The pump makes about 75 Bar, or about 1125psi.
Oil gets hot when pumped up to 1125psi.
The fact OEMs put those cheap ass rudimentary coolers says there is obviously some need.
The fact that Ford Motorsport put on a bigger, good "end tank" style says more. If iy weren't a worthwhile thing for FUNCTION as opposed to life-span of parts they'd same the weight, clutter and plumbing and simply swap out the rack more often.
They run a cooler and filter.
And talk directly with those who rebuild the things OEMs design at a re-manufacturer level and they'll say more or less this: At elevated temps the system makes, aggravated by low oil, liiiiiiitttle tiny crystals for as the oil cooks, and those crystals are abrasive compared to nice slick oil. The get under the teflon O rings in the pinion housing which on OEM racks run teflon on aluminum and the little microscopic roasted oil crstals gnaw on the aluminum. Eventually there'll be internal leaks in the pinion housing and loss of assist.
