While your cover is drying have a look at your fan without the fascia on and what you are looking for are any objects that may obstruct the fan blades. Common causes of fan noise is the electrical flex cord that is attached to the fan that has moved over time and slightly touching you fan blade, it would sound like a tapping noise. With the fan switch in the off position you can use a broom to gently push the electrical cord to one side.
