Fuzion Nozzle Kit Thermal Performance Link

[Martinm210]

This is not mine, but I thought it was interesting and a good example of another way to do thermal testing that includes a few more variables.

I've been having PM discussions with him for a while now about doing pressure drop testing similar to what I've been doing. In the end his restriction measurements appear to be higher than my own, but relative comparison between different blocks looks to be right on with what I got.

He used a very accurate thermocouple (.01C resolution) on the base of the processor and the other in the water, so it's a very accurate measurement of delta between the two taking out any error in the processor based location. I'm not sure exactly how this would correlate to core temperatures, but it is at least indicating that the one spot measured continued to improve even down to the 3.5mm nozzle.

To me this would indicate that for single core processors the smallest nozzle may be your best selection, and as you spread out that heat signature that that will probably change.

I particularly liked the way he plotted the temperature deltas over flow rate, it's very interesting.

The other very very interesting thing about this testing is that it shows that flow rate becomes more and more critical as the restriction goes up. Look at how steep the curves are for the 4.5mm and 3.5mm nozzle as well as the supreme. This would explain the cases where folks are seeing optimal temperatures with some really strong pumps even though heat dump from those pumps is pretty high.

Glad to see this level of testing, very very nicely done
