Problem with high flow sensor NEXT

Tuesday, August 25th 2026, 4:13pm

Hi everyone, I built my first liquid-cooled PC.
I have fans connected to the OCTO and a high-flow sensor, but the flow reading only shows up when I set the pump to 100.
It’s a D5 pump in an EKWB distribution plate.
I don’t know what could be causing this,
and I also don’t know how to configure all these fans, so I’ve left them set to 30% in auto mode.
I have the Octo USB, the fans, and that temperature cable connected. The flow meter is connected separately via a USB cable.

Your loop maybe a bit restrictive, only getting a flow rate of 35 l/h at full power.
The high flow next sensor "delivers reliable readings over a wide range of flow rates between 35 l/h and 1000 l/h".
