Looking for CFM airflow requirements for Tesla T4

I am looking for the airflow requirements to keep the Tesla T4 operating at full performance. The T4 product brief says “The T4 supports bi-directional airflow either from left to right, or from right to left. CFM requirements are identical for both airflow directions.”

But it does not give the actual CFM required. In order to design a case to meet the thermal needs of the T4, I need to have the CFM requirements.
Or any other documents related to cooling requirements for the T4 card.
