I believe the pump speed of the Eisbaer is supposed to be 2600RPM. My pump at 100% reads over 3000RPM in fancontrol in Linux and in multiple apps in Windows. Do I need to cut power to slow down to 2600 or below to maintain longevity of pump. Or, is it being read incorrectly by both OS ? It also reads higher @90% PWM than it does @100% PWM in both operating systems if that matters.
