Product Description
Product Description
The MCP35X2 is the dual motor version of Swiftech's flagship MCP35X pump. The product is designed to provide extreme flow rates in loops that include multiple devices, for example multiple radiators and triple or quad SLI/Crossfire liquid cooled graphics cards;  pump redundancy also provides maximum safety in mission critical systems: if one pump fails, flow will continue to circulate thru the system thanks to the second pump.  The unit features:
  • The MCP35X2-H dual pump housing:
    • designed to provide considerably enhanced hydraulic performance;
    • compatible with multiple tubing options thanks to the G1/4 port standard;
    • compatible with the optional MCP35X-Res reservoir;
    • available in two colors; classic black or fashionable white
    • also sold separately, and compatible with all MCP35 series pumps
  • Two MCP35X pump motors:
    • 12VDC and PWM controlled, allowing variable speed control thru the motherboard from 1300 to 4500 rpm, and linked with Swiftech's PWM splitter cable for simultaneous pump speed adjustements using only one PWM motherboard header.

  • Small Footprint: L4.9" x W2.8" x H1.6" (L126 x W72 x H41mm);
  • 50,000 hours MTBF (Mean Time Between Failure) ;
  • 12 Volts DC convenience: plugs into the computer power supply
  • Variable speed control via PWM thru the motherboard, from 1300 rpm for completely silent operation, to 4500 rpm for ultra high flow performance;
  • Simultaneous pump speed control using one PWM motherboard header is achieved using the included PWM splitter cable.
  • Superior head pressure and flow rate (in the useable range) to any pump in its footprint: the X2 features twice the head pressure as the MCP35X.
  • G1/4" ports standard for compatibility with a large assorment of fittings;
  • No maintenance when used with distilled water, and anti-fungal additives (our HydrX additive is recommended);
  • Quick installation with adhesive neoprene pad, or permanent installation with supplied hardware;
  • Optional "built-in" MCP35X-Res reservoir;
  • Ready for upcoming 5 1/4" bay reservoir solutions by Swiftech.
  • 2 year warranty

The 35X was my favorite pump over the last year ... Swiftech has once again taken something great and made it better...I just found my new favorite pump or is that “Pumps”..:) " January 2012

Read Martin's Liquid Labs Review

"I really like the pump/reservoir combo [..] in a smart variable and warranty covered package." Feb 2011
"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

Best pump ever
Tom (UK) 10/8/2014 11:06 AM
Quite simply the best pump I have ever owned. I have 2 of them setup inside my Corsair 800D, 1 controlling the 3x GPU the other the CPU. You may ask yourself why you would need 4 pumps in a watercooled setup, well the answer is simple. Silence. I can run all 4 pumps at 30% producing no sound and achieve the same flow as 1 or even 2 pumps running at 100%. on full blast they achieve 110 gallons per hour, at 30% they achieve 40 gallons per hour. I have had this setup since they were first launched in 2011, and are still going strong as ever. Why this product only gets 3 starts amazes me. There is nothing out there that can beat this unbelievable product.
