Since last weeks I’m having this error: LCD screen shows wrong temperatures in form of “N/A”. Always was working fine for me idk what happening.- i9 14900K.- RTX ASUS Astral 5090.- ASUS Maximus Z790 Apex Encore. VRM, DRIM transmissor, RAM temperature...

Hi all, when I turn off my PC, a light red appears in the GPU for a second. When PC is on all is fine and all green in GPU Tweak 3. I have Corsair HX1600i + Corsair Premium cable. That’s normal? 

While gaming CPU heavy games GPU is on 68 degrees and CPU around 88-93 degrees. I use a personal curve of fans.  Laptop: - i9 14900HX.- RTX 4070.
