I like to use OpenRGB to monitor operating temperature. The CPU fan reads the CPU temp, the window in front of my graphics card reads the GPU temp, and, for now, I have my keyboard reading the NVMe temp (just recently installed the NVMe). My mouse color is set by Piper/libratbag so I know what preset I’m using.
Glad it is working for you! We have a Lemmy community !openrgb@lemmy.ml too!
