Compatibility, installation & service
- Keep the combined fan current at or below the manufacturer’s 3 A maximum and do not exceed the upstream power/header rating.
- Confirm pinout and voltage before attaching non-standard fans; do not confuse 4-pin PWM with 5 V ARGB or 12 V RGB leads.
- Test fan restart and tach feedback at the lowest setting; a low-speed setting is not a substitute for temperature monitoring.
Service notes
Power off before changing connections. Keep the dial and connectors free of dust and moisture; discontinue use if the cable, controller, or connector overheats or is damaged.
