Introduction
The MCW55™ VGA waterblock is a next generation
liquid cooling solution for high-end graphics processors. It is
designed to treat GPU cooling as efficiently as the most advanced
CPU water-blocks, in response to the anticipated increase in heat
dissipation requirements for the graphics industry.
The MCW55 waterblock inherits some characteristics
from its predecessor the MCW50, such as the use of built-in quick-connect
fittings and the same outer dimensions, but it also features several
major enhancements:
- Performance is significantly
improved thanks to a complete redesign of the internal hydraulics
which result in lower processor temperatures (and better overclocks)
than the MCW50.
- The housing is now made out of Delrin as opposed
to Aluminum for prolonged durability.
- The seal between housing and copper base plate
is an O-ring for superior reliability.
- Improved and more reliable mounting system
for nVidia based platforms.
In its black and chrome trim, the MCW55
VGA cooler is a perfect match to complement either the MCW6000
or STORM CPU water-blocks.
Major features summary:
Extreme performance:
- Optimized hydraulics improve GPU heat dissipation
with minor impact on system flow rate
in liquid cooling systems powered by high-head capability pumps
such as the MCP350 and MCP655 pumps.
- 1/2" quick-connect fittings provide optimal
flow rate in 3/8" systems, and perform on par with traditional
1/2" barb fittings with the optional
tube-to-barb adapters
- Diamond-Pin Matrix© copper base plate
for optimal heat transfer, and turbulent flow
Versatility:
- The dual retention mechanism provides compatibility
with most high-end graphics processors such as ATI® Radeon™and
NVidia® GeForce™ families of products.

Performance and flow data
Click on picture to zoom in
This graph shows a higher
pressure drop for the MCW55 which will result in higher
performance as can be seen below.
|
Click on picture to zoom in - (Lower is better)
The MCW55 shows an average
of 0.02 improvement in C/W accross all flow rates. For
exemple, this would represent a 2°C lower processor
temperature at a 100 Watts load.
|
Click on picture to zoom in - (Lower is better)
This chart illustrates the
higher efficiency of the MCW55 vs the MCW50: at a given
pressure drop, the C/W is better by an average of 0.015.

This chart illustrates the
minor (0.1 GPM average flow rate reduction) impact of
adding one or even two MCW55 VGA coolers to Swiftech's
CPU liquid cooling systems.

Graphics card compatibility and retention mechanism
The MCW55™ ships with a dual retention mechanism composed
of spring loaded screws providing off-the-shelf compatibility
with all ATI® Radeon™ products as well as nVidia®
GeForce™ high-end (6800 and all GeForce 7 series) families
of products.
Optional hold-down plates are available for nVidia midrange GeForce
families such as FX, PCX, GeForce 6600 and below. The product
can also be installed with other graphics processors by using
permanent bonding agents, such as thermally conductive epoxies.
Swiftech guarantees compatibility with ATI and nVidia reference
models only.
Spring loaded assemblies feature compression limiters, to prevent
over-tightening of the waterblock to the graphics processor.
SLI Installation illustration:
Showing the Asus A8N SLI Deluxe motherboard: "there
is plenty of clearance for the water-blocks; installation of the
lower water-cooled VGA will obstruct one PCI slot (two PCI slots
do remain available, as shown above with sound and network cards
installed)."
Optional hold down plates for nVidia
midrange products
- Adapter kit for nVidia® FX and GeForce 6 mid-range (6200
to 6600) series - Not necessary for 6800 series and higher.

Optional Fittings
-
1/2"
Tube ID Hose barb adapters - part # PI251616S "Fitting:
1/2 in. Stem to 1/2 in. barb"
Notes: flow-wise, these fittings are equivalent to standard
brass 1/2" barbs. The red clip is provided to prevent
any accidental removal of the fitting during operations.
-
(1/4" ID tubing) for compatibility with other
manufacturer systems using small diameter tubing
MCW55™ Specifications
Housing:
- CNC machined Delrin® Acetal L2"xW2"xH1"
- Built-in quick-connect fittings for 1/2" OD tubing (3/8"
ID)
Base plate:
- 0.350" thick CNC machined copper base plate
- Submersed face is CNC machined from billet to form our award
winning Diamond-Pin Matrix. The design increases heat dissipation
surface, and flow turbulence to enhance heat transfer to cooling
fluid.
- Exceptional quality and attention to details: the base
is lapped to 0.0003" (3/10 of 1/1000"), and polished
to near-mirror finish to promote optimum thermal conductivity.
Users are advised that while flatness is strictly respected
for providing the most significant benefit to thermal interface,
surface polish is a cosmetic component and may vary slightly
from one heatsink to another. Re-lapping or polishing the copper
base is never recommended. Center section is raised to provide
clearance for stiffening frames.
