Questions about this item

Does the 04W1578 fan require periodic lubrication or bearing replacement?

The 04W1578 is a sealed sleeve-bearing unit; no user lubrication is needed and the bearing is not separately replaceable.

The KSB06105HA hits its fixed maximum RPM ceiling first; the firmware does not allow higher speeds regardless of temperature.
