Loud mp40 motor

So I just made the jump and bought the Vortech mp40 for my 75 gallon. My 2 small issues r the actual motor is a little loud. I have it on the short pulse mode and every time it ramps up I can hear it. It's not loud but annoying me. I can't hear it with the tv on but when it is all quite I can hear clearly. Any chance it just needs to break in a little and this will go away?



The other thing is the motor is warm. I only have the pulse at 50% with the pulse interval a notch shorter. Just want to make sure this is normal and the motor isn't defective.



Today is day 4 of having it running.
