Arctic P14 PST PWM
5 sources1 derived$12.74as of Oct 1

Arctic P14 PWM PST fans deliver exceptional value in the low-end segment, with HWCooling.net praising their high airflow-to-noise ratio and efficiency through obstacles. The design features five large curved blades optimized for performance, while the PWM PST variant supports both pulse control and daisy chaining. hwcooling.net notes the fans' affordability and strong results, though they warn of potential blade-frame contact issues due to flexible materials and a small hub that may affect longevity. These fans are ideal for budget-conscious users seeking efficient cooling solutions.

Strengths
  • — Achieves top airflow per unit of noise among 140 mm fans
  • — Features five large curved blades for efficient airflow through obstacles
  • — Includes PWM support with semi-passive mode (0 dBA at low duty cycle)
Watch-outs
  • — Blades are made from relatively flexible PBT material that may contact the frame
  • — Small impeller hub (41.6 mm) may reduce robustness and lifespan

Lian Li Uni Fan SL120 V2 Standard
4 sourcesall derived$58.5as of Oct 1

Lian Li Uni SL120 V2 fans deliver excellent build quality and installation methods, with a clean RGB implementation and improved cable management. STS Tutorial noted these fans offer best-in-class construction and a daisy-chaining capability that supports up to six fans per cable. However, the performance metrics were slightly behind Lian Li's AL120 V2 models, and they didn't outperform the Uni SL Infinities. The fans feature a proprietary controller system with 4-pin PWM, 3-pin ARGB, and USB 2.0 header connections, allowing for flexible mounting and control options.

Strengths
  • — Best-in-class build quality with sturdy black frame and fan wing
  • — 2x RGB lines across fan frame with clean, no-visible-LED implementation
  • — Daisy chainable up to 6 fans with single cable control
Watch-outs
  • — Max performance could be better than competitors
  • — Did not outperform the Uni SL Infinities

How they stack up

Arctic P14 PST PWM

The Arctic P14 PST PWM offers the best airflow-to-noise ratio among 140mm fans. While it lacks RGB lighting and daisy-chaining capabilities found in the Lian Li Uni Fan SL120 V2 Standard, its budget-friendly price makes it ideal for those prioritizing performance over features.

Lian Li Uni Fan SL120 V2 Standard

The Lian Li Uni Fan SL120 V2 Standard leads in daisy-chaining capability with support for up to 6 fans per cable, a feature not available in the Phanteks T30 R PST or Thermaltake Riing Quad 12 RGB Radiator Fan TT Premium Edition. While it offers excellent build quality and clean RGB implementation, it doesn't match the airflow performance of the Noctua NF-A12x25 chromax.black.swap or the Phanteks T30 R PST.
