If it’s mainly a street car then I see no reason to run the fan or the pump when you turn the car off. Even if you did. As soon as you turn them off the temps are going to go right back up from the heat coming off the motor. You may as well just start the car and drive 5 minutes and you’ll be back to normal temps. Plus the fan doesn’t do a great job pulling air through the exchanger. The fan is meant for the radiator not the exchanger. The exchanger relies on air hitting it from the front.

If your at the track. Then that’s a different story. Then a large trunk tank with ice is what you need or an interchiller. Or simply opening the hood and running a jet fan on the motor.

So there's really no avoiding it is what you're saying and it's a fruitless venture on anything other than a track car... If that's the case then perhaps there really is no point in exploring this stuff any further and just accepting it for what it is. (No sarcasm intended btw)
