MEG_Z890_ACE_-_IO_Cover.pcapng - for CPU Temperature, only look at the last block. That's where I changed the temperature. For the other blocks, I just selected the preset and tried to figure out how to get rid of the noise, but gave up. Here was my flow for when I did change the settings within CPU Temperature: -Select CPU Temperature -Select first color, change to #effec7 -Select second color, change to #2faced -Select third color, change to #dec0de -Select first temperature, change to 22 -Select second temperature, change to 44 -Select third temperature, change to 66 -Hit apply The noise from the CPU was so bad that I had no way of knowing what packets were from CPU temperature readings and which were from changing colors. Good luck analyzing those.
