Xirex Intros new HD 2900 XT Compatible Water Block

Salzgitter, 15.08.07 – XIREX Stealth 2900XT Waterblocks are available starting from Friday, 24/08/07. Please find here below some highlights of the product:

* The waterblock belongs to the family of "full video-card watercoolers", dissipating the heat produced not only by the GPU of the video card, but also from the ram modules and the mosfets. The waterblock follows the reference design for Nvidia coolers, being attached to the video card using all installation holes, thus not bending the pcb of the video card as competitors' similar products.

* The superficial treatment is done through powdercoating in two different phases (preparation of the surface with industrial micro-sandpapering process and later high quality industrial powder-coating), leaving the surface scratch-resistant.

* The contact area of the waterblock with the GPU chip is trated with the same industrial micro-sandpapering technique to optimize heat exchange through the thermal compound, adapting to the surfaces in the best way possible. This treatment was adopted after comparing lapped surface against micro-sandpapered surface: the test showed that there is no significant difference between the two superficial treatments as regarding to heat absorption. This also reduces production cost, allowing the product to hit the market with a lower price than competitors, yet still with high quality and top performance.

* The waterblock mounts a spacer in the bottom part to "copy" the video card, so to cool perfectly well and at the same time GPU, ram modules and mosfet chips. The thermal interface between the spacer and the base of the waterblock is high-quality thermal adhesive paste, allowing fast heat transfer from the spacer to the waterblock body.

* Fittings are screwed to the waterblock body via brass nickel-plated connectors, which is soldered to the waterblock body. This unique technique eliminates any probability of leakage in such a critical area, as it could happen when using connectors installed with screws and o-rings. The soldering allows also a higher resistance to torsion when installing the fittings, avoiding the thread to be damaged as it may happen to acrylic fitting connectors used in similar solutions by competitors.

* The waterblock is CrossFire-READY. Included are two sealing plugs for stand-alone solutions. When installing a secondary videocard with this waterblock, it is only necessary to unscrew the sealing plug and install the preferred fittings. Fittings can be installed on both sides of the waterblock, allowing a perfect adaptability of the liquid coolers to any existing liquid cooling system.

* All waterblocks are pressure tested up to 3 bars (43.5 PSI) to avoid any possibility of leaks during normal use. The complete absence of o-rings in the design of the waterblock allows a greater reliability of the product in its whole.
