Question about Apple Mac Mini – 2024

Hi, has anyone had the experience with using the M4 mini in the attic where temperatures quickly rise up, due to poor air circulation? I modded my gaming PC to run at 40 celsius (when video playback..) and it's still too hot, would the M4 make a big difference in terms of heat generation. I know that the M4 is the most efficient device out there but but does it keep your room cool under light/moderate workload ? Would the heat output be comparable to an old i-3 or to an i-7 for exmaple ? Thank you very much!
