MCP350™ Pump   

The MCP350™ pump has a lower flow rate, but a higher head pressure capability than the MCP650, which yields the same system flow rate.

When purchased with a water-cooling kit the barbs on the pump are pre-assembled with factory installed tubing already crimp fitted to the spigots for user convenience. If needed the fittings can be retrofitted with an alternative clamp by cutting the crimp fastener.

This pump can be mounted in any position. This includes up-side-down, right-side-up, side way's and in un-conventional configurations. It's very small size is a welcome to the water-cooling market as it can be stashed anywhere in the case and still put out the same flow spec's in any position! Only stipulation on this pump is the fact it cannot be submerged.

The MCP350™ pump uses a magnetically driven centrifugal 12 volt DC brushless motor. Despite its small size, it packs an amazing 13 feet of head pressure, which can be compared to the 10 feet featured by its big sister the MCP650. Connecting the MCP350 is a snap using a standard 12 volt rail 4-pin Molex connector. The pumps inlet and outlet are 3/8" O/D (outside diameter) and is compatible with 10mm I/D (inner diameter) tubing.

Design Advantages:

• 50,000 hours mean time before failure (MTBF)
• The pump is the smallest pump in its class and can fit into very confined operating spaces — virtually every desktop computer!
• Maintenance is not necessary under normal conditions and even after lengthy shutdown periods a reliable start-up is virtually guaranteed.
• The flow rate and performance characteristics can be easily controlled by voltage variation.
• The rotor/impeller is suspended in the pumped fluid and the rotor is self-aligning so noise does not increase over time.

The pumps electronically commutated wet rotor design, results in only one moving part in the entire pump.  A spherically suspended rotor/impeller rests on top of a ceramic ball and is driven magnetically, thereby eliminating the need for a shaft motor connection.  The pump lasts longer, consumes less power and offers superior performance characteristics when compared to other pumps in its class.

As shown above the kit offers pre-crimped tubing attached from the factory. When purchasing these parts individually, you will have to install the tubing yourself, using the worm-drive clamps supplied by Swiftech.

Quick facts:

The Pump is made by Laing (Hungaria). It was developed by Delphi for Apple, and is currently used in Apple's G5.

The MCW6000-775™ Water Block

The MCW6000-775™ water block is an extremely high end cooling solution for the Prescott Platform CPU's. Swiftech makes two versions of this water-block: one with a completely flat base that is compatible with Intel P4 (socket 478), Xeon (all versions), AMD Athlon 64, Sempron and Opteron (socket 754, 939,940), and a “stepped base” version which is the model used for this review, that is compatible with Intel P4 (socket LGA775), AMD Athlon MP, XP, Sempron, Duron (socket 462).

The inlet and outlet are no longer smooth as in previous versions, and feature a small barb to improve the seal between spigot and tubing. This now precludes the use of quick-connect fittings. In many cases, the same block can be reused with different classes of processors, by simply swapping retainer plates, thus reducing the cost of ownership. Here the block is factory assembled with 1/2" O/D tubing complete with coil sleeves. This is a standard feature when purchasing complete plug and play kits.

The "Stepped-Base" water block allows clearance over the LGA775 lever and is also a multi-class processor design as it allows the water block to fit on AMD socket 462 platforms as well. Having a "Stepped- Base" also means the standard water block orientation will be different when using this water block in conjunction with Socket "T".

This design has to be installed with the discharge spigot facing down. While this is not a problem at all in normal operations, it means that the water-block must be bled carefully prior to installation onto the processor.

The waterblock base features a thin pin design (281 pins). This geometry maximizes the surface area exposed to the fluid, and promotes turbulent flow; both factors, which also contribute to enhance the convection heat, transfer.
