Pros & Cons
Pros
- ✓ Reverse blade design shows the front face when used as intake, hiding the motor hub
- ✓ 71.8 CFM and 2.0 mm H2O static pressure suits radiators and CPU coolers, not just case airflow
- ✓ Wide 800-2100 rpm PWM range lets you tune between near-silent idle and full-load cooling
- ✓ Squama particle frame texture cuts turbulent flow noise while raising airflow efficiency
- ✓ Dual addressable RGB light rings sync to motherboard software with per-LED effects
Cons
- ✗ 34 dB(A) at the 2100 rpm ceiling is audible in a quiet room or open-air desk setup
- ✗ 5V 3-pin ARGB header required - older boards with 12V 4-pin RGB will not sync
- ✗ Three-pack of 140mm only, so 120mm mounts and small-form-factor cases are out
- ✗ Two light loops plus PWM means four cable runs per fan to route and hide
