Introduction
The H20-220 Ultima XT CPU liquid cooling kit continues our long
established tradition of bundling our top performing components to
produce the best cooling kit the market has to offer. A declination of
this kit for complete system cooling is also available under the part
numberUltima
XT Plus.
Featuring what many consider as the world's best water-block: the
recently released Apogee
XT, the MCRES-Micro
Revision 2 , the classic MCP655-Bpump
and MCR220 dual
120mm radiator, the Ultima XT receives yet another quantum boost in both
performance and versatility.
As a result of the substantial cooling headroom afforded by this
combination of top performance components the Ultima XT kit will satisfy
both extremes of the enthusiast market spectrum:
- Overclockers in search of the lowest CPU temperatures
AND
- Silent computing users in search of the lowest possible
operating noise.
Whereas an increasing number of cases can now accommodate dual 120mm
radiators internally, users convenience was not forgotten, and the
Ultima XT is shipped standard with our MCB120
"Radbox" Revision 2 which
allows the radiator to be bolted-on at the back of practically any
mid-or full tower cases. Overall thermal performance also clearly
benefits from the use of our Radbox, as explained HERE,
and demonstrated in a number of FIELD
TESTS .

The MCR220 dual
120mm radiator fits nicely at the back of any mid-tower chassis thanks
to the MCB120
"Radbox" Revision2 .

SILENT COMPUTING
Features

|
Capturing the heat
|
- The world's most advanced Apogee
XTwater-block is responsible for absorbing the heat
generated by today's hottest CPU's with incredible
efficiency.
|
- Adjustable fan speed: the kit is delivered with 12V to
7V and 12V to 5V fan adapters, enabling users to reduce the
fan speed -and noise, to whisper quiet operations (~25 dBA).
|
|
Moving the Heat around
|
- The Extreme performance MCP655-B 12
Volts DC industrial pump pushes the coolant throughout the
circuit at high velocity.
- Larger 7/16" ID (5/8" OD) tubing is used to maximize the
coolant flow rate inside the system.
|
|
Dissipating the heat into the atmosphere
|
Minimum toll on performance in "silent" mode
|
- The MCR-220 copper
and brass radiator doubles the surface area available for
heat convection into the air compared to a single 120mm
radiator, and uses two 72 CFM 120mm fans, at a reasonable*
sound noise level of 37 dBA.
- The MCB120
"Radbox" Revision 2 optimizes
cooling by using fresh air from outside the computer,
without adding any thermal load to other components.
|
- The MCR-220 radiator
fin density is optimized to reduce air noise and operate at
high efficiency with low-flow fans
- At the lowest fan speed settings, the Ultima kit still
delivers superb performance while allowing substantial
overclocking. For example, at 100 Watts, the CPU temperature
is only 3°c higher than at the highest fan settings
|
|
Convenience and reliability features
|
- Kit noise/performance ratio can be fine-tuned at the
user leisure.
- The 12 Volt DC MCP655-B pump
plugs directly into computer power supply.
- High-reliability, no-maintenance industrial pump is
rated at 50,000 hour MTBF(Mean Time Between Failure)
equivalent to 5 year lifetime.
- The MCRES-Micro
Revision 2 reservoir
fits in any small space available in the system without
sacrificing a CD-drive bay and can provides up to 18 month
of continuous operations without refills. An additional
fill-port adds in installation versatility by offering users
multiple tube routing options and elaborate mounting
brackets allow installation just about anywhere in the PC.
Optional remote
fill-ports are
also available to further enhance the versatility of the
installation.
- The Apogee
XT water-block
is compatible with all current Intel desktop processors.
- The MCR-220 radiator
is completely self-bleeding in upright position, or when
installed on it's side.
-
SmartCoils 625 are
included with the kit, to completely eliminate tube kinking
for a safe and reliable installation.
- The 7/16" ID tubing features the same or better
flexibility than 3/8" ID tubing, no distinguishable
difference in terms of system flow rate compared to 1/2" ID
tubing, but significantly reduces the bulk associated with
1/2" ID thick wall tubing.
- The MCB-120
"Radbox" Revision
2 provides a bolt-on mechanism to "hang" the radiator at the
back of the case with minimum case modifications.

*For reference, stock cooling solutions for current high-end CPU's are
specified by manufacturers between 34 and 38 dBA. |

"If the speed of a fan is reduced by 20%, the decibel level will reduce
by 5 dB.", and "addition of a second equal source increases the sound
