So Cathar,
How does this pump fit into your ranking of water pumps? Or atleast, how does it fare vs. the pumps you tested in the thread over at ProCooling? I did some estimating myself to see if I couldn't maybe figure out on my own, and I came up with this pump looking to perform very similar to the Iwaki MD-15 @ 50hz. EDIT: Especially after I went back and reworked the data based on Cathar's measured head pressure.
Based on my superimposing the P-Q curve for the MCP655 over your graph of the other pumps and matching the values as closely as possible, I came up with the following (I also made a few assumptions on C/W numbers, but tried to approximate them based on similar performing pumps that you have values for already):
(EDIT: Changed numbers to reflect Stew's measured head pressure of 4.1mH2O)
MCP655 - flow rate: 6.8 lpm, Rad C/W: 0.041, WB C/W: 0.165
Performance - WB delta: (100w) 0.165 = 16.5C, Water dT: (100w + 21.6w) 0.041 = 4.98C, Total CPU Temp: 16.5C + 4.98C = 21.48C
This puts it right smack in the middle of the MCP600 and MCP650. Cathar, could you confirm/deny these numbers?
