s and 80s, could just about as easily be Fluorinert-cooled instead of air-cooled. Is it a long-term solution? I think so. CPU power dissipation is trending upward, despite new processes and lower voltages. On-chip refrigeration or heat pipe disspators fits with current motherboard design. But at some point it may make sense to use full immersion cooling. By the way, even a small Fluorinert cooling system could be quite a sexy design. Maybe this is more for a Steve Jobs, Apple-type of system. Take the Mac Cube and imagine a bubbling bath around dual or quad CPUs. Just a thought. --Tim May (finally got National Discount Broker to process my app and thus give me my SI "official Stocktalk posting privileges")
