I thought I had received a defective unit when I realized it, I have also noticed that the fan corresponding to the CPU side kind of draws less air through the lower grilles on its side. I have tested this at full load when playing by executing the ventilation to the maximum in the ACC, in addition to the fact that in ACC since I updated to W11 it does not allow modifying the power profiles and you have to do it from the windows configuration. I got your comment because I started looking for information about the problem you initially commented on.
