 motor noise
Reviewer: Im (1)
Used or using (all 120mm fans) enermax enlobal fan, noctua nf-p 12, thermal take tt-1225, vantec stealth, lian li case bundle fan and few other nameless fans (and of course this silent X ). None of the above fan had audible motor noise but this one. One of the enlobal bearing had epic fail after couple weeks and started to make grinding noise, but at least while it worked, it did not give off motor noise. Silent X, despite of its name, is anything but silent. Without any speed control the motor produces substantial noise, and with the speed control (matched to other fans rpm and/or aprox cfm) it still produces relatively high motor noise compare to other 120mm fans. It does pushes air quite a lot, but not surprising amount compare to Vantec high speed fan which with no motor noise. Blade noise and air friction noise is impressively low but it might have been the motor noise that masked it though. Construction feels significantly cheaper than noctua, but slightly better than enermax enlobal (which doesn’t mean a lot). If it wasn’t for the advertisement of theirs, I would say this is a good fan, but it does not live up to their claim and there are better choices like noctuas. If I were you, I would skip this one.
(Oh and skip enlobal series. Worst than free fan.)
 quiet, but not well balanced
Reviewer: theArthur (1)
it was almost inaudible at one foot, but so badly out of balance that it squeeked in its mounting. Perhaps mine is defective.

For it''s quietness, it moves a stunning amount of air. The fluid dynamic bearing gives peace and quiet, and piece of mind. I bench tested it against a similar Thermaltake, Coolermaster, Antec, Tek Chain, and Scythe. It''s quieter, or as quiet (nearly) and it sent papers flying!
Silent at 18dBA true, but 90 CFM no way!

Purchased 3 of these & installed
them on side panel (intake) on my CoolerMasterStacker 830 S2 Case. They are silent @ advertised 18dBA but despite no obstructions on intake or the output the air flow (CFM) is at best 2/3''s or 60 CFM? (Certainly not their advertised 90 CFM''s.)
Given the super high price SilenX should have at least included Fan LED''s for these.
They are much quieter then my other 5-120MM AeroCool Xtreme Turbine(w/ Blue LED''s) 89.39CFM @32.46 dB(A) case fans but do not even come close to matching AeroCool XtremeTurbine''s 89.39CFM''s nor their awesome appearance period! Over all, I''m dissappointed with these 120MM x 38MM SilenX 18dBA(True!)90CFM(NO WAY!) Case fans given their higher retail price verses their actual performance and very plain (non-LED)appearance.
quietEST fan I''ve tested yet

Provided you use the included rubber mounts, and provided you have the proper static air flow and have an unobstructed area for these to both intake and exhaust air, you shouldn''t notice these on until you crank up to the max setting.
Remember to check these fit for your application! I forgot to measure the screws for my radiator, and unfortunately was forced to modify this fan to attach to my radiator properly... humbug.
I have 4 of these in my case, and 2 120x120x25 MM silenx fans coming for my EXOS-2 this week. I was forced to order them from ggeweN because FrozenCPU was sold out of the 72CFM version for about a week.
I will be posting a rating of each of these fans using a DB meter borrowed from my father this week to prove/disprove the 18 dbA claim! Stay tuned.
 Unrealistic ratings.....
Reviewer: DaleRider (1)
Tested in a controlled environment....cfm rating is "ambitious" at best, actually delivers approx. 60% of rated cfm. Sound rating is about half of what it really has....which is low 30 dBa.
But, if you go to SilenX''s website, you''ll see how they arrive at their sound ratings, at least in part. Instead of one reading, they take one reading on-axis and two readings off-axis, all at one meter, and average the three readings. Of course, they never mention what voltage the fan is running at when taking their sound readings....my guess is around 5-7V. It certainly isn''t at 12V...any reputable testing site that has tested these fans can attest to how loud they truly are...Silent PC Review comes to mind.
Air flow is much lower than rated. Xtremesystems.org conducted an exhaustive fan test and these barely managed to put out 60% of their "rated" cfm....into air, never mind through a radiator.
In the end, overpriced fans with inflated ratings. And their small motors, that SilenX trumpets as helping quiet the fan, are simply too small and tend to overheat.
Save your money and buy a good fan, like a Scythe S-Flex or a Zalman F3.
 Does very well on a Thermalright Ultra 120 eXtreme
Reviewer: Andrey (4)
Before this fan, I had a Silverstone FM123 on my Ultra 120. A fin from this fan popped off and slapped me in the face. This fan is the replacement. I am impressed. The sweep of the fins allows for decreased flow pressure (not static pressure) despite increased thickness (38mm as opposed to 25mm), preventing flimsy fan blades from breaking off. Also, the specifications are not to be doubted. 90CFM it is, and at a virtually inaudible 18dB. You can feel the air flowing fast even through the restrictive Ultra 120. It is the third quietest fan in my case behind my SilenX 80mmx15mm fans (of which there are 3) and my 2 Aerocool Turbines (non-Xtreme). This fan is great...period. SilenX has proven itself to me as not a gimmick, but as a legitimate revolution in fan design.

Yes, the fan is thicker than a 120x25mm fan, but you should be able to see that from the specs - this one is 120x38mm. Perhaps I have other loud fans in my case (I know I don''t), but I can''t hear this thing at all. I hear my Zalman CPU fan spool up louder than this thing. And yes, it moves loads of air, and I mean loads. I have this as my primary exhaust fan without H20, and it dropped my idle temp by 3C and load temp by 1C. I suppose that''s worth the price :)
For those who doubt the specs.. Don''t.

The fan pictured is not this actual model. this one has bigger/deeper blades as its 38mm thick vs. the 25mm of the one pictured. In the photo of the multiple fans and sizes the 120mm pictured there is this model.
About the fan: it simply performs great. massive airflow and very very low noise. not silent but very close.
change of mind after two weeks....
03-21-2007
Reviewer: zgundam (2)
... after using this fan for roughly two weeks my opinion has changed - while yes the fan is dead quiet for a high cfm fan and yes it''s also dead quiet when undervolted, I don''t think this is really suited for use on a Radiator because static pressure generated by fan is not adequate enough compared to the Panaflo Medium''s - better stick with those if looking for ~85cfm high performance cooling
