Pros & Cons
Pros
- ✓ Adjustable 3-12V DC output dials fan speed to your noise/airflow balance
- ✓ 4-way splitter drives four 3-pin or 4-pin fans off one adapter
- ✓ 36W at up to 3A powers a full four-fan array without sagging
- ✓ 100-240V AC input works on any global mains standard
- ✓ 5.5ft total reach: 40cm AC lead, 90cm DC run, 40cm splitter
Cons
- ✗ 36W ceiling limits you to low-draw case fans, not high-static-pressure banks
- ✗ No PWM control - speed is set by voltage, so no motherboard fan curves
- ✗ Splitter runs all four fans at one shared speed, not individually
- ✗ No tachometer feedback, so fan RPM will not report to your BIOS
