Can a magnet damage the bearing on a fan?

post #1 of 7
Thread Starter 
I was replacing the fan on my psu and I noticed that when the fan is put against the casing it has a magnetic attraction between it and the center of the fan. I'm just wondering if this could actually damage the fan in any way?

Motors use magnets internally along with electromagnets to create the torque to spin the fan.

Well no, it's not going to damage the bearing.  But yes, there should be a little magnetism near the center of the fan.

I think it is like of using magnetic tipped screwdriver to screw in your motherboard/HDD/Optical, while the screwdriver is magnetic it is not strong enough in most cases to damage anything.
