Turbo is not 100%, although more aggressive than standard. The pump needs 12v at all times. The Asus terminology for 100% is "Full Speed" when in the EZ BIOS or "disabled" when in the Advanced BIOS -> Monitoring section. Both lock the fan header at 100%/12v. Manually moving the dots up to 100% can work, but the proper Full Speed/Disabled setting will prevent other BIOS features from overriding that setting. When you have it on a curve, there is always the possibility the pump won't start because the voltage is not high enough. Also, running it at below voltage specifications is more likely to cause longevity issues.

The pump speed on the H100i v2 is about ~1950 rpm for Quiet or 2800-2900 for the higher speed setting. If you see pump values like 1500 rpm, you know something is not right and that is the first thing to check. Reducing the voltage to the entire unit will also cut voltage to the fans and you likely don't get the speed you would expect for a given setting.
