It comes with one fan, but there are many fan mounting positions to allow for good airflow if needed.

so good cable management is all but impossible, and the space behind the keyboard is barely large enough for the 24-pin connector cable to fit, but the airflow is good and the thermals are nice.

The plain steel chassis has holes drilled in it, excellent airflow, allows tons of different fan configurations, and then just replace the dust filter to hide the mounting screws

Added a 140mm fan to the front for intake and using the fan that came with for rear exhaust with excellent airflow

I like these smaller cases by Cooler Master with great airflow
