Corsair has announced a new pair of entries in its Hydro Series sealed-loop watercooling rigs which pack vital extra inches for those whose cases can take the load.

The Corsair Hydro Series H90, to start, features a square 140mm radiator fitted as standard with a single 140mm static pressure fan, compared to the 120mm radiator and fan used in the H80. The result, Corsair claims, is improved cooling from the extra surface area of the larger radiator and reduced noise from a slower-spinning fan that can nevertheless shift the same amount of air.

For those with more heat to shift, the Hydro Series H110 doubles things up to a 280mm by 140mm rectangular radiator fitted with a pair of 140mm static-pressure fans side-by-side. Again, Corsair claims improved cooling at lower noise levels that its last-generation Hydro Series H100 version, which used a 240mm by 120mm radiator with a pair of 120mm fans.

Both models include a revised cold plate design, constructed again from copper but offering a claimed improvement in heat transfer compared to the design used in the H80 and H100 models. Both are supplied with fittings for Intel socket LGA 1155, 1156, 1366 and 2011 and AMD socket AM2, AM3, AM3+, FM1 and FM2.

With the radiators taking extra room, however, cramming the new models into your case may be a struggle: Corsair advises that the H110 will fit in the top of cases that have dual 140mm fan mounts with a 20mm screw spacing, while the smaller H90 should be compatible with any case that has a rear or top 140mm fan mount.

UK pricing for the new coolers has yet to be announced, with Corsair setting US recommended retail prices at $99.99 for the Hydro Series H90 and $129.99 for the larger Hydro Series H110 (around £63 and £82 respectively, excluding taxes.)
