ASA 5516 overheating?

Hi All,

I just installed a secondary firewall in act/standby setup and noticed that it seems to be overheating.

See the output of show env command below. It seems that the CPU is at 75* but the Chassis fan is just at 2600rpm. And this is on a firewall that just sits there in standby, 0% cpu usage.

 

On my other firewalls (that are actually doing stuff) the chassis fan is at ~4000rpm with 30* cpu temperature.
