All of the Apple silicon Mac’s are so efficient I wouldn’t worry about heat unless it’s the M3 max and you plan on fully loading the system at all times.
At work we have an army of M* machines and the 14 and 16” ones have no issues staying cool and performing well at all times.
Ironically I’m one of the only people at work with a PC. But most of the people who have an M* pro/max are our developers. They mostly live in windows land through a VM and their workload isn’t too intensive. It their machines barely get warm to the touch vs the 2019 MBPs they had before.
