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.
