Review: The best at a price - Do you hear that? No? That's coz its a noctua fan! Runs dead quiet and my previous issue of vibrations is remedied by the anti vibration 'screw' and pads. To be honest the offset speeds isn't something I can compare, but if the sync up sound has bothered you before, I'm sure they're good. In my opinion they are the absolute best fans you can get, but obviously you pay a premium. They're not the best value, be quiet and fractal are better. You're probably paying for a few decibels better, but if you want absolute best, you pay that premium.
Review: Well built simply the best but expensive - So my pc had been running hotter than normal due to weather and I thought it was time to upgrade some of the fans, noctua are the best always have been but not cheap, I went for 2 packs total 4 140mm. My current fans were Fractal which were ok as part of the PC chassis but not really cutting the mustard. The Noctua fans are 4pin PWM but work fine in 3 pin also, I installed two at front to pull air in replacing the 2 Fractal 140s, one at the rear as the exhaust and one above the processor as a secondary exhaust. Once booted up I ran the ROG fan tuning and that was it, they are louder then the Fractal but not in a bad way as they are shifting more air. My temps idle in this weather are about 46c, on load now is 71c which before I was 52/81 so well worth the investment. Such a well built fan comes with everything you need including extension cable. Buy them as my old analogy goes buy cheap buy twice yes they are expensive but honestly still the best. System for anybody interested is ryzen 9 3950 64gb ram and an old 3080, the 3080 need replacing at some point and that’s kicks out some heat but just waiting for prices to stabilise but most prob go back total red on a 9070xt as Nvidia prices ain’t cutting it anymore for the gains you get

## Features

- Dedicated dual fan set with two NF-A14x25 G2 PWM 140x25mm fans that are slightly off-set in speed (+/- ~25rpm) in order to avoid undesired acoustic interaction phenomena
- State-of-the-art engineering (Progressive-Bend impeller with winglets and Centrifugal Turbulator, Flow Acceleration Channels, AAO frame) and construction (Sterrox LCP, ultra-tight tip clearance)
- Ideal choice for push-pull applications as well as situations where two fans are operating side by side (280mm water cooling radiators, case intake or exhaust fans, etc.)
- Includes anti-vibration mounts, anti-vibration gaskets for tighter seal on radiators, fan screws, Low-Noise Adaptors (LNA), extension cables and y-cable for running two fans on the same header
- Trusted Noctua quality with premium-grade SSO2 bearing (MTTF > 150,000 h), safety certifications from UL and TÜV, protected against reverse polarity, over voltage and over current (short-circuits)

### ⭐⭐⭐⭐⭐ Whisper quiet and powerful
*by A***L on 29 January 2026*

I read up on these as I wanted a silent PC build. The Fractal case I bought was a little noisy for my taste so decided to replace the in case fans with these and what a difference it made! Temperature wise the CPU dropped around 5 degrees and noise wise they can barely be heard under my desk. They didn't replace the CPU fan directly, so this is purely configuring the ambient air flow so very happy with the results.
