What this fan is for

This 90 mm × 25 mm DC fan runs at 12 V and draws 3.83 W. It is built for CPU heat-sink cooling inside a computer case and suits builders who need a direct replacement for the Sunon EF92251S1-Q100-S99 model.

The spec that decides fit

The four-pin PWM power interface and 90 mm square frame with 25 mm thickness determine whether the fan mounts on your existing cooler. Verify those dimensions and the 4-pin connector before ordering.
