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.

High performance Features Benefits
Three inlet ports provide return lines for up to 3 different waterblocks (use this feature in conjunction with the Apogee HD waterblock)

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.

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.

Dramatic flow rate improvements in complex multi-block environments

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

Convenience and Versatility Features Benefits
Three inlet ports provide return lines for up to 3 different waterblocks (use this feature in conjunction with the Apogee HD waterblock)

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.

The product is fully functional in both vertical and horizontal orientations

PWM controlled pump enables variable speed from 1300 to 4500 rpm

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

No need for clumsy and cumbersome Y splitters

Easier to integrate in any PC
Simplified installation
Safer, more reliable operations (less joints)

Easier to integrate in any PC

From virtually silent operations at low speed to ultra-high flow rates in multiple waterblocks (CPU + VGA's) and/or radiator configurations

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.

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.
