I have the 32 core Max 16" and pretty much the same here. Not only does it not blast fans, it barely gets off of "idle" temps for 99% of tasks. The Apple Silicon chips aren't just more efficient, they have a totally different power/performance curve. It's very non-linear, with the CPU performing a LOT of work at or near the base line power draw. As an example, I do ML engineering, so I've played around running ML/Deep Learning workloads on here (all on CPU). Training neural nets is very heavy work for a CPU, and I can run a lot of jobs where the CPU is showing pretty much max usage and the temps will literally only rise 2-3 degrees. It's insane. And looking at the package power in ASITop shows only a marginal increase in wattage. Bought this machine on launch day and I've only had the fans turn on once... playing Borderlands 3 through Rosetta, which makes sense as that is stressing all these GPU cores + CPU pretty much to the maximum. Unless you are maxing GPU + CPU in unison the fans don't turn on, and the CPU temp will almost never get above high 50s.
What's even crazier, is after using this machine for normal productivity tasks for a day my peak package power was... 12W, with an average of 1.12W. There is simply no other chip out there that can do that.
