M4 Pro 14 core can get very loud!

[Astrohunter]

Hi,

Just switched from M1 Mini to M4 Pro 14 cores, while stacking in Pixinsight, it sounds like F16 engine, I can even hear it downstairs. 😂
Didn't really expect that tbh.

On video it might seem quieter:

Wow, that does sound like the fans are going going full-blast. Yeah, I didn't know it could be that loud.

Mine never has been, but it sounds like you are running some very demanding software:

1.1 What is PixInsight?
Briefly, PixInsight is an advanced image processing software platform. It has been designed specifically for astrophotography and other technical imaging fields. PixInsight is a modular, open-architecture system where the entire processing and file handling capabilities are implemented as external installable modules.

PixInsight has been ported as a native 64-bit application to Linux, macOS and Windows operating systems. PixInsight is a strongly multithreaded environment able to exploit all processors and processor cores available on modern hardware.


I'm guessing it's the CPU cores that are being maximally used, but maybe it's the GPU cores (or both)? The "Activity Monitor.app" built-in to macOS could give you some insight into that. (It's in the Utilities folder within Applications.) Besides the main CPU window, there's the CPU History window (Command-3) and GPU History (Command-4) windows which may be interesting.

Didn't the fans run quite loudly on the M1 mini, also? With that software, it seems you could use a nice Mac Studio!

Pixinsight runs through Rosetta sadly, at least for now.

Activity monitor shows 100% CPU being used and I think all 64GB ram while stacking.

M1 was super quiet compared to this, but probably 3x times less powerful.

It doesn’t use GPU for stacking.

Mac Studio is too expensive, I got this one on a good deal for 1800£, which is already a lot for me.
