Anyone having shutdowns from heat problems?

is your console possibly over heating, the system will shutdown from over heating to protect the hardrive

This could be in combination with the console expelling residual heat after shutdown.

You can check if your Xbox is heating up abnormally, this can cause a shutdown for safety.

Hi!

Has the console suddenly shutdown while you were playing?

In this case, make sure the console is placed in a ventilated place. Due to the heat, the fan may become clogged and cause an unexpected shutdown.

You can blow compressed air through the vents to ensure the unit is as clean and dust free inside as possible. Do this with the unit off.

Unexpected shutdowns are either due to heat or the unit thinking it is over heating.
