I would think a cross groove joints would run hotter than a fixed joint with them both running at say 20 degrees. The balls in a fixed joint move in a circle in a plane that is at half the angle of the axle. The cross groove balls move in an ellipse. So they travel farther each rotation which is why I would think they run hotter.
The other heat generator is the side loading on the cage that the angled grooves produce. Non-plunging's do not need heavy duty 300M cages.......
