Looks like NZXT has Corsair a little worried... Corsair has just released a set of single 140mm fan and double 140mm fan watercooling systems called the Hydro H110 and Hydro H90 to compete against NZXT's Kraken X40 and X60 watercoolers. Here's the full PR.
Corsair®, designer of high-performance PC hardware components, today
announced the Hydro Series™ H110 and H90 liquid CPU coolers. With huge radiator
cooling surfaces areas of 280mm and 140mm respectively and specially designed
140mm low-speed, high static pressure fans, the new coolers deliver superior CPU
cooling and quieter operation than smaller 120mm designs.
The Hydro Series H110 is a low-noise, high-performance liquid CPU cooler with
a double-length 280mm by 140mm radiator. The H110 radiator's large surface area
provides more contact room for heat dissipation and for side-by-side mounting of
dual fans. Each fan is a specially-designed low-speed 140mm static pressure fan,
which moves much more air per decibel of noise than 120mm fans. Combined, the
larger radiators and lower fan-speeds produce better performance with much lower
noise levels than smaller 120mm dual-fan coolers. The H110 fits cases with dual
140mm top fan mounts and 20mm screw spacing.1

Hydro H110
The Hydro Series H90, like the H110, is a low-noise, high-performance liquid
CPU cooler, but with a more compact square 140mm radiator and a single 140mm
static pressure fan. The large radiator and spacious surface area combined with
lower fan-speeds produce better performance than smaller 120mm single fan
coolers with lower noise. The H90 is compatible with many cases with a rear or
top 140mm fan mount.

Hydro H90
The Hydro Series H110 and H90 liquid coolers feature an enhanced copper cold
plate with soaks up heat more efficiently than previous generation designs. Both
coolers are compatible with most modern CPU platforms including AMD AM2, AM3,
AM3+, FM2 and FM1 and Intel LGA 1155, LGA 1156, LGA 1366, and LGA 2011.
"Many PC enthusiasts choose liquid cooling for its extreme cooling efficiency
and quiet operation," said Thi La, Senior VP and GM of Memory and Enthusiast
Component Products at Corsair. "To take liquid cooling the next level, we
super-sized the Hydro Series H110 and H90, providing users our best
cooling-to-noise ratio ever."
Pricing and Availability
The Corsair Hydro Series H110 and Hydro Series H90 liquid coolers are
immediately available from Corsair’s worldwide network of resellers and
distributors. Suggested retail prices in the United States are $129.99 for the
H110 and $99.99 for the H90.
