Should i keep my temps of the outside water the same and expect the inside temps to rise or should i stop switching out frozen water bottles and let the whole system rise to around 70?
It's unusual that the fermentation temp wouldn't be a little higher than the water in the cooler. Once the fermentation slows down, it usually equalizes.
