The MCW60™ waterblock is a next generation liquid cooling solution for high-end graphics processors (GPU's). It uses the same base plate technology as the award-winning Apogee CPU water-block for enhanced heat dissipation and optimum flow-rate in complete liquid cooling systems.
Companion products selection Guide
Depending on your graphics card model and application such as extreme overclocking, cooling of the surface mount components such as Ram modules and mosfets may be necessary, and companion products to the MCW60 are available in option as follows:
Use whenever needed for passive cooling of the Vcore mosfets

The MCW60 G80 adapter plate provides compatibility with nVidia's latest GeForce 8800 series vifdeo cards. Shown here with the MC8800 coolink kit on nVidia's GeForce 8800 GTX.
The G80 adapter kit is used to replace the standard MCW60 hold-down plate and allows installation with GeForce 8000 series Video Cards.
Features and benefits at a glance
VGA compatibility: the improved mounting system provides compatibility with most ATI® Radeon® and most high-end nVidia® GeForce® graphics adapters (see compatibility section for details).
Water-cooling system compatibility: The water-block ships with 1/2", 3/8" and 1/4" barbs for universal compatibility with any liquid cooling circuit.
Low water-block profile allows installation with nVidia's SLI and ATI's CrossFire™ systems.
The NPSM thread used in the MCW60 is BSPP and G 1/4 fittings compatible (see technical note on Fittings Compatibility)
The thermal performance model focuses extreme cooling where it is in fact the most needed: at the GPU level. This will afford better overclocks, and overall lower system temperature. Efficient and silent memory cooling is handled by using individual Ramsinks.
The MCW60 waterblock inherits all its thermal and hydraulic characteristics from the Apogee CPU water-block, in particular the Patent Pending Diamond Pin Matrix cold plate, proven for its thermal efficiency with today's high end CPUs.
Greater thermal efficiency is obtained thanks to the superior mechanical joint afforded by individual heatsinks compared to monolithic memory cooling solutions.
The housing is injection molded from POM (Acetal Co-polymer) resulting in complete reliability compared to machined Acrylic tops which tend to crack.
All hydraulic joints (housing to cold-plate and fittings) use o-rings for complete reliability and leak-free operations.
The mounting system includes a strong stiffening back-plate with a soft rubber center pad to prevent the circuit-board from bending .
In its black and chrome trim, the MCW60 VGA cooler is a perfect match to complement the Apogee CPU cooler, and the MCW30 Chipset cooler.
Lower cost of ownership
The injection molded water-block housing results in economies of scale, whereas the individual memory Ramsinks provide significant material savings compared to monolithic solutions. Cost of ownership is thus reduced by up to 50% compared to monolithic solutions, with superior performance where it really counts, and complete freedom in terms of graphics cards upgradability.
Performance and flow data

This graph shows a lower pressure drop for the MCW60 which will result in better flow rates and overall system performance.
Click on picture to enlarge
The MCW60 shows an improvement of 0.02 to 0.01 °C/W in the range of typical system flow rates (0.5 to 1.5 GPM). This is a 1 to 2°C improvement at 100 Watts.

This chart illustrates the minor (0.1 GPM average flow rate reduction) impact of adding one or even two MCW55 VGA coolers to Swiftech's CPU liquid cooling systems. With its lower pressure drop, the MCW60 will have even less impact.
Compatibility and retention mechanism
The MCW60™ is shipped with three separate retention mechanisms composed of spring loaded screws and back plates providing off-the-shelf compatibility with all ATI® Radeon™ and most nVidia® GeForce™ families of products as follows:
1. Pre-assembled retention mechanism using the four holes surrounding the processor:
Most high-end nVidia® GeForce™ series from 6800 and above (incl. latest 7900 series). See compatibility list below.
ATI® Radeon™ series from X1800 and above (incl. latest X1900 series) - Please note that Master cards for Crossfire™ Systems feature a compositing chip requiring an extra MC14 heatsink for cooling, not provided with the kit.

Good waterblock put in customer rig now bought one again for myself remember when installing this on the 8800gt to cool your mofsets i used the zalman heatsinks as they stuck a lot better then the swiftech ones and i have a antec spot cool fan cooling the card.
I bought this WB to save a bit of money over the full-cover blocks. It is not lapped and neither is the GPU core. Temps are great: 47 load and 41 idle on an 8800GTX running 660/1546/2050 clocks. I used DD 1/2" barbs and 3/4" OD tygon tubing with this block. I used Swiftech tube clamps on all other fittings but there was such little space between the tubing on the GPU block that they didnt fit. I resolved this problem by using 2 very small zip ties on each tube. These fit fine and did not leak at all. I will give this waterblock 4/5 stars because its not full cover. In every other aspect of design, this is a great waterblock. This review was modfied by poster i 05-17-08 09:22 PM

I have a pair of these, use one on my 8800GTX and keep the other for a spare, should I get a new videocard. I love these simple little blocks. Keeps my overclocked 8800GTX below 50 degrees at all times.
