I see higher oil temps at higher rpms also. I think the reason is that the
oil pump is a positive displacement pump which means the amount of oil
pumped is proportional to rpm. The cooler can not cool a greater flow down
to the same temp as a lower flow.

Other things being equal; higher flow results in a higher heat rejection
capability. It decreases the fluid side temp drop, which increases the
average temperature, and if the air temp is the same; increases the average
delta T from fluid to air, increasing the heat rejection. I know; it may
seem counterintuitive, but the thermodynamics works that way.
The increased rpm increases the hp a bit, and would increase the oil temp.
