Symptom
FPR-1010 appliances (running ASA software) operating constantly at a fairly high CPU temperature around 75-76 C. Since it appears that 76 C is the threshold for "Warm" rather than "OK" temperature, we are getting repeated log messages like:
%ASA-4-735015: CPU 0: Temp: 76 C, Warm
%ASA-1-735020: CPU 0: Temp: 75 C, OK
as the appliance bounces back and forth between 75 and 76 C.

Conditions
FP1010 while under zero stress is running 70+ C with no obstructions around, and a ambient temp of only 55 C.
Appliance is sitting on a blank shelf in customers office. There are no obstructions on any side or above the appliances.
Further Problem Description
The "Warm" threshold for the FPR-1010 should be 85C with the critical being 100C. If the readings are less than 85, the message can be ignored.
