End Cap IOB Temperature Improvement
IOB Tempertaure plots
The red curve is the IOB temperature before the modification of the minicrate as a function of time and the blue curve is the same temperature after the minicrate modification.
Comparison Table
The table below summarize the average temperature change after the minicrates were modified. On average the temperature went down by 4 degrees. The two problematic minicrates (West 5 and 7 which used to run above 60C are now running at 54C. The West IOB temperature seem to have drifted by a coupe of degrees in the last 4 days.
