You would need to measure cubic volume of room to calculate/select a suitable fan size. It is more than likely that the ventilation hole will need to be increased, but providing the electrical part of the circuit was done correctly originally then that would be reusable.
Also the type of fan will have a bearing on its efficiency.
Generally a centrifugal fan will shift more air than an axial fan, but there is a physical limitation on the amount of air you can get down a 100mm duct.
The length of the duct will also have an effect.
This calculator will help you determine the fan performance requirements
