the only one for NZXT Phantom and underwhelming!

First, I bought this fan, knowing full well that it was very fairly efficient, and despite its excessive price, because after much research and DIY attempts, I realized that although it ' was the only fan that I can install in place of my original fan at the top of my NZXT Phantom (2011) ...

25 to 90 CFM and 20 db, it makes me think 2 times before advising NZXT Phantom again!

Anyway, I understand that this fan was not the same as the original tower (including rifle bearing instead of sleeve bearing) and many reviews claim that it is more efficient, more beautiful and quieter than the original one.

Besides the sticker, I see absolutely no difference with the original fan, it also runs fast, the blades are identical (they have the same air of lower quality (eaten) but I quibble), it illuminates equally and above all, we need exactly the same noise, more a cooler master 200 MegaFlow (19 db).

No use to pay 25, I returned (dailleurs thank amazon for its professionalism foolproof).

In short, if you have a NZXT Phantom (new models (5xx, 6xx or 8xx) may be different) and your original fan no longer works, or want to add one on top, you have no choice, purchase (or model without led a little cheaper) if not, I suggest you go your way!
