I thought it was one system, but with two coolant routes for those two locations. Can it control which system is open/closed separately?

There are two separate loops. Reservoir and fill cap for intercooler is under the plastic shield.

Had radiators/intercoolers replaced after an encounter with a length of 4x4 on the highway. Shop didn't refill the intercooler loop.

I live in Florida so I would run distiller water with Water Wetter in my M3 race car with a splash of BMW coolant for the lubrication properties of the water pump.

As far as underwood temps, my God do they get hot.... Lol. I would say an aftermarket vented hood like my factory Porsche hoods had and race-cat or catless downpipes with jet hot coating or thermal wrap.

I can vouch for Jet-hot coating!! used it on two vehicles and their alittle pricy but it works and they have lifetime warranty
