Noctua has announced a trio of new 140mm fans to be added to its recently announced A-series of premium quality quiet fans. The three fans carry model numbers NF-A14 FLX, NF-A14 ULN, and NF-A15 PWM and all feature Noctua AAO frames and Flow Acceleration Channels. The NF-A14 models feature mounting points for 140mm fans while the A15 features mounting points for 120mm fans. Noctua believes that the A14 models would be great for use in watercooling setups or as an upgrade to 140mm case fans, and the A15 would be a great addition to a CPU cooler. The A15 comes with full PWM control, and the FLX and ULN are capable of variable speed settings of 1200/1050/900 and 800/650 RPM, respectively. Noctua CEO Mag. Roland Mossig said "Introduced in 2009, our NF-P14 has become a default-choice among PC enthusiasts looking for a premium quality, quiet 140mm fan, so we're excited to further improve its much acclaimed airflow to noise ratio with the new NF-A14 and NF-A15."
