Yes, custom curves cause this issue. It's likely not a harware issue. but I want custom curve for more quite setup :D:

This happens to me as well. only after I wake my computer from sleep mode after a long time. I have to restart the service TWICE to get it back to working.

Fans don't have to run aggressively on water cooled system, it wont damage your CPU if fans are not running according to the curve. In my experience fans did not stop in any scenario, for me they actually run faster when iCUE freezes. The CPU also protects it self from being damaged if it reaches very high temps.

@Greybeard Thank you very much, hope it gets fixed soon. After logging for long time (a week or two), here are the errors that caught up. not sure if it helps but i post it in case if it helps. I did run other monitoring software's during this process sometimes. but i believe iCUE should be immune to crashes (that's when you use try-catch statement!)
