Not long time since the first air coolers for Core i7 showed up, German water cooling expert aqua-computer has decided to let us know that some of their high-end cuplex series CPU waterblocks including the cuplex xt, cuplex xt di and cuplex hd are now also available with conversion kits/mounting brackets to suit Core i7 LGA 1366 sockets. The Cuplex XT series is one of the best CPU blocks offered with an attractive look and 100% German build quality. It is made out of two parts, a high-quality copper base, and a translucent blue acrylic top. The Cuplex XT fits only G1/8 threaded fittings, a G1/4 version is also in the works.
