Product Description
Following the success of the original Maelstrom D5, Swiftech is proud to release its brand new flagship Pump and Reservoir combo: the Maelstrom D5 V2. Like its predecessor it comes preinstalled with the award winning MCP655-PWM (D5) pump.

The new Maelstrom D5 V2 reservoir features its unique smooth single profile square design and now also uses a durable crystal clear tempered glass tube at its core. It is still available in 4 different lengths: 50 mm, 100 mm, 200 mm and 300 mm. In addition to this wide range of sizes, the Maelstrom D5 V2 can now be customized with a choice of 6 Anodizing colors for the custom extruded aluminum trims. Although heavily inspired by the customization options we offer through our Heirloom Events, the Maelstrom D5 V2 is the first Swiftech product available all year with this many options (24 variations to be precise)!

The Maelstrom D5 V2 reservoir also comes with built-in addressable RGB lighting compatible with Swiftech's IRIS Technology (Swiftech's Iris Eco controller available separately) which is a great way to bring life in any custom build.

Installation of the reservoir into the chassis is handled by Swiftech's custom mounting brackets which are also included in Swiftech's MCP655/D5 pump tops. These innovative and modders-oriented bracket allows for both bottom and side panel mounting.

System fill up is done through one of the two top G1/4" ports (2x plugs are included). The other port can be used as a return line port to give modders the flexibility of routing the most complex cooling loops, just plug the other return port with the included plug.

Award winning MCP655 / Laing D5

Swiftech's choice of pump for Maelstrom D5 is the award winning MCP655 / D5 PWM pump which has been the "go to" choice for Gamers, Overclockers and Modders alike. The Laing/Xylem D5 pump is a high reliability, high pressure industrial pump, featuring a 50,000 hour MTBF. Such reliability is enabled by its motor design, which contains only one moving part: the magnetically driven spherical impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards.

The MCP655-PWM is completely plug-and-play, and connects directly to the computer power-supply with a standard 4 pin power Molex connector. It also features speed control through direct PWM connection to the motherboard.

Tab 1

  • 50,000 hours MTBF (Mean Time Between Failure) equivalent to 5 years lifetime
  • Molex 4-pin connectivity: plugs into the computer power supply
  • High pressure capability, ideal for both complex and high flow loops
  • The pump speed can be adjusted using the motherboard PWM signal (CPU Fan header) to yield top performance or virtually silent operations
  • 4x G1/4" ports (including 2x top ports for both filling and return line)
  • 2x G1/4" plug included
  • Bottom and Side panel mounting, hardware included
  • Built-in addressable RGB lighting, compatible with Swiftech's Iris Technology (Swiftech Iris Eco V2 controller sold separately), also compatible with most high-end motherboards with support for addressable RGB LED's (Swiftech Mobo adapter sold seperately).

"Operation of the MCP655 was vibration and, almost, noise free. With the side on the chassis, we couldn't hear the pump. And with the side off of the chasis and with Velcro the only thing holding the pump in place, we could barely hear it at all." October 2008

+  Great Performance
+  Extra Headroom For Overclocking
+  Delrin top removes aluminum from system (no mixed metals)
+  Fantastic retaining system (even if you do have to remove the mother board)
+  Excellent craftsmanship
