For anyone who is interested; I’ve just installed a different heatsink. The temperature (LED off) was stable at 64,5-65,5c before the switch and is now 54c without the LED after the switch.

What you need if you want to replace the heatsink:

1. T8H screwdriver for removing the 4 screws on the bottom of Homey
2. Wrench size 5 for removing the 4 hex nuts from the heatsink
3. Thermal pad with thickness of 1mm for the CPU and 3mm for the Ethernet controller (I used 21W/mK)
4. Heatsink with longer fins. They are 11mm height instead of 5mm. (21gram instead of 11)

I don’t know if I am allowed to share direct links to a shop but you can find them (on AliExpress) and some pictures below could be helpful.

Heatsink (black and blue available):

Edit 2023-05-19: When adjusting the nuts (how ‘strong’ they are tightened), you can manage it to lower the temp to ±52c. (room temp 24c):
