Since there are less moving parts and a friction-less surface, the fans also have a longer lifespan. Noise is further reduced through the use of a magnetic levitation bearing which helps to minimize bearing friction. The ML120 is an 120 mm fan featuring an air flow rating of 47.3 CFM while only reaching a noise level of 25 dB.

However, they also create PC cases, meaning they know and understand the importance of adequate airflow. They're more so known for other components like RAM and peripherals like mouse and keyboards. Like Noctua, Corsair is an industry leader when it comes to computer components and hardware. This is thanks large in part to be quiet!'s fluid-dynamic bearings. Noctua is rated for 150,000 hours, where-as be quiet! is rated for 300,000 hours of use. However, where be quiet! does have Noctua beat is operation time. To note, both dB ratings are still whisper quiet in operation. This is a result of the funnel-shaped air inlets that allow for greater airflow capacity. However the be quiet is capable of pulling 13.3 CFM more volume while only being 6 dB louder. The Noctua pulls 60 CFM at 2,000 RPM and creates 22.6 dB of noise. Meaning the fan by be quiet is definitely impressive. However, you need to be educated when it comes to these metrics and how performance can actually be measured.įor example, here are the be quiet specs in detail:Ĭomparing these to the Noctua without the LNA: With the RPMs are reduced to 1700.Īs the name implies, be quiet!'s main focus is maintaining adequate airflow while still running at whisper quiet operation.Īs discussed in detail below, metrics like dB ratings and CFM values are important when looking at quiet PC fans. In terms of airflow, the Noctua is capable of 60 CFM at 2000 RPM. However with the Low-noise adaptor (comes packaged) it's rated at 18.8 dB which is very quiet. This helps with reducing resonance and vibration.Īs a result of this engineering as well as the above factors, the Noctua is rated at 22.6 dB. Noted for it's tensile strength, low thermal expansion co-efficient and damping characteristics. Their second generation SSO2 bearing features a rear magnet that's placed closer to the axis, which helps with stabilization and durability.Įven the fan blades are made of a Sterrox liquid-crystal polymer. In terms of noise output, Noctua attempts to keep things at a minimum. The flow acceleration channels assist in speeding up airflow at the crucial outer blade areas this lessens suction side flow separation, which in turn engenders better efficiency and less vortex noise. This Noctua model also features an award-winning A-series design with flow acceleration channels and an advanced acoustic optimization frame for a quieter cooling experience. The NF-A12 boasts four sets of mounting holes and also comes in a stylish but subtle beige on brown colorway. Might help illustrate why one would purchase their standard fans.Noctua has been a leader in the realm of fans and air-based CPU cooling for some 15 years, and if this NF-A12 model is any indication, they certainly haven't lost their touch. Perhaps a bit more expensive than your average fan, but Noctua's engineering makes it worthwhile. Overall Review: Very happy with the purchase. A 4-pin model is available, but be sure to check for it. This model is a 3-pin fan header, so no PWM speed control. Doesn't come with the vibration-absorbing bumpers (though they are available separately). Doesn't have the metal bearing housing the higher-end fans do (prevents dust ingress). Anyone who uses RGB lighting will find the gray picks up color better than the standard Noctua beige (or black).Ĭons: None of these mattered in my use case, but might matter to someone:
I think the label said it draws < 100 mA at max speed. Uses the same underlying bearing technology as all the other current fans. Even in the flat-out case, I'd have a hard time calling it noisy, or droning. No noise to speak of unless you're running flat-out. Pros: -Unbelievable airflow through a home-made intake dust filter.
