Jedrexxx Posted October 1, 2021 Share Posted October 1, 2021 (edited) Hi, I decided to change ML120's to LL120 RGB fans on my H150i radiator. The problem is that speed of LL120 can't be changed in iCUE. Adjustment of RPMs with ML120 connected to the pump works fine. What am I supposed to do?

Latharion Posted October 1, 2021 Share Posted October 1, 2021 (edited) The H150i cannot distinguish one PWM fan from another so it should be able to control the fan speeds of the LL120 fans in exactly the same way as the ML120s. It also should not matter if the RGB aspect is connected to the Lighting Node Pro Hub or not as that aspect is independent of the fan speed control. Perhaps check that the USB cable was reconnected to the motherboard and pump as that is the part that controls the PWM fan speed signals (both the fan speeds and the pump).

c-attack Posted October 1, 2021 Share Posted October 1, 2021 Most of the time this comes up it's that the fan curve has not been properly applied. There are lots of people using LL's on their AIOs. If the issue is still ongoing, try and post a picture of the fan curves for us. Also note, the LL may not be able to do "zero rpm mode". Link to comment Share on other sites More sharing options...
Jedrexxx Posted October 3, 2021 Author Share Posted October 3, 2021 I reinstalled iCUE and seems like predefined profiles for cooling are working now. Sadly there's no Zero RPM option on LL120's. Link to comment Share on other sites More sharing options...
