CAM should start in offline mode.
Cam should automatically start in offline mode, do the fan/AIO/LED controls, etc. Only then should it try to login. If you MUST, have it say it'll work with reduced functionality.
Controlling Fans, AIO pumps and LEDs should *never* require internet access. It should just work.
And yes, there's guest mode. Except many of us have had CAM stuck at the "Authenticating" screen, not allowing us to select it!
I agree.. I don't know how many times i have started my PC logged on started some heavy CPU usage process and walk away to come back and notice cam is still on authenticating.
I'm using a 9900k which gets hot enough but to not have the fans and pump working properly on AIO is inexcusable. I have 2 x62's one for CPU and one for GPU so i have twice the chance of something overheating with this problem.
