Who it fits

Key specs explained for Noctua fans

Fan Size: 140mm

This dimension defines the physical footprint of the fan blades and frame. A 140mm fan generally moves more air at lower speeds than smaller 120mm units. This allows for quieter operation in your PC case. You should check your case specifications to ensure it supports 140mm mounts. Larger fans also help cool radiators more efficiently in liquid cooling setups.

Bearing Type: SSO2

SSO2 refers to Noctua’s Stabilized Static Oil bearing system. This design keeps the rotor stable and reduces friction over time. It contributes to a longer lifespan and consistent performance. The data indicates a mean time between failures exceeding 150,000 hours. This makes it a reliable choice for users who want fans that last without needing frequent replacement.

Connector Type: PWM

PWM stands for Pulse Width Modulation. This connector allows your motherboard to control fan speed precisely. It sends signals to adjust airflow based on system temperature. You get quieter operation at low loads and maximum cooling when needed. This is standard for modern PC cases. It ensures efficient power use and thermal management without manual intervention.

Model: NF-A14x25 G2 PWM Sx2-PP

This code identifies the specific product generation and configuration. The G2 indicates the second generation of this design. The Sx2-PP suffix denotes a dual fan pack optimized for push-pull setups. This helps you verify you are buying the correct pair for your radiator or case intake. It confirms the fans are matched for synchronized performance and acoustic balance.

Design and Build Analysis

According to the listing, this dual fan pack measures 5.51 by 5.51 by 0.98 inches and weighs 1.5 pounds. The fans themselves are 140 by 25mm units. This standard 140mm footprint allows them to fit most modern PC cases and radiators. The compact height ensures they clear many CPU coolers while still providing ample airflow surface area.

The construction uses Sterrox LCP for the frame and impeller. This material offers high stiffness and heat resistance. The design includes Progressive-Bend impeller technology with winglets and a Centrifugal Turbulator. These features help accelerate airflow and reduce turbulence. The AAO frame further stabilizes the unit. Together, these elements aim to deliver high performance with minimal vibration.

Noctua includes anti-vibration mounts and gaskets to secure the fans tightly. This setup is ideal for push-pull configurations or side-by-side mounting on 280mm radiators. The SSO2 bearing is rated for over 150,000 hours of operation. Safety certifications from UL and TÜV confirm electrical protection against reverse polarity and overvoltage. The packaging also provides extension cables and a y-cable for easy connection to a single motherboard header.

Setup and Everyday Use

Setting up this dual fan pack is straightforward thanks to the included accessories. You receive extension cables and a y-cable, which allows you to connect both fans to a single motherboard header. This simplifies wiring inside your case. The package also includes anti-vibration mounts and gaskets. These components help reduce noise transmission to your chassis or radiator. For tighter seals on radiators, the gaskets provide a secure fit. You can also use the Low-Noise Adaptors if you need to reduce speed further. The fans use standard PWM connectors. This means you can control their speed directly from your motherboard. The listing notes that the unit is protected against reverse polarity, over voltage, and over current. These safety features reduce the risk of damage during installation or operation. In daily use, the fans are designed for push-pull setups or side-by-side mounting. This makes them ideal for 280mm water cooling radiators or standard case intake and exhaust positions. The slight speed offset between the two units helps prevent acoustic interference. This engineering choice ensures smoother airflow without unwanted noise patterns. The SSO2 bearing is rated for a mean time to failure of over 150,000 hours. This suggests long-term reliability for continuous operation. The fans meet UL and TÜV safety certifications. You can trust the build quality for everyday PC use. The design focuses on quiet, efficient performance without complex setup steps.

Before You Buy This Pack

You should verify your case supports 140mm fans before purchasing. This pack fits standard 140mm mounts but may not suit compact cases designed for 120mm units. Check your radiator thickness if using these for AIO cooling, as the 25mm depth adds height. The included Y-cable helps manage connections, but ensure your motherboard has enough PWM headers or a compatible fan hub. Regular upkeep involves dusting the blades and frame to maintain airflow efficiency. These fans pair well with other Noctua products for a consistent aesthetic and performance profile. If you need high static pressure for dense radiators, this pack is a strong candidate. However, if you prioritize extreme quietness over raw airflow, consider single-unit alternatives. This dual set is ideal for push-pull configurations or large case intakes where two fans operate side by side. Always confirm clearance around the fan area to avoid obstruction from other components.

Check before you buy

• Verify your case supports 140mm fan mounts.
• Check radiator thickness for 25mm fan depth.
• Ensure sufficient PWM headers or fan hubs.
• Confirm clearance around the fan installation area.
