Question should i set my aio cpu fans to turbo or full speed? (aio is in the front with 3 other front fans. 1 exhaust on the back)

trying to improve air flow while conserving energy at the same time

honestly the turbo works fine with a continuous run of 4-6 hours, but wondering what would happen if it was at full speed
