Antec NOVA 120 120mm case fan fluid dynamic bearing 4-pin PWM

SKU CH-3N7J-ZJYY0

A 120 mm case fan with fluid dynamic bearing, 4-pin PWM control, 95.32 CFM maximum airflow and 38.7 dB(A) peak noise

  • Fan Counts1 Fan
  • TypeCase Fan
  • CompatibilityCase
  • Fan Size120mm
  • Fan Thickness25mm
  • Bearing TypeFluid Dynamic Bearing
  • Fluid dynamic bearing runs quietly at 38.7 dB(A) max
  • PWM speed range from 300 to 3200 RPM for flexible cooling
  • 32 CFM maximum airflow moves heat fast
  • 56 mmH2O static pressure pushes air through dense fins
  • Standard 120 mm by 25 mm frame fits most cases

Build fit

The 120 mm frame and 25 mm thickness match standard case mounting points, while the 4‑pin PWM connector allows motherboard speed control without extra adapters. Fluid dynamic bearing reduces friction, freeing up acoustic headroom for quieter operation at similar airflow.

Sustained behaviour

Three preset speed bands (L 300~1500 RPM, M 350~2400 RPM, H 400~3200 RPM) let the fan run at lower RPM for long periods, keeping noise near 38.7 dB(A) while still delivering up to 95.32 CFM and 6.56 mmH₂O when thermal load rises.

Questions about this item

How long can the 120 mm fan sustain 3200 RPM before the fluid dynamic bearing becomes the limiting factor?

The fluid dynamic bearing is rated for continuous operation across the full H mode range of 400 to 3200 RPM with a ±10 % tolerance, so sustained use at the top speed stays within the bearing's design envelope.

What noise and heat output should I expect when the fan runs at its maximum 3200 RPM setting all day?

At the highest H mode speed the fan reaches 38.7 dB(A) maximum noise; heat added to the case is negligible because the motor draws only a few watts through the 4-pin PWM connector.

Which motherboard header or controller do I need to drive the 4-pin PWM signal on this 120 mm case fan?

Any standard 4-pin PWM fan header on a modern motherboard or a dedicated PWM fan controller will provide the required signal and power for the NOVA 120.
