Perhaps your best bet would be to do some research & reviews on the Ryzen 7 1700, same for the many motherboards currently available which support the AM4 platform, & if after doing so still have specific concerns, perhaps ask then.
Fan support, or cooling support, on any system depends chiefly on the chassis you use & personal preference. The computer case you choose dictates the dimensions and maximum number of fans able to be mounted on it. Personal preference, i.e. budget, whether your system has adequate temps/airflow you're satisfied with (or not), preference as to noise, all & more play a role in type of fans used in any system, regardless if from AMD or Intel.
