I just got my X1 carbon today. The major problem is that the CPU is overheating. It can easily reach to 90 degrees or even higher. (I already used XTU undervolted the cpu) The fan is always on and a little bit noisy if using the laptop even for performing some simple tasks such as open a web. It will turn so hot that i won't even able to reset my hand on the right side of the keyboard above the air outlet (the area next to "enter"). Since it is a new system, i need to restart it after updating and installing some apps. The system stuck at Lenovo logo screen during restarting a few times already. I think it was due to overheating. Long press the power bottom and restart it will solve the problem.
