I am considering MCP-35X vs. MCP655 but would consider any pump if I overlooked some good options. I like the idea of having a pump controlled by my motherboard but in the reviews I have looked at the 35x seems quit a bit louder? I am new to water cooling so could use suggestions. would be using a phobya xtreeme 1080 if I decide to go inside the case and a Watercool MO-RA3 9x140mm if I go outside the case. Large res if I make my own or a phobya 2 bay res if I am not so creative. Only cooling the one CPU at first but plan to cool 2 video cards later. Not sure how much of that matters but listed it for restriction purposes.
