Product Description
Product Description
The patent pending MCR-X20 Drive™ series are high performance heat exchangers featuring two truly revolutionary features:  a powerful integrated pump with PWM control, and an integrated reservoir. This unique concept is the foundation for a simple, powerful, yet versatile liquid cooling system where only CPU and/or Graphics waterblocks need to be added.
Revision 3 brings another level of functionality and performance to this list of ground-breaking features by implementing Swiftech's innovative multi-port connectivity which consisted in adding two more  ports (for a total of three) to the inlet plenum.  When implemented in conjunction with Swiftech's new Apogee HD™ waterblock, this feature allows dramatic flow rate improvements in complex multi-block environments.
The heat exchangers are available in two versions: the MCR220 Drive™ for dual 120mm fans, and the MCR320 Drive™ for triple 120mm fans, as well as in two configurations each: either with or without the pump. When sold without the pump, any of Swiftech's MCP3X pump series can be installed (MCP350, 355, 35B, 35X)
The MCRx20 Drive™ series are also the primary building block for the H20-X20 Edge series of liquid cooling kits.

Tab 1

High performance Features


Three inlet ports provide return lines for up to 3 different waterblocks (use this feature in conjunction with the Apogee HD waterblock) Dramatic flow rate improvements in complex multi-block environments

The dual or triple 120mm radiator form factors provide 2 to 3 times the heat dissipation capacity afforded by the single 120mm radiators found in entry level kits.

Superior performance headroom

Substantially reduced operating temperatures

Ability to daisy-chain multiple water-blocks in the loop with reduced impact on CPU cooling performance

Higher overclocks

The high-pressure MCP35X pump now runs at up to 4500 rpm, and allows vastly superior system flow rates than comparably sized pumps found in entry level kits, allowing users to daisy-chain multiple water-blocks in the loop.

Integration of the pump into the radiator reduces the overall system pressure drop compared to conventional setups.

Convenience and Versatility Features


Three inlet ports provide return lines for up to 3 different waterblocks (use this feature in conjunction with the Apogee HD waterblock) No need for clumsy and cumbersome Y splitters

The patent pending integrated pump and built-in reservoir of the MCR Drive heat exchanger combine 3 of the 4 typical elements found in conventional CPU liquid cooling systems.

Easier to integrate in any PC

Simplified installation

Safer, more reliable operations (less joints)

The product is fully functional in both vertical and horizontal orientations Easier to integrate in any PC
PWM controlled pump enables variable speed from 1300 to 4500 rpm From virtually silent operations at low speed to ultra-high flow rates in multiple waterblocks (CPU + VGA's) and/or radiator configurations

Only the water-block(s) will need to be changed in case of platform upgrade.

Future-proof concept reduces the cost of ownership over the long term, and guarantees that the core cooling system can be migrated from one computer to another.


Tab 2

Performance curves of the radiators are similar to their respective non-integrated counterparts, the MCRX20 QP series and can be accessed in the links provided below.
It should be noted that overall system pressure drop is noticeably improved compared to a traditional setup comprising a separate pump and reservoir due to a substantial reduction in the length of the flow path, as well as in the number of fittings (2 fittings instead of 6).
For real-life performance data, you may also refer to a couple of white papers we recently published entitled "Actual Influence of Flow Rate on system Temperatures" and "Dual Loop versus Single, the Facts". These articles contain comprehensive information with respect to the thermal performance that can be expected from the MCR-Drive serie heat exchangers when coupled with other Swiftech® components in the loop.
Here is a summarized table of results; these tests were performed with Ci7 920 overclocked to 4.1Ghz and running at 1.39v; please also refer to the articles linked above for full configuration details, results and explanations.

T CPU Air °C: the difference in Degrees Celsius, between the temperature of the CPU and that of the ambient air. This presentation of the data identifies the CPU temperature independantly of ambient air temperature which varies greatly depending on local conditions, thus reflecting the true performance of the cooling system.

"To sum it up in a simple phrase, the MCP35X is a big deal. [..] PWM control of your pump is the game changer here. [..] The ability to change speeds when load/temperature increases without having to manually adjust the settings is a godsend, and now we can do this with our pump too that is huge! [...] The MCP35X is the best overall performing Laing pump I have tested to date..." Jan 2011

Pure OC Editors Choice

"... the H2O-320 Edge is indeed a unique liquid cooling kit. [..]  It is a new evolution of the water cooling kit and the worlds first traditional setup that combines a reservoir, pump and radiator in a whole unit to eliminate the tubing cluster without compromising the performance.  Not only does the performance stay impressively strong, the whole setup is extremely user-friendly as well. " Dec 2011 Logo

"Overall this is an impressive kit. The performance should be right up there with a custom loop [..] The H20-220 Edge has the flexibility to upgrade to future blocks for upcoming sockets, great performance [..], quiet operation [..], the ability to crank it up for some benching sessions when every °Celsius counts, and expandability to put more into the loop [..] when you are ready."

"Overall I was very impressed with the temps [..] And it looks pretty awesome!..if you are at all into serious overclocking or system building and you do not have custom water, its about time to take the plunge.pardon the pun. The Swiftech® H20-320 Edge Water Cooling Kit is gorgeous and anyone would be happy sporting one of these on their performance rigs." Oct 2010



First review of the new H20-320 Edge liquid cooling kit

"Although many dyed-in-the-wool water cooling users will turn their nose up at a liquid cooling kit, [..] I'd have to say the Swiftech® kits are by far the best..If you're looking to build a liquid cooled rig and don't want to mess around with buying parts piecemeal, the Edge kits are absolutely a great way to go."
