Ok thanks. I'm officially scared Af to play my system.1. Usually it means that its dying. The other possibility is that the thermal paste/solder is beginning to crack causing less contact between the GPU and the heat sync meaning even if the fan is fine, the system will overheat. This will eventually lead to a YLOD and need a fix regardless.
2. Unplugging it won't cause a problem.
