The MCW462-UH ™ water-block is designed for
extremely heavy thermal loads such as, but not limited to: overclocking,
multi-processors, thermoelectric cooling, and in general any application
requiring superior cooling performance.
Main features highlight:
Universal compatibility with all Intel® Pentium®4,
Xeon™, and all AMD® socket A motherboards featuring the
four installation holes surrounding the processor socket.
CNC machined and anodized aluminum block, with heavy duty C110
copper base plate, lapped to 8 Micro surface finish.
Focus jet cooling, with enhanced turbulent flow.
1/2" ID tubing hose barb fittings for extreme flow rate, and
minimum pressure drop.
Intel® Xeon™ processors, socket 603 and 604,
single or dual CPU configuration
AMD® Athlon® ,and Duron®, MP and XP
processors, socket 462
The octagonal shape of the MCW462-UH ™ has been designed as a
universal form factor for installation with all motherboards using the
above mentioned processors and sockets. The overall dimensions fit
inside the "no components" zone of both Intel® and AMD®
platforms.
The MCW462-UH ™ is shipped with all the accessories necessary
for installation with both Intel® and AMD®
processors.
Focus jet cooling: the inlet stream is located directly above, and
close to the heat source (processor, or thermoelectric module). This
effectively optimizes cooling where it is most needed: at the hottest
spot of the assembly.
The internal chamber
Heavy duty base plate:
The plate features a raised area .370" in overall thickness.
Altogether, the added mass effectively increases heat capacity
compared to earlier MCW462 models by 25%.
The area in contact with the heat source (processor or
thermoelectric module) is lapped, and polished to an 8 Micro Surface
finish to optimize heat transfer.
Eight 4-40 threaded holes are already in place to accommodate a
thermoelectric module assembly. See MCW462-UHT and MCW478-UHT
Thermoelectric assemblies below.
The copper base plate
The internal side of the plate features an irregular surface in
the area directly located under the inlet. This creates a turbulent
flow, and promotes heat exchange between the plate and the cooling
fluid.

surface. .
The base plate features a raised center section allowing clearance
for capacitors in dual Intel® Xeon™applications. Overall
thickness of the copper base-plate is .370" ± 0.005" ..

THERMOELECTRIC APPLICATIONS
The MCW462-UH is also available in thermo-electric configuration,
under the same specifications described in paragraph 5 above. Due to
different gasket systems between AMD® and Intel® configurations, the
product is identified by two separate model numbers:
Anti-corrosion protection : the MCW462-UH ™ body
receives a blue anodized anti-corrosion treatment. The process is
known to be the best available: Type II, class 2 (sulfuric acid
anodize).
Leak-free guarantee: The assembly is tested prior to
shipping under city-water pressure, and guaranteed leak-free up to 60
psi.
Safest mounting mechanism: Contrarily to socket clamping
mechanisms, the mounting system through the motherboard is proven to
protect the assembly against the worse shipping abuses.
Cold plate: to increase thermal capacitance, the cold plate is
1/2" thick. The plate is lapped on both sides to an 8 micro surface
finish. The unit is entirely assembled using Arctic Silver™ 3.

Power requirements: due to the very high current requirements,
this assembly must be used with a dedicated power supply. We offer the
following industrial power supply solution, or recommend similar
specifications for use with the MCW462-UT
The MCW462-UH and MCW478-UHT are intended for professionals, and/or
knowledgeable users, in applications where the processor needs to be
kept below ambient temperatures. Since these coolers are only part of an
entire cooling solution, including pump, radiator, fans, etc... the
temperature of the active cooling assembly will vary greatly depending
on: thermal load, components used in the system, and external operating
conditions. Swiftech cannot assess or anticipate performance results for
individual users projects, and invites prospective users to consult with
their Swiftech distributor or a qualified technician.

MCW-UBP rev 1: Copper base-plate is .200" at its lowest. The
heat spreader is raised to .170" for total base-plate thickness of
.370" ± 0.005". This provides clearance for capacitors in dual Xeon™
applications. Other specifications remain unchanged.
