Picked up my 1299 today. I'm still speechless.

Water boils at 100deg at 1 atmosphere - so at 95 it would be alright(just) - don't know about the boiling point of waterless coolant. Most cooling systems are pressurised so they can run at >100 deg without boiling because once it boils it isn't cooling anything much; so there's no advantage to lowering the pressure.
Coolant pressure / temp is largely irrelevant other than at some point it will blow the system up / boil respectively. Question is more how much heat it can sink. At higher temps the coolant will transfer heat to the air faster (bigger temp diff at the rad), but obviously the engine is hotter, which isn't so good for the engine. Bigger cooling system = lower temps, but more weight and drag. Balance to be struck somewhere.
