I also suspsect that the community is not ready to transition to liquid-cooled systems. I rather assumed 'at room temperature' implied a standard heat sink and fan. Perhaps there's not enough information in that article to draw a conclusion from. There are a few bits that folks

Once upon a time, Warren Kumari [EMAIL PROTECTED] said: Nope, all this says is that with sufficient cooling you can go faster. What we need is going faster with less cooling. Read the article, not the headline. They got 350GHz at room temperature (which is a lot more interesting than 500GHz

The point that I was trying to make (admittedly REALLY badly) was that this is not the 'next big thing' . Did you read anything more than just that article? IBMs press release is here: http://www-03.ibm.com/technology/news/2006/0620_frozen_chip.html and they have a video here:
