Would Artificial Super-Intelligence From Science Fiction "Speed Up" The Brain and Wear it Out Faster Leading to Earlier Death?
Our brain runs on a series of chemical and electrical reactions running at a stable pace. Unlike computers, you cannot "overclock" the brain into running these reactions any faster than normal. 
However, if we were to assume the psuedoscience to be true, it would be logical for the brain to undergo premature death. With the rates of these reactions increased you would see the rate of DNA mutations increase along with the amount of oxidative stress. All of which are causes of cancer and cell death.
