Questions about this item

Will the 24 V 0.41 A rating of this TA450DC fan work with a legacy 12 V fan header?

No — the fan is rated for 24 V and draws 0.41 A, so a 12 V header cannot supply the required voltage.

How can I confirm the B34978-55 unit is spinning correctly after installation?

Check that the 12038 model runs steadily at its rated 24 V supply and listen for smooth airflow without vibration.
