    Apparently WD-40 was the wrong oil to use. [Never put WD-40 in] any electric motor, even if the rotor is stuck from filthy dried-up lubricant! It not only removes any remaining lube, but it can melt coil wires (the lightly-coated copper wires twisted up in electric motors) and cause an electrical short.

    How do you lubricate a fan?

  • Remove the front grill of the fan.
  • Lay the fan down on a flat surface with the exposed face up.
  • Apply a light nondetergent household oil that is SAE20.

    How do I stop my axial fan from making noise?

    One solution to reduce the noise-generating disruptions to the inflow is to deploy an air straightening grill on the fan intake. Such grills, properly designed, can be equally effective with both axial and centrifugal fans. Their use does not impact fan efficiency.

    How does a fan silencer work?

    Generally, silencers are used at intake and discharge of fan installations for treating air borne noise. The noise control is achieved by means of absorption. The acoustic energy propagating through the silencer is effectively absorbed into the fiberous absorption material and converted into heat energy.

    Can you lubricate a fan motor?

    It is usually best to use silicone lubricant on electric fan motors because it doesn't get as old and cakey as oil-based lubricants do. It's also a must to make sure you're not using any type of lubricant that's too greasy or toxic because it can cause problems with the bearing and coils in the motor.
