Both.  High temps at the inlet indicate insufficient cold air.  High 
temps at the hot sensor indicate poor airflow - think airflow 
restrictions, failed fans, etc.

Consider using SNMP to track these.  You should then be able to pull the 
warning and critical thresholds on a per-card basis to know when you're 
running hot.
