M1 Max vs M1 Ultra Cooling Systems Compared (MaxTech Video)

As usual a clickbait header from MaxTech, the 91 degrees temp relates to the MacBook pro not the Mac Studio.

Seems like Apple has done a great job designing the Mac Studio. Both the M1 Max with it's aluminium heat pipe, and the M1 Ultra with it's copper heat pipe seems to be offering way more cooling capacity than needed. This is great as it will make the fans never spin beyond ~1300 RPM it seems.

I do find it rather strange for Apple to have the fans running at ~1200 RPM idle/minimum. It doesn't look like it's need at all. It almost seems like it could be passive while idle/low load. This can obviously be tuned with upcoming firmware and software updates. Some might also argue that Apple should allow for both the CPU and GPU to draw additional power as it seems like there is so much headroom for the cooler. No real need to limit a desktop system to such a low power usage if you have ample cooling capacity. But it might be that the Apple M1 Max and M1 Ultra doesn't scale all that well with additional power, or Apple simply wants to ensure that the Mac Studio is not going to be noisy regardless of how much load you put on the system.

Whatever the reason, I hope it's engineering driving the decisions and not marketing.

I was running a Handbrake re-encode yesterday on my Mac Studio with M1 Ultra and it pegged all of the CPU cores at 100% and ran for about 5.5 hours to complete. After a couple of hours, the CPUs hit 78-degrees C and everything else was considerably cooler. The fans never spun up past their idle speed of around 1,350 rpms and the Mac Studio remained quiet. Feeling the enclosure, I found that there was just enough warmth to be detectable and this is the first time that I’ve ever felt the enclosure not feeling cool to the touch.

So, the system so far has maintained very reasonable temps, even when under a considerable load over a long duration. It appears that it has a very well-designed cooling system.
