It looks like the NF-A12x25 may be getting some competition:
Quote:
Phanteks showed off its yet to be named upcoming lineup of fan prototypes with an enhanced "multi-faceted" blade design. These blades, made of fiberglass, work to minimize the bulk of the noise caused by the whiplash. Inspired by vortex-dampening wingtips of modern airplanes, the blades are curved perpendicular toward the edges, and maintain a 0.7 mm gap from the bore of the frame. The fans feature a "6-phase motor," although the company didn't mention what kind of bearing they use. The edges of the frame (near the mounts) feature vibration dampening silicone cladding. The motors feature daisy-chaining cables, so you can chain up to three fans and mount them onto a radiator with minimal clutter. The fans come in 120 mm and 140 mm, each with two thickness-based variants - 25 mm thick, and 30 mm thick. Phanteks doesn't have a concrete launch timeline other than "later this year." -- Techpowerup

It will be interesting to see how Phanteks' Fibreglass holds up against Noctua's Sterrox, and how much of a boast 30mm gives.

My only question is how much will this wunderkind of a HSF cost? Two NF-A12X25s and a redesigned HS with two more heatpipes. I wouldn't be surprised if it comes out at close to double the price of the NH-U12S.
See the video on this page from HEXUS.net. Noctua are estimating the price as $100 US/€100 and availability as end of this year/early next year.

In case somone is interested on the NF-P12 Redux PWM fans, i got my hands on them, and they are fine very much like the old NF-P12, good value but they cant be stopped i ran fanXpert3 three times on each and niether stoped ever (pretty much like thermalright fans), i leave you the FanXpert graph,

Maybe in a month or two ill do a temp/niose comparison with the NF-A12x25, just not enough time when i reach home, back on road again.

A ComputerBase review (in german) PC fan for radiators in the test: Arctic vs. be quiet!, Nanoxia, Noiseblocker, and Noctua. One of the Noctua fans compared is the NF-A12x25.

I like a lot that they measure temp/db, which in my opinion is the final out come of adding fans, cooling at the cost of noise, and it seems noctua wins on the chart. One interesting remark from it,
Quote:
Apart from the Arctic F12, all the other fans were free of subjectively noticeable noise at low revolutions.

Another day, another NF-A12x25 review or in this case two reviews. The links are for the test results page. The first is from GreenTech_Reviews (Russian) and the second from Hardware Inside (German).

I have a Mugen5 on the way home, im going to test on an open bench the stock glidestream on it, the NF-A12x25 and NF-P12 REDUX PWM, a Noiseblocker Eloop 120mm PWM PS, a Darkside 1850PWM, its kinda like a gentle typhoon but pwm, not sure if i still have an GT AP15 still (im almost sure i gave my last one to a friend that needed for a PSU, but i might have an 1150rpm).

I just wished i had a more quiet environment to test below 30db ='(

I'm seriously looking at mating a Kotetsu Mark II (which uses the same stock glidestream as the Mugen 5) with a NF-A12x25, so I'm looking forward to your results.

I think there's a lot of that going around -- it shows how much of a hole the lack of SPCR testing has made.

Noctua has released a LGA3647 version of the updated U12S featuring this fan in push-pull ($99.90 from Amazon).

In other news, US sellers seem to have sold out of the PWM version of this fan at MSRP (a third party on Amazon is selling it, for the desperate, at $89.99).

nice for comparisons...but this is a big qualifier...
Quote:
The ambient noise for this set of testing is 31 dBA, sounding like a silent basement. To measure noise levels that were softer, the Sound Pressure Level (SPL) was measured 10 cm from each fan. SPL was adjusted to 1 meter by subtracting 20 dB. The sound pressure meter is a Tenma 72-942. This sound level meter has a microphone which is not accurate under 30 dBA which is the limit of all but the most expensive SPL meters. At low levels sound measurement by extrapolation is not accurate, so that sound measurements are approximate. But the bottom line is that fans making a Sound Pressure Level less than 11 dBA cannot be measured.

One more review: http://www.guru3d.com/articles-pages/no ... iew,1.html

Nice comparison of the range of Noctua fans.
