Should I use L.N.A or U.L.N.A. cables with my Noctua cpu fan?

I just got my Noctua NH-U9B SE2. I am confused by the two wires (blue and black). I mean I understand the difference and I want to keep my pc quiet, but wouldnt the L.N.A.'s be better with higher RPM's? Which one should I use and why?

The best option for a CPU cooler is to automatically control the fans to speed up when CPU temp increases and slow down when CPU temps fall. That's controlled by the motherboard usually. If you have automatic speed control, you don't want either of the adpators.

What motherboard do you have?

I have the NH-U9B SE2. IMO, the U.L.N adaptor would be too slow for a CPU cooler. The L.N.A should be OK most of the time. That will spin the fans at about 1300 to 1400 rpm. Still pretty quiet.

Best cooling will come from not using either adaptor. I would try it that way and see if the noise is too much.

I mean, I would rather use the L.N.A. to be confident with cooling. Have you tried that setup? Is it really any louder than the Ultra's? Finally, Am I supposed to connect the LNA from the fan to the Y-splitter? im so confused.
