Holes In Bottom Of Air Pump

[VespertineStar]

Hi

My air pump is quite noisy but I have found the source of it. There are four small holes on the bottom of the air pump which seems to be some sort of vent. If i cover the vent with my finger the air pump becomes near silent and still seems to work. There is a slight air flow from the holes. Can I cover these holes or will it kill the pump if i do?

Could be there to allow the motor to cool - it might overheat.

Yeah I thought as much.
