After putting ECT's awsome little Prometeia Mach II GT though its subzero paces, there's no way we can overlook a round of phase-change overclocking... so after hooking everything up, I pressed the power button and watched the temperatures drop. A few moments later the Prometeia Mach II GT powered on the rest of the computer, and I immediately loaded the BIOS and found that the processor was running at a chilly -27C.
