Is there or is there not a problem with the oil cooler?

If you arent going to track the car, you don't need a cooler. You can't push the car hard enough on the streets to get it to any sort of concerning temperature. I don't think that hot days will make a difference.. Guys that live in warmer temperature climates and dont track the car - be patient and don't waste money until someone actually confirms that you need a cooler. Its not just money either... installing a cooler when you don't need it just adds things that can go wrong...rock through the core, loose fitting - boom and your engine wont be covered under warranty.
