What does FLX mean Noctua?

What does FLX mean Noctua?

Hello. This term is mostly for Noctua fans: FLX means Flex or Flexible. It usually comes with a switch system to choose between 3 or more speeds, depending on your use, thus the “flexible” name. ULN means Ultra Low Noise.

What is the CFM of a Noctua fan?

Noctua NF-F12 PWM Overview Delivering 54.97 CFM of airflow at 300 to 1500 rpm and 22.4 dBA, this fan also comes with a low-noise adapter that can reduce fan speed to 1200 rpm while also reducing operational noise.

Which is the quietest Noctua fan?

Noctua NF-S12A—For Case Cooling The PWM has the most airflow at 107 CFM, and the ULN is the quietest.

What is 3 pin FLX?

3-pin FLX version provides 2000/1700/1350rpm speed settings via Low-Noise Adaptors to fine-tune the fan for maximum airflow or near-silent operation. Includes anti-vibration mounts, radiator gasket, fan screws, extension cable and 3:4-pin adaptor for powering the fan directly from the power supply.

Why are Noctua fans so quiet?

There are two big ones for this design. The first is that it allows the fan to be quieter. A lot of work goes into creating a near-silent fan. The entire unit vibrates, causing noise, which is why Noctua and some other companies package their fans with anti-vibration pads on the corners.

Which 140mm fan is right for me Noctua?

For 140mm fans, there is no such distinction: Both the NF-A14 and the NF-P14 redux models are true all-rounders that provide outstanding levels of airflow and static pressure. Either of them works excellent both for case cooling and for use on radiators and heatsinks.

Why is Noctua fan so good?

Noctua’s new A-series fan has a tiny tip clearance—the space between the fan blades and the housing—of about 0.5 mm. This will make the fan more efficient, particularly when used in air coolers and radiators. “When you have a fan blowing against a heatsink or a radiator, it builds up pressure,” Dellinger says.

How long do Noctua fans last?

Noctua fans are supposed to have less clicking noises than other PWM fans when set to very low RPMs, and are rated >150,000 hours. Plain old ball-bearing fans last ~60,000 hours but do get noisier/rattlier over time.
