How is this fan different to the first generation NF-A12x25?
The G2 version is the further improved successor and surpasses the original NF-A12x25’s performance, making it Noctua’s undisputed new flagship in the 120mm range.
How does the chromax.black version differ from the standard brown version?
Same performance, different colour: The chromax version is the all-black version of the fan, while performance and scope-of-delivery stay the same.
Can I use this fan on my watercooling radiator?
Yes, the NF-A12x25 G2 PWM chromax.black is a true all-rounder that yields superb results in all types of usage, whether it's case cooling, on heatsinks or on water cooling radiators.
How should I arrange the fans (PPA and PPB) when using more than two fans?
For an optimal placement, remember this simple rule: Arrange the fans so that PPA and PPB alternate by never placing two fans of the same type next to each other.
I need more than two fans, should I buy Sx2-PP sets or single fans?
If more than two fans that are running side by side, we recommend buying several Sx2-PP sets. If you need an uneven number of fans, combine the Sx2-PP set(s) with a single standard PWM fan that is sold separately.
- Dedicated dual fan set with two NF-A12x25 G2 PWM 120x25mm fans that are slightly off-set in speed (+/- ~50rpm) 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 (240/360mm water cooling radiators, case intake or exhaust fans, etc.)
- All-black chromax version with black anti-vibration mounts; 12cm anti-vibration gasket for tighter seal on radiators, fan screws, Low-Noise Adaptor (LNA), extension cable and splitter cable included
- Trusted Noctua quality with premium-grade SSO2 bearing (MTTF > 150,000 h), safety certifications from UL and TÜV, protected against reverse polarity, overvoltage and overcurrent (short-circuits)

Product Description

Sterrox liquid-crystal polymer compoundThe NF-A12x25 G2’s impeller uses Noctua’s Sterrox LCP, offering high strength, low thermal expansion, and excellent damping to reduce resonance and vibration in advanced fan-blade designs.
” data-position=”triggerHorizontal” />Extensive cabling optionsThe 20cm primary cable reduces clutter, while a 30cm extension adds reach. Both are fully sleeved, and a 4-pin splitter lets you connect a second fan to the same PWM header for automatic control.
