txtmstrjoe's thoughts: This might be one of my absolute least favorite fans. Why do I dislike this one so much?
For one thing, it was a horrendously expensive fan. As I recall, I paid a touch over twenty bucks for one of these. I got two, and this particular one died within three days of me opening up the package. From the moment I sent power into it, it emitted an odd odor which I later discovered was the smell of fan motor grease. The little that this fan had burned away, and the fan seized. Thankfully, the vendor was satisfied with an online transmission of my invoice, and I was refunded for the cost of one of these horrid things.
(The second one hasn't died yet, but I absolutely refuse to use anything by SilenX now.)
I should have been alerted to the fan's suspect quality because it just feels so flimsy. It is easily one of the lightest 120mm fans I own; I have a 92mm fan that's a lot heavier than this thing. The plastic feels quite brittle as well. I have the impression that I could very easily break this fan with my bare hands, but the shards of cheap plastic would probably slice my hands to bloody shreds, so I've never bothered.
Another reason why I dislike this fan so much is because the manufacturer's claims for its performance are horrendously inflated. I don't have an anenometer to measure CFM output, but I'm very very sure that this fan produces far far less than the claimed 72CFM. How am I so sure? Well, I have some fans in my collection that allegedly produce less than 72CFMs, but they feel more powerful via the "hand test" (putting one's hand in the air pathway of the fan's outlet side). And I'm not the only one with a story of SilenX's fraudulent performance claims to tell. Many users have reported similar stories as mine, saying that while the fans are indeed quiet, they are also pretty gutless. An ant sneeze is more powerful than a SilenX Ixtrema.
I used two of these fans last year as case fans. Even with very low impedance, they seemed quite ineffective at moving air in any appreciable amount. Whilst a pair of these were mounted to my TJ09B-W, system temps were about four-to-six degrees C higher than any other fan mounted in the same positions.
There is no way I'll ever recommend using this fan for heatsink/radiator duty; they're simply just useless, in my opinion. About the only good thing I can say about these fans is that they have a beautiful shape; I like the small hub, as well as the aggressive appearance of the blades.
Unfortunately, in this fan's case, the beauty really was only skin deep, and it faded away rather quickly too.
