Is it safe??

YES. The Auto detects the increase in usage of your system (depending on which fans we are talking about) and will change (increase) to decrease the temp. If your not noticing or even caring (too busy in FireFights, etc.) then your going to cook then fry the chips and well.. get ready to buy a new system.
