Zalman announced its latest high-end CPU air cooler, the CNPS12X. This beast was first shown to public at this year's Computex trade-show, back in early June. Between then and now, the CNPS12X got some important retention module changes that make it fully compatible with the upcoming LGA2011 socket on which "Sandy Bridge-E" Core i7 processors are based, as well as AMD AM3+ and FM1. Measuring 151 x 132 x 154 mm (L x W x H), and weighing exactly 1 kg, the CNPS12X uses a design that's essentially identical to that of the NH-D14 from Noctua, that of two fin stacks. It's just that the stacks here are somewhat circular in shape, and that the CNPS12X uses three fans: an intake (before the first stack), a conveyer (between the two stacks), and an exhaust (after the second stack). All three fans are 120 mm in size, and are illuminated by blue LEDs.

The fans seem to be using 3-pin (voltage) method of speed control. Supplied with the cooler are three RC5 intermediate resistors, which make the fans spin at speeds between 850 and 1100 RPM with as low as 22 dBA noise output. Without the RC5, the fans spin between 950 and 1200 RPM, with at least 24 dBA noise output. The heatsink is made almost entirely of dark nickel-plated copper, with certain aluminum parts. Heat is conveyed to the two copper fin stacks by six nickel-plated copper heat pipes, that make direct contact with the CPU at base. Zalman did not give out pricing and availability information.
