Unless there is something rather unusual about your computer or it is in an inappropriate environment, then the length of time it can be performing a computation before doing damage to hardware is far longer than you are likely to want to wait.

I am using an older generation PowerBook (800 MHz processor) and have run computations far longer than 15 minutes with no apparent harm to hardware. What will occur with a PowerBook is the bottom surface will definitely be warm or hot to the touch. So, the main thing is to make sure there is adequate ventilation to keep it from overheating.
