Time to pull a couple of spark plugs to see if you are running rich. If the plugs are dirty with gasoline, start looking for a cracked vacuum line around the intake manifold.

The 'fan' noise could be a failed forward engine mount, that is the one under the timing belt. A failed mount could let the crank wheel touch the sub frame under hard accelleration.
