If it's not possible to open the fan housing, then I agree with Dan Mahoney, trying black nail polish in several coats. It might not hold, flake off, but while insulating tape that gets into the fan could damage it, dry, flaked off nail polish will not. Should the nail polish hold, it was also easier to apply and looks better than any kind of tape. Related to tape or polish I can't comment on smoke or burn. I just suspect that this isn't a risk.
