Well, LSI's response was hardly a solution or even useful:
I do not see anything in the logs that might indicates an overheating of the controller card. The 97 degree Celsius is still
withing the range of the temperature threshold of the ROC which will
be 115. The main temperature to watch will be the ambient temperature
inside the server which requires at least 200 LFPM of airflow from the
fans to stay at the required threshold. Please find these required
For the MegaRAID SAS 9270-8i RAID controller, the operating (thermal
and atmospheric) conditions are as follows:
Relative humidity range is 20 percent to 80 percent noncondensing.
Airflow must be at least 200 linear feet per minute (LFPM) to avoid
operating the LSISAS2208 processor above the maximum ambient
Temperature range: — +10 °C to +45 °C (with BBU) — +10 °C to +55 °C
(with LSIiBBU09 mode 1 through 5)
The parameters for the nonoperating (such as storage and transit)
environment for these controllers are as follows:
Relative humidity range is 5 percent to 90 percent noncondensing.
Temperature range: – 40 °C to +70 °C (without BBU) — 0 °C to +45 °C
Our unit's are providing 240LFPM of airflow on low-fan speed setting, ambients are 18*C and chassis temp is much the same - appears they aren't going to admit this is a manufacturing fault - no silicon should ever run at this temperature at idle.
