Do the aftermarket coolers have thermostats? And if yes how well do they work?
I'm not interested in putting one on my car, but this is where my question for useless-to-me information led me.

My car is almost exclusive to track days so I didn't take it into consideration. My car uses Jackson Racing dual radiator oil cooler, so like gen2 cooler, it warms oil from coolant when it is cold. But I don't have a side by side data to measure the warm up speed. My unit does not have thermostats in the sandwich plate as it relies on the engine coolant, which already has thermostats, to cool oil. But I think regular jackson racing and perrin oil cooler both has thermostats in the sandwich plate to prevent oil from over cooled. My car runs at around 190F in highway cruise in 70F ambient temperature, 230-240F on track on 100F track days.
