Does EVGA recommend a particular brand/model of pump kit to use with this card? Or better yet, are there some folks with this card who would share what brand AND model of pump kit they use, and the success they've had with it? Thanks in advance.

I have an EK reservoir and pump combo. They use a D5 which has been working great for 3 years. I dont hear it even at full speed but it's never at max rpm anyway. I was thinking on trying a corsair res/pump combo if this one ever went out.

Well, my D5 must have been defective but still operated properly for years. It was definitely louder than my current MCP35x. But as a matter of perspective, I had to run the non-PWM D5 at high speed to get good performance under load which created unnecessary noise at all other times; and there was no way that I was going to open up my case and adjust the pump speed with a screwdriver multiple times per day. On the other hand, my MCP35x idles at low speed, ramps based on a temperature curve, and rarely has to ramp up to high speed. So, it's just better in every way in my perspective.
And again, look at that flow versus pressure curve! It's excellent. More area under the curve = better.
