After a pretty long period of inactivity, liquid cooling specialist Alphacool has released two new water blocks for Nvidia GTX 580/GTX 570 and AMD Radeon HD 6970/HD 6950 graphics cards. Both of these solutions belong in the NexXxoS product line and feature a similar design.

The two NexXxoS water blocks cover the whole printed circuit board (PCB) of the card and Alphacool has designed them so that they would cool not just the GPU, but also the memory chips and the VRM circuitry.

As a result, no additional airflow has to be directed towards the system's graphics cards as the water blocks should be able to keep the temperatures in check without any problems.

The thin design also enables users to install two or more such GPUs in CrossFireX or SLI for added performance.

According to the company's website, both NexXxoS water blocks measure less than 5mm at the contact points and their weight is set at about 1Kg. As a result, Alphacool designed some special backplates that should help stiffen the graphics card, which are priced at 13.50 Euros.

As far as the prices of the two water blocks are concerned, the NexXxoS ATXP, for AMD Radeon HD 6970 and Radeon HD 6950 GPU, is priced at 64.95 Euro, while the GTX 580 NexXxoS NVXP comes in at a slightly higher 69.95 Euros.

The liquid cooling blocks are sold together with all the required fittings, various thermal pads, a tube of thermo-conductive paste and an installation manual.

In addition to the NexXxoS blocks, Alphacool has also announced the availability of the watercooled Silentmaxx FANLESS 600W power supply unit, which retails for €219.99.

Just as its name implies, the PSU can deliver 600W of power and it features two 22A 12V rails as well as an 89 percent energy efficiency rating. (via HardwareLuxx)
