Introduction
The H20-80 revision 2 series liquid
cooling kits continue our tradition of plug-and-play and
balanced performance vs. noise cooling systems.
The kits' performance,
and convenience factors are now enhanced compared to the
original series models. This is due to the replacement
of the fill-and-bleed kit, by our new MCRES-525
5 1/4" drive bay reservoir, which yields a better
overall system flow rate.
These kits are specifically intended
to bring the efficiency, and quiet operations of liquid
cooling to confined environments. They require no case
modifications, and may be installed with all existing
components already in place inside the chassis (*)
The H20-80 series kits include
a number of options to accommodate most configurations,
from mild to extreme cooling, and they are ideally suited
for any chassis featuring 80mm fan intake and/or exhaust
openings.
Performance features:
- Extreme performance MCW6000
series water-blocks
- Extreme performance MCP650
12 Volts DC industrial pump
- 1/2" OD tubing for optimum flow
rate, and reasonable bulk
- Good balance for performance versus
noise is achieved with a single MCR80-F2
80mm copper-core radiator featuring an 80x25mm fan optimized
for low noise (28dBA) and high back pressure.
- Extreme performance can be achieved
by adding a second MCR80-F2 for a gain of up approximately
4°C.
Convenience & reliability features:
- 12 Volt DC pump plugs directly into
computer power supply
- High-reliability, no-maintenance
industrial pump features quiet operations thanks
to brushless motor, and is rated at 50,000 hour MTBF(Mean
Time Between Failures) equivalent to 5 year lifetime
- MCRES-525 5
1/4" Drive bay reservoir allows a quick and easy
procedure for filling-up the system
- 80mm form factor radiator fits into
any chassis featuring at least one 80mm opening for
fan intake or exhaust
- Pre-installed tubing on the water-block
and pump, and quick-connect fittings on the radiator
reduce installation time.
- Plug-and-play waterblock installation,
doesn't require removing the motherboard (most models)
- Coolsleeves
coils completely eliminate flattening of the tubes over
time, and enable users to bend soft vinyl tubing at
extremely sharp radii without kinking.
Optional devices and configurations:
- Add a VGA cooler such as the MCW50
- Add a chipset cooler such as the MCW20
- Add a second water block for multiprocessor
applications, such as dual AMD®, dual Xeon,
or dual Opteron.
- Add a second radiator for a performance
gain of up to 4°C at equal heat load. Note: this
option is always recommended in dual processor configurations

K7 platform.
Picture 1 includes an MCW6000-A
CPU cooler, MCW20-A chipset cooler, and MCW50
VGA cooler, and picture 2 is the same setup with
an extra MCR80-F2 radiator. Note the tight and "clean"
radii that can be achieved with the coolsleeves
coils.

Performance
data
To characterize the kits' performance
with different configurations, each kit was installed
in a bare chassis with a heat die simulator and then
tested in an environmental chamber where the radiator
fan inlet air temperature was held at 25.00°C ±0.02.
The thermal resistance of the system
could then be characterized by the difference between
the fan's inlet air temperature and the heat die, divided
by the heat load in Watts; such ratio is commonly referred
to as the "C/W".
The results below are accurate and comparable
as the only variables were the radiators, and fan voltages.
Users comparing their or other systems and data are
cautioned that such comparability is tightly dependent
upon how accurately the heat load (Watts) is characterized.

kit
** actual Watts measured at the heater of die simulator
*** Noting that "C/W"s are specific to an
individual test bench (due to the lack of standard test
methods); the system C/Ws described are those actually
determined with a specific water-cooling kit under the
conditions described above.
**** Fan noise estimate based on: "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 level by ~3dBA".
