It's quite an interesting one this. It seems that Denmark based Danamics have developed a CPU cooler that makes use of "liquid metal", which is claimed to have cooling performance that exceeds most water cooling systems. The liquid metal (whose composition details are scarce) appears to be contained in heatpipe like tubes, which I assume is then circulated using the integrated multi-string electomagnetic pump. Being electromagnetic means no moving parts, as well as a low power requirement (less than 1W apparently). The cooler, named the LM10 certainly sounds as though it has potential on paper, but we'll reserve judgement until someone gets their hands on one and tests the performance. Pricing and launch date are unavailable at this point (naturally).
