Compatibility and installation
Use the fan as a high-speed PWM unit and set a conservative initial curve. Verify header current limits, airflow direction arrows, and clearance to adjacent fins/radiator; do not infer low-noise behavior at maximum RPM from the published maximum rating.
- Disconnect system power before installation or rewiring, and follow the exact model manual.
- After assembly, confirm fan/pump operation and monitor temperatures before sustained workload.
