Introduction
The H20-120 revision 2 series
CPU liquid cooling kits continue our tradition of plug-and-play
high performance systems, by bringing to power users the
efficiency and quiet operations of a carefully matched
120mm radiator and fan.
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.
Whereas the H20-120 cooling kits
will readily install in most chassis featuring at least
one 120mm fan opening, they can also be installed without
case modifications in almost any desktop computer
by using our optional patent pending MCB120
"Radbox".
Reliability of
the kits is guaranteed by the new MCP650
pump featuring a 5 year lifetime.
The H20-120 series CPU cooling
kits include a number of
options to accommodate most configurations, from serious
to extreme cooling.
Performance features:
- High thermal dissipation is achieved
with a single MCR120-FB 120 mm copper-core
radiator featuring a 120x25mm fan optimized for low
noise (34dBA) and high back pressure.
- Superior performance at reasonable
noise can also be achieved by adding a second MCR120-FB
for a gain of up to 3°C.
- 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
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
- 120mm slim form factor radiator fits
into most chassis equipped with at least one 120mm opening
for fan intake or exhaust, and can optionally be installed
externally to the back of any chassis featuring at least
one 60, 80 or 92mm exhaust fan, by using our patent
pending MCB120 "Radbox"
- 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 MCR120-FB
radiator for a performance gain of 3°C average at
equal heat load.

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".
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".
