The folks over at Hexus in the UK have an interesting article up discussing water cooled computers and if it is here to stay, or just a passing fad - as they put it. If you're considering water-cooling your precious innards and maybe a little apprehensive about the thought of water flowing around inside your case, make time to read this article.
After installing the WaterCooling I soon found that the temperatures had changed from the previous Zalman flower setup. The CPU temp had gone down as expected, in actual fact they had dropped from 62c with the Zalman to just 47c with the WaterCooling. I am more than happy with a 100% load temp of 47c.More information @ Hexus
