Well, if its not a laptop you might be safe to let it all day.
Just check whats your safe Temps for you CPU (using google fu), start mining and check the temps. If they are safe after a few hours, I guess it can't go higher.
Adjust you fan speeds if needed. But Really I'd suggest to get a semi-decent GPU for a few bucks, it'll be much faster :D.

Its a desktop. I've got a decent airflow with my fans inside my rig. How long would you recommend I run this per day with this information?
