Revision 3
The
component most vulnerable in any water cooling system is the pump. A pump with a short
life span would mean frequent system maintenance at best, or a damaged CPU at
worst. When Swiftech moved into the Revision 2 series of coolers, they abandoned
the MCP·600 inline pump in favor of the MCP·650. The 650 featured a higher
service life in addition to providing better performance. While this did come
at the cost of a slightly higher power consumption rates, a louder noise level,
and requiring more room to install -- the new pump was met with great success in the Overclocking Community.

Revision 3
of the Swiftech kits will feature a pump made by Laing Thermotech Incorporated.
The Laing Delphi DC pump is well suited to PC water cooling applications, being
small in size and being molded with 3/8 ID fittings for hose connections.
Swiftech calls the pump the MCP·350 and has attached a foam base with adhesive
to help mount the pump and reduce the noise from vibration at the same time.
Attachment screws are also available that will be mated to tapped locations on
the underside of the pump.

The pump is
marked with an arrow on the bottom fitting (picture oriented) to indicate the
direction of water flow. The pump is rated to a volume liquid temperature of
140°F at 22 PSI. At maximum rated voltage (13.8Votls) the pump will deliver 1.75
Gallons per minute, or 400 Liters per hour. These ratings are considerably lower
than the MPC·650, but the trade off has been made to keep the system as quiet as
possible and also relaxes the power consumption on your power supply. Many users complained about the noise of the pump and turbulence
created in the reservoir by the higher rated MCP·650. In a system that is only
going to utilize a single water block and radiator, I'm sure we'll find the new
pump will work out quite well.
