Next you need to figure out where you want to splice in the "F" fittings and then connect the Ramcool to the "F" fitting with the supplied 1/4" tubing and clamps. Then, reconnect the GPU block to the "F" fittings and you're all set to fill, bleed and leak test the loop. The "F" fittings really make it super easy to run your tubing and make for a clean install. You will lose a little flow by adding another block in the loop, but throughout testing, I didn't get any loss of performance from my GPU block at all. My idle and load temps remained the same as they were before I installed the MCW-Ramcool.
About the only way to measure the performance of the MCW-Ramcool is to check the increase in performance of the video cards memory by overclocking it with and without the water block installed on the video memory. To overclock the card I used ATiTool version 0.25 Beta 14 and I also used it to check for artifacts as well. I also ran the card through five loops of 3D Mark 06 as well as Rthdribl v1.2 Demo (Real-time High Dynamic Range Image-Based Lighting) to check for visual artifacts and stability. And just to be sure the OC was stable, I was forced to play UT04 and Oblivion for hours on end; I really hated that part.

Results with the MCW-Ramcool Installed:
As you can see from the test results, the MCW-Ramcool performed it's task extremely well by helping to raise my maximum video memory OC, and I also got just a bit more out of the GPU as well even though my particular GPU doesn't OC very well at all. Both the GPU and ram will OC higher but ATiTool reports artifacts that aren't visible to the eye.
So far I'm totally pleased with Swiftech's new offering. It's build quality is top notch and it performs just as well as it looks. An added bonus of the block is that it helps to lower the overall temp of the video card. With standard ram sinks on the memory, the card radiated a lot of heat from the card. Now with the Ramcool installed, there isn't hardly any radiated heat to be felt coming from the back or front; it's a nice cool running card now.
If you own a later GeForce model video card and you're looking to get the most out of the video memory, look no further, this product has got to be on your very very short list of options. One small word of caution goes along with this. Make double sure that you have a reference designed PCB based video card as they are the only ones that the MCW-Ram will fit. If you're not sure, check Swiftech's web site for more info.
