Interesting. Info I am definatly greatful for.

This is what my previous post was based on.

This now gives us a predicted correlation for the relationship between the final CPU temperature as affected by the flow rate, but more importantly also after factoring in the pump heat.

Eheim 1046, WB delta = 100W * 0.187C/W = 18.7C, Water delta = (100 + 1.5)W * 0.045C/W = 4.6C, Total CPU temperature = 23.3C above ambient
Eheim 1048, WB delta = 17.8C, Water delta = 103 * 0.044 = 4.5C, Total CPU Temp = 22.3C above ambient
Eheim 1250, WB delta = 17.2C, Water delta = 109 * 0.043 = 4.7C, Total CPU Temp = 21.9C above ambient
MCP600, WB delta = 16.9C, Water delta = 108 * 0.042 = 4.5C, Total CPU Temp = 21.4C above ambient
MCP650, WB delta = 16.8C, Water delta = 115 * 0.042 = 4.8C, Total CPU Temp = 21.6C above ambient
MD-15R, WB delta = 16.5C, Water delta = 122 * 0.041 = 5.0C, Total CPU Temp = 21.5C above ambient
MD-20RZ, WB delta = 15.9C, Water delta = 131 * 0.040 = 5.2C, Total CPU Temp = 21.1C above ambient
MD-30RZ, WB delta = 15.7C, Water delta = 150 * 0.039 = 5.9C, Total CPU Temp = 21.6C above ambient
