Design

The NB-BlackSilentPro is an Ultra-Silent, Premium-Class fan from the BlackNoise. It has been their popular and high-selling fan series. The fan comes in multiple sizes. Within each category, there are more versions with varying specifications.

Here is the listing of their entire BlackSilentPro PL PS Fans Review series of the fans:

Size (mm) Model Names
40x40x20 PM-1, PM-2
60x60x25 PR-1, PR-2
80x80x15 PC-P
80x80x25 P-1, P-2

120x120x25 PL-1, PL-2, PL-PS
140x140x25 PK-1, PK-2, PK-3, PK-PS

These fans are part of the IT series for PC users, not the Industrial Cooling Solutions. We’re reviewing the 120mm PL-PS version of BlackSilentPro fans. They operate at 12V DC, use 1.20W power, and start at 4.5V. The RPM is 600 to 1500 at 12V, with static pressure at 1.420 mmH₂O. Airflow is 40 to 100 m³/h, and sound pressure is 8.1 to 23.7 dB(A). The frame is black and made of reinforced fibreglass PBT with a standard 120mm mounting.

The fan has a traditional black frame without anti-vibration pads. There’s no arrow indicating blade spin or airflow direction. The frame has a cutout on both sides for cable routing, creating a symmetrical design. Blades are transparent with a hint of light brown and made of high-quality synthetic material. The motor hub has a black sticker. The backside has a black sticker with brand details. Build quality is solid, using NB-Nano SLI2 bearings and NB-EKA P2 motor. Noiseblockers include Silicon SilentFrame and inserts for noise reduction, with a tool-less assembly mechanism for easy installation except on radiators.

Testing

Blacknoise sent 3 fans for each category to test on the Alphacool Eisbaer 360. We checked the fans’ thermal performance at different speeds using the Reeven Polariz fan controller. The Eiswind 12 fans operate at 12V DC, have a speed range of 55-1700 RPM, airflow of 63.85 CFM, and a static pressure rating of 1.66mmH₂O. We tested their PWM range, airflow at various speeds, and thermal performance at 50% and 100% speed, using sound ratings of 29 dBA per fan.

WARNING: If your primary requirement is radiator mounting or industrial cooling solutions, these fans may not be suitable due to their specific assembly mechanism designed for general PC use and enthusiasts.

Airflow

In our first test, we try to validate the manufacturer’s stated/rated airflow value. The rated airflow value is 75.3 CFM at full speed. In our testing, the airflow value reached 78.3 CFM, validating the rated airflow value.

PWM Range

600 is the lowest RPM achieved on this fan, exactly the rated minimum RPM of 600. The maximum speed of the fan comes to 1530 RPM. The rated maximum speed is 1500 RPM. The fan stops spinning below 4.5V and starts spinning at 4.5V, validating the rated starting voltage.

Thermals

The thermal performance of the fan was tested on this test bench:

  • Intel i7 6850k
  • Asus Rampage V Edition 10
  • Ballistix Elite 4x4GB @ 3000MHz
  • Alphacool Eisbaer 360
  • Samsung 840 EVO 250GB
  • Corsair AX 1200i

Tested Microsoft Windows 10 x64 Pro edition (build 1709) with Noctua NT-H1 paste. Fans are 50% and 100%, and the CLC pump is 100%. I used Asus RealBench v1.44 to stress test the CPU and RealTemp to monitor. First at stock clocks (3.6GHz, turbo boost up to 4.0GHz). Recorded delta temps (core max temps minus ambient). Then, overclocked to 4.3GHz at 1.350V, ran the stress test again, and noted delta temps.

At 50% of the speed, all the fans had the same performance delta with neck-to-neck performance. At 100% speed, these fans lead over the Eiswind 12 fans by 1.17°C. But they were in the same performance delta against the NB-BlackSilentFan XL-P.

Next, we overclocked the i7 6850k to the 4.3GHz. On 50% of the rated speeds, The BlackSilentPro, BlackSilentFan and Eiswind 12 were in the same performance delta. At 100% speed, the NB-BlackSilentPro PL-PS took the lead over the NB-BlackSilentFan XL-P and Eiswind 12 with a performance ratio closer to the NB-eLoop.

Acoustics

26 dBA was the reading of our Fonseo Digital sound meter, showing the better acoustic performance of these fans.
