Tailored for High-End CPU Coolers

The NF-A15 PWM is a 140mm case fan with a 150mm wide round frame that matches 120mm mounting holes at 105mm spacing. It is designed for builders upgrading 120mm fans or populating premium heatsinks such as the NH-D15 or NH-U14S where a 140mm height avoids overhang while the wider footprint covers the fin stack. The 4-pin PWM connector enables automatic speed control from 300 to 1200 RPM.

Bundled Accessories Extend Flexibility

A Low-Noise Adaptor caps the maximum speed at 900 RPM, dropping noise to 13.8 dB(A) and airflow to 52.21 CFM for silent operation. A 30cm extension cable eases routing in large chassis, while the 4-pin Y-cable allows two PWM fans to share one motherboard header. Four vibration-compensators and four fan screws complete the mounting kit for vibration-decoupled installation.

Airflow Headroom and Acoustic Limits

At full 1200 RPM the fan delivers 67.98 CFM at 19.2 dB(A), providing strong cooling for overclocked CPUs with a comfortable acoustic margin. The SSO2 bearing and >150,000 h MTTF rating support continuous high-load duty cycles. The 25mm thickness and 140mm height limit use in slim enclosures or radiators requiring thinner profiles, and the fixed brown colour scheme may not suit builds with strict aesthetic constraints.

Questions about this item

Does the SSO2 bearing need lubrication or replacement over time?

The SSO2 bearing is a self-stabilising oil-pressure design rated for over 150000 hours MTTF and requires no user maintenance.

What limits continuous airflow when the fan runs at full speed?

At 1200 RPM the fan delivers 67.98 CFM; the 19.2 dB(A) acoustic ceiling is the practical limit before noise becomes intrusive.

How loud and hot does the fan get after hours of 1200 RPM operation?

It peaks at 19.2 dB(A) with no LED heat contribution; adding the Low-Noise Adaptor drops speed to 900 RPM and noise to 13.8 dB(A) for all-day quiet running.
