small 24VDC fan sounds like a pig, just put 100Ohm resistor in series it will lower 24V down to 17V. Fan will lose some rpm and that squalling sound.

Don't use WD-40 use (in moderate) lithium grease.
This sounds like stepper motor is skipping steps. In your case it's Z axis motor.
I would suggest check wires and connectors on driver board. May be check 24V on that big green connector (top...
Small 24V fans running out of 24V screams like a pigs. Vibration isolation is one part of how to deal with excessive noise. You may try to reduce voltage to say 17V by using resistor (around...
