Peter, You are correct that some of the 9672's had "water cooling". It started at the top of the range (cannot remember which model). If I remember correctly it was used for all models on later ranges. I could find out if anyone wants to know. I put "water cooled" in quotes because it depends what you mean. There is the case of a water enclosed system that chills the air before it is passed over the CPU s. This can be called water cooled, but no water passes to the CPU packaging. This is what appeared in the 9672's. This compares to the old "water cooled" processors, like 3090's, where the water actually flows through the CP module. I am not aware of anything like this being used on the latest processors. It depends if you would really call the first a water cooled system. The rumour needs to be clarified on what exactly they are implying. If I have time I will research and give the full picture.

Didn't remember if the latest 9672 also had MCU's but a quick search showed that at least some of the 9672 G5 and G6 models also had a "closed loop liquid cooling system". -- Peter Hunkeler Credit Suisse ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
