Scenario-Based Fan Selection | Q&A

Which fans should I choose for high-performance radiators?

  • Use static-pressure fans to push air through dense fins (AIO/DIY rads).

  • Examples: Noctua NF-F12, Corsair ML120 (MagLev), ARCTIC P12.

  • Consider push/pull if space and noise budget allow; seal gaps with gaskets or shrouds to reduce bypass air.

  • Tune curves to water temperature (or CPU package) for steadier acoustics.


How do I build a near-silent PC?

  • Prefer large-diameter fans at low RPM (140/180/200 mm where supported).

  • Pick MagLev or FDB bearings for low noise over long duty cycles.

  • Examples: Noctua NF-A14, be quiet! Silent Wings 4 (140 mm).

  • Use PWM control and low idle targets; avoid tiny fans spinning >2000 RPM whenever possible.


What works best in a small/ITX case?

  • Prioritize slim (15–17 mm) or small sizes (80/92 mm) where clearance is tight.

  • If you need a 120 mm in cramped spots, choose 15 mm slim models (e.g., Noctua A12x15, Scythe Kaze Flex Slim).

  • Ensure the case has at least 80 mm intake openings up front/side; remove or choose low-resistance filters.

  • Add top/bottom helpers if thermals demand it, watching for dust paths and cable obstruction.


How should I plan for a glass side panel and lighting build?

  • Use ARGB fans at visible front/side positions; keep rear/top exhaust non-lit and quiet for balance.

  • Good examples: Lian Li UNI SL, Cooler Master MF120R, Corsair LL/QL families.

  • Leave a clean viewing border around front fans (reverse-blade options enhance aesthetics).

  • Power lighting via a SATA-powered hub/controller; match 5 V ARGB (3-pin) vs 12 V RGB (4-pin) correctly and stay within current limits.


Quick presets (copy-and-use)

  • Front mesh intake: Airflow fans, low-RPM curve.

  • Front filtered/closed intake: Static-pressure fans, moderate curve.

  • Top radiator: Static-pressure fans (push, pull, or push/pull).

  • Rear exhaust: Quiet airflow fan tied to CPU temp.

  • ITX tight spots: 15 mm slim or 92/80 mm; prioritize fresh intake paths.

  • Showcase build: ARGB front/side + PWM hub; quiet non-lit rear/top.
