I do not think that it is conductive. I was taught the following, use it
for, displacing moisture, remove grease and penetrate rust or loosen bolts
etc in Northern speak. It also leaves a coating over the surface to preserve
the item but this is not good for electrical contacts as they no longer make
a decent short. I imagine what happened is that the stuff either removed
what grease he had left in his fan or is coating some of the electrical
connectors on his board. I am pretty sure that it is not conductive or we
would not be spraying it all around a running car engine.
