Pros & Cons
Pros
- ✓ 95.5 CFM airflow and 1,700 RPM top speed from a single 140mm PWM fan
- ✓ 3.46mm-H2O static pressure handles radiator fins and dense heatsinks
- ✓ Daisy-chain design collapses multi-fan builds to one PWM and one ARGB header
- ✓ Zero RPM mode cuts the fan entirely when your system runs cool
Cons

- ✗ Eight-LED ARGB needs a compatible +5V motherboard header to light up
- ✗ No inline controller included; lighting depends on your board's software
- ✗ 140mm size rules out cases and radiators that only accept 120mm mounts
