Safe rendering Techniques

Hey there fellas, I just finished a huge, 2,200 frame animation in cycles spread out over 10 documents and I was wondering if you could give me some tips on rendering techniques. I was thinking about rendering maybe 4 at a time, 2 on GPU and 2 on CPU to split the load and I was wondering if this is gonna be a safe rendering technique considering the fact my laptop will be running 100% of the CPU’s capacity over the course of about 30 hours. I’m really worried about my CPU overheating and getting fried… not much of an expert when it comes to hardware so do you think there’s the chance I could damage my CPU during this render? It gets really hot sometimes…
