I think it is normal, mine is the same. The fans are pretty noisy, and sometimes the bearings give up. You'll know when the bearing is gone because the noise is unbearable.
The sports luxury with 17 inch rims is a little bouncy also. Not exactly a 100% plush ride so coil overs may be the best solution but I would not buy without going for a drive first. Everyone has a different interpretation of a comfortable ride.
