I'm getting high velocity in the shroud region I have attached my input file and geometry/result animation pictures for reference. Could you please let me know what's wrong with my model if possible?

    My first guess is that you need to move the pipe surface attached to the fan volume into it's own No-Slip boundary set, such that it doesn't get the reference frame applied to it via the Auto/Default Wall process.  If you look at the pipe wall and see the angular velocity due to the fan reference frame definition, that is likely the cause.
