XIREX releases Ultra Thin Series of VGA Water Blocks


Xirex is launched a wide array of new products, most remarkable are their VGA water blocks which cover both GPU and MEMORY chips of the VGA cards, the total height of the VGA block is also kept to a minimum allowing for easy SLI/CF setup. They have blocks for 8800 GTX/GTS and the ATI R600 series. Their first commercially available block will be for the 8800 GTX and it's on sale at the end of the week (XIREX Nvidia 8800GTX Waterblocks are available starting from Friday, 27/07/07.)
# 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. This solution, furthermore, allows producing waterblocks using only one waterblock body and different spacers for GTX/ULTRA and GTS video card versions, reducing significantly production costs and thus end user price.

# 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 SLI-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.

If these blocks look familiar, this might clear up things a bit:

Not to be confused with Rambus. Under the newly founded brand Xirex, these talented lads are currently designing and already manufacturing water-blocks that are targeting best price/performance ratio, and a product or two that will bring unique twist. At least, that's what Xirex is now hoping for.

The gray part from the above picture is approx 4mm thick, count two extra mm for a top covers which will improve the looks of this block.
