I had the small fan for the pump reach the end of its life and I found a replacement that is very close to the OEM fan. Sunon Maglev MF50152V1-1000U-A99 is a 24V 1.08W fan that is 30.7db. The amperage for the OEM fan is a tough one to find a replacement.

Great photo of the other part that breaks on the chilipad. When the tubing connector does break from removing it incorrectly, take the screws off both sides and super glue the hook back together or add another material to replace it.
