Depending on model, I guess. My 2 year old x360 has so bad airflow for cooling that I've had multiple "meltdowns" if I forget to put a spacer underneath it. Basically the whole thing shuts down and won't boot again for an hour, and the underside is painfully hot. A pencil underneath the screen hinge works best for keeping enough airflow to avoid this. The first time it had a meltdown, my touchpad stopped working completely, so I went with an external mouse. Second time, the touchpad melted itself back into place I guess, so now it works again.
