It's been pretty good so far. It's really loud out of the box, it defaults to 100% speed if no PWM signal detected. At 100% there is so much water pressure the reservoir looks like a shark attack and I can see the water spiraling up and down the tubes. I think part of the issue I was having getting the bubbles out is there was so much turbulence in the res that it was putting back the air into the loop again. When I lowered the pump speed to about 1900-2400rpm. The bubbles started to collect in my res. Also at that speed the pump is very quiet.
Sounds like you got some killer stuff on the way. Can't wait to see how you decide to run your lines. I don't like how mine are at the moment, I am going to tear it down and make some minor changes, also I have the 200 rad coming Friday and was going to have to change it regardless.
