Recently, when opening iCUE, I found that I was not able to control any of the fan speeds at all. After looking around for a bit, I noticed that all 3 rails (12V, 5V, 3.3V) show up as "0.00V". The fans (LL120s) on my case are physically spinning, and the RGB on them are working, but I can only control the lighting.
I looked at the graphs, and there appears to be normal voltage for the first few minutes of turning on my PC, and then none at all (all 3 graphs show the same effect). (att 1)
And looking in HWINFO64, the voltages are going all over the place. (att 2)
I've tried re-installing iCUE, and even re-installing Windows (I had already planned on doing a fresh install anyway, so it wasn't too out of my way at this point). Issue is still there.
