Ideally and "as a rough rule of thumb" it is best if there are no substantial obstructions within a blade diameter of either side of the fan, as when they are that close they really impede the fans capacity to work - The blade ends up "stalling" (where they spin but all they do is stir up the same air - but don't actually make it move from on side of the fan to the other.

Just a thought regards Chooks
