NF-A12x15 PWM chromax.black.swap, High-Performance Quiet Fan 120mm | High Airflow, Low Noise, 15mm Slim Fan, for Low-Profile CPU Coolers and SFF Cases, Customisable Color Pads, 1850rpm 4-Pin PWM

Standard Noctua experience. Incredible performance, quiet operation and keeps my pc cool. The thinner design made installation in my SFF a breeze. Always worth the price premium in my view.

These fans are amazing. I bought 2 for use in my small form factor case. They're being used as intake fans and I've set them at a constant 50% fan speed. According to my software 50% is 1100rpm and at that speed they shift a lot of air while producing no noise. I'm sitting about 1 metre away from the case and can't hear them. Above 50% and they are slightly audible but they move enough air at 50% so I prefer to just lock them at that speed. Having the colour options for the anti-vibration pads is nice. Allows you to match it to a particular colour theme you might have going on already.

I needed some thin fans for under my GPU - these are super! they are expensive but far better quality than the majority of other fans on the market. I really appreciate the rubber corner design, as these help eliminate and vibrations and noise from the fans. I am slowly changing all the fans in my case to this model as they perform so well and run very quiet.

I’m running a powerful gaming rig using mainly these and two other noctua fans, barley can hear and everything runs cool. If you want top performance buy noctua

Cant go wrong with any NOCTUA fans but for this sizing they aren't the "kings". Look at SILVERSTONE air slimmers for the best 120mm slim fans but I preferred the NOCTUA ones due to the quiet nature of them and the long warranty.

Bought this to stop my stacked hard drives from overheating due to the heat transfer from the bottom one to the one above etc of which I have 4. However the furing at the front of the case doesn't allow enough space for a 25mm fan so I got a 12mm one instead. Installation: I cheated on the installation by using velcro in the centre and corners because to screw it in place I would have had to remove all four hard drives, the drive case extension to get the fan in place .... forget that!!! and as it happens was a good choice anyway due to the poor design of the furing and screw holes. However, it would not have been difficult to fit on the average case. Performance: The fan just about creates enough airflow to keep the temperature of the HD at the top of the stack acceptable maxing at 46C whereas before it was getting to 80C. Also the fan is pretty quiet too so on the whole I'm happy.

As title - these look a feel really high quality and are almost silent even on full. Comes with splitter, extensions, everything to fit in most cases.

Brilliant fans, offer the performance while also keeping noise levels to a minimum.

Ventola fantastica, un po' costosa e' fatta di materiali solidi, il rumore e' limitato (ovviamente quando inizia a spingere si sente, come e' giusto che sia), funziona in PWM ed e' quindi settabile da bios collegandola alla scheda madre e profilandone il funzionamento (in base al sensore di temperatura scelto). La abbiamo acquistata per lo spessore contenuto di 15 mm, che ci ha permesso di montarla tra le lamelle del dissipatore per la CPU e il case, nella parte alta. Lo spazio disponibile era di poco sufficiente per l'installazione di questa ventola. Grazie alla ventola abbiamo risolto il problema del leggero overheating della CPU riducendo la temperatura del processore di 10 gradi ad alto carico e ottenendo una rapidissima (in una decina di secondi) stabilizzazione della temperatura da 60 a 35/40 gradi a basso regime. Nel nostro caso e' stata risolutiva.

Silent!!!!

Thin fans have problems moving air quietly. While not the most efficient at moving air, these Noctuas get the job done better than similar thin ones (and there aren’t that many to begin with).

Fan works, and it's not loud but when it arrived it was smelling awfully bad as chemicals or burnt plastic.

Quiet as a whisper, Noctua quality good for back of case when space matters.
