I wish this is a "choose 3 items" kind of poll. Anyways, I voted for the Noiseblocker fans.

* NoiseBlocker PWM pans: Noiseblock has been getting a lot of good reviews from other sites. The previous generation NoiseBlocker fans were SPCR recommended. I'd like to know how much of an improvement the new fans are.

* San Ace Pulled from the Seasonic X 650: would be interested in the results, even though these are impossible to buy.

* Silverstone 120mm & 180mm Air Penetrator AP121: obviously, this fan will have high turbulence noise. The question is how much better it performs (or maybe not at all).

Here is the specs on the family of NMB fans that Dorothy Bradbury sells:
http://www.nmbtc.com/cgi-bin/start.cgi/ ... _size=4.69
These are the two 120mm models she sells:
4710KL-04W-B10
4710KL-04W-B50
(her exact models may have slightly higher grade bearings and electronics)

If you click on the PDF on the above page on NMbtc's website, you can see detailed graphs of their performance. Notice the relationship between impedance and CFM.

NMB fans tend to have a fairly smooth slope. Most the fans take a big hit in CFM when they hit a certain back pressure point. In the NMB fans this wall is less pronounced than many others. A good flexible CPU fan should have a smooth slope on that graph.

I believe that most good case fans likely have a bigger and earlies drop of off performance against high impedance.

I would like to see Mike find a fan with well documented Specs like the 4710KL-04W-B50 and use it as a reference fan to compare against other CPU fans.

I really wonder, what does that graph look like for the Nexus, the Slipstream, the Sflex and the Noctua? I think knowing that might help us better select certain fans for certain situations.

Not exactly true, but at around $150 it would be the most expensive fan you ever bought :) Though I think I have seen the local Microcenter selling Noiseblockers for prices approaching $50.

That isn't that obvious to me. You may be right, but I think it would be worth testing to see if in fact that is so - and if so, to what extent.

Here is an example where that kind of information might be helpful:

I voted for the Noiseblockers, too. I've actually already got a couple of M12-P fans (mounted for intake) and they're pretty quiet. I think most of the noise I hear from them is actually wind noise introduced by the filter screen they draw air through.

But another fan I'd like to see reviewed that no one has mentioned is the Scythe Slip Stream PWM (SY1225SL12LM-P). I've got one of these and it seems very quiet. Its spec'd CFM rating of 74.25 is impressive; however, I'm so far not terribly impressed with its performance as a CPU fan. In fact, I'm going to try replacing it with a Noiseblocker XLP.

I'd also like to add my voice to those expressing interest in the forthcoming Silverstone AP121. In fact, I'll broaden this a bit: it would be great to see some special attention given to preferred applications for fans that promise a higher static pressure. Comparing these fans to some more conventional choices could be very interesting.

Missing in Action:
I should have included the Scythe Gentle Typhoons as well as the standard Scythe Slipstream PWM fan without the variable controls, in the list options to vote on.

Aside from FDB series, Thermalright has also released X-Silent 120 which is very quiet from my experience. I would like to see them being reviewed by SPCR.

I have thermalright X Silent 140.
Good fan, but IMHO, I prefer the Noiseblocker PK-1 because is a little more silent.
Also, I love the FDB S-Flex motor @ <700rpm

Joy!

Well I already answered for 140mm fans, but I would specifically like to see Coolink 120mm fans, Noiseblocker M12-S1 and S2, PK1 and XK1 and Scythe gentle typhoons. And I would like to have my mind blown away with some really good 140mm fan.

What about the new Noctua NF-S12B range? They are proven to be a lot better that the original NF-S12 fans reviewed on SPCR.

I recently replaced my very old P5W motherboard with a P5Q, which requires a 4-pin PWM CPU fan if you want to control the speed.

I had a Nexus 120mm PWM fan lying around (bought some time ago on a whim), so I stuck it in.

Very disappointing. At 12V, this fan is loud and obnoxious (over 1800RPM, with a hum/buzz in addition to the whoosh). Rebooting with this fan is an ordeal.

At 4% :shock: in SpeedFan (600 RPM), it is quite a bit louder than a classic orange Nexus at that RPM. It doesn't click, but it does kind of buzz. Still, at this speed, buried deep inside a P180, it can't be heard. So it's good enough, just disappointing.

I voted for the 140mm fans, but I'm really intrigued by the silverstone air penetrator fans, I haven't seen any reports on those at all, it'd be very interesting to see if they lived up to their claims.

I'd love to see a review of quality quiet 180mm fans! Does Nexus, Scythe or Noctua have a 180mm fan in the future? Surely Silverstone aren't the only source of 180mm fans are they? I'd like to see fans that can fit in the raven / fortress ft-02 cases.
