The NB-BlackSilentFan, a popular fan from BlackNoise since 2005, belongs to the IT series for PC users. The XL-P version in the 120mm category operates at 12V DC, using 2.64W with a starting voltage of 4.5V. It offers a variable RPM range from 1000 to 2000, providing airflow from 40.6 to 75.3CFM. The fan’s static pressure is 2.790 mmH₂O at 12V, producing a sound ranging from 13.1 to 31.7 dB(A) at 100CM.

Here is the listing of their entire BlackSilentFan series of the fans:

The fan features a classic black frame made of reinforced fiberglass PBT material. There are no anti-vibration pads on the corners, and it has a standard 120mm mounting clearance. The frame lacks arrow indicators for spin and airflow direction. The 7 transparent blue blades are made of high-quality synthetic material by Bayer with an anti-dust surface. The motor hub has a black sticker with Noiseblocker branding and a website address.

The backside of the fan includes a black sticker covering the motor hub, with printed information on ultra-quiet operation and RoHS conformity. The 4-arm assembly connecting the motor hub with the frame ensures rock-solid build quality. The fan uses NB-Nano SLI bearings and NB-EKA P2 motor. Each fan has a 50cm sleeved power cable and anti-vibration mounts called NB Slics. While no screws are provided, the fan is suitable for PC chassis airflow or heatsinks with fan mounts provision using NB-Slics.

PRO TIP: The NB BlackSilentFan XL-P is an excellent choice for budget-conscious users seeking a silent and high-performing fan with a classic design.

Testing

Thanks to Blacknoise for sending 3 fans in each category for testing on the Alphacool Eisbaer 360. The NB BlackSilentFan XL-P showed high airflow and good static pressure values when tested against Alphacool Eiswind 12 fans. Eiswind 12 fans operate on 12V DC, with a speed range of 55-1700 RPM, airflow of 63.85 CFM, and 1.66mmH₂O static pressure. Testing included airflow profiles, PWM range, and thermal performance at 50% and 100% speeds using a Reeven Polariz fan controller.

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 my testing, the airflow value comes to 78.3 CFM, validating the rated airflow value.

PWM Range

Next is the fan’s PWM range and the corresponding airflow values. 810 is the lowest RPM achieved on this fan, below the rated minimum RPM of 1000. The maximum speed of the fan comes to 2100 RPM. The rated maximum speed is 2000 RPM. The fan stops spinning below 4.5V and starts spinning at 4.5V, validating the rated starting voltage.

Thermals

Tested Microsoft Windows 10 x64 Professional edition build version 1709. Used Noctua NT-H1 thermal paste. Set fans to 50% and 100% speed and CLC pump to 100%. I employed Asus RealBench v1.44 to stress test the CPU. Monitored temperatures with RealTemp. First, run a stress test with XMP at stock clocks (3.6GHz, turbo boost 3.8GHz, Turbo Boost II 4.0GHz, 1.16V VCore). Recorded delta temps. I overclocked the chip to 4.3GHz, 1.350V VCore, loaded XMP, and ran the stress test again, noting delta temps.

WARNING: If you prioritize RGB lighting or require arrow indicators for spin and airflow direction, this fan may not meet your specific preferences.

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

Here are the results.
