Does seem a bit hot that, is it overclocked?

I know that mine used to get to about that when it only had the stock heater on and as mild overclock, I addded water cooling O/C'd it a lot more and its nice and cool.

Check out the max operating temps for the CPU, you may be able to adjust the levels of the alarms on that app.

BUT

I would recommend getting a better cooler for the CPU that way it will be running cooler and not thermally stressing out the CPU as much. as 70 seems way way high to me.
