iMac M1 Fan noise normal?

[palle22]

Hi,

I'm on my second iMac M1 2021 7 core.

The first one was quiet as a mouse, even during gaming. My new one has a lot of noise from the fan when gaming, and I wonder if something is wrong with it, and I should turn it in for repair? It's still under warranty.

Does your iMacs have the same issue?

My 8 core M1 is completely silent. I don't play games, and the fans have only spun up 1-2 times since I got the machine, but when they did they sounded like a whoosh. I can't speak to the 7 core model. If I heard that sound coming from my machine I would be alarmed.

Open Activity Monitor. If all your high-performance cpu cores are utilized for a long time, this kind of fan noise is absolutely normal.

Ok, thanks. Seems like it's the GPU-load that causes the noise...

I suppose I'll just have to live with that, if it's not an error. Strange, though, why my previous machine was quiet during gaming

Maybe you switched on some graphics setting, which requires way more computation?
