> 3 dayI needed a quiet fan for the low profile heat sink in my Home Theater Personal Computer (HTPC). I used a ASUS Z87M-Plus motherboard with ASUS Fan Xpert 2 Fan control software. Other PWM fans I tried would not spin down correctly and could not be calibrated to work with the automatic speed control of Fan Xpert 2. I installed this Noctua fan and it calibrated with Fan Xpert 2 perfectly the first time and now works to automatically control the fan speed based on the processor temperature. The fan runs full speed at 1200 RPM when the processor is at full load and slows to 250 RPM at idle. Even at full speed the processor the fan is quiet and at idle cannot be heard. Pros: comes with a full set of accessories, works great with Fan Xpert 2 where other fans wont and has a 6 year warranty. Cons: pricey compared to other fans. If I had purchased this fan to begin with I would have saved the days I spent troubleshooting my HTPC trying to find out the problem with the other fans not being sensed correctly by Fan Xpert 2. So much for being a cheapskate. Next time Ill buy this better fan to begin with.

> 3 dayThis fan is not that quiet. I got this fan because of the lower max rpms and supposed lower dbA since I have a 3 pin header, I figured a l.n.a. would be enough. Lo and behold it isnt, I even hooked up 2 l.n.as to slow the rpm even more but I can still hear it. According to speedfan 1 l.n.a dropped the rpm from 1200 to 1050 instead of reported 900, and 2 l.n.as dropped it to 950. Either the software is inaccurate or the resistors were off.

Greater than one weekOkay, Ill tell ya what ya already know (or at the very least have read).

Greater than one weekQuiet. It also solved my problem where the computer would randomly freeze a few minutes after first startup. Who though a fan could do that? Electrical noise? Old fan was noisy.

Greater than one weekVery quiet and good airflow. If youre only buying one or two fans, the abundant accessories will come in handy.

> 3 dayIch habe die Fractal Aspect Lüfter damit ausgetauscht und konnte eine deutliche Reduzierung der Lautstärke bei gleichbleibenden Luftdurchsatz und Druck erreichen. Der PC ist nun im normalen Gebrauch nicht mehr zu hören. Qualität und Leistung sind hier wirklich top. Der Preis dafür jedoch grenzwertig hoch.

The NF-S12A marks the third generation of Noctua’s signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
SSO2 bearingThe NF-S12A features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Inner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. |
Scope of delivery
|
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.
