The cheapest fans available often have a lot of injection molded plastic that squeezes out of the gaps of the metal mold when the plastic parts are formed. Removing this may help some.
The cheapest fans now come with the small motor shaft embedded into the frame with a tiny ball of metal formed at the end of the shaft. The ball is what prevents the shaft and fan blade portion from coming out of the housing. This type of bearing and retention cause more friction than a design that uses a bushing and a small plastic retainer ring. They type with the retainer ring are usually floating in the magnetic field. The little plastic retainer ring on the shaft end is only present in cases where the fan is dropped causing more force than the magnetic field will hold onto. If a person such as yourself, presses on this type of fan at the fan blade hub, you will feel the magnetic field and see the hub deflect and then return to the center of the field. Spinning it will feel frictionless. With the ball shaft type, there is little deflection and it feels like a bit more friction when comparing two side by side.
With the ball shaft type, most of the noise will be coming from the friction and transmitted through the body of the enclosure. If you isolate the fan with some damping between it and the enclosure it will reduce the noise considerably. Damping the enclosure, and adding rubber feet between any table or surface may also help.
Hello, Thank you very much for your detailed reply, it has been very helpful. I was just worried that the printer would break. Best regards.
