How to fix my Mac mini heating up in sleep mode?

When the device is in sleep mode it heats up a lot. Only after turning it on does it get cool. Is this normal?

I've finally figured out a solution: set "Start Screen Save when inactive" to "Never" !

I used to have the exact same problem as you can see from my previous post. This setting change has put my M4 mini into proper sleep mode with wired mouse light turned off during the sleep mode. Please note, DO NOT turn on "Prevent automatic sleeping when the display is off". Otherwise, it will prevent your Mac going into sleep mode.

It seems this is a software bug which causes the Macs not going into the sleep mode if screen saver is activated and dynamic screen saver clips use a lot of energy (I can feel the case warming up quite quickly when running this type of screen savers).
