How much activity is there on those cards at the time of the screen capture? A fan would help especially if the main one fails.

But with regards to overheating (from system doc):

Notes:
• To prevent the system from overheating, no
more than 30% of the FXS ports should be
active simultaneously per 32FXS card and no
more than 50 FXS ports per system.
