One thing that has not been mentioned so far is that the aquaero 5 also allows a controlled overload. The aquaero monitors each fan channel in several ways so it is almost impossible to damage them. Even a short circuit can be detected.

The persistent maximum load is 1.65A but short peaks can be much higher to ensure that pumps or fans will spin-up correctly. The allowed overload depends on its strength and time. If you exceed the limit only by a little the overload can last longer while a heavy overload will be only tolerated for a very short time.

In addition to that we also monitor the temperature. At 85°C the power is set to 100% to reduce the power dissipation. This way the temperature will be reduced very fast. Back at 65°C your initial settings will be loaded again. So if a channel is not able to handle the connected load it could mean that the power will always jump up and down. But it can also stop if the load is so huge that even setting the power to 100% does not help. In this case the fan channel will be deactivated at 95°C to avoid damages on the device.

In the end it means you do not have to worry too much about the startup power since it can also exceed 1.65A.
