3. 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:

Either: using the provided four M3.5 short screws (1) per fan to fasten the
lower lip of the fans to the radiator body, and then another fastener of your
choice (not provided) to secure the assembly to the computer panel (3).
Standard fan screws often provided with the fans work well to attach the
assembly to the panel.

Acceptable replacement short screws types are: either US 6-32, or M3,5.
Screw length specifications are: Min: 1/4” (6mm) - Max: 5/16“ (8mm)

Or: using the provided four long screws (2) per fan thru the computer panel
(3) and thru the fans to fasten the entire assembly to the panel.

Acceptable replacement long screws types are: either US 6-32, or the
supplied M3,5.
Screw length specifications are:
- inch

Min/Max: 1 1/8” (30mm) this is the only adequate size available in this

size range for 120x25mm fans. Use 6-

32x1 5/8” or M3,5 x 40mm for

120x38mm fans.

WARNING: do not exceed the maximum recommended screw length or
irreversible damage to the radiator will occur, not covered under your
warranty.

You are now ready to connect tubing to the MCR Drive inlet and outlet fittings,
using the provided hose clamps, and to complete the loop by a waterblock of
your choice.

4. 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 connectors, and a standard 3-pin
(single wire) which connects to a 3 pin motherboard header, and allows the motherboard to read the pump rotational speed (RPM). This is merely
a sensor, and it does not allow speed adjustments.

b/ Operating precautions:

The MCP350 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 **).
