Available as standard 120 mm and 140 mm fans, or single-frame 360 mm and 420 mm designs that install with just four screws and one 8-pin connection.

  • Whisper-quiet operation under 37 dB at full speed
  • Precision-engineered blades and tight frame for high static pressure
  • Single-frame F360U and F420U install with four screws and one 8-pin connection
