My work laptop is a MBP M1 Max, all development is local and I've never heard the fan or feel the heat like my previous work MBP Intel (Core i9). That machine sucked, it had the power but I could never be work for more than 2-3h away from a power outlet. The M1 Max lasts 7-10h even when doing Google Meet video calls (the biggest power drain I experience, much more than development running multiple containers with Rancher Desktop).
