> 3 dayAdding just one of these to my NZXT H230 dropped my Sapphire Radeon VAPOR-X R9 280X Temp by 5C while playing Sniper Elite 3. I got one empty spot and 2 stock fans I want to replace. Ill be getting 3 more of these.

> 3 dayLo compré para sustituir un ventilador pocho que me costó 4€ hará 5 años que había empezado a hacer mucho ruido. Hace el mismo ruido que el cualquier otro ventilador, no merece para nada el precio. No lo devuelvo porque me da una pereza tremenda desmontarlo, pero vamos, que si os hace falta un ventilador, con uno de 4€ de marca reconocida vas sobrado.

Greater than one weekThese works so well and are so quiet that I thought I didn’t plug them in. I had to look in my cases to make sure they were spinning from how quiet they are

> 3 day..dass die zusätzlichen Euros für einen Noctua wirklich was bringen sollen.

> 3 dayWeniger Luftdurchsatz als wie die Standart 120mm Lüfter meines Gehäuses und dazu auch noch gleich so laut. Wurden Gleich retourniert.

> 3 dayNoctua té diversos models i cal mirar bé lús que se li pretén donar a la seva web. Els hi ha per flux lliure (com aquest) i per flux més restringit més indicat per posar ben a prop davant la part a refrigerar (el radiador de la CPU o bé el radiador per refredar el líquid refrigerant de la CPU). Jo vaig posar aquest a la part superior de la caixa per treure aire (no hi ha res que entorpeixi el flux daire) i el NF-F12 PWM en una entrada a la caixa ja que just darrera hi ha un bon feix de cables i abans un filtre anti-pols,i volia una mica més de pressió per assegurar. Hi ha un altre model que encara dóna més pressió i que seria lindicat per posar davant un radiador o disipador de calor del líquid refrigerant. Ah, la denominació PWM indica que són ventiladors les RPM de les quals es poden controlar des de la placa base, altrament van a RPM fixes.

> 3 dayso quiet that i had to look see if it was working -- only problem is that i was a but clumsy installing one and pressed on one of the fan blades and broke it - spins but as off centre now need to order another to replace the one that I damaged

> 3 dayMan these fans really, really suck! Or blow, it depends on your orientation. After seeing how popular Noctua has become since my last computer build I decided to try them out on my rebuild for case cooling.
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.
