Excellent fans, but with a caveat
by BobLook excellent, cool brilliantly, nice and quiet, and with software that makes other manufacturers efforts look like a joke (talking about you corsair), but there is one issue you should be aware of, and that's why they are only 4 star. These fans are a couple of mm wider than a "standard" 140mm fan, meaning that if your cases 140mm spots are tight these just won't fit. I tried one in the rear spot in my Antec C8, replacing a standard 140mm fan, and it wouldn't fit. I also tried them in the front of Lian Li's own 011D Air Mini, and they won't fit in there either. You would have thought Lian Li would have checked compatibility with their own cases, but there you go. Anyway, if they will fit, they are easily the best looking, best performing fans I've ever used, and would recommend without hesitation.
