Thank you all very much for the input. Yes, i had read that actually mining 24/7 on a laptop would probably fry it, but the idea here was to mine only for a part of the day to get to know the process and better understand the cost-efficiency doing it. Mining ETH, i hadn't thought of that, will give it a try! I already played a little with the voltage control, and had some interesting output. I'll research some more and see how it goes using the MSI afterburner, which works like a charm for the temperature and clock/voltage control, and will share my experience. Any other contributions would definitely be welcome
