> 24 hourLike all Noctua fans Ive used, this fan moves a lot of air and is almost silent. Using it for a push/pull on a Noctua NH-U14S. Very effective.

> 24 hourThere are less expensive fans out there and even more cheaper fans. I havent tried every fan on the market because Im not made of money but out of the fans Ive bought not only for computer cases, various CPU cooler and other projects these Noctua fans are great. I dont mind the colours but some people really dont like the usual Noctua colour scheme. I truly enjoy the near silence of these fans even when running at full speed. I bought one of their massive CPU cooling towers but with only one fan. Decided later to add the second fan just to see if it would help. I didnt really need it but with how quiet the first fan was I figured it wouldnt hurt to throw in a second one and see what happened. Even with the two fans I have to try to hear them. My cases fans are louder and are from a different manufacturer that are also supposed to be almost silent but arent as quiet as the Noctuas.

> 24 hourI have a Noctua NH-C12P SE14 CPU cooler in my latest build. It came with the 140mm round fan, but it had the 3pin power connector instead of the newer 4 pin PWM connector my motherboard wanted. The CPU heatsink is a huge thing and this 140x150x25mm frame fan is a better fit than the round version. The heatsink is a down facing model with the fan blowing down on the motherboard components. Big bonus is it seems a little quieter than the previous fan. Not sure if its the level of the noise or the color of the noise, but it sounds better. It comes with removeable rubber pads to keep vibration to a minimum in applicable installations. They didnt come into contact in my situation, so I removed them; but they would be sweet in other applications. SpeedFan 4.47, a Windows monitor utility, picks up the RPM signal from the fan. I dont bother adjusting the fan speed, its quiet enough to just run full speed all the time, which also gives max cooling to the motherboard components. Color ? Its a delightfully ugly color that grows on you. Yeah, its subversive and expensive, but capitalism at its finest.

> 24 hourExtremely quiet and smooth running fan. Runs fine off the case fan header connector on Gigabyte motherboards where another PWM fan failed to spin up without changing bios fan settings.

> 24 hourA sturdy fan in the distinctive Noctua colors, this fan has great build quality using premium materials. There is hardly any noise, even at high speed.
The NF-A15 is a premium quality quiet 140mm fan with a round frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. The NF-A15’s frame features 120mm mounting holes (105mm spacing) and has been enlarged to 150mm width in order to provide superior performance on today’s high-end CPU coolers. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 further improves the renowned quiet cooling performance of the award-winning NF-P14. Noctua’s custom designed PWM IC for fully automatic speed control and reference class SSO2 bearings ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and a Low-Noise Adaptor, the NF-A15 is a premium choice for the highest demands.
Round 140mm frame with 150mm width
The NF-A15 is tailor-made for use on today"s high-end CPU coolers: While its 150mm width matches those of most high-end heatsinks, its 140mm height doesn"t make it extend on top and thus ensures best case compatibility. The NF-A15"s standard 120mm mounting holes (105mm spacing) also make it an ideal performance upgrade for 120mm case or CPU fans.

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-A15 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. |
Flow Acceleration ChannelsThe NF-A15 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. |

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.
