2007-07-25Annonce officielle des waterblocks XIREX
Voici le communiqué de presse du waterblock pour les GeForce 8800GTX de Xirex que je vous ai présenté hier.
- 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.
