Swiftech H20-APEX STORM "EXTREME DUTY" Kit Product Description & Info
Are you a die hard fan of the STORM water Block a follower of the man the legend the well-known
Australian engineer Stew Forster (AKA Cathar)
There have been some mixed reviews & in some independent test enthudiast claim that when liquid
cooling the CPU only the STORM seems to out due all other water blocks on the market today.
So if your an extreme CPU overclocker and are air cooling the rest of your components this kit may be
what you are looking for.
Introduction
The H20-APEX "Extreme duty" liquid cooling kit has been designed from the ground up to take full advantage of the new
STORM waterblock. It is the first kit in the industry to offer truly extreme dual use: maximum performance and minimum
noise in the same package.
Each and every component was optimized to produce what the die-hard enthusiast demands from a state-of-the-art liquid
cooling system. In the words of Bill Adams our VP engineering who dreamed-up this system, "you might be able to do it
cheaper, but you'd be hard pressed to do it any better".
Because of the substantial cooling headroom afforded by the combination of our new MCR-220 dual 120mm radiator, the
STORM waterblock, and the MCP655 pump, the H20-APEX 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.
Sacrificing to user convenience was not an acceptable option when we developed this kit either. Given its size, the MCR220
dual 120mm radiator will not fit in most PC's without extensive modifications. While many of our enthusiast users do not mind
using the dremel tool, we are happy to report to the less mechanically-inclined users that they have not be forgotten. The
H20-Apex kit is shipped standard with our MCB120 "Radbox" which allows the radiator to be installed at the back of
practically any mid-or full tower cases with no other modifications than a couple of holes. Overall thermal performance also
clearly benefits from the use of our Radbox, as explained here, and demonstrated in a number of field tests.
The massive MCR220 dual 120mm radiator fits nicely at the back of any mid-tower chassis thanks to the MCB120
"Radbox". Fan guards have been added to afford protection to the radiator's delicate fins. In this installation, which includes
a VGA cooler the inside of the computer remains relatively uncluttered.
Features and benefits
EXTREME PERFORMANCE
Features SILENT COMPUTING
Features
Capturing the heat Adjustable fan speed
The extreme performance STORM Universal waterblock is responsible for absorbing the heat generated by today's hottest
CPU's with incredible efficiency.
The kit is delivered with 12V to 7V and 12V to 5V fan adapters, enabling users to to reduce the fan speed -and noise, to
whisper quiet operations (~25 dBA).
Moving the Heat around Adjustable Pump speed
The Extreme performance MCP655™ 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.
The pump speed can be adjusted to virtually silent operation.
Dissipating the heat into the atmosphere Minimum toll on performance in "silent" mode
The new 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" optimizes cooling by using fresh air from outside the computer, without adding any thermal load to
other components.
The MCR-220 radiator fin density has been optimized to reduce air noise and operate at high efficiency with low-flow fans
At the lowest fan speed settings, the H20-APEX kit still delivers superb performance while allowing substantial overclocks.
For example, at 100 Watts, the CPU temperature is only 3°c higher than at the highest fan settings
SUMMARY OF BENEFITS
Maximum overclock Minimum Noise
*For reference, stock cooling solutions for current high-end CPU's are specified by manufacturers between 34 and 38 dBA.
Convenience and reliability features
Kit noise/performance ratio can be fine-tuned at the user leisure.
12 Volt DC MCP655 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.
MCRES-525™ reservoir fits into a 5 1/4" drive bay and allows a quick and easy procedure for filling-up the system
Universal STORM waterblock is compatible with all current desktop processors, and ships with all the different mounting
systems.
The Patent pending MCR-220 radiator is completely self-bleeding in upright position, or when installed on it's side.
Coolsleeves™ 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" provides a bolt-on mechanism to "hang" the radiator at the back of the case with minimum case
modifications.
Performance Data
Water-cooling Kit performance testing was conducted in an environmental chamber where the radiator fan inlet air
temperature was held at 25°C ±0.1. An industry standard heat die was used as a heat source.

FAQ: What can I expect the CPU temperature to be in my own system ?
In order to project what your CPU temperature will be, you need to know the following:
Power rating in Watts of your CPU.
Ambient Temperature inside the computer.
For example, if your CPU is rated by the manufacturer at 100 Watts, and the temperature measured inside your computer
(close to the fans inlet), is 25°C, then you multiply 100 Watts by our C/W rating of 0.125 (at 12 Volt) = 12.5°C, to which you
add the temperature inside the computer of 25°C, = a CPU temperature of 37.5°C at full load.
