The 12V rail’s OCP triggering points are below 130% but are identical under cold and hot conditions. Typically, there should be a notable difference between these two conditions. On the minor rails, the difference in the OCP triggering points between the normal and hot temperatures is high enough to protect the PSU effectively.

The over power protection has similar triggering points under normal and hot conditions. They are not highly set, but I would still like to see a significant difference between them.
