Oil cooler fan sucking or blowing?

[BenGTR]

To prevent very high oil temperatures, I would like to mount a fan to the oil cooler like this:

I'm guessing when the car is moving, the air will flow inside through the sidepods and then exit the engine bay somewhere else. If this is correct, the fan should suck air? So that it won't work against the airflow?

What do you think?

Thanks for your input

Actually the car is not yet finished, but from other cars experience I wanna stay below 120-125°C with track usage.

The fan should start when the water-fans start. Additionally, I wanna put in the "fan override switch" and connect the oil-fan to it.

Or do you have other suggestions?

In this case I don't buy a fan?

Thought of Stigs page, but if it doesn't help at all I don't have to spend money and time for it ...
