One or more patents pending

MCR DRIVE-B versions (without pump) for existing MCP350 or 355 pump owners

MCP350 or MCP355 pump installation – skip this step if you have the MCR Drive with integrated pump version

Disassemble the MCP350 or MCP355 pump ports housing from

the main motor housing by loosening and removing all 4 screws.

Reassemble the pump body to the MCR drive radiator while making

absolutely sure to keep the existing pump o-ring in place or the assembly

will leak! To assemble, simply align the pump body with the MCR Drive

pump housing, and fasten it with the supplied 8-32 x ¾” socket screws.

MCR220 and 320 Drive installation

1. Installation of the fittings :

The MCR Drive heat exchangers are shipped with G1/4 x ½” barb fittings (12mm) . Use a 5/8” (16mm) flat wrench or preferably a socket

wrench to fasten the fittings very tight to the radiator body so as to prevent leaks.

The MCR Drive Rev3 series also feature two additional inlet ports that are available to parallelize various components in installations where

multiple waterblocks are present. See paragraph 5 below for more explanations on the subject matter.

. Installation orientation considerations and guidelines The primary consideration in the notes below is safety. Because this type of pump is not self-priming, it is essential to configure the liquid cooling system so that it remains self-purging, in other words, that any air travelling through the lines could never accumulate in the pump, thus causing coolant circulation to stall.

. Installation of the fans and to a panel: See schematic to the right. The 2 conventional methods to attach the fans and the assembly to a panel are: Standard: Using the provided four long screws (2) per fan thru the fan guard (3), the computer panel (1), and thru the fans (6) to fasten the entire assembly to the panel. Acceptable thread types: The original thread size is M3,5; standard US 6-32 thread can easily be used. Once 6-32 type screws have been used, going back to metric is not recommended.

. Electrical connections, pump general operations, specifications, warranty a/ Electrical installation: The pump uses two connectors: a standard Molex 4-pin (2 wires are used only) which connects to the PSU power connectors, and a standard 4pin (2 wires) which typically connects to the motherboard CPU_Fan 4 pin header.

b/ Operating precautions: The MCP35X pump should never be run dry, even for a quick test. You should always prime the pump by filling-up the MCR Drive radiator with fluid before you start operating it (see warranty note *). Use of coloring die or fluorescent additives containing particulate fillers will cause excessive wear to the pump’s impeller bearing (see warranty note **).

As mentioned earlier however, the consequence of parallelizing cooling devices is that the flow rate inside of said devices is also divided, therefore slower. So we now need to introduce another concept to further qualify the rationale behind parallelization: the heat flux generated by the different electronic devices, i.e. the rate of heat energy that they transfer through a given surface.

the “alternate” configuration could for example be beneficial as follows: • When cooling two CPUs, it might be desirable to parallelize them in order to maintain the exact same temperature for each CPU. • For one of the quickest upgrades ever: one could get started with a CPU-only loop, and use the alternate configuration initially.
