Product Description & Info
The MCW82™ waterblock is a Universal GPU cooling solution designed for
today's high-end graphics processors. It uses the same advanced 0.25mm pin
matrix as it's predecessor, the MCW80 (similar to the award-winning Apogee™
XT CPU water-block), and features an improved hydraulic design resulting in
substantially reduced pressure drop compared to the earlier generation. The
block is capable of dissipating the highest heat loads (hundreds of watts)
with extraordinary efficiency even at low to moderate flow rates.
In addition to superior GPU cooling compared to any other solution on the
market, the MCW82 is also future proof since it retains the same form factor
as its predecessors the MCW60 and MCW80. As such it is compatible with most
reference design graphic cards (as well as many non reference models),
thanks to a host of adapter brackets legacy of the MCW60. New bracketry is
updated on an ongoing basis as new graphic cards come out.
As most of today's high end graphic cards also necessitate active cooling
for the power and memory components, Swiftech also offers two different
solutions to cool these devices:
- Full cover heatsinks are available to cool the most popular
reference design models. These low cost heatsinks are compatible with
the MCW80 form factor, and as users upgrade their graphics card, they
can retain the MCW80 while only replacing the heatsink
- Individual ramsinks such as the MC14 are another convenient method
to cool surface-mount components in non-reference models or for those
models that are not compatible with the full cover heatsinks.
Features and Benefits
Superior thermal performance compared to "full-cover" solutions
- Because the cooling solution is specific to the GPU module, it is not
mechanically dependant of other thermal joints compared to full-cover blocks
that must also cool memory and VR's. As a result, the GPU thermal joint is
always optimal;
- Same cooling engine as the Apogee XT: 0.25mm x 0.25mm micro pin matrix;
Moderate pressure drop specifications
As can be seen in the performance section, the MCW82 is close to its early
predecessor the MCW60 in terms of pressure drop specifications
Minimum pressure drop when setup in parallel in SLI or CrossFire configurations
- Hydraulic performance: contrarily to popular belief, setting up 2
restrictive blocks in parallel is a vastly superior solution to setting up
in series; in theory (i.e. without acounting for fittings) fluid mechanics
show that the pressure drop of 2 of the same blocks setup in parallel is
1/4th that of a single water-block. By contrast, the pressure drop of 2
blocks in series is twice that a single block; it follows that the pressure
drop of 2 blocks in parallel is 1/8th that of 2 blocks in series. In
practice though and when accounting for fittings, the pressure drop of 2
blocks in parallel will fall to approximately 1/4th of 2 blocks setup in
series.
-Thermal performance of water blocks in parallel vs. series was also
demonstrated in this
white paper.
TThe block is compatible with most reference design graphic cards (as well as
many non reference models), thanks to a host of adapter brackets. New bracketry
is also updated on an ongoing basis as new graphic cards come out. As a result,
it is likely that you will be able to keep your MCW82 next time you upgrade to a
new graphics card.
Performance Data
Thermal performance: Improvement compared to the MCW60 is comprised
between 1.5 and 4°C or more depending on GPU's and heat loads.
