I have had these fans in my possession for a little while now and although I really wanted to just dive in, it was clear that to provide any results of use, a lot of thought would be needed in the testing and methodology to specifically provide results that were not only informative, but from which conclusions could clearly be drawn.Despite all the test results though, the conclusion is actually remarkably straightforward. Noctua makes great system fans.As above, the decision of which one/s you should get is ultimately directed by what your requirements are. The ULN models are a little more expensive than their standard models, but you get an excellently quiet performance and still remarkably good results. The better performing fans (in terms of speed) give excellent airflow but obviously run a little louder when put to the test.
