Gen 12 machine with low heat is an exception rather than the norm sadly. It must be possible, since there are a few machine out there that manage to do it, but most machines right now are quite hot and has low battery life (compared to 11th gen), especially the P-series in thin-and-light form factor (I am writing this comment from Lenovo X1 Carbon Gen 10 with 1280P, which can't even match the Cinebench score of the frame.work)
