Is that really profitable? Mining with CPU? By using your CPU on 100% you will soon damage it. CPU is not made for 100% power for a long time.
Are you sure about this? I have a few software that use close to 100% of the CPU, and I need to run them quite frequently for my regular job. My laptop is 4 years old and till now it hasn't shown any signs of damage. On top of that I have also used this same laptop for mining multiple altcoins (both PoW and PoS), during the last 2 years.
