New fluid invented for immersion overclocking Semicon West 2006 Galden probably not meant for thisBy Charlie Demerjian: Wednesday 12 July 2006, 06:36 OVERCLOCKERS ARE AN odd bunch, and tend to evoke terms usually used in conjunction with mad movie scientists. Strangely, it is because they tend to be mad scientists. One of the things you read about now and again is attempts at fluid immersion, and on top of that, fluid immersion with extreme cooling. I ran into a new toy for those attempts at Semicon today, a fluid called Galden.The company that was showing it off, the Kurt J. Lesker Company also sells it, so mad scientists take note, you can actually buy this stuff. There are a range of fluids in the Galden family, mainly differentiated by boiling and pour points. All are non-toxic and don't burn, a notable drawback compared to one of its competitors.The working range goes from a high of 250C for the HT270 fluid to a low of -90C or so for HT70, with a pour point of -110C. With this stuff, you can cool your whole board down to almost 100 below, and still see it. CPU and GPU cooling? That is for the uninspired.So, with this gauntlet thrown down, I should warn you that this stuff is not cheap. It sells for around $350-400 a gallon, but if you want an ultra-cold system in an aquarium, you don't have many choices, much less cheaper ones. Send me the results of your experiments guys. µ
