Under load, an Intel i5 8400 computer using the factory thermal paste achieves 63 degrees Celsius with only slightly audible fan noise. The temperature stays about 50 degrees and there is total silence during the games. For a thermal design power (TDP) of more than 65 watts, I would look at models with a copper core or a tower (assuming the risk of blowing a VRM or SSD is not something that can be tolerated).
