Pros & Cons

Pros

  • ✓ Reverse blade design routes air out the front, showing the lit face in glass builds
  • ✓ PWM auto-ramps 800-1600 RPM +/- 10%, so idle stays quiet under light load
  • ✓ 27.7 dBA rated ceiling keeps nine-blade airflow from dominating a desk-side case
  • ✓ Infinity mirror on sides and center plus ARGB on frame and blades
  • ✓ Eight rubber pads and a hydraulic bearing damp vibration through the mounting points

Cons

  • ✗ 27.7 dBA is a max figure only - no per-RPM noise curve published
  • ✗ No static pressure or CFM rating listed, so radiator suitability is unclear
  • ✗ Reverse blades only pay off in builds where the fan face is visible
  • ✗ ARGB needs a compatible 5V 3-pin header or controller, not included in the listing
