"Only a few days have passed since the introduction of the new low-cost but highly efficient phase-change cooling system aka Mach II ST. But already now, on ASUS booth at CeBIT you could see one more Mach II modification from nVENTIV at work.
nVENTIV Mach II GT is positioned as a high-end solution, which performance is the key factor determining the users’ buying decisions. Mach II GT has no performance issues to worry about. The thermal characteristics of the new system are unprecedented for the mass products of the kind. In fact, you can only achieve better results if you use specially designed cascade systems or vapor cooling (with liquid nitrogen or dry ice). The vaporization temperature is around -65C (under 0W workload), which is 15 degrees better than the results shown by Mach II. The temperature under maximum workload of 200W have also dropped proportionally: the vaporization temperature is -40C, while the CPUI surface temperature equals to -20C."
