SGP/MFRSR/E6 - Elevated head temperature

The head temp gets higher than we we would like to see due to high ambient temperatures.  
The head is designed to operate at 40 deg C, and we like to see it stay within a few 
degrees of 40 deg C during normal operation.  When local conditions are hot, the head temp 
can ramp up during the day.  It is unknown what effect, if any, results from high head 
temperatures.  There is nothing obvious in the data to indicate problems.
