What is the difference between PWM and FLX?

Table of Contents

A: PWM is variable speed through software. FLX is fixed speed.

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 FLX case fan?

New. NF-A14 FLX. The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans.

Are Noctua fans PWM?

Connector: Noctua fans are available with standard 3-pin and 4-pin PWM connectors. The latter can be identified by the “PWM” designation. Choose 4-pin PWM versions if you would like to use the PWM fan speed control of your motherboard (or other devices).

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.

Are Noctua fans the quietest?

Is a PWM fan better?

Power Consumption Due to the way PWM fans function, they’re generally more efficient than DC fans and use less power. Consider the duty cycles of PWM fans. When a fan is on a 40% duty cycle, it’s only using electrical power 40% of the time. In comparison, the DC fans, if anything, will use a slightly lower voltage.
