There are restrictions on the no-fan state during Power Nap, so it’s still possible that a Power Nap activity could cause the fan to spin up. Apple hasn’t yet listed what the restrictions are, so if you have a new Mac Pro, let us know what you’re doing that causes the fans to spin up during a Power Nap.
