Now you are not mistaken, there are no audio results, and here is my take on why I didn't feel it was needed. As for the fans, radiator, case, power supply, and potentially other variables from my system to yours, the results I had with my radiator are likely going to be very different from everyone else's builds. If you want to know specifics, the fans on the radiator were delivering about 35dB of noise to the room, and the block was in audible from three feet away once the loop was bled out. This is why I say there is no real audio to report other than when you are trying to bleed the loop, then there is an obvious whine and spinning whir you have to hear until all of the air is out and the loop is flowing correctly.
I really like what Swiftech did with the Apogee Drive II. It takes away leak points, simplifies loops and cleans up the tubing runs, and adds a stylish component to your build with the flash of LED to dress things up. The performance of the unit was surprising; the Apogee Drive II didn't let me down in the least. I also did end up checking the temperature of the aluminum heatsink on the top, and I have to say it was working very well. With and IR thermometer, I got a reading of 41 degrees at the maximum end with ambient of 25 degrees. Since POM doesn't transfer heat that good, the heat I was seeing was being delivered by the pump. Even so, with this design, there is obviously very little heat dump from the pump into the coolant to achieve such efficient levels of cooling.
I did find a bit of garbage left over from the milling process of the POM in both of the inlet and outlet ports. What is funny is that it wasn't attached, but rather some sort of a snag-zone. I was able to remove the little bits of plastic, but since the block was obviously tested before I received it, I am not quite sure why they chose to stick in there rather than on the micro-pins of the copper base. Since the issue was easily rectified, I won't hold it against Swiftech; this is more of a request for a better eye on the quality control of the products before they leave for the customers.
With the good and the bad out of the way, I will tell you what I think about the Apogee Drive II. I don't really care what system you are building, this is a perfect solution to any water cooling build. I mean, what more do you want from a purchase than to be able to beat the competition? And I mean hands down beat them. As much as I didn't follow the recommendation of the right RPM fans in favor of silence, and using a 2 X 140mm radiator versus a 3 X 120mm I used in all the other tests, the Apogee Drive II integrated pump and CPU water block is just too good to pass up, and will be going into my next build for sure.
Swiftech did a great job with the development, incorporation of ideas and components, and pulled it off to deliver a product that should shock and awe those who thought they had the best CPU block money could buy - that was until they saw this.
