Fact is the OIL does as much cooling as the water, so any cooling to this will have a knock on effect, "high" temps of 90/93 do NOT kill head gaskets, it is for this reason I have bought some(air) oil coolers, with a stat sandwich plate.
I have been in 28C sat in traffic for 6-8 hours on occasion, I overhetaed but not the car.
I think imo if you have a alloy rad then all should be well.
I will be taking turbo water temps, before and after to see exactly what the situation is.
