Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

The Noctua NF-S12A ULN is a 120 mm case fan engineered for ultra-low-noise operation in desktop PCs. It belongs to the third generation of Noctua's S12 series, offering improved airflow-to-noise efficiency compared with its predecessor. The ULN (Ultra-Low-Noise) variant provides very slow rotational speeds for near-silent performance while still delivering effective case airflow and reliable long-term operation.

Advantages

The NF-S12A ULN features a refined blade design with Anti-Stall Knobs and an Advanced Acoustic Optimisation (AAO) frame to increase aerodynamic efficiency and reduce noise. It runs at 800/600 RPM speed settings for minimal acoustic output, uses a SSO2 bearing for smooth, durable operation, and comes from Noctua's established quality standards for reliable cooling components.

Suitable for

  • Silent or near-silent PC builds
  • Home theatre PCs and media centers where low noise is important
  • Workstations in noise-sensitive environments
  • General case cooling in desktop systems

Key specifications

  • Type: Fan
  • Fan diameter: 120 mm
  • Rotational speed: 600 / 800 RPM (ULN settings)
  • Airflow: 74.3 m³/h
  • Minimum static pressure: 0.44 mmH2O
  • Operating voltage: 12 V
  • Colour: Brown

How to use

Install the NF-S12A ULN into a standard 120 mm fan mount in your PC case, aligning the airflow direction arrow on the frame with the desired intake or exhaust orientation. Connect the fan to a 3-pin or compatible motherboard header or fan controller supporting 12 V operation and select the ULN 600/800 RPM setting if available on the controller. Ensure screws or anti-vibration mounts are used to secure the fan and reduce mechanical noise transfer.

Recommendations

The fan is designed for applications where minimal noise is the priority. For improved cooling under higher load, consider using higher-speed variants of the S12A series or combining the ULN fan with additional intake/exhaust fans while monitoring case temperatures.
