A closer look.

The Noctua NF-S12A fans comes in the now “CLASSIC” Noctua color, some like it some don’t!
I don’t really mind it since the PC cases I’m using is meant to be quiet so I don’t se the inside of the case. The corners (on both sides) have been fitted with rubber ant vibration grommets a feature that is most welcome.

The big change to the NF-S12A has been made to the fan impellers, the new design has added “Anti-stall knobs”.

The NF-S12A’s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan’s stall margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.

 

Performance

Test system
Motherboard: Gigabyte GA A-A75-D3H
CPU: AMD A8 3870K (APU)
Ram: Corsair vengence 8GB
PSU: Antec HCG-620
HDD : Kingston SSDNOW V+100 128GB
Case: Antec Solo II (With two intake fans at 750RPM and one exhaust fan at 950RPM)

The test´s was done on the Noctua NH-L12 CPU cooler, Where each fan was run without any L.N.A/U.LN.A to get a view of the top performance of these fans.

Note that the included NF-B9 PWM has been removed during these tests!

I ran a Prime95 test for 30 minutes to get a good view of the CPU temperature’s, I shut of the PC for 20 min between each test.

Results

FAN RPM TEMP
NF-S12A PWM 926 52C
NF-S12A FLX 1200 46C
NF-S12A ULN 800 56c

 

Test Thoughts

It is easy to se that Noctua has once again provided a great cooling fan, and they manages to keep the AMD A8 3870K (APU) at very good temps.
Sadly I don’t have any way to measure noise but I am happy to say that the NF-S12A fans does not disappoint here either.
The NF-S12A FLX was barely notable from 1 meter distance, The NF-S12A PWM and the
NF-S12A ULN was completely inaudible.

Conclusion
When you think there is not much more that can be done to a fan Noctua proves you wrong!
I am happy to se the devotion Noctua shows in their continued struggle to provide their customers with high quality fans with great performance without sacrificing the acoustics.
The price for the fans are on the higher side at recommended retail prices of EUR 19.90 / USD 21.90 but you really get what you pay for!!!

Pros

  • Multiple Ant vibration solutions.
  • Great performance.
  • quiet.

 

Cons

  • A bit high price.

 

The Verdict
recommended

I would like to thank Noctua for letting me do this review.

 

And to my readers, THANK YOU!!
